Before arranging the camera, you must first decide where your camera is laid and fixed at which point. What to shoot and how far away.

The fixed position of the surveillance camera is very important, as well as what kind of camera you are going to purchase. The parameters of the camera are mainly the effective distance.

2、 Installation of surveillance camera
If the network surveillance camera is connected to the hard disk video recorder, the following operations are required:

(1) Purchase one DC 12V power supply, one camera support (except hemisphere), one network cable of appropriate length, one power cable, or a combination cable, that is, there is both a network cable and a power cable in one cable.

(2) Place the camera in a proper position, connect the combination cable, and make a crystal head. One end is connected to the camera and the other end is connected to the switch. (the practice of crystal head is in my previous article)

(3) Pull a network cable from the switch to the hard disk video recorder;

(4) turn on the VCR, add the camera and adjust the camera angle.

In addition, if you do large-scale monitoring, the manufacturer must select it. Long term cooperation is the most important. The circuit diagram must be kept after completion. This allows for a later maintenance issue.
