IP cameras
They are the main element of the system and are designed to capture video images. Thanks to the built-in network card, the IP camera has an IP address and a built-in web interface, which allows them to be independent devices. For example, you can insert a memory card to record an archive and connect it to the Internet to watch the camera online and events recorded to the memory card, from a mobile phone.
IP cameras can also be combined with other security systems, namely IP intercoms, security sensors, and access control. This way you get one security ecosystem on your phone in one app.
