For this second part of our series, we will continue with the basics of a standalone video surveillance system using high definition video cameras. Because this is a basic installation, we will not connect to the Internet or use a personal computer. The network video recorder (NVR) will provide all functionality. In a future article, we will discuss Internet connectivity.
This standalone, basic video surveillance system is comprised of a Lilin NVR104, Eight-Port PoE+ Fast Ethernet Switch, two cameras and a touchscreen monitor. The Lilin NVR104 has the capacity for up to four channels (cameras) of real-time recording, providing up to 24Mbps (Megabits per second) throughput. This embedded, standalone NVR supports up to two SATA hard drives and one eSATA hard drive.
Two cameras, a Lilin IPD2220ES and a IPD6122E3.6, are 1080P HD IP Dome PoE (Power over Ethernet) cameras, having 2 mega pixel CMOS image sensors. The two cameras have true H.264 AVC/MPEG-4 part 10 real-time video compression. The H.264 AVC video compression engine supports high definition video quality, 1080P (1920x1080) resolution, bandwidth efficiency.
Each camera is connected using a Category 5 (CAT 5) cable to the Lilin Eight-Port PoE+ Fast Ethernet Switch. The Ethernet switch sends the throughput to the NVR and up to 30 Watts per port to power each of the PoE cameras. This eliminates the need to run separate power to each camera.
A CAT 5 cable connects the switch to the NVR. The touchscreen monitor is connected to the NVR, providing the ability to control system operation with your fingers. Additional functions include “pinch and zoom” and other smartphone-type finger operations. If a touchscreen monitor is not available, use the included USB mouse to setup and control the NVR.
Important: Always power the accessories - monitor, cameras and Ethernet Switch - before powering the NVR. When powered, the Ethernet Switch displays which ports are powered and linked to a camera.
Once the NVR is plugged in, the Ethernet Switch LEDs will illuminate for each camera. The monitor will display four symbols (shortcut keys) in the top left corner: Menu Key, Pause Key, Alarm Key and Backup Key. Using the NVR104, two icons are displayed at the bottom center, showing the cameras’ screen views. They are the single view and the four-view configurations.
Pressing the Menu Key brings up the Main Menu Keys displayed along the center of the screen: Off Key, Alarm Key, Live Key, Backup Key, Record Key, Setup Key, Event Key and PTZ Key. To complete the basic setup started in the first part of this series, press Setup Key.
The screen that appears has menu settings for cameras, monitors, recording, alarm, system, network, and PTZ (Pan Tilt Zoom). The default screen is for programming the cameras starting with number one. Find WS-Discovery and press the Enter button at the right. A new screen appears. Press the IP SCAN button if not all of the connected cameras appear on this screen. The IP Scan feature searches for available cameras within the system. The second camera’s image appeared on the screen.
Sometimes it is necessary to make some changes for the camera to appear. A call to Lilin Technical Support helped to resolve the second camera. To simplify identifying each camera, use “Get Snap”to take an image from each listed camera.
Once all of the cameras have been listed and identified, the next step is to press the “X” in the top right corner, which will return to the previous camera screen. Note: Every time the “X” in the top right corner is pressed, it returns to the previous screen.
It is a good idea to name each camera, usually giving it a location. For this article, we will change the cameras’ names from CAM01 to Overall View and CAM02 to Fixed Point, since this setup is in a residence. Note: Normally it is recommended to name the camera for what it sees.
