You have two plans: 1. Analog camera+video server 2. Webcam. I suggest you use a webcam for remote video surveillance. The installation and post-maintenance are very convenient, and the inspection and operation are convenient. You only need to connect the webcam to broadband, and you can realize remote video monitoring. However, the brand selection of webcam is very important. Sony, Panasonic, Samsung, Hikvision, Netscape, Dahua and other brands are all very good.
