Ajax DOME HL 5-4 (W) - 5 Megapixel Video Surveillance Dome 4mm Lens

Ajax DOME HL 5-4 (W) Dome Video Surveillance 5 Megapixel 4mm Lens

Optics and image quality

The 4mm fixed lens combined with a 1/2.8" CMOS sensor delivers a detailed image with a resolution of 5 megapixels, suitable for applications that require precise subject identification. The 85° horizontal, 46° vertical and 110° diagonal field of view effectively covers wide areas while maintaining a good pixel density on the scene. The frame rate of up to 25 fps ensures smooth motion reproduction, limiting motion blur and facilitating video analysis. The 0° or 180° image rotation function allows the orientation of the capture to be adjusted according to the position of the camera during installation, without loss of quality.

Night Vision & Lighting

The camera incorporates a dual lighting system with white and infrared LEDs, each with a range of up to 15 meters. IR LEDs allow discreet monitoring in dark environments without visible light pollution, while white LEDs ensure a full-color scene when active lighting is required. These capabilities are suitable for outdoor or indoor installations that require constant visibility, regardless of light conditions.

Image processing and video compression

True WDR improves the readability of scenes with high dynamic range, balancing very dark and bright areas to avoid silhouettes and critical overexposures, which are particularly useful in backlighting or at the entrance to buildings. Support for the H.265 and H.264 codecs helps optimize the video stream by reducing bandwidth and storage space requirements, while adapting to the constraints of existing network infrastructures. This compatibility ensures flexible integration with current recording and supervision systems.

Local storage and recording

The camera has a microSD card slot supporting capacities up to 256GB, allowing for local video recording. This feature provides redundancy in the event of a network connection loss or a centralized recorder failure, and also allows for stand-alone recording scenarios. Local storage management allows video evidence to be stored on-site, with a flexible retention period depending on the configured bitrate, resolution and codec chosen.

Audio and communication

A built-in digital microphone allows sound capture to complement video, for more contextual recording of events. Audio combined with the image facilitates incident analysis, situation monitoring and remote decision-making, especially in security, access control or surveillance environments in public and commercial areas.

Video analysis and smart features

Intelligent embedded video analytics include motion detection and AI object detection, helping to distinguish relevant events and reduce false alarms. Motion detection allows you to trigger recordings, notifications, or automation scenarios as needed. Artificial intelligence object detection improves the accuracy of analysis, especially in dynamic environments, by focusing processing on the truly significant elements of the scene.

Network connectivity

The camera is equipped with a 10/100 Mbps RJ-45 Ethernet port ensuring a stable network connection for the transmission of video streams and control data. PoE power compatibility via the 802.3at/af standard simplifies installation by allowing simultaneous transport of power and data over a single cable, reducing cabling and deployment costs. The available bandwidth is sufficient to transport high-resolution streams compressed in H.265 or H.264, even in multi-stream configuration.

Power and energy consumption

The device can be powered either via 802.3at/af-compliant PoE, with a maximum power consumption of 7.3W, or via an external 12V DC power supply ± 20% with a current of 1A and a maximum power consumption of 6.3W. This dual power option offers great flexibility for integration, both in new installations and on existing infrastructures. The low energy consumption allows for multiple monitoring points without oversizing power and backup equipment.

Security, protection and reliability

The camera has a high level of protection against logical sabotage thanks to mTLS support, authentication via Ajax Cloud, the Secure Boot mechanism and signature verification during OTA updates. These devices ensure the integrity of the firmware, the confidentiality of exchanges, and protection against unauthorized modifications. The IP65-certified housing provides protection against dust and water jets, allowing for safe outdoor use in a variety of weather conditions. The operating temperature range of -30 °C to 60 °C allows installation in environments with large temperature variations without deteriorating performance.

Dimensions, weight and mechanical integration

With dimensions of 11.4 cm x 11.4 cm x 6.7 cm and a weight of 430 g, the camera has a compact size suitable for discreet integration on walls, ceilings or poles. Its small footprint makes it easy to implement in constrained spaces while ensuring robust installation. The size-to-weight ratio allows for compatibility with a wide range of brackets and mounting accessories, simplifying the design of the video surveillance infrastructure.
