3.1 Installation & Connection
3.1.1 Basic connection and operation
3.1.1.1 Camera connection
Connect the DVR and CCTV cameras using coaxial cable as in the following figure.
- The cameras’ video input type must be one and only of NTSC or PAL. Both types should not
be used together.
- Automatic settings for 75Ω terminal resistance
While terminal resistance is generally 75Ω with only one video input port in use, when the
lower video input port is also connected, the settings automatically separate into 75Ω terminal
resistance while the status is Hi-Z (high impedance).
- The video input type (NTSC/PAL) is automatically recognized when the device is operation.
When multiple cameras are used, the video input type is taken from the first camera detected
starting from channel 1 and progressing sequentially to channel 16.
3.1.1.2 Monitor connection
Monitors connect to the DVR unit using a video cable as shown in the following figure.
