2. CCTV SYSTEM There is a phrase commonly used among internet users i.e. “Nothing is Safe”. Adhering to this phrase industries have been trying from years to come up with security systems that are completely safe. But this task has been almost impossible as always there is some or the other bugs found. Nevertheless there are certain products which have been very efficient in their working such as CCTV Cameras, spy pens, etc. The main focus here is over CCTV Cameras, its usage and future advancement in the latter.

3. How Do CCTV Cameras Work? CCTV camera systems has one or more cameras which are used to send video, images and audio data to a monitor. Essentially, these camera systems use cameras to transmit the signals to a main hub which then records that data for later viewing or live viewing if you have full time security personnel on your premises.

4. Types Of CCTV Cameras CCTV cameras are being installed every where for purpose of security and crime prevention and detection. There are many types if CCTV cameras are available for this purpose. These are: Indoor Camera Outdoor Camera IR Day/Night Camera Dome Camera Bullet Camera Vandal Proof Camera Hidden Camera Pan Tilt Zoom Camera

5. Types Of CCTV Systems CCTV Systems are broadly divided into two types. These are: Wired CCTV System: Wired CCTV systems connect the camera to the recording device and monitor with the help of standard coaxial cables or Unshielded Twisted Pair(UTP) cables or fiber optic cables. The image data is usually transmitted over a coaxial cable. The signal transmitted over these cables is then fed into a monitor or set of monitors if the image needs to be visible indifferent locations. Wireless CCTV System: Basically, Wireless CCTV systems are similar to wired CCTV systems. The difference is that a radio transmitter is attached to the camera. A radio receiver then attached to the input on the monitor system or computer. Wireless systems are useful when the distance between the camera and the monitor is too far to be practical for a cable run.

6. Applications Of CCTV CCTV is commonly used for a variety of purposes, including: Maintaining perimeter security Observing behavior potentially dangerous patients in medical facilities. Traffic Monitoring Building and ground security. Overseeing locations that would be hazardous to a human. for example, highly radioactive environment. Obtaining a visual record of activities where it is necessary to maintain proper security. for example, in banks, casinos, or airports.

7. The Future Of CCTV Cameras The future of CCTV is – IP CCTV. IP CCTV stands for Internet Protocol – Close Circuit Television. With IP CCTV the video management has become so simple. You can store and retrieve both analog and digitally recorded video footage and access it via an internet connection anywhere in the world. Especially with the growth of Cloud Computing, the IP CCTV has seen a massive boom.

8. Conclusion When used in moderation, under the correct guidance, Surveillance cameras can be invaluable in aiding the police in their investigations. CCTV can also act as a twenty-four hour police presence, helping to make the public feel safer. If used excessively however, the massive increase in the number of CCTV cameras can lead to an invasion of privacy and violation of human rights. The cost of the cameras has also been an issue that has caused many debates as to whether the cost is worth the results. There needs to be reform into how the authorities use the existing surveillance cameras to enhance their effectiveness to their impact on crime.
