Common Types of CCTV Surveillance Cameras
- Analog Security Cameras include basic security functionality, onsite video storage, and video display on TV without the need for a Digital Video Recorder (DVR).
- Internet Protocol (IP) Cameras offer similar functionality to analog cameras but have higher resolution, remote zoom, repositioning capability, and can receive real-time images and notifications via a web browser or other software. That means live incidents can be viewed on-premises or remotely from a smartphone or desktop computer.
