Learn How CCTV Cameras Operate
CCTV (Closed-Circuit Televsion) is the utilization of video cameras to transmit live recorded data to a set of monitors. Maintained in a closed loop so that there is completely no other system can access. This device is commonly used in places that need monitoring and constant observation.

Along with technology development and transition to digital, system costs have fallen considerably. The main criteria for qualification and types of video surveillance systems are:
- Types cameras based on position: indoor and outdoor – Interior room types: miniature, hidden, box, bullet, dome, IP – Types outdoor rooms: box, bullet, dome, wireless – Rooms based on lens types: Wide-angle (large angles) and normal – Room types based on sensor: CMOS, CCD, color, black & white
How does it work?
Information is registered through the CCTV camera then transmits it to the server. The purpose of the server is to collect and save the data gathered. It can also be used to display them instantly on the screens. The system can also be connected to the internet for portability. DVR’s or commonly known as Stand Alone Digital Video Recorders may be used depending on the needs and the system.
Completing the connection to accomplish the transmission from the server
Method 1: UTP Cable Method 2: coaxial cable Method 3: Wireless Method 4: Fiber Optic
The decision should to be taken depending on the available budget.
Areas of deployment
The CCTV cameras can be found indoor or outdoor. Whether they are indoor or outdoor, some are weather and tamper proof r while others do not, various cameras may make out in complete darkness using infrared, others not.

Figure out if the camera needs movement whether vertical, horizontal or both. Calculate the optimum distance. All these small details are needed when installing CCTV cameras.
IP based systems have 32 bit numbers that is unique and perfectly works with CCTV cameras in networked systems. The cameras will be networked so that it can be view globally. This can be done due to the unique IP addresses being provided.
The CCTV cameras are digital and this is the reason they offer a very high quality of the image and all the information is digitally stored on the hard disk. Thus, there will be no danger of degradation of the quality of the image, like it might happen with the analog equipment.
