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) compliance. The 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 enabled, that 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.

Security Camera Input Setup

 Security Camera Input Setup

Artificial Intelligence (AI) security cameras are specialized network IP cameras that perform advanced analytical functions such as vehicle detection, person detection, face detection, traffic counting, people counting, and license plate recognition (LPR). These artificial intelligence functions are achieved using highly advanced video analytics software that is built-in to the camera and recorder they are connected to. AI cameras can be used as a stand-alone device by recording to an SD card, or they can be connected to a network video recorder (NVR) to create a multi-camera AI system that records to a central hard drive. Please note that only certain models are capable of license plate recognition / automated number plate recognition (ANPR).

A special characteristic some network video devices possess is an integrated input & output ports. This incorporation allows for the communication and interaction of external devices, such as but not limited to:

1.   Doorbells

2.   Switches

3.   Alarm System Relay

4.   Pressure strips

5.   Detectors (frequency, smoke, movement, sound, temperature, and humidity sensors)

All these functions can be achieved via:
1.   NVR/DVR (remote or local)
2.   Application through a smart device (Tablet or Phone)
3.   Computer (local or remote / software or browser)

 

Camera / DVR / NVR Alarm Input

Motion sensors / motion detectors can be integrated with video surveillance systems to provide additional security for buildings and also outdoor areas. For example, a PIR sensor (passive infrared) can be connected to the alarm input of a security camera DVR or IP camera NVR to trigger video recording and send an alert to the property owner that motion has been detected in a certain area.

When motion is detected by the motion sensor, it triggers the following alarm actions.
1.   Trigger video recording on the camera associated with the alarm.
2.   Enable the alarm output on channel one, where I have an alarm light attached (turn the strobe light on).
3.   Pop-up live video of the camera associated with the alarm on the DVR’s display monitor.

Here are some additional actions that can be triggered from an alarm input.
1.   Capture a still image snapshot.
2.   Send a push notification to the mobile app for iPhone & Android.
3.   Enable the alarm buzzer on the DVR / NVR.
4.   Send an email notification.

The inputs and outputs can be used to eliminate unnecessary recording of video or coincide with your alarm system to systematically create a reliable and accountable security source. When input and output mechanisms are triggered, you can (manually or automatically) request through the network video device that certain actions be performed over the network as well as trigger devices attached to the output ports. Example:

This example picture above shows a person interrupting a sensors function. This creates a signal that travels to the camera and the camera computes the message. The camera then functions as programmed and starts recording (snapshots or footage) to the delegated device while simultaneously triggers a relay to close. When the relay closes, it completes the circuit for the siren or strobe to activate. Another configuration (as long as the cameras capable), have the camera record to the desired method based on motion and simultaneously trigger the relay to set off the siren. In this example, a motion sensor is taken out of the equation.

Again, the above picture shows only one of many configurations. You can configure in whatever method you desire. Including or excluding recording methods based off of:

·        Motion (movement takes place)

·        Masking (the camera has been covered or obstructed significantly)

·        Video Loss (picture is no longer materializing, this feature is more prone to function correctly via a recorder or program)

Other devices that can be attached and configured to your I/O ports are as follows:

Device Type	Description	Occurrence of activation
Entry Contacts	Simple magnetic sensors detecting opening of doors, windows, gates and shutters.	When the circuit is broken (door is opened) the camera can record and/or send a snapshot and notifications
Motion Sensors	A sensor that detects motion either based on heat, light, or frequency	When motion is detected, the sensor breaks the circuit and  the camera can record and/or send a snapshot and notifications
Glass Break or Glass Shock Sensor	A sensor capable of distinguishing the sound/vibration of breaking glass and/or splintering wood.	When glass is  disturbed or shattered, the glass sensor breaks the circuit and the camera can record and/or send a snapshot and notifications
Pressure strip or switch	A pressure or switch sensor that are needed to interact with before gaining entry or exiting a premise or structure	When the sensor is triggered it breaks the circuit and the camera can record and/or send a snapshot and notifications

How-to Install Motion Detectors with a Security Camera System

Installing a motion detector and integrating it with a security camera system is fairly simple. CCTV Camera Pros supports professional and DIY installers. Most PIR motion sensors are 12V DC powered which gives installers the choice of using a individual 12V DC power supply or one of the ports on a multi-channel power supply box (the same ones used with security cameras).

