Security Cameras in Medical Collage

 Security Cameras in Medical Collage

CCTV surveillance is now an integral part of the overall security apparatus across the world. The university has a significant responsibility to take appropriate steps to protect personal privacy and civil liberties when it operates security camera systems. When successfully deployed, security camera systems enhance overall campus safety and security, deter crime, and otherwise support the protection of people and property. A security camera is defined as video surveillance technology that records people’s activities in order to detect, deter, prevent, or investigate crime or other threats to public safety.

In a bid to improve the quality of medical education in the country, regulatory body NMC has issued an advisory recommending installation of cameras in the premises of all medical colleges and institutions. This is in continuation of the digital mission mode project being run by the National Medical Commission (NMC) and the erstwhile Medical Council of India to ensure and monitor availability of adequate number of patients teaching faculty and also to monitor regular teaching programs in the medical colleges. This is a step forward towards developing a robust monitoring mechanism and providing for transparency and accountability in functioning of medical colleges, official sources said.

If utilised properly, this would also be a way forward for digitisation of the assessment process for approvals being granted to medical colleges either for enhancement of under graduate courses or starting or enhancement of postgraduate courses, they said. "Use of such technology and artificial intelligence would make assessments and instructions transparent and an ongoing process instead of the current one time process," an official source said.

The most important things they can incorporate on all IP equipment are much more tangible—Trusted Platform Module (TPM) and National Defense Authorization Act (NDAA) complianceThe primary concern should be that the vendor is providing a system that is secure and in compliance with ISO 20243, particularly when it comes to assurances regarding the supply chain. Today more than ever, it is essential that video appliances are held to an IT standard, including TPM and NDAA compliance. The importance of making these properties a top priority has become a standard for end-customer expectations.
But installing a CCTV camera doesn’t mean you’re safe; here is a list of seven things you ought to consider before securing your territory with closed-circuit television cameras:

#1) Deciding how you’ll be monitoring the system

If you decide to monitor your system using the Internet, getting an IP Address for your Digital Video Recorder (DVR) or Network Video Recorder (NVR) will equip it to survey and record easily; an Ethernet cable carries all information via the Ethernet witch.

#2) Determining the number of Closed Circuit Television Cameras required

Depending upon the nature of your requirement and the expanse of the area you want to survey, decide on the number of cameras required to ensure complete security. As per the NMC guidelines, the medical colleges have been advised to install cameras at OPDs (depending upon number of OPDs in the college). The cameras should cover the medicine, surgical, gynaecological, paediatrics and orthopaedics OPDs, the highly-visited OPDs in a medical institution.

#3) Positioning the CCTV cameras

Cameras if visible could caution the trespasser. Thus most people prefer having clandestine cameras to having exposed and evident ones! Contemporary CCTV cameras can be easily hidden from view by being in the most exquisite of crevices and clefts in the wall; these places also offer the advantage of protecting the cameras from extreme weather conditions such as hailstorms, high-speed winds, and rains. One camera needs to be installed at the main entrance of the hospital and college and two cameras at the patient registration counter. All lecture theatres in the medical college should be equipped with cameras.

The pre-anaesthesia area, recovery area in the operation theatre complex, faculty lounge and attendance marking areas, anatomy dissection hall, physiology laboratory, biochemistry UG laboratories, pharmacology laboratory, patient attendant waiting area and emergency and casualty ward need to be equipped with cameras, the NMC stated.

#4) Placing the DVR/NVR

It is paramount to secure the digital video recorder (DVR) or the network video recorder (NVR). If you lose the DVR or the NVR to the trespasser, needless to say, you lose all the money you spent on your CCTV camera along with your stolen valuables! If you place your DVR or NVR centrally, you can minimize your cabling cost and reduce the complexity of your closed-circuit television system.

#5) Deciding on power backup of CCTV Camera

The constant power supply would ensure incessant surveillance. Thus make sure you have both constant power supply and a reliable power backup in case of power cuts to ensure security at all times.

#6) Deciding how you’ll be create Secure Network system

NDAA compliance assures that the video recording appliance does not include System on Chip (SoC) or other components capable of processing software from banned Chinese companies. All servers and workstations use NDAA-compliant chipsets as a standard. Having the NDAA seal of approval guarantees that the product is fully supported under those regulations as federal agencies have banned all non-compliant equipment from RFQ’s and projects. Those companies not adhering to NDAA standards are unable to work with any federal organization via a published blacklist. Business and commercial entities are also following suit, as they have privacy concerns consistent with the federal government as well.

Trusted Platform Module enhances computer privacy and security. Consider it a hardware-level security measurement to protect your video recording device from malicious attacks. Once the TPM module is enabledthat physical chip is now permanently tied to that specific server or workstation and cannot be moved to any other system. TPM-based microchips on system boards offer another layer of hardware and intrusion security.

This software agnostic TPM module is utilized for high-level security file encryption, network security, and password management. These modules are secured by cryptographic algorithms and ensure total system security for the most sensitive data on your video recording system. As a matter of fact, TPM modules are a standard requirement from every video management software manufacturer and independent software vendor in the security marketplace.

#7) Testing the CCTV Camera system

After you’re done with the installation process, it is very important to have a test run. Any problems that you might face with your closed-circuit television system, can be best fixed before it’s too late – a stitch in time, does save nine!

#8) Maintaining the CCTV-cameras

Best practices include cleaning the cameras on a monthly basis to rid them of any dirt, cobwebs. Timely replacement of the cables used is also advised to keep the systems from any potential failures in the most crucial of hours.

