A camera is a device that captures visual information and converts it into digital or analog signals for display, recording, or analysis. In surveillance, cameras are essential for monitoring, detecting incidents, and ensuring safety.
For example, IP cameras transmit footage over a network, while analog cameras use coaxial cables. Both types support features like motion detection, night vision, and remote access.
While some cameras are fixed, others offer pan-tilt-zoom (PTZ) functions for wider coverage. As a result, users can choose models based on location, lighting, and security goals.
By using the right camera, organizations strengthen situational awareness and improve threat response.
