Police stations must have functional CCTV cameras

Police stations must have functional CCTV cameras

The premier investigating agencies comes under the scanner of CCTV. The Supreme Court today (December 2, 2020) directed Centre to install CCTV cameras and recording equipment in the offices of Central Bureau of Investigation (CBI), National Investigating Agency (NIA), Enforcement Directorate (ED), Narcotics Control Bureau (NCB), Department of Revenue Intelligence (DRI), Serious Fraud Investigating Office (SFIO) & any other agency which carries out interrogation and has power of arrest.

Supreme Court through its judgement dated December 02nd, 2020 emphasized the pressing need for all State Police Forces to implement IP based CCTV surveillance system in each police station of the state / UT in order to prevent unlawful activities, ensuring safety of its citizens and also to efficiently deal with the cases involving allegations of torture in custody.

The Supreme Court has passed directions for constitution of “Oversight Committees” at the State (State Level Oversight Committee) and District (District Level Oversight Committee) level for ongoing installation and maintenance of CCTVs in Police Stations across all UTs and States while it directed Finance Departments of all UTs and States to allocate fund for it. 

The State Level Oversight Committee must consist of:
(i) The Secretary/Additional Secretary, Home Department;
(ii) Secretary/Additional Secretary, Finance Department;
(iii) The Director General/Inspector General of Police; and
(iv) The Chairperson/member of the State Women’s Commission.

So far as the District Level Oversight Committee is concerned, this should comprise of:
(i) The Divisional Commissioner/ Commissioner of Divisions/ Regional Commissioner/ Revenue Commissioner Division of the District (by whatever name called);
(ii) The District Magistrate of the District;
(iii) A Superintendent of Police of that District; and
(iv) A mayor of a municipality within the District/ a Head of the Zilla Panchayat in rural areas.

Salient features of Supreme Court Judgement in respect of CCTV surveillance of all Police Stations in the country.

  • CCTV cameras should be installed at each and every Police Station and no part of a Police Station should be left uncovered, it is imperative to ensure that CCTV cameras are installed at following locations:
    Entry and exit points, Main gate of the police station, All lock-ups, All corridors, lobby/the reception area, All verandas/outhouses, Inspector’s room, Sub-Inspector’s room, Areas outside the lock-up room, Station hall, In front of the police station compound, Outside (not inside) washrooms/toilets, Duty Officer’s room, Back part of the police station etc.
  • CCTVs shall also be installed in all the offices where interrogation and holding of accused takes place in the same manner as it would in a police station
  • CCTV systems that have to be installed must be equipped with night vision and must necessarily consist of audio as well as video footage.
  • In areas where there is either no electricity and/or internet, it shall be the duty of the States/Union Territories to provide the same as expeditiously as possible using any mode of providing electricity, including solar/wind power.
  • The internet systems should support clear image resolutions and audio.
  • CCTV camera footages should be preserved for a maximum possible period up to 18 months but not lesser than 12 months
  • An oversight mechanism should be created whereby an independent committee can study the CCTV camera footages and periodically publish a report of its observations thereon.
  • The District Level Oversight Committee shall have the following obligations:
    • Health Monitoring and reporting of the CCTV systems
    • To review footage stored from CCTVs in the various Police Stations to check for any human rights violation that may have occurred but are not reported
  • The Commission/Court can immediately summon CCTV camera footage in relation to the complaint of any incident for its safe keeping, which may then be made available to an investigation agency in order to further process the complaint made to it.
  • Posters at the entrance and inside of police station informing about the coverage of premises by CCTV, their privilege to file complaint to given authorities in case of any human rights violations inside the premises