#9) "Cameras never lie". But how will one know, unless one 'sees' what the camera 'saw'?

Encourages all medical collage authority of CCTV to audit their own CCTV video footage as a standard operating procedure. Regular auditing of CCTV footage by the public means that the Police/LEA have more 'eyes' working for them through crowdsourced surveillance. This enables the Police/LEA in identifying potential threats and dangerous situations before they occur. Also, in the case of a crime, if a standardized incident report is delivered to the Police/LEA by the affected party in PowerPoint carrying the entire story (what, where, when, why, who, how, and the video clip), crime will get solved faster.

The aim is to bring the colleges under the National Medical Commission’s surveillance, protect doctors from any attack during duty hours. There are a lot of brands in the market selling closed-circuit television cameras. The best brands include Infinova, Hanwha Techwin, Avigillon, Pelco, Axis, NUUO, Milestone and GVD etc Solution for reliable CCTV cameras. To get free consultation contact us.

Common Problems and Solution for IP Cameras

IP camera or network camera is a new product which combined with analog and network video streaming technologies, in addition to its image capturing functions like the conventional analog camera, IP camera has built-in video compression processor with web server function, to compress raw video footage, then broadcast over Internet. The authorized users can access the data from anywhere with internet connection. 
What's the common problem of IP camera?

1. Can't find IP camera when you use search software

Foremost, rechecking whether power supply and Ethernet cables are connected correctly. If the problem still exists, checking the network setting for IP camera and your computer/Laptop/tester. Go to network connection, configure IP address to same IP segments, Subnet mask and default gateway must be same for both IP camera and computer. Ensuring IP camera and computer are in the same router.

2. Can't visit IP camera from Internet (WAN)

For this problem, there are two possible factors. Firstly, there is no port mapping for IP camera. As we know, IP camera requires port mapping for remotely access from Internet (WAN). Without port mapping, IP camera is only accessible from local network (e.g 192.168.1.20). To solve this problem, you just need to log in your local router, and enable port mapping for IP camera in virtual server menu. Secondly, if you use domain or DDNS service, making sure the domain point to correct IP address with correct port number.

3. Connect 4 IP cameras, but only one IP camera displays images

This problem occurs when you didn't change the default IP address of IP cameras. After you bought the IP cameras, all of them were configured with a same IP address. With reason of IP conflict, when several IP cameras connect to router, one camera can work, but the rest of cameras can't connect to network. To solve this problem, you need to set an unique IP address for each of cameras.

How to change IP address for the IP Camera ?

Accessing the camera with default IP address (e.g 192.168.1.20), then login with default account information. Go to "Device Config", then choose "Network", you can change the IP address for the camera.

4. PoE IP camera can't see at night (dark images)

Insufficient power supply, which caused the PoE IP camera can't turn on Infrared illuminators, thus images are black at night. PoE (Power over Ethernet) is useful technology which greatly reduced the cost on IP camera installation. But it also has drawbacks; the voltage will drop when PoE IP camera connects to a PoE Switch or NVR. Typically, IEEE802.3af standard PoE only can transmit 20-30 meters. To solve this, user should use high quality Ethernet cable, or shortening the connection distance.

5. Video delay (video latency) when watch live video

Since network camera need to compress the video, before broadcast over Internet, every IP cameras encounter video latency, which is a common problem in IP video surveillance system. To minimize the video latency time, you can increase the bandwidth through upgrading your network infrastructure, also you can lower the bit-rate of streaming. Lowering the image resolution also helps to reduce the video delay time. Increasing the fps can allow IP camera output smooth video.
Do you experience any of these problems? Please make comments if these information is useful to you. If you experienced other problems which are related to IP camera, please write it down in below comment section.

6. IP camera can't display images

If your IP camera can't display images, also you are not be able to access the IP camera, likely the IP camera doesn't boot correctly. Almost IP cameras work with DC12V power supply, power requirements are different. You can estimate the power requirements on the basis of IR range.
·        No IR, or IR range within 20 meters: Required Power Supply DC12V 1A
·        IR range is within 20-30 meters: Required Power supply DC12V 1A
·        IR range is within 30-50 meters: Required Power Supply DC12V 1.5A

Please note: A regular PoE switch, supports IEEE802.3af, this standard only provides maximum 15.4W power, which means the provided current is 1.25 ampere. In conclusion, the regular PoE switch only can work with IP cameras which require no more than 15.4W power.

7. How to upgrade NVR firmware

If your IP camera connects to NVR, not all problems are caused by IP camera. Sometimes, the problem was caused by NVR. You may solve the problem through upgrading or updating NVR's firmware.
To update the firmware, you need to get the firmware file in a USB stick, which then has to connect USB port of NVR for upgrading.
Step 1. Go to "System Setting", choose "System" > "Upgrade"
Step 2. Select the firmware file, then click "Upgrade".
Step 3. When upgrading succeed, the NVR will reboot.

8. NVR can find IP camera but can't display image

If IP camera can be found through automatically search on NVR, this means the IP camera works properly, NVR detected and received correct video streaming parameters from IP camera. If your NVR shows video abnormal, you need to check the video resolution setting for both IP camera and NVR. The video resolution should be same as the NVR's recording resolution. If you use our IP camera and NVR, you need to choose the system's recording resolution as in below picture:
Choosing appropriate main stream and sub-stream resolution
