I want to install a video camera or something at home, or a computer camera, so that I can see the situation at home in other places and who goes to my house at ordinary times.

The idea is good and can be realized, but overall, it may not work very well. This can be done simply.

1, buy a surveillance camera. If it is a home computer, it is recommended to control it within 4. Buy 4 Luther video capture cards (usually with software).

2. Connect the camera to the video capture card, install the software, and keep the computer on all the time (of course, your hard disk should be large enough. If you record for a long time, it is recommended to change it to 1T). The software has been in the state of monitoring and video recording.

3. Set up remote access, so that you can check your home in other places with your mobile phone or networking device. Of course, if you use a mobile phone, the traffic may be a bit heavy.

It may be simple to say, but it is still difficult to operate in practice. So I suggest you close all the doors and windows at home. The main function of monitoring is to obtain evidence afterwards. Even if you see someone stealing and call someone to go, it is estimated that people have run away.

Another simple way is to buy some simple alarms. When someone invades, they will automatically call the police. This is relatively simple to implement. If the alarm rings, the thief should also run away. Ha ha! Personal advice, for reference only!