In this first diagram, a single 12V DC power transformer is used. This is how it works.

1.   On the right side of the diagram, the alarm input / output panel of the DVR is shown. This is what the alarm panel on the back.

2.   18/2 gauge power cable connects the output of the motion detector to one of the alarm input ports on the DVR.

3.   18/2 gauge power cable is also used to connect the motion detector to an individual DC power supply.

4.   A PT-4 power lead connects the raw cables to the 3.1mm plug on the power supply.

Installation with Power Supply Box

A multi-channel power supply box can be used instead of an individual power supply.

This installation is the same as the one above using the single power supply. The only difference is the use of a multi-channel power supply box to power the motion detector. CCTV Camera Pros supplies many of these power boxes for security camera installations. These power boxes can be shared with cameras and 12V DC powered alarm sensors. Because power supply boxes use screw based wire terminals, there is no need to use a PT-4 power lead (as with the individual power supply installation). Same connection for Camera & NVR.

Most of Camera PIR motion sensor is located on the front of the camera, just below the camera lens. This motion sensor is designed to detect movement of human sized objects when they come into view of the camera’s lens. The camera has a 2.8-12mm varifocal lens which when adjusted to the widest angle (the 2.8mm setting) the camera provides a 109 degree horizontal field of view. The PIR sensor detects motion across a 100 degree field of view. Please note that if you adjust the lens to a more narrow field of view, this does not effect the area where the PIR sensor will detect motion.

In my experience, using a PIR sensor based motion detection is much more reliable than software based video motion detection (especially for outdoor video surveillance). Typically there are a lot of small moving objects outdoors which makes it difficult to get the sensitivity just right. When security cameras turn to night mode, there is typically some video noise because of the lack of light. This noise can cause false alarms when using video motion detection. A PIR sensor uses infrared light to measure the radiation reflected by objects in its view. When a certain amount of this radiation changes, the PIR sensor triggers an alarm, so they are not susceptible to some of the challenges of outdoor video motion detection.

FAQ

Here are some frequently asked questions about integrating PIR motion detectors with security camera systems.

·        How are motion detectors used with security camera systems?
The most common way to integrate a motion detector with a security camera system is to hard wire the motion detector to the same surveillance DVR that your security cameras are connected to. You must make sure that your DVR that has alarm inputs.

·        Can I just use motion detected from my security camera instead of an external motion sensor?
Yes, most DVRs support video motion detection triggered by cameras. Please note that this is different from PIR (passive infrared) motion detection and can be less reliable. Video motion detection tends to produce more false positives than PIR motion detection, especially in outdoor and infrared camera applications. This is because the video tends to be more noisy and outdoor environments tend to always have some motion from wind and other natural elements.

·        What type of cable is used to wire motion detectors to DVRs?
The following types of cable can be used to wire motion detectors: CAT-5 cable (one pair), 18/2 conductor power cable.

·        Do motion detectors require power?
Yes. Most PIR motion detectors use 12V DC power. All of ours include the proper power supply with them.

·        Can I use multiple motion detectors with my surveillance system?
Yes, as long as your DVR has multiple alarm input ports, you can use multiple motion detectors. Different model DVRs support different numbers of alarm inputs so consult the specification or contact us if you need help.

Not every camera or NVR/DVR possesses this unique features or can be operated through the above mentioned methods. Be sure you research everything you will need to make this type of setup successfully work for you. This includes the correct relays, power supplies, capable camera and recording devices. Most our IP mega pixel cameras and recorders have the capability of all previous mention features above.