The Government of Bihar has taken a huge step forward in its efforts to introduce transparency in the functioning of the police forces in the state. The Bihar State Electronics Development Corporation Ltd (BELTRON) has recently completed an ambitious project to bring the police stations of the state under 24×7 CCTV surveillance. More than 10,000 IP based CCTV cameras have been installed at over 900 police stations of Bihar. The project initiated and funded by the Home Department, Government of Bihar aims to fulfill the mandate of the Hon’ble Supreme Court to bring all police stations of the country under constant CCTV surveillance to protect human rights and prevent the use of torture in detention. The project was awarded to TATA Advanced Systems Ltd, one of India’s leading Physical & Cyber Security firms through a competitive bidding process at a cost of Rs 168 crores including operation and maintenance support for 5 years. Mr. C P Kariappa, Vice President, Tata Advanced Systems said “At TASL we have always taken pride in executing projects that build the nation, it was a prestigious project to be completed in challenging timeline across the state. Our teams could meet the expectations of customer despite disruptions due to flood and Covid-19”. The entire surveillance system is powered by Solar and online UPS to ensure 24X7 operations even if there is disruption in power supply. Mr. Kariappa further said “It was a pleasure working with Home Department, Govt of Bihar, Bihar Police and Beltron; this would not have been possible without their active participation and support. Also, we had an excellent team and partner ecosystem that lived up to all the challenges that was faced during the execution period”.

Bihar Government has plans to upgrade the existing system in line with the directions given by the Supreme Court and also extend it to the remaining police stations including outposts in the near future.

(2018) 5 SCC 311, directed that a Central Oversight Body be set up by the Ministry of Home Affairs to implement the plan of action with respect to the use of videography in the crime scene during the investigation. While considering the directions issued in D.K. Basu Vs. State of West Bengal & Others (2015) 8 SCC 744, it had held that there was a need for further directions that in every State an oversight mechanism be created whereby an independent committee can study the CCTV camera footages and periodically publish a report of its observations thereon. The COB was further directed to issue appropriate instructions in this regard at the earliest.

The Ministry of Home Affairs had constituted the Central Oversight Committee to oversee the implementation of the use of photography and videography in the crime scene by the State / Union Territory Government and other Central Agencies, to suggest the possibility of setting up a Central Server for implementation of videography, and to issue appropriate directions so as to ensure that use of videography becomes a reality in a phased manner.

The Court on 16/07/2020 had issued further notice to the MHA on the question of audio-video recordings of Section 161 CrPC statements as is provided by Section 161 (3) proviso, as well as the larger question as to installation of CCTV cameras in police stations generally. After which, action taken report was filed by 14 States till 24/11/2020, namely, West Bengal, Chhattisgarh, Tamil Nadu, Punjab, Nagaland, Karnataka, Tripura, Uttar Pradesh, Assam, Sikkim, Mizoram, Madhya Pradesh, Meghalaya, Manipur; and 2 Union Territories, namely, Andaman & Nicobar Islands and Puducherry.

The Court noted that the majority of the Compliance Affidavits and Action Taken Reports fail to disclose the exact position of CCTV cameras qua each Police Station. Further, it noted that the position qua constitution of Oversight Committees in accordance with the Order dated 03.04.2018, and/or details with respect to the Oversight Committees already constituted in the respective States and Union Territory have also not been disclosed.

Accordingly, the Supreme Court has passed the direction for filing of the Compliance affidavits by all the States and Union Territories by either the Principal Secretary of the State or the Secretary, Home Department of the States/Union Territories. “These affidavits are to be filed within a period of six weeks from today,” it said.

The Supreme Court has passed the slew of directions;

The Director General/Inspector General of Police of each State and Union Territory should issue directions to the person in charge of a Police Station to entrust the SHO of the concerned Police Station with the responsibility of assessing the working condition of the CCTV cameras installed in the police station and also to take corrective action to restore the functioning of all non-functional CCTV cameras. The SHO should also be made responsible for CCTV data maintenance, backup of data, fault rectification etc.

The State and Union Territory Governments should ensure that CCTV cameras are installed in each and every Police Station functioning in the respective State and/or Union Territory. Further, in order to ensure that no part of a Police Station is left uncovered, it is imperative to ensure that CCTV cameras are installed at all entry and exit points; main gate of the police station; all lock-ups; all corridors; lobby/the reception area; all verandas/outhouses, Inspector’s room; Sub-Inspector’s room; areas outside the lock-up room; station hall; in front of the police station compound; outside (not inside) washrooms/toilets; Duty Officer’s room; back part of the police station etc.

