Types of Security Cameras

Based on the connectivity technology used by different cameras, these can be divided into two main types, including analog cameras or IP cameras.

Analog Cameras are a type of security camera that captures video footage in the form of signals. These signals are then transferred to recording devices, such as a digital video recorder (DVR), via coaxial cables. These cameras lack modern features such as motion detection and audio or video analytics. They primarily record basic videos.

IP Cameras:

IP Cameras, on the other hand, use modern digital technology and transfer videos to an IP Network. These cameras don’t require a separate storage device as most of the footage is either stored on the camera or a cloud server.
