CCTV stands for closed-circuit television and is commonly known as video surveillance. “Closed-circuit” means broadcasts are usually transmitted to a limited (closed) number of monitors, unlike “regular” TV, which is broadcast to the public at large. CCTV networks are commonly used to detect and deter criminal activities, and record traffic infractions, but they have other uses.

CCTV Cameras

How Does Cctv Work
Analog and digital systems work quite differently but modern CCTV networks use conversion software and hardware to convert analog to digital.
A sequence of images is picked up on by the camera, which is transmitted as a signal that passes on to recording device and display device. The camera itself captures the video source.
Analog
Digital (IP)
A traditional CCTV system comprises:
One or more cameras (analog or digital), each with a lens equipped with an image sensor
A recorder – Either a standard video tape recorder for analog systems, or a Direct Video Recorder (DVR) or Network Video Recorder (NVR) for digital systems
Cables – Either RJ45 for digital or coaxial for analog
One or more monitors to which the images are transmitted
Analog Security Systems
Analog surveillance systems work by connecting your standard analog camera to a digital video recorder (DVR) via transmission cables. The DVR receives the video from the camera, compresses it, and then stores it on a hard drive for either live viewing or later viewing.
IP CCTV camera system
An Internet Protocol camera, or IP camera, is a type of digital video camera that receives control data and sends image data via an IP network. They are commonly used for surveillance but unlike analog closed-circuit television (CCTV) cameras, they require no local recording device, only a local area network

![cctv]()
-
A camera records images through the lens using image sensors.
-
These images (and often audio too) are transmitted to the recorder or tape, either wirelessly or by cable. Recorders may use analytical software and other smart technologies to scan the data and send automated alerts to either humans, or other systems and devices. This Video Management Software (VMS) records, stores and analyzes video feeds. The software is often self-learning, using machine learning (ML) algorithms that utilize functionality like motion detection, face recognition, people counting, etc.
-
Monitor(s) can be passively (through software) or actively (by people) monitored. CCTV networks can, and should, themselves be monitored.
-
Analog - Use Bayonet Neill-Concelman (BNC) connectors on coaxial cables to transmit continuous video signals. They are relatively low resolution but cheap and effective. There are more peripherals in an analog system, e.g. standard coaxial cables don’t usually transmit audio. Analog signals can be digitized, making it more cost-effective to go digital even with older equipment. The images require a video capture card and can be stored on a PC or tape recorder.
-
A step up, analog HD enables increased resolution over traditional systems (1080 pixels) and are backwards compatible with analog cameras and BNC.
-
Digital – Digitalize signals at camera level. These systems don’t require a video capture card as images are stored directly to a computer but require a (relatively) large amount of space to store recordings, so they are usually heavily compressed.
-
Network or IP – Used with analog or digital cameras, these systems utilize a video server to stream footage over the internet. The advantages are the possibility of Wi-Fi and audio, Distributed Artificial Intelligence (DAI) for analyzing image footage, remote access, Power over Ethernet (POE), and better resolution. Furthermore, IP cameras have the ability to contain more cameras in one, which can cover a wide angle that may normally take multiple cameras or camera systems to cover. All three options are still equally in use, with a high tendency to IP camera systems and digital video cameras.
DVR (DIGITAL VIDEO RECORDER)

