The house is a rental house, and I am worried about thieves. In order to ensure the safety of the tenant's property, I want to install surveillance, so that I can know the situation even if there is a theft accident. What do you need?

The first option is to use a computer as a monitoring system. The cost is low and economical, but the compatibility is poor, and it is easy to be poisoned or the system is unstable. The specific configuration is as follows:

1. Computer + surveillance video capture card + software = surveillance host (you said that you don't need independent monitoring, as long as you can watch it, this is not necessary, but it is better to install one, which is convenient for video recording, and there is evidence for what happened , the public security organs are easy to check).

2. One box of video cables + one batch of BNC connectors.

3. 4 network cameras with front-end sony or sharp chips + 4 lenses.

4. A monitor.

The above equipment can be integrated into a small security system, which is sufficient for home use. If not, go to the local electronics market to find someone to build it.

The second scheme, using the embedded hard disk video recorder as the main control of the monitoring system, is as follows:

1. One hard disk video recorder (monitoring host), (it is better to install one, which is convenient for video recording, and there is evidence for what happened, and the public security organ can check and confirm it later).

2. A box of surveillance video cables.

3. One batch of video terminal BNC connectors.

4. 4 network cameras with front-end sony or sharp chips + 4 lenses.

5. A monitor.