CCTV systems that have to be installed must be equipped with night vision and must necessarily consist of audio as well as video footage. In areas in which there is either no electricity and/or internet, it shall be the duty of the States/Union Territories to provide the same as expeditiously as possible using any mode of providing electricity, including solar/wind power. If the recording equipment, available in the market today, does not have the capacity to keep the recording for 18 months but for a lesser period of time, it shall be mandatory for all States, Union Territories and the Central Government to purchase one which allows storage for the maximum period possible, and, in any case, not below 1 year. It is also made clear that this will be reviewed by all the States so as to purchase equipment which is able to store the data for 18 months as soon as it is commercially available in the market. The affidavit of compliance to be filed by all States and Union Territories and Central Government shall clearly indicate that the best equipment available as of date has been purchased.

The Madhya Pradesh High Court while hearing a plea against alleged unlawful detention of the Petitioner by local Police authorities in the state, made prima facie observation that in order to escape liability, the Police often take a false stand that the CCTVs installed at Police station are not functioning. This Court feels prima facie that in order to cover up instances of unlawful detention by the police, the police comes up with the argument that the CCTV cameras are dysfunctional,” observed a Bench of Justice Atul Sreedharan.

It added that such a stand taken by the Police does not augur well for the ordinary citizens of the State as it creates an environment of giving an opportunity to the Police to act with impunity in complete disregard to human rights and personal liberty and enables them to detain anyone in the police station and conveniently give an explanation that the CCTV cameras were disfunctional during the period which the citizen says that he was unlaw detainer in the police station.

The remarks were made after the Court noted contradictions in the statements made by the local Police and by the Prosecutor, regarding reasons for not furnishing CCTV footage of the alleged date of detention. The former claimed that CCTV footage cannot be given as the cameras are not functioning since February 17. The prosecutor on the other hand submitted that the CCTV footage of the said period cannot be shown to the petitioner as that would reveal the identity of the source informant.

The facts of the petitioner’s case reveal a very shocking state of affairs in the State of Madhya Pradesh,” the Bench remarked while expressing surprise at the contrary stance. It noted that the prosecutor’s excuse for not giving the footage logically means that the CCTV cameras were functioning and there was indeed footage. But the police on the other hand claimed that the cameras themselves had turned dysfunctional from February, 2021.

In these circumstances, the Bench noted that the case discloses a larger issue and it has therefore summoned DIG- Bhopal (Urban), and SP (South Bhopal) on the next date of hearing, through video conferencing. They have been asked to come up with an explanation as to why the cameras were dysfunctional from 17.2.2021, whether the authorities who had to be informed about the dysfunctionality of the cameras were duly so informed by the SHO of PS Piplan, Bhopal and if they were so informed, what were the steps taken forthwith by those officials to have the cameras rectified in the shortest possible time.

Guide of IP Camera’s Footage Storage

Guide of IP Camera’s Footage Storage


If you are end-user then you may make question “if somebody destroy or theft my NVR/DVR then how we get video footage”. Question is very much true. Analog camera store / record there motion event on DVR & IP Camera store / record there NVR, some IP camera store limited data to there internal microSD card.
Or, Is there a camera that saves the footage on a host with FTP? Can I use my computer to store surveillance videos or footage? Are there any cameras that support cloud storage? Is there any camera that has a built-in memory card?

Or, you may say I am looking for a camera that can store up to a few days of data or a camera that uploads footage offsite or to a cloud or server.
How Can you Store Footage and Video Recordings
Generally speaking, you can store footage and recordings on an SD card, cloud, NVRs/DVRs, FTP or NAS. It comes down to what you are looking for. That being said , it’s still very important to weigh on differences and conveniences of each solution to narrow down growing pool of models available and find the best match.
·         Option 1. Micro SD Card
·         Option 2. NVRs/DVRs
·         Option 3. FTP Server
·         Option 4. Cloud-Based Storage
·         Option 5. Workstation Computer

