Ajax NVR 8 HAC (B) - 8-channel recorder, up to 12MP

Ajax NVR 8 HAC(B) 8-channel recorder, up to 12MP

Video architecture and input capabilities

This video management device has 8 channels of video input, allowing the simultaneous connection of multiple cameras for extended coverage of a site. The installation is specifically designed for an indoor environment, in accordance with its IP20 protection rating which indicates protection against medium-sized solids without any particular resistance to humidity. This multi-channel architecture makes it a suitable solution for centralized video surveillance systems, with optimized management of multiple HD and megapixel streams.

Recording Resolutions and Compression Formats

The recorder supports a wide range of recording resolutions, including 12MP, 8MP, 6MP, 5MP, 4MP, 3MP, 1080p, UXGA, 720p, VGA, 4CIF, DCIF, 2CIF, CIF, and QCIF. This broad compatibility allows the level of detail to be precisely tailored to operational needs, from very high definition for fine identification to lower resolutions optimized for bandwidth and storage. Video streams are encoded in H.265 and H.264, which offer an excellent compromise between quality and file size, as well as the JetSparrow format for optimized integration into the manufacturer's ecosystem.

Video outputs and playback functions

The HDMI output supports resolutions of 1920 × 1080, 1600 × 1200, 1280 × 1024 and 1280 × 720 pixels, ensuring compatibility with the majority of professional monitors and control screens. The system allows synchronized playback on 8 channels, allowing multiple video streams to be reviewed simultaneously for quick analysis of events across the entire monitored site. This configuration makes it easier for control room operators to do their jobs, especially for verification, investigation and video auditing operations.

Intelligent video analysis and detection

The device incorporates intelligent video analytics features, including motion detection and AI object detection. These algorithms help reduce false alarms by focusing on relevant events, such as the appearance, movement, or disappearance of objects in the cameras' field of view. Intelligent analytics helps optimize proactive monitoring and automate alert generation, improving responsiveness in the event of an incident.

Recording capacity per channel

The processing capacity of the system is structured by resolution and number of channels: 1 channel can operate in 12MP, 1 channel in 8MP, 3 channels in 5MP, 4 channels in 4MP, 4 channels in 1080p, 8 channels in 720p and 8 channels in 1024 × 576 px. This distribution makes it possible to precisely size the camera fleet according to the high-criticality areas, which will benefit from the highest resolutions, and the secondary areas where a lower resolution is sufficient. This allows the administrator to balance processing and storage loads while preserving image quality in high-priority areas.

Data Storage and Management

The system has a built-in slot for 1 SATA hard drive, supporting a maximum capacity of 16 TB (drive not included). This large storage capacity allows you to maintain an extensive video history, even with high-resolution streams. The optimization provided by the H.265 and H.264 codecs, combined with the ability to adjust the resolution per channel, helps extend the retention time of recordings while maintaining usable quality. Hard drive management is supported by a built-in video management system, making it easy to configure recording schedules, retention policies, and sequence exports.

Network connectivity and supported protocols

The device is equipped with a 10/100 Mbps self-adaptive RJ-45 Ethernet port, ensuring simple integration into existing network infrastructures. The maximum bandwidth supported is 80 Mbps input and 40 Mbps output, allowing multiple HD streams to be managed simultaneously in real time, while maintaining headroom for remote access and multi-user viewing. The system supports a wide range of network protocols, including HTTP, HTTPS, TCP/IP, IPv4, IPv6, SNMP, RTSP, UDP, DHCP, DNS, and DDNS, ensuring flexibility to integrate into enterprise IT environments, with support for monitoring, streaming, and remote configuration.

Compatibility with third-party devices and systems

The device is designed to work seamlessly with Ajax cameras and IP cameras that support ONVIF S and T profiles, as well as RTSP streams. This compatibility ensures easy integration with a wide range of network cameras on the market. The integrated video management system allows for centralized management of equipment, from adding cameras to configuring recording and detection settings. It is also capable of performing visual verification of Ajax system alarms, adding a layer of video confirmation to security events to reduce unnecessary interventions and improve diagnostic accuracy.

Data Security and Privacy

The device incorporates privacy mechanisms, including support for secure protocols such as HTTPS, and advanced configuration options for access control. User rights management, video stream security, and compatibility with network standards make it possible to limit access to only authorized individuals and protect data from unauthorized interception. These features meet the requirements of business environments where the protection of visual information and event logs is critical.

Power supply, internal clock and conditions of use

The device operates on a 110 to 240 V, 50/60 Hz mains power supply, with a maximum consumption of 0.6 A and a power of up to 24 W. It is equipped with a CR2032 type clock battery, 3 V, ensuring that the system time is maintained in the event of a power failure, which guarantees the accuracy of the timestamps of the recordings. The operating temperature range extends from 0°C to 40°C, which covers the majority of standard indoor environments, such as offices, technical rooms and control rooms, without the need for specific air conditioning outside of normal operating conditions.

Dimensions, weight and physical integration

The chassis has dimensions of 21.2 cm x 21.2 cm x 6.4 cm and a weight of 782 g, which makes it easy to fit into tight spaces, on a desk, a technical shelf or in a control cabinet. Its compactness and low weight also simplify installation, maintenance and replacement operations. The IP20 rating confirms an inward-facing design that is suitable for the clean and dry environments typical of modern security infrastructures.
