Ajax DomeCam Mini HL 5MP 4mm Black

Ajax DomeCam Mini HL 5MP 4mm Black

The Ajax DomeCam Mini HL is a wired AI-powered IP security camera designed for professional indoor and outdoor video surveillance. This 5 MP version combines a 4 mm fixed lens with an 85° nominal viewing angle, hybrid illumination, True WDR, intelligent object recognition, and integrated audio recording.

Hybrid illumination allows the camera to use infrared or white light according to the configured conditions. This provides detailed surveillance in low-light environments while enabling full-colour footage when white light illumination is activated.

AI-Powered Video Detection

Built-in intelligent video analytics allow the camera to distinguish important objects and events from general movement.

AI object detection supports:

• People
• Pets
• Vehicles

Motion detection operates through software analysis of video frames. Users can also configure specific motion detection areas to focus surveillance on relevant parts of the scene.

AI processing takes place directly on the camera, helping reduce unnecessary recordings while making important events easier to locate.

Hybrid Illumination and Low-Light Performance

The Ajax DomeCam Mini HL combines infrared and white light illumination to maintain visibility in low-light and night-time conditions.

• IR illumination: up to 15 m
• White light illumination: up to 15 m
• Minimum colour illumination: 0.005 lx
• Minimum B/W illumination: 0 lx

Intelligent lighting control automatically adjusts the intensity of the LEDs to help prevent overexposure when objects appear at different distances.

White light illumination can provide full-colour footage at night, helping distinguish details such as clothing and vehicle colours. It can also provide a visible deterrent when activated.

5 MP Video and True WDR

The 5 MP CMOS sensor delivers detailed surveillance footage at resolutions up to 2880 × 1620 pixels.

Supported resolutions:

• 5 MP: 2880 × 1620
• 4 MP: 2560 × 1440
• 3 MP: 2304 × 1296
• 2 MP: 1920 × 1080
• 0.6 MP: 1024 × 576

The camera records at up to 25 fps and supports H.265 and H.264 video compression.

Its 120 dB True WDR technology balances areas with different lighting levels to retain useful detail in bright and dark portions of the same scene.

Lens and Viewing Area

The fixed 4 mm lens provides focused surveillance suitable for areas where a narrower field of view is preferred over the wider coverage provided by the 2.8 mm model.

• Focal length: 4 mm
• Maximum aperture: f/1.6
• Lens iris: Fixed
• Lens type: Fixed
• Horizontal field of view: 75–85°
• Vertical field of view: 40–50°
• Diagonal field of view: 105–115°

DORI distances:

• Detection: 86 m
• Observation: 34.4 m
• Recognition: 17.2 m
• Identification: 8.6 m

Built-In Audio

A built-in digital microphone allows the camera to record audio at the surveillance location when the appropriate settings are enabled.

Supported audio codecs:

• G711-ULAW
• G711-ALAW
• G726
• G722

Video Storage

Recordings can be stored locally on a compatible microSD card or integrated with an Ajax NVR.

The camera supports:

• microSD cards up to 256 GB
• Class V30 or faster memory cards
• Ajax NVR storage

The microSD card is not included in the complete set.

Network and Video Integration

The camera connects through a self-adaptive 10/100 Mbps RJ-45 Ethernet interface.

Supported network protocols include:

• HTTP
• HTTPS
• TCP/IP
• IPv4
• RTSP
• UDP
• DHCP
• DNS

The camera conforms with ONVIF® Profile S and supports RTSP, allowing integration with compatible third-party video surveillance and video management systems.

Ajax’s proprietary JetSparrow protocol provides fast, encrypted peer-to-peer video transmission and supports responsive live viewing and archive navigation.

Security Protection and Privacy

Multiple security technologies protect camera communications, firmware, and access to surveillance footage.

Protection features include:

• mTLS encrypted connections
• Authentication through Ajax Cloud
• Secure Boot protection against firmware spoofing
• OTA signature verification for secure firmware updates
• Configurable user permissions
• Two-factor authentication
• Session control
• Password or biometric account login
• Configurable privacy zones

Passwordless camera authentication reduces risks associated with default or compromised camera passwords.

Ajax System Integration

The camera can operate as part of an integrated Ajax security system alongside intrusion protection, video surveillance, fire and life safety, and automation devices.

Ajax scenarios can configure selected cameras to start recording when compatible Ajax detectors trigger an alarm. This provides immediate visual verification of security events.

The system can also be configured to activate compatible Ajax sirens when the camera detects motion or an AI-recognised object.
