CCTV
CCTV systems are one of the most common forms of surveillance available today -- an affordable and reliable way to safeguard your business and people.
CCTV (Closed-Circuit Television) systems are one of the most common forms of surveillance available today. These systems use cameras to capture video footage, which is then transmitted to a monitor or recording device for viewing and storage.
CCTV systems offer an affordable and reliable way to safeguard your business and people. They can be used for perimeter security, monitoring entry points, tracking movement inside buildings, and providing evidence in case of incidents. Modern CCTV systems often include features like night vision, motion detection, and remote access capabilities.
What to consider
- Resolution and lens choice - higher resolution cameras provide clearer images but may require more storage space
- Low-light performance - ensure adequate illumination or choose cameras with good low-light capabilities
- Recording storage and retention - plan for sufficient storage capacity based on camera count, resolution, and retention period
- Compatibility with the VMS or NVR - ensure all components work together seamlessly
- Cyber security and firmware updates - keep systems secure with regular firmware updates
