A security camera, or surveillance camera, is a closed-circuit television (CCTV) camera used to monitor areas for any suspicious activity or other phenomena of interest. Some key points about security cameras:
- Monitor areas of interest for safety, security, and surveillance purposes. Things like unauthorized access, vandalism, theft, etc.
- Contain lenses and image sensors that convert optical images into digital video signals for recording and monitoring.
- Connected to a video or network video recorder that records the footage. The footage can then be reviewed if any incidents occur.
- Common types of security cameras include dome cameras, bullet cameras, box cameras, PTZ cameras, covert cameras, etc. Depending on the needs, they differ in features like weather resistance, night vision, zoom, etc.
The key features of security cameras include weather resistance, night vision, motion detection, remote access, two-way audio, etc.
- They help deter criminal behavior through visible surveillance. The cameras can also be used to identify offenders by recording visual evidence.
- The footage from security cameras can also be used for analysis, e.g., counting people entering/leaving a location, tracking vehicle movements, etc.
- Newer IP security cameras can stream and record video over a network connection. This allows for centralized monitoring of cameras installed in multiple locations.
- Security camera systems require proper installation, configuration, and monitoring to operate effectively and meet security objectives.