Option 1. Micro SD Card

People will be opting for onboard SD storage when they are just looking for cameras that save motion-triggered footage or don’t want to subscribe to cloud service. For example, users said
“I want to store footage locally instead of uploading to a cloud or getting a DVR/NVR.”
“I intend to keep and save footage but don’t want to subscribe to a cloud service for storage. “
Or people who are looking for cameras that will be used in a location where internet access is limited but still want to store motion-based footage. For example, one user explained that
“I have a rural property and only have power at the house and barn. Best option would be a motion activated cam outside that I could attach to a tree. Wifi at my house is only available very close to the house and we are on satellite internet, so no real broadband for cloud solutions.”
The obvious benefit of storing via SD card is that it’s relatively safe and inaccessible by others, micro SD card storage option is extraordinarily popular with homeowners for surveillance on the front doorbackyardapartmentremote areasvacation home, oany place that doesn’t require constant 24/7 recording.

Option 2. NVR's/DVR's

Standalone NVRs and DVRs, as offsite storage solutions, are increasingly popular and widely used among home security systemsmall businessworkshop and etc.
If you are looking for a security system that can record video constantly and be able to save weeks of footages, standalone NVR's/DVR's with a built-in hard drive are what you need. For example, users expressed their needs, saying
“No need for motion activation but constant recording. And must have ability to review footage without needing to pause or stop recording”, “I need 30-day non-stop recording and want to record and save more than 3 cameras’ footages to a hard drive”
NVRs/DVRs are not just for storage, they are also embedded with the operating system to multi-task including managing multiple cameras simultaneously, motion-triggered recording & alarm, scheduling recording, 24/7 recording.
NVRs can also be accessed remotely from a Smartphone, tablet or personal computer.
One piece of advice after buying NVRs/DVRs would be keeping them safe from burglars orthieves as well as backing them up regularly to FTP server if needed.

Option 3. FTP Server

FTP server is a great footage storage option for those who have a reservation for cloud storage but don’t want local network drive or built-in memory card. For example, many homeowners expressed their thoughts on , saying
“I don’t want to go down the road of paying for monthly memberships to a cloud storage option for recording. I am looking for FTP or some other generic protocol method that is NOT a subscription based ‘cloud’ solution.”
Or
“I would like to save the footage on a host with FTP instead of storing the footage on a local network drive that could just be taken. or I have a FTP server and want to manage the footages or videos on FTP server, configuring security cameras to upload event-based recordings or snapshot or recorded images and videos to a FTP server.”
FTP server is, without any doubt, a good solution. Security cameras such as Reolink cameras are proving to be increasingly popular with homeowners. Many Reolink security cameras do support FTP storage, both motion-based footage and constant video recordings.

Option 4. Cloud-Based Storage

Cloud-based storage is gaining popularity among users who are looking for an alternative to NVR/DVR, SD card, and NAS and there are growing numbers of cloud-based video surveillance cameras and IP camera with cloud storage available on the market.
Cloud-based storage is relatively convenient and safer; however, cloud services are commonly charged and require a varied monthly subscription fee.
Cloud-based storage is also potentially putting a strain on the home network by putting pressure on network bandwidth, as well as compromising photo or video quality to achieve optimal performance.

Option 5. Workstation Computer

Of course, you can always turn your personal computer into a storage unit by configuring storage path to your computer; however, massive data storage could slow your computer down and eat up storage space rapidly.
Not only that, CCTV forage auditing you can do from computer. You need window license based software only. That software takes screenshot of your open Camera Viewing window. In this scenario you can see what camera saw. Camera see 24Hr, you are able to see within 24min, I am confirm your DVR / NVR can’t do it. ‘Auditing’ means 'seeing' what the cameras 'saw'. CCTV video footage should be audited daily; several times a day if need be. Depending on the requirements, auditing of CCTV footage of critical cameras on a daily basis must become an SOP. Auditing will help relevant stakeholders to ‘discover’ the 'unknown'. Auditing as an activity may be manual, it may be post-facto, but it is a very dedicated and systematic process, which helps address some of the challenges of live monitoring (video blindness, poor attention span, boredom, bias, fatigue etc.), as well as the challenges related to alert-based systems (how often has one faced false alerts, or what is called the ‘cry-wolf’ effect). Auditing will help discover issues as mentioned above as well as in identifying and analysing threats and hazards (THIRA/HIRA) of various kinds. Auditing CCTV video footage will also be extremely helpful in waste reduction and following the 5S philosophy, i.e. sort, set, shine, standardize and sustain (all part of Six Sigma practices).  Moreover, in case of an accident/incident, relevant authorities can analyse CCTV video footage to determine whether implementing or improving existing policies, procedures, and processes could help reduce the potential for future occurrences.
And you can transfer those recordings from your computer to hard drive, pen drive, USB and etc accordingly.

