The customers should consider the attributes to distinguish a CCTV and select the one that meets their requirements.
The output of the security camera is the video signal sent by the device to the display monitor. A CCTV will always send either any Analog or Digital Output Signal. Analog CCTV transmits a continuous stream of video over Coaxial cable and the majority of existing installations today are still using Analog technology. Digital CCTV transmits discrete streaming video over twisted pair cable and they are equipped with an Internet Protocol Address. CCTV cameras need a minimum illumination to capture the video properly and the sensitivity must fit the illumination level in the room where the CCTV is located. A control mechanism on the CCTV camera allows the user to adjust the camera’s angle and focus. Based on the control mechanism, a CCTV camera can be divided into a motorized and fixed device.
- A motorized device has a built-in motor to control the angle of view and focus remotely.
- A fixed device has a fixed angle and focus that must be set manually during installation.
