Choose to install a hard disk video recorder to store and control the information collected by the camera. Generally, it is not recommended to install the monitoring card directly on the computer, because the camera needs to be used 24 hours, and the computer must be turned on 24 hours, which is not conducive to computer heat dissipation and virus prevention and control. It is suggested to install a hard disk video recorder, which is as convenient as DVD. There are many brands of hard disks to choose from, ranging from 100 to 700 yuan. For example, Joan, Di Fang and Hikvision can choose according to their own needs. Remember to distinguish between on-site monitoring and network monitoring, so as to determine whether to choose a hard disk video recorder with network function.

The choice of route is also a factor that affects the price. You can use direct wiring or wireless routing. Of course, wireless is more expensive, and the transmitted signal is easily affected by physical factors. Direct wiring is recommended. According to the actual access situation, determine the cable length. Brand and quality also determine the price. Generally speaking, 100-300 is enough.

Finally, it depends on whether workers need to install it, which is another expense. General installation fee is 50-200 yuan. I suggest you buy the whole set directly from the internet and then install it yourself. It's not technical, but it takes some time.
