Is there a surveillance camera that doesn't use the internet?

There are surveillance cameras that don't use the internet. The main function of this camera is to record video, and there is no need for networking. A memory card needs to be installed in the surveillance camera. The recorded video will be stored in the memory card and can be taken out and played back on the computer. This kind of camera can only play a monitoring role. Without networking, other special functions such as voice call, voice intercom, real-time playback and real-time monitoring cannot be used. Most brands of cameras on the market can be used without WiFi, such as fluorite, Le Orange, Xiaomi and 360. In addition, there is a wireless surveillance camera without WiFi, which is connected to the Internet through a 4G card. Simply insert a 4G card into the camera to connect the camera with the mobile phone, and support the remote monitoring of the mobile phone and the computer.
