Bringing AI to any video setup

Ajax network video recorders integrate Ajax video devices and third-party IP cameras into a single ecosystem. Superior NVR H2D series features onboard AI, providing intelligent analytics to existing setups without costly camera replacements. The recorders can house two hot-swappable HDDs up to 24 TB each — optimal for continuous archiving and reliable backup. 4K decoding allows for seamless playback of multiple camera feeds at once. And with a wide selection of Superior NVR configurations, it's easy to build an efficient and flexible monitoring system for any facility — and manage it remotely via Ajax apps or on-site through the built-in VMS.

Intelligent upgrade for existing setups

Superior NVRs feature proprietary onboard AI, bringing smart Ajax video surveillance to even outdated setups. The recorders enable basic cameras to recognize people, pets, and vehicles — with the same accuracy as native Ajax cameras. Third-party cameras enhanced via Superior NVRs can also send detection notifications, trigger sirens, or run automation scenarios. All of this comes with a single Ajax Superior NVR, without the need for costly camera replacements.

Always-on recording without service breaks

All devices in the Superior NVR H2D series deliver continuous recording, even during maintenance. They support hot swapping, so installed HDDs can be replaced at any time without shutting down the recorder.

Full story preserved with two-drive recording

Superior NVR H2D series offers two recording modes designed to enhance system resilience. Both minimize the risk of data loss if one drive fails, always preserving sufficient context of recorded events.

Redundancy mode

Footage is duplicated across both hard drives to ensure a full backup.

Split mode

Footage is recorded alternately in equal segments across both hard drives, optimizing storage capacity and balancing HDD load.

Keeping track of critical events — at the desk or on the go

Superior NVRs easily adapt to any monitoring workflow. Ajax provides a full suite of mobile and desktop apps for comprehensive video management. These secure, cloud-based tools enable users to view the video wall, manage the archive, and adjust settings from anywhere in the world. And with 4K HDMI and three USB ports for connecting a display and peripherals, a full-fledged monitoring station can be arranged right at the desk. Whatever the setup, relevant events always stay in sight.

Designed to fit every project

Ajax NVRs come in a variety of options to suit any application or network design. The Superior NVR H2D series includes recorders that support up to 32 channels to cover systems of different scales. Models with PoE¹ ports can connect and power up to 16 cameras. Meanwhile, NVRs without PoE ports feature two Ethernet interfaces — ideal for connecting to industrial-grade switches on sites with strict network requirements.

Easy integration through ONVIF and RTSP

Ajax video devices support ONVIF and RTSP protocols — no special tricks, no extra effort. This opens up numerous opportunities to upgrade and retrofit existing video setups with advanced security features. Ajax cameras and NVRs connect to third-party surveillance or video management systems (VMS) in just a few taps. A special wizard tool in Ajax apps simplifies the configuration process by automatically retrieving all necessary network data. Enjoy smooth streaming and flexible image configurations, whether building a new setup or expanding an existing one.

Video surveillance that meets top demands

Ajax Superior cameras deliver everything discerning clients expect. They offer adjustable coverage for either extra detail or a wider view, giving sufficient context at all times. Equipped with a P-Iris lens, the cameras don't lose important details to shadows or glare. The enhanced AI distinguishes between people, pets, and vehicles with unmatched accuracy, notifying users once anything is spotted. And thanks to built-in hardware for two-way audio, Superior cameras empower instant response — no extra equipment required.

Customizable video wall for simultaneous monitoring

Streamline surveillance with a video wall that displays integrated video streams from all connected devices. Keep every corner of the facility in view — whether on an HDMI-connected display or via mobile and desktop Ajax apps. Rearrange the layout as needed to keep priority visuals in focus.

Smooth archive navigation

Ajax apps make finding recorded events faster than ever. Thanks to our proprietary JetSparrow technology, the system responds instantly, allowing for smooth playback and effortless navigation through the event timeline. Users may tap any event to jump straight to the relevant footage, filter recordings by date or object type, and export clips in seconds — all within a single, intuitive interface.

Instant event-to-video alarm verification

No more sifting through piles of footage to find a specific moment. Ajax video devices are fully synchronized with the system. Notifications in Ajax apps instantly redirect users to a relevant incident recording.

Set up scenarios for cameras to start recording as soon as certain Ajax detectors are triggered. Configure video settings to instantly receive high-resolution visual verification of alarms.

Rapid and encrypted data transfer

JetSparrow is the heart and brain of Ajax video transmission, storage, and management. We developed this video transmission technology to deliver an ultra-fast VMS experience. With JetSparrow, navigating through the local archive feels as smooth as browsing cloud storage. As a result, surfing the archive becomes remarkably efficient, and the live view initiates without any delay.

Peer-to-peer transmission

TLS encryption

High stability

Built-in motion detection

Save storage and simplify footage review by setting up pixel-based motion detection. Define specific zones where movement triggers video recording, so that only relevant events are captured. This conserves HDD space and makes archive navigation even faster and more efficient.

Privacy by design

Video data security

Ajax Systems ensures the highest level of video data security in compliance with EU data protection standards. Recordings are securely stored on the hard drive and can only be accessed with authorized credentials. The system continuously monitors the HDD state, sending instant push notifications via Ajax apps in case of overheating or low storage space.

The Privacy tab

The Privacy tab enables trusted accounts to grant or revoke user access rights to specific video streams and photos in real time. Users can control who can view, listen, save, and manage the content.

Access to video streams

Access to video streams is managed through the apps. Accounts can be secured with either a password or biometrics. Two-factor authentication and session control add extra layers of protection.

User-controlled system

Once installed, the system is exclusively controlled by the end user, with no backdoors. Access for PRO accounts is temporary, and only those with specific rights granted by the system administrator can access visual data.
