Continuous video recording is easy with Ajax, even in locations with unstable or no electricity. To achieve this, connect NVR to a portable battery or a low-voltage power source using the 12V PSU. It is an electronic board that replaces the standard 110/230 V~ power supply unit within the video recorder enclosure. This enables NVR to operate on a low-voltage power source instead of the facility’s power grid. This setup is ideal for construction sites — whether active or frozen — that require protection of territory, materials, equipment, or critical infrastructure, ensuring non-stop surveillance during power outages.
