In the installation of surveillance cameras, we should consider the choice of preferred acquisition equipment, at present, there are mainly two kinds of commonly used video capture device security industry, a video capture card, another is DVR (DVR). If you choose the acquisition card as the main acquisition device, the implementation process is relatively complex, but the cost is low. The choice of DVR as a video capture device, it does not require too much expertise, simple operation, good collection effect.
If you want to collect the equipment, then determine the location and number of monitoring points. Before we buy surveillance cameras, we also need to conduct field visits to the monitoring environment to determine the number and environmental features of the monitoring points. After getting the number of monitoring points, you know how many cameras are needed. Then, in accordance with the different monitoring points, choose different grades of infrared surveillance camera can be.
After you complete the two steps above, then you'll see if you need night vision. If the newly installed monitoring point requires 24 hours of monitoring, you need to choose infrared night vision capabilities of infrared cameras. If you only need daytime monitoring, select the general color surveillance camera to meet the demand.
Finally, the routing options. At present, there are two routing methods in monitoring engineering, one is wired, and the other is wireless. If you have a high budget and a proper monitoring environment, you can use wireless transmission, so that you can save the tedious wiring work. If you want to save costs and want to ensure monitoring results, you can use wired wiring
