Meet NVR H series, featuring HDMI output for local video monitoring

Ajax expands its video surveillance lineup with NVR H series. These network video recorders deliver an even more flexible video monitoring experience — via Ajax apps or locally on-site via the built-in VMS.

Where to buy

NVR HAC with HDMI and built-in video management system

Ajax network video recorders integrate Ajax video devices and third-party IP cameras¹ into a single ecosystem. NVR H series includes two models — NVR HAC (8-ch) and NVR HAC (16-ch) — supporting up to 8 and 16 channels, respectively. Both models are available in black and white.

These new NVRs are designed for local video monitoring. The devices feature an HDMI output and a built-in video management system (VMS). This enables live and archived video to be viewed directly on a connected display — no computer or laptop is required. Therefore, NVR H series is an ideal choice for small to medium-sized businesses, private residences, offices, and other facilities requiring on-site monitoring. Combined with cloud-based Ajax solutions, it offers professionals flexibility: monitor locally, access footage remotely, or combine both for complete situational awareness.

For example, hotel staff can monitor entire floors using existing displays and respond quickly to incidents, while in private homes, NVR HAC devices allow users to view surveillance footage directly on a TV.

The series is also a practical solution for sites without stable internet access, facilities requiring 24/7 autonomous operation, or locations with specific compliance demands for local video storage and access.

Built-in video management system

NVR HAC comes with a VMS that runs directly on the device. This eliminates the need for Ajax apps² or even a PC, as live streams and archive footage are viewable on a connected monitor. Navigating the VMS is effortless with a mouse and keyboard, and users can choose to log in with either a cloud account or a local account, depending on access preferences.

The VMS interface provides a convenient way to monitor multiple cameras at once. This is made possible with customizable video wall layouts that can adapt to different facilities and surveillance tasks. Layouts automatically switch with the slideshow feature, providing complete situational awareness with minimal interaction. Whether keeping watch over an office floor or a home entrance, users and operators can stay focused on what matters most by rearranging camera views in just seconds.

Users can scroll through the timeline, filter events by type, or switch to the calendar view to quickly access the relevant recordings.

Built-in motion detection

NVR HAC devices are equipped with a motion detection feature that constantly analyzes video streams, enhancing the functionality of connected third-party IP cameras. Similar to Ajax cameras, users can define custom detection zones to ensure recording is triggered only when movement occurs in selected areas. This reduces the volume of irrelevant footage, conserves HDD space, and makes archive searches more efficient.

Privacy comes first

Ajax video devices are designed with a strong emphasis on user privacy. End users have full control over their video surveillance and define who can access live streams, archived recordings, and settings via Ajax apps. Even PROs can access NVR settings only temporarily — and strictly within the limits set by the system owner.

Permission management via Ajax apps

Cloud account is protected with biometric login or passcodes, two-factor authentication, and session control. These measures ensure that only authorized users can access the system and that every action is properly logged.

Data transmission is protected by JetSparrow — a proprietary technology by Ajax. It combines peer-to-peer architecture with TLS encryption and advanced routing algorithms. The technology ensures stable video transmission even in challenging network conditions. As a result, footage is delivered without latency or data loss.

All system data is securely stored within the European Union, in compliance with strict EU data protection regulations. Additionally, Ajax video devices meet NDAA requirements, with all components sourced exclusively from manufacturers approved by the U.S. government.

Connect to any system via ONVIF and RTSP

Ajax NVR devices support ONVIF (Profiles S, T, and M³) and RTSP protocols, enabling seamless integration with third-party systems as well as direct video and audio streaming. This makes Ajax video devices an excellent fit for retrofitting existing installations or integrating into large-scale systems without compromising performance or functionality. Even third-party IP cameras connected to Ajax NVRs benefit from these capabilities — gaining access to video scenarios, centralized management, and secure access through Ajax apps.

Key to the Ajax ecosystem

NVR HAC devices bring third-party cameras into the Ajax ecosystem, enabling them to respond to system events and participate in automation scenarios. Once connected, these cameras operate as part of a coordinated system — responding to alarms and events in sync with native Ajax devices.

For example, third-party cameras can be used to instantly verify alarms triggered by Ajax detectors. If motion is detected, cameras can start recording and provide valuable insight in real time, helping staff assess the situation without delay.

Additionally, third-party cameras connected via Ajax NVR can trigger system responses — such as activating sirens added to the hub.

Alarm and event notifications in Ajax apps can instantly redirect users to the corresponding recording, providing immediate access to relevant footage. Everything is configured and managed directly within the apps.

Robust hardware for professional surveillance

NVR HAC devices are designed to meet demanding security requirements in a variety of environments. They feature an HDMI output for direct monitor connection and two USB ports for peripherals such as a mouse, keyboard, or flash drive. The NVRs support⁴ a 3.5" SATA hard drive with up to 16 TB of storage capacity, making them suitable for extensive video archiving. To ensure stable operation with high-performance HDDs, the devices are equipped with an active cooling system.

The front panel features color LED indicators that provide at-a-glance visibility of system states, including power supply, internet connectivity, Ajax Cloud connection, etc. Brightness can be adjusted in the app to minimize distractions.

Seamless experience from installation to daily use

Like all Ajax products, NVR HAC devices are designed for simplicity and reliability at every stage — from installation to long-term maintenance.

Quick setup. With Ajax apps, installation takes minimal time and follows workflows already familiar to PROs from other Ajax products. Devices are added via QR code, and the complete set includes everything needed for setup.
Comprehensive system control. Ajax apps and the built-in VMS offer live view, event feed, archive access, and device management. Monitoring station operators can customize video wall layouts to oversee multiple zones simultaneously.
Smooth archive management. The archive search is synchronized with system events, enabling fast post-incident analysis. Footage is easy to find using filters and calendar view, and recordings can be exported to a flash drive directly from the NVR.
Maintenance made simple. The apps display real-time device statuses, allowing security professionals to monitor system health and change settings without visiting the site. Updates are delivered over the air via the cloud, and Ajax technical support team is available whenever assistance is required.

The Ajax video product portfolio continues to expand, offering versatile tools for a variety of installation options. The new NVR HAC devices embody the brand's core values: immediate response, user privacy, and system synergy. They complement the signature cloud-based Ajax experience with local video management — no internet connection required and no compromise on control. With full integration into the Ajax ecosystem, these products help users not only see threats, but also respond immediately.
