The Ajax NVR H2D Series delivers professional 4K IP video surveillance with 8 or 16 recording channels, dual hot-swappable HDD bays, up to 32 TB of storage capacity and optional integrated PoE ports. Featuring ONVIF compatibility, Ajax JetSparrow technology and remote video management, this network video recorder is ideal for commercial security, offices, warehouses and residential CCTV installations across Australia and New Zealand.
Double the Storage. Double the Confidence.
Designed for dependable, continuous video surveillance, the Ajax NVR H2D Series combines Ajax security cameras and compatible third-party IP cameras into a unified video management ecosystem.
With two SATA III drive bays supporting up to 16 TB each, the recorder offers flexible video storage for applications requiring extended footage retention or additional recording protection.
Two selectable recording modes allow users to prioritise storage capacity or data redundancy.
Redundancy Mode duplicates recorded footage across both drives, helping preserve recordings if one drive fails.
Split Mode distributes recorded footage across both drives, balancing storage usage and providing greater effective recording capacity.
Unlike conventional recorders requiring a shutdown for drive replacement, the Ajax NVR H2D supports hot-swappable storage, allowing maintenance without switching off the recorder.
4K HDMI Output and Professional Local Monitoring
The integrated 4K HDMI output transforms the recorder into a professional on-site security monitoring station.
Connect a compatible display and USB peripherals to access Ajax's built-in video management system (VMS), including live camera monitoring, recorded footage playback and event investigation.
Its customisable video wall supports multiple viewing layouts, making it easy for security operators to manage different areas of a property from one interface.
Remote Surveillance Powered by Ajax JetSparrow
Ajax JetSparrow technology provides fast, encrypted video streaming and responsive archive navigation through supported Ajax applications.
Authorised users can remotely:
-
View live camera footage.
-
Access and navigate recorded video archives.
-
Review security events and associated footage.
-
Search recordings using event filters and timelines.
-
Export relevant video clips.
-
Manage cameras and recording configurations.
-
Monitor multiple camera streams using the video wall.
The system supports convenient security monitoring from compatible smartphones, computers and other supported devices.
Seamless Integration with Ajax and Third-Party Cameras
The Ajax NVR H2D Series supports Ajax video devices and compatible third-party IP cameras using ONVIF Profile S and RTSP.
This flexibility makes it suitable for new CCTV installations, existing surveillance system upgrades and integration projects that combine multiple camera technologies.
PoE-equipped versions can connect and power compatible IP cameras directly through built-in PoE ports, reducing the need for separate camera power connections.
Security-Focused Video Management
The Ajax NVR H2D combines surveillance performance with configurable privacy controls.
Device owners can manage user permissions for video streams, recorded events and recorder settings. This helps ensure surveillance information remains accessible only to authorised users.
Integration with Ajax security events also allows associated camera footage to be highlighted for faster visual alarm verification.