The Tradeoff

There’s no right answer here. It’s really a matter of preference and there are plenty of models out there to suit either taste. Understanding each footage storage option will help you narrow down the growing pool of models available today and it will help you understand the features that matter to you most. Camera saw everything, but we can’t see what camera saw.

Media Converter best for Surveillance Network

Media Converter best for Surveillance Network

Over the years, there has been a growing popularity of Video based Ethernet networks, resulting in the increasing use of Ethernet switches in the video network infrastructure.
Many types of video security and surveillance networks that are designed for applications in different environments. Analog video network and IP video network are the two most commonly used types for security and surveillance video transmission.

While IP video is more advance and can provide better image quality and network performance in large scale. The biggest character of IP video surveillance network is that every camera has its own IP address to tell itself from the others in the whole video network. Currently, with the demand for higher transmission speed, image quality and longer transmission distances, fiber optic cables are widely used in the video network. Thus, in both of the two surveillance networks, media conversion are necessary, like conversions between fiber and copper or video to fiber. The following will offer the cabling solutions that using media converters.

Video Media converter is a simple networking device that enables you to interconnect networks or network devices with different speeds, operation types, modes and media types. And the most common type usually works as a transceiver, converting the electrical signals in copper unshielded twisted pair (UTP) network cabling to light waves used for fiber optic cabling. It is essential to have the fiber optic connectivity if the distance between two network devices is greater than the copper cabling's transmission distance. Since media converters are IEEE compliant devices, they implement IEEE data encoding rules.
What is the

SFP module?
The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA).

Media converter?
A fiber media converter is a simple networking device that make it possible to connect two dissimilar media types such as twisted pair with fiber optic cabling. Twisted pair cable, coaxial cable and other copper cabling can only support limited length before signal becomes too weak. Main application area is in security surveillance.

Why Best:

Ease of Use and High Availability
The SFP ports are widely used in the Gigabit Ethernet and the Fiber channel to provide a flexible and cost-saving solution for the enterprise networks and data centers. SFP port available in Enterprise Gigabit Ethernet Switcher. During the troubleshooting entire network will be down for time being.

Configuring and installing redundant solution of media converter is much easier to handle and to manage than higher-layer devices. And it will makes the troubleshooting easier if you add management functions to the media converter.
Proprietary
SFP modules are vendor dependent and switch is not available or that part number switch manufacture is stopped. In that case whole network switches needs to be stopped.

Media Converter is available, it can change any time. Its biggest advantage of this product.

EMI Emissions
The heat and EMI emissions are one of the biggest problems related to SFP devices.
No Such pain with media Converter.

Flexibility and Simplification
Wonderfull performance with LAN without protocol transparency with 850 nm and 1300 nm multimode fiber and 1310 nm and 1550 nm single-mode fiber.
It is of much flexibility for media converter to combine copper with 850 nm and 1300 nm multimode fiber and 1310 nm and 1550 nm single-mode fiber. With protocol transparency, it can be applied in anywhere in the local network or remote network whether it's a LAN, WAN or the MAN environment.

Handling Warning
Copper SFP are static sensitive. To prevent damage from electrostatic discharge (ESD), it is recommended to attach an ESD preventative wrist strap to your wrist and to a bare metal surface whenever you install or remove a Copper SFP module.
No such warning with media converter.

Safety Warning
Only trained and qualified personnel should be permitted to install or replace.
No such personnel required.

Spaceing
SFP Module takes up less space at Network Switch port.
Media converter  takes Little more space.

