Basic Connection Diagram

The following configuration diagram depicts a basic sample configuration that include cameras, monitors, sensors, and relays. These diagrams are representative only and are not intended to depict the only possible configurations for the SVR-1670.

Connecting Cameras

1.Ensure that the SVR-1670 is not connected to a live power source.

2.Using video cable, connect up to 16 standard CCTV cameras to the SVR-1670. Follow the instructions provided with the cameras to connect them to an external power source.

Figure 3.3.2 Connecting Cameras to the SVR-1670

Never connect both NTSC and PAL cameras to the SVR-1670 at the same time. The SVR- 1670 recognizes only one camera type at a time.

The following default settings are assigned to cameras that are connected to the SVR-1670.

·Video input type, which is determined by the device that is connected to the lowest channel number. For example, if there are five cameras connected to the SVR-1670 and the lowest channel number in use is 6, then the SVR-1670 will set the video input type to match the camera connected to channel 6.

·Terminal resistance, which the SVR-1670 automatically sets at 75Ω when one video input port is in use. When a lower video input port is also connected, the SVR-1670 automatically separates the terminal resistance between 75Ω and Hi-Z (high impedance).

About Video In and Out Connections

The SVR-1670 video input/output connections are “Loop through." Their connection status is detected automatically to set terminal resistance.

For example, when only video input is connected, terminal resistance is set internally to 75Ω. When video input and output are connected, terminal resistance is set to Hi-Z. This setting for input and output connections sets the external output device to 75Ω for terminal resistance.
