Ajax NVR: network video recorder on 230 V mains power
Record your Ajax and IP cameras in one place with 8 or 16 channels and a hard drive of up to 16 TB. View and manage everything in the Ajax app or through the built-in VMS. No subscription.
The NVR brings your Ajax cameras and third-party IP cameras (ONVIF/RTSP) together in one system, with motion detection, AI object detection and visual verification of Ajax alarms. It runs on standard mains power for a fixed installation. The footage stays local with you; remotely, you can view it through the Ajax app. NDAA-compliant and TLS-encrypted.
Why the Ajax NVR
Runs on mains power (230V)
Standard mains power supply 110-240 V. The familiar choice for a fixed installation with a socket nearby.
1 hard drive of up to 16 TB
Space for one SATA drive (2.5″ or 3.5″) of up to 16 TB. Choose your own capacity based on your retention period; the drive is not included.
AI and motion detection
Records selectively through motion detection and AI object detection. Choose whether the recorder or the camera performs the analysis.
Visual verification of alarms
Connect it to your Ajax hub: when an Ajax detector raises an alarm, the relevant camera image is displayed, so you can see immediately what is happening.
ONVIF & RTSP
Integrate Ajax cameras and third-party IP cameras (ONVIF Profile S/T, RTSP), or connect to existing recording systems (VMS).
Quick playback search
Video wall, smart filters and a timeline with smooth preview. Find events quickly in the Ajax app or the VMS.

Frequently asked questions
Is a hard drive included?
No. You choose your own SATA drive (2.5″ or 3.5″) of up to 16 TB, to suit your retention period. The drive uses a maximum of 7 W.
What is the difference between NVR, NVR DC and NVR HAC?
The NVR runs on 230 V mains power, the NVR DC on low voltage (9-16 V) for locations without mains power, and the NVR HAC has an HDMI output for local viewing and operation on a monitor.
Does it work with non-Ajax cameras?
Yes, you can connect common IP cameras via ONVIF (Profile S/T) and RTSP. For full functionality, use Ajax cameras within the Ajax ecosystem.
Do I need an Ajax Hub?
Not for recording. For visual verification of alarms and notifications in the app, connect it to an Ajax hub.
Are there subscription costs?
No. You record locally on the drive and the footage stays with you.
