Operation Manual

4.4.3. Connecting the Camera
Guidelines for this connection:
- If the IP camera provides the Alarm I/O port or Audio I/O port, you can make the alarm or audio connection. For
more details, please refer to the user manual of the IP camera.
- The Ethernet connection is effective within 100 meters in distance. Beyond that, you may encounter a data loss
or failure to connect to the camera. If you need to make a cable connection that is longer than 100 meters, please
use a separate PoE extender for cable extension.
- The total power consumption of the IP cameras should not exceed the rated power capacity of the 48V PoE
adaptor (Main Unit: 95W, External PoE Hub: 72W)*. If it exceeds the nominal power capacity, the video may not be
played properly or no video will be displayed at all. If this is the case, use a separate (additional) power source for
supplying power to the cameras.
*Only for the 16Ch NVR model GRI-K4416A.
- Per channel the NVR max. supplies 15W. If a camera requires more power, please use an external power supply
for this camera.
- For stable operation, a dedicated communication line is established for IP cameras in the same network. This is
why network router or hub connection is not allowed.
You can connect an IP camera with PoE connection to the rear RJ45 port ([CAM1]~[CAM8]) using the CAT5
10/100Mb Ethernet cable without a separate power source.
