12V PSU for NVR is a power supply unit designed to allow an Ajax NVR to operate from a low-voltage power source instead of the standard 110/230 V~ mains supply. The module replaces the default internal power supply unit inside the NVR enclosure.
By powering the NVR from a low-voltage source such as a backup battery system, the device can continue operating during power outages. This ensures uninterrupted video recording and reliable surveillance, making it ideal for facilities with unstable or unavailable mains power.