AI Based Camera Output Triggers Strobe Light

AI Based Camera Output Triggers Strobe Light 

Artificial Intelligence (AI) security cameras are specialized network IP cameras that perform advanced analytical functions such as vehicle detection, person detection, face detection, traffic counting, people counting, and license plate recognition (LPR). These artificial intelligence functions are achieved using highly advanced video analytics software that is built-in to the camera and recorder they are connected to. AI cameras can be used as a stand-alone device by recording to an SD card, or they can be connected to a network video recorder (NVR) to create a multi-camera AI system that records to a central hard drive. Please note that only certain models are capable of license plate recognition / automated number plate recognition (ANPR).

 

DVR / NVR Alarm Relay Output

Please note that the the alarm strobe light is self-powered. The alarm outputs on the DVR / NVR are simple relays (they are either open or closed). They DO NOT provide any power output. Also, please note that you can ONLY connect low voltage devices alarm devices to these alarm relay ports. Connecting high powered devices can fry your motherboard and ruin your DVR / NVR.

Important WARNING! The maximum current rating of these alarm relays is 1A, the voltage is 30VDC/ 250VAC, so the maximum power rating is 30W for DC alarm device, 250W for AC alarm device.

You can see above how I wired the strobe light to the output port. Notice how the strobe light’s 12V DC power supply is connected in-line. I used 18 gauge 2 conductor PVC Insulation Jacket Unsheilded / Stranded Copper wire to connect the strobe light to the recorder.

Here is a close-up of the alarm output ports on the back of the DVR / NVR. I am using the COM1 and NO1 ports. NO stands for normally open, which means that power does not flow thorough the relay until the alarm is triggered.

AI Software Setup

Please follow these steps to configure the AI software on the NVR.

From the DVR/ NVR main menu, select AI / Event.

On the AI / Event screen, do the following.

1.   Select More from the AI Event menu.

2.   Select the camera that you are applying the AI rule to from the camera dropdown.

3.   Select Line Crossing as the event type.

Next, do the following.

1.   Check the Enable Detection by IPC (IP Camera) checkbox.

2.   Check the Draw Line checkbox and draw your tripwire on the screen.

3.   Choose the direction of the traffic flow used to trigger the alarm. You can choose a single direction or both directions.

Next.

1.   Click on the Detection Target tab.

2.   Check Human for the detection target type. Uncheck Motor Vehicle and Non-motor Vehicle as they are not applicable in this case.

1.   Click on the Trigger Mode tab.

2.   Click on the Alarm Out Configure button. Please note that you may setup additional alarm triggers on this screen such as image snapshot, mobile app push notification, alarm buzzer, pop-up video, and email alerts.

On the DVR alarm output screen, select the alarm output that your light (or other device) is connected to from the window on the left and click on the arrows (>>) to put the alarm output on the right window. Then, check the checkbox next to it.

Click OK. Then, click Apply in the lower right.

You may then close all of the DVR / NVR configurations screens and return to the live view of your security cameras.

AI Software / Object Detection Visualization

On the live security camera view of your recorder, double click on the camera that you are using for this alarm project to show that camera’s live view full screen. You can enable the AI / Object Visualizations by clicking on the above icon.

 

When you enable the AI software visualizations on the live camera view, a few things happen.

1.   The alarm event window opens on the right. When your security camera detects the event that you configured, a snapshot image will appear in that screen to document the event.

2.   All objects that the system is able to detect will be outlined. Please note above that I am outlined with that yellow box because the AI software is detecting me as a human. The cars in the background are outlined in purple. Even though we are only using people detection for our alarm, the NVR software still outlines the other object types that it recognizes.

3.   The line crossing / virtual trip wire is shows in red. And the A->B traffic flow that I setup it also shown

4.   NVR / DVR Alarm Output Turns Light On

Last, here is a screenshot of the strobe light turned on as a result of the human detection / line crossing event.
