CCTV

Security cameras, also known as CCTV or “closed-circuit television” cameras, use radio frequency and send images or video recordings of a particular area to a designated storage device like a DVR or SD card. Security cameras connect either wirelessly or by using multiple cables, and typically use a television to broadcast signals. They also usually only activate when motion or sound is detected.

Surveillance cameras, also known as IP or “internet protocol” cameras, send real-time recordings to a central location within a local area network (LAN), such as a monitoring station. Despite the name, an internet connection isn’t always required for an IP camera to work. Surveillance cameras connect wirelessly or through a single Ethernet cable, known as Power Over Ethernet (PoE), and transmit signals through the LAN, Wi-Fi, or a cellular network. Compared to security cameras, they provide continuous recording.
