Choosing and Setting Up A Video Surveillance System

Locksmith Ledger kicks off a series of articles that address the basics of video surveillance.


To connect the LD6122 camera to the switch, the dome must be removed in order to connect a CAT 5e cable. The dome is secured using four hex head screws that are loosened using the provided hex wrench. The LD2222 has a pigtail that extends from the dome with both an RJ-45 and DC12V connector.

The CAT 5e cables are plugged into one of the eight connectors in the front of the switch. A CAT 5e cable connects the switch to the NVR using one of the two combo Gigabit UTP ports.

For this installation, an HP Touch Screen Monitor was connected to the NVR. When connecting a monitor to the NVR104, the connection is a standard HDMI port. Some monitors do not have an HDMI port and an adapter cable is required. Many newer monitors have a DVI port. Use an HDMI to DVI cable to connect the monitor to the NVR.

Once all of the components have been connected, power the system.

Depending upon the number of cameras, an image may appear from each of the cameras on the screen. If not, LILIN has a WS-Discovery feature that finds and identifies each of the cameras. For this article, only one camera provided a live image. In addition, four shortcut symbol keys appear in the top left corner of the display. They are a gear that indicates the menu, two vertical bars that indicate pause, a dome that indicates the alarm and a downward arrow in a circle that indicates backup.

Use the touch screen and select the gear. This will bring the main menu horizontally across the middle of the screen. There are nine main menu keys. Because only one camera’s image appeared, we need to discover the second camera before setting the addresses. Press the Configuration Menu, which is also a gear.

On the left side of the Configuration Menu screen is a list with Camera at the top with the Camera window to the right. Scroll down to the “WS-Discovery.” Press the Enter button to the right. Depress the IP SCAN button to search for available cameras. The second camera’s image appeared on the screen.

In the next installment of our Video Surveillance series, we will continue our discussion of the recording features of the NVR104.