DVR Recording & CCTV Video Management
DVRs make it possible for users to convert analog CCTV video to digital, allowing for remote monitoring, greater storage capacity, and quick and easy searches. Think of the DVR as a cost-effective solution for those not yet ready to move to a full-on IP surveillance setup. Digital video recorders allow you to bring your analog CCTV cameras into the modern age. When footage is converted to digital, new worlds open up in terms of how you can view and manage your video feeds.
It wasn't long ago that most surveillance systems used VCRs to record individual video streams. The footage was recorded either continuously or triggered by an event, and recorded on cassette tape usually at a rate of 25 frames per second. Back in the day, this seemed like an advanced solution. But now we know, regardless of what type of surveillance cameras you're using, storing video footage on cassette tapes is not a very effective strategy. The tapes take up space, can't hold very much information, and they're incredibly difficult to search through if you need to pinpoint video images of a specific event. Enter the digital video recorder (DVR).
Recorders
DVRs are usually part of the CCTV system, connecting to various internal components, not to external networks. DVRs are generally used with analog cameras. In a DVR system, every camera must be connected directly to the recorder.
While DVR systems process footage themselves, NVR systems encode and process data at the camera level, and then stream it to the recorder, which, in turn, is used for storage and remote monitoring. NVR systems usually use IP cameras. In an NVR system, each IP camera connects to the same network.
CCTV Back Up Footage Playback Checking Method
![cctv]()
HARD DISK (STORAGE) Monitoring CCTV networks
![cctv]()
One of the fastest growing trends in CCTV security, network monitoring software ensures CCTV systems stay up and running, and can provide 24/7 monitoring of an area and reliable notifications. Monitoring systems can alert staff when there is a power failure (and automatically switch to a backup power supply), constantly check for unusual activity on the network, and be configured for different types of usage, risks, and requirements
Digital Storage
Not long ago, most surveillance systems could only record to VHS cassette tape. Recording to tape has many drawbacks. For one, the tapes are bulky and take up a lot of space. Additionally, trying to search the recorded footage on analog tape can be a time-wasting nightmare. With DVRs, your footage is converted from analog to digital, so you can store significantly more video without the clutter, and it's much faster and easier to sort through archived footage.
Video Compression
To make the most of available storage capacity, DVRs provide a number of different compression technologies. Common compression formats include Motion JPEG, MPEG-4, and H.264. With video compression, your files sizes are reduced as much as possible without compromising image quality Safety on Campus
The most common class of crimes on college campuses are related to sexual assault and harassment. Having the ability to prevent an assault before it happens will make every member of your community feel safe.
In lots of states, it’s also illegal for a sex offender to be within 500-1000 meters of school campuses. Regardless of the age of your students, CCTV for schools can prevent any intruders.
Non-sexual forms of harassment are also one of the most common complaints on schools. Bullying is a serious issue that needs to be dealt with as soon as it occurs. Having cameras on campus will let bullies know they’re being watched.
Everyone will feel their identity and safety are respected and protected when there is a good system of security on your school grounds.
Should you end up in any kind emergency situation, whether it’s weather-related or an incident of terrorism, CCTV in conjunction with a PA system can save lives. You can direct your students away from the source of the incident toward a safe space
CCTVS In Educational Institutions
CCTVs are typically used by the government or private agencies for surveillance in areas frequented by the public that need monitoring. Recently though, universities across the length and breadth of the country have resorted to the use of CCTVs for policing campus activities and to keep the students in check and under control. Huge budgets are set to wire campuses with CCTV infrastructure, t causing students to protest as well as laud the initiative by the administration. The debate on CCTVs has gained momentum in recent years with students staging huge rallies both in support of and against it.
CCTV for Schools and Colleges
While there hasn’t been a significant increase in overall crime on school campuses, there are still a number of schools where students and staff are open to incidents. Whether you’re one of the schools dealing with crime problems or you want to ensure you don’t have to, prevention should be your priority. Used in conjunction with other security measures, CCTV for schools is a great way to reduce crime and ensure accountability.
Even though some might object to an invasion of privacy by placing cameras everywhere, there is a way to increase surveillance while respecting everyone’s rights. Taking their security into account will be appreciated by most visitors to your campus as well as their parents and families. If you’re looking for a useful and deterrent security solution for your campus, here are the reasons why you should consider a CCTV system. Guidelines and policies regarding the implementation of CCTVs and students remain unaware of any decisions in this regard. The Universities should clearly spell out their take on CCTVs including

CCTV applications
Crime management
CCTV surveillance can deter potential criminals. When a crime does occur, video footage can help law enforcement to investigate and later provide evidence for prosecution in a law court. Used in conjunction with CCTV, audio, thermal and other types of sensors can alert officials to occurrences that are out of the ordinary, e.g. a fire or gun shots at a location. For businesses, CCTV cameras can detect and monitor in-house criminal activities. Prisons may use video surveillance to prevent drones from delivering drugs and other contraband to prisoners. Security cameras are able to monitor areas that are not easily accessible, e.g. rooftops.
Disaster management
Using CCTV cameras, emergency services and rescue workers are able to assess and monitor events in real time to relay a “situation” via video to disaster management teams, e.g. from inside a burning building, from a cave or from a helicopter flying over a scene.
City and community street monitoring
Cameras at traffic lights and elsewhere in cities monitor people to gather traffic statistics as well as evidentiary footage for speeding.
Conclusion
The decisions to use CCTVs as a means of surveillance evokes mixed responses. On one side of the debate they are seen as a deterrent to crime while on the other side of the debate they are seen as being gross infringements on privacy. CCTV surveillance remains as a bone of contention amongst students. If they feel that their personal space is being invaded by these cameras then it needs to be addressed by the administration in a manner which appeases their fear. Universities randomly adopt the policy of CCTV surveillance, disregarding any voice of dissent. The rise of the CCTVs in colleges relates to not the actual crime but to the fear of crime. Therefore, CCTVs have become a tool of re-assurance which feeds a notion of safety and security to the authority in charge.
There is no black and white regarding the implementation of CCTVs in universities. A policy can only benefit both sides when decisions are taken with the students, and not on behalf of them. Indian Universities have no
