The first thing is design.

Most of our surveillance installation scenes are family homes, shops, industrial plants, etc., basically more than four cameras. If only one or two cameras are installed, then you can directly select the webcam version of network plug-in card.

In view of the influence of monitoring threading, power connection, camera installation location and other factors, we must first check the installation location of the equipment, threading location and power supply selection before installation, which will reduce a lot of trouble for your subsequent work.

Select the camera.

Camera choices can be blurry for the uninitiated, and you can go online and search for brands and models you haven't heard of, along with a plethora of fancy features to keep you from getting started. So at this time we can find a specialized service company as a reference, or to let them from the service to the installation of a one-stop service.

But in the installation of the first to determine whether it is indoor or outdoor installation, indoor is a hemisphere machine, outdoor is the gun, it is to understand that the hemisphere machine is basically not waterproof, is applicable to the room does not occupy a place, more hidden.

The switches on the monitor are basically classified into normal switches and POE switches. If you are a POE-powered camera, the POE switch is required to cooperate.

The monitoring device has its own dedicated hard disk, often referred to as the purple disk.

Monitor on the hard disk requirements are very high, hard disk write speed to be stable, with a long time stability, because the monitor hard disk needs 24 hours of uninterrupted read and write, constantly erase the written data, ordinary hard disk can not be competent for such a high intensity of work.

Bought secondhand common hard disk to serve as monitor hard disk before, it is covet cheapness, basically it was broken before long, anyway also be the gain outweighed the loss.

(Never lose power suddenly while the VCR is working, and the hard disk burns out easily.)

Network and power lines.

Net line we must choose 8 core, line diameter is the thicker the better, the material to choose oxygen free copper, and the poor quality of the wire is aluminum wire or copper clad aluminum wire this do not buy.

If installed outdoors, choose an outdoor net with a waterproof cover.

The power line is also pure copper, also divided into indoor and outdoor two kinds, line diameter as thick as possible, otherwise it may cause insufficient power supply.

Above is the equipment you need to buy to install monitoring, we will buy according to their own needs, I hope these can help you.