Powering
SFP Module Take power from Enterprise Ethernet Switch.
Media converter derives power from the switch it's plugged into. (Media converter requires a separate AC power outlet.)

Cost Reduction
Compared with the hybrid media switches, the cost of media converters with cost-effective Ethernet switches is much lower. This type of media converter solution can cost significantly less than that relies on higher-layer devices such as routers or switches.

Biggest advantage in this type of topology is where network consist of more than hundred nodes network. Fault point is reducing to switch only.

Analog Video Network Cabling Infrastructure
In a typical analog video network (shown in the above picture), analog CCTV cameras are connected to a central management room or devices (VCR—video cassette recorder or DVR—digital video recorder) via coaxial cables. If the camera has PTZ (Pan-Tilt-Zoom) function, an additional controller is added.

As mentioned, the performance and the transmission distance are limited by using copper cables. To connector more fixed analog cameras and PTZ analog cameras, fiber optic cable should be introduced to this typical network. Then fiber media converters are the best solutions. The following picture shows the basic structure or an upgraded version of a typical analog video structure which using fiber optic cable in this network.
To connect the fixed analog cameras to the server room, a pair of fiber media converters should be added between the server room and cameras. Video signals will be transmitted into fiber optic signals. For analog PTZ cameras, there are two types of signals should be converted into fiber optic signals, one for video and one for data. Thus, two different media converters or a fiber media converter that covers the two functions should be installed.
It is known that fiber media converters should be used in pairs. As one of the media converters is in deploy on the fiber end that near the camera, the other one should be deploy on the other fiber ends that near the server room. For better management, all the fiber media converters at the fiber end near the server room could be installed in a managed fiber media converter rack chassis.
IP Video Network Cabling Infrastructure
In a typical IP video surveillance network (shown in the above picture), IP cameras are connected directly to the local area network and transport video across the IP network via UTP cabling and switches. PoE IP cameras are also time-save and cost-effect solutions. Video can be recorded to any PC or server on the network. To introduce fiber optic cabling in to this typical IP video network, the method is similar to introducing fiber optic into an analog video network as described in the above paragraph.

In the following case (shown in the following picture), PoE IP cameras are used. A pair of PoE media converters should be installed on both ends of a length of fiber optic cable to achieve the conversion between video and fiber. At the computer side where the videos are recorded, a pair of Ethernet media converters should be installed. All of the media converters near the network switches can be set at a managed media converter chassis before the connected to the switches.

Difference between Dynamic and Static IP

Difference between Dynamic and Static IP
The major difference between dynamic and static IP is that dynamic IPs change every time one connects to the internet, while static IPs remain the same.
Internet Protocols, also known as IP addresses is a 32-bit number that is usually assigned to a computer when it connected to a network, such as the Internet. The IP address works similar to an actual address and lets computers know where to send data packets. The network devices use these address in order to communicate with each other.
The IP address are made up of 4 parts of numbers that are divided by dots (.) So, a typical IP address will looking something like – 72.169.189.01.
Although, the IP Based product / computers communicate with each other using IP addresses, to make it easier to remember the internet uses DNS or Domain Name System. This DNS is sort of an address book that pairs names to IP addresses. For example, if one wanted to visit the Google website, they would type in www.google.com in the address bar. The DNS will look up the IP address (74.125.239.35) paired with this name and will ping that address. Their system will respond back and the webpage will load on your computer.
There are two types of IPs – dynamic and static IP addresses. The major difference between dynamic and static IP is that dynamic IPs change every time one connects to the internet, while static IPs remain the same.
There are limited amount of IP addresses that are available and for this reason, many companies assign dynamic IPs, unless a static IP is asked for. So, every time a device is connected to the Internet, the IP address can change. This also allows the limited number of IPs to become reused, making it more convenient.
Broadband connections today lease IP addresses and use the DCHP dynamic IP address system. This system is also often considered safer, since the IP is always changing it makes it more difficult to hack the computer. Static IPs are commonly used by companies or people who require a similar IP address. The can apply for a static IP by paying a fee.
