Ajax 12V PSU for NVR

£29.95

sku: AJAX-112255

A replacement internal power-supply board for powering compatible Ajax NVRs from a low-voltage DC source.

For installation by a suitably qualified installer. Check compatibility with the exact NVR.

Shipping From:

When ordering multiple Keyed Alike locks, only 1 set of keys are provided as all additional locks are made to work from that key.

If ordering 4 or more keyed alike locks you can have them set up as different groups. If Required: Let us know the details in the "Specific Key Requirements" field above.

Each group of locks will then receive keys.

Ajax Baseline

NVR power, adapted. For a suitable low-voltage source.

This internal power-supply board allows a compatible original Ajax NVR to use a low-voltage DC source. It is a specialist installation component, not a plug-in camera adapter.

Installation is part of the specification.

The board replaces the original NVR power-supply board and must be fitted with power disconnected by a suitably qualified installer. Check the exact NVR compatibility and source requirements against the current manual. It is not a PoE injector and does not add camera-power ports.

The compatible recorder. Real products. The right connections.

What you need. Fitting and setup.

Before installation

  • A compatible original Ajax NVR and a suitable external DC power source within the board's specified input range. Do not assume compatibility with NVR H or NVR H2D.
  • A qualified installer to replace the internal power-supply board and check the input configuration, polarity and supply capacity against the manual.

Fitting and setup

Disconnect all power before opening the recorder. The installer replaces the existing internal board using the manufacturer procedure, reconnects the required cables, secures the enclosure and tests recorder operation and recording afterwards.

This is an internal conversion board, not a plug-in camera adapter or a way to add PoE outputs. The NVR still needs its network connection and recording drive.

FAQs

Not generally. Mounting patterns, cable entries and enclosure dimensions vary. Use the accessory's stated compatible models rather than assuming a universal fit.

No. A junction box provides a mounting and cable-management arrangement. Camera power must be provided separately using equipment that meets the camera specification.

No. Voltage, current capacity, polarity and connector type must all match the device. A recorder-specific supply is not automatically suitable for cameras or other equipment.

No. It is an internal replacement board for a compatible original Ajax NVR, not an external power adapter for cameras.

Do not assume compatibility with NVR DC, H or H2D. Check the exact recorder and Ajax installation manual before ordering.

No. The board adapts the recorder to a suitable low-voltage source; it is not a battery or complete backup-power system.

Ajax Baseline

Keep the moments that matter. Without a bulky recorder.

Ajax NVR brings multiple camera streams into a compact recorder. View and search footage through the Ajax apps while the archive stays on a compatible local hard drive.

NVR

The archive, neatly contained.

A single compatible SATA hard drive, up to 16 TB, stores the footage locally. Eight- and sixteen-channel versions suit different camera counts, without changing the way you use the Ajax apps.

Recording without a noisy desktop box.

The original NVR uses a compact, fanless enclosure with one SATA drive bay. Its eight- and sixteen-channel models suit shared recording for several cameras without putting a computer beside them. Viewing and configuration take place in Ajax apps; this model has no HDMI monitor output.

Ajax NVR enclosure and hard-drive installation

Privacy includes the archive.

Authorised users control access to live video and recordings. Ajax supports two-factor authentication, session management and separate permissions for video access. The recorder monitors the hard drive and reports problems through the app, helping you check that the system is still recording as intended.

Bring supported cameras together.

ONVIF Profile G and S and RTSP provide connections to compatible third-party cameras alongside Ajax video devices. Pixel-based motion detection can define recording areas, while available AI filters depend on the connected camera. An ONVIF connection does not automatically provide all of a camera manufacturer's proprietary features.

Ajax and compatible third-party cameras connected to an NVR

The right recorder. For the way you use it.

Compare this recorder with the alternatives below. Match camera capacity, screen connections, recording storage and power to your installation. You need one suitable recorder for this role, not all of them. Hard drives are supplied separately.

Only the PoE-equipped H2D models power compatible wired cameras directly. Other versions need a separate PoE switch, injectors or the camera's specified power supply.

A moment, easier to find.

Event filters and configurable motion-detection areas make a long archive more useful. Use the timeline to find activity, rather than treating every hour of footage as equally important.

Your whole property. In one view.

See the front door, driveway and garden together instead of opening each camera in turn. Arrange the Ajax video wall around the views that matter to you, and check them from a compatible phone, computer or TV app.

Separate the three jobs. Network, power and recording.

NVR Network Video Recorder uses 110-240 V AC. It records network camera streams but has no PoE camera-power ports. Connect cameras through suitable network equipment and power them separately. The hard drive is supplied separately; a hub is only needed for the associated alarm functions, not basic video recording.

This manufacturer diagram shows video and network communication, not a physical power-wiring plan. Installation requirements depend on the exact equipment.

Build around it. Real products. The right connections.

These are compatible camera choices and separately supplied power options. Use one suitable switch to power wired PoE cameras; it does not power the recorder itself. IndoorCam and DoorBell have their own power arrangements.

What you need. Fitting and setup.

Before installation

  • A suitable mains supply for the recorder and an Ethernet connection to your router or network switch.
  • A compatible recording drive, supplied separately. Fit and secure it inside the recorder with the power disconnected.
  • Separate power for the cameras: for PoE cameras, plan Cat6 runs to a suitable PoE switch or injector. This recorder has no camera PoE outputs.

Fitting and setup

Place the recorder securely with ventilation space, connect it to the same network as the cameras, then add it to the Ajax app. Add the cameras, configure storage and recording schedules, and test playback and user permissions before handover.

This model is managed through Ajax apps; it has no HDMI monitor output.

Powering the cameras, not the recorder

For wired PoE cameras, the Uniview switches provide 4, 8 or 16 powered ports; the 16-port Reyee is another managed option. Connect the switch's network uplink to the same network as the recorder. Match powered-port count and the shared PoE budget to the cameras, allowing for their maximum demand rather than treating channel capacity as a power rating.

These switches power compatible Ethernet cameras, not the recorder itself, IndoorCam or DoorBell. The recorder still needs its own specified supply. Keep networking equipment indoors with ventilation space.
