Although not many analog cameras are used now, according to the data given by the monitoring and installation manufacturers, the analog camera market is still very large. Let's talk about what equipment is usually required for analog camera installation:
1. Analog camera (one or more)
2. Hard disk video recorder (or video capture card)
3. Video cable (or network cable instead of video cable)
4. Video cable BNC adapter
5. Camera power supply
6. Support (outdoor also includes vertical pole)
7. Terminal display equipment (a monitor is added to the video recorder, and a computer including the monitor is required for the acquisition card)

During installation, from the camera end to the display end, we first connect the video cable with the camera (we won't discuss the generic cabling), which can be directly connected between the BNC and the camera video head. The other camera is the power connector connected to the power supply, which is usually DC12V.

Then there is the power line in the middle, which connects the video line with the acquisition card or DVR at the control end. The acquisition card is installed on the computer host. Therefore, if the acquisition card is needed as the control end, it needs the support of the computer host, but if the control end is DVR, the computer host can not, as long as there is a display device.

After installing the connected and monitored hardware equipment, install the relevant software for software adjustment. Although the software of each manufacturer is not necessarily the same, it is generally the same. It can be set according to the instructions.

What equipment is usually required for network camera monitoring installation:
1. Network camera (one or more)
2. Hard disk video recorder (NVR or pc-nvr including software)
3. Router or switch
4. Network cable and make RJ45 network crystal head
5. Support (outdoor also includes vertical pole)
6. Terminal display equipment

During installation, we also introduce from the camera end to the display end, connect the network camera with the network cable interface, and then plug all the camera network cable connectors into the router or switch equipment. Now there are more Poe switches, and connect the network cable interface at the switch or router end to the relevant control equipment NVR.
