CHAPTER 3: Installation

4. Connect the external power supply to the hub, then plug it into an AC power
outlet. If power is present, the green power LED will be on.
5. Power on the CCTV cameras and DVR. When a video signal is detected, the
green LED on each hub port will turn on.
6. Due to the hub’s automatic gain control, the camera images may take a few
seconds to stabilize. This is normal. The hub automatically adjusts the
brightness, sharpness, and color to compensate for effects due to the cabling
conditions. Use the adjustments on the CCTV camera, DVR, or monitor to
fine tune the final picture.
7. If there is visible low-frequency background noise (appears as a wood-grain
pattern) in the picture, connect the hub’s ground lug to a true building
ground. See Figure 3-8 for a typical configuration.
