Ajax DomeCam Mini HL 8MP 4mm Black

Ajax DomeCam Mini HL 8MP 4mm Black

The Ajax DomeCam Mini HL is a wired AI-powered security IP camera designed for high-resolution indoor and outdoor surveillance. Its 8MP CMOS image sensor delivers video up to 3840 × 2160, while the fixed 4mm lens provides a horizontal field of view from 75° to 85°.

Additionally, hybrid infrared and white light illumination helps maintain clear surveillance in low-light environments. True WDR, intelligent video analytics and encrypted Ajax video communication further support reliable professional monitoring.

8MP 4K Video

The camera uses an 8MP 1/2.7-inch CMOS image sensor.

Supported resolutions include:

• 8MP – 3840 × 2160
• 6MP – 3072 × 1728
• 5MP – 2944 × 1656
• 5MP – 2880 × 1620
• 5MP – 2592 × 1944
• 4MP – 2560 × 1440
• 3MP – 2304 × 1296
• 2MP – 1920 × 1080
• 0.6MP – 1024 × 576

The camera supports a frame rate of up to 20 fps.

Furthermore, image rotation can be configured to:

• 0°
• 180°

4mm Fixed Lens

The DomeCam Mini HL uses a fixed 4mm lens with a maximum aperture of f/1.6.

Field of view:

• Horizontal: 75°–85°
• Vertical: 40°–50°
• Diagonal: 105°–115°

Therefore, the 4mm lens provides a more focused surveillance view for entrances, corridors, gates, driveways and other areas where greater distance detail may be required.

DORI Distance

For the 8MP / 4mm configuration:

• Detection: Up to 117.5m
• Observation: Up to 47m
• Recognition: Up to 23.5m
• Identification: Up to 11.6m

These distances provide a useful reference when planning camera positioning for different surveillance objectives.

Hybrid Illumination

The DomeCam Mini HL combines infrared and white LED illumination.

Maximum illumination distance:

• White LED: Up to 15m
• IR LED: Up to 15m

Intelligent lighting control automatically adjusts the intensity of the infrared and white LEDs in real time.

As a result, the system helps prevent overexposure while maintaining visibility of objects positioned at different distances from the camera.

Low-Light Performance

Minimum illumination:

• Colour: 0.005 lx
• Black and White: 0 lx

The signal-to-noise ratio exceeds 52 dB.

Therefore, the camera can maintain useful image performance in demanding low-light surveillance environments.

True WDR Image Processing

The camera provides 120 dB True WDR.

True WDR helps balance areas of strong light and shadow within the same image. Consequently, important visual details can remain clearer around windows, entrances, doorways and other challenging lighting environments.

AI Object Detection

The camera performs motion detection through software analysis of the video frame.

Built-in AI can recognise:

• People
• Pets
• Vehicles

Therefore, the system can identify relevant objects and support more targeted surveillance event handling.

Ajax DomeCam Mini HL Video Transmission

The camera uses JetSparrow, Ajax Systems’ fast and encrypted peer-to-peer video protocol.

The camera also supports:

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

Furthermore, the camera conforms with ONVIF Profile S for supported integrations.

Visual Verification Of Ajax Alarms

Ajax allows installers to configure scenarios in which selected detectors trigger specific cameras to begin recording.

The recorded event then becomes available through compatible Ajax mobile or desktop monitoring applications.

As a result, users can quickly review video associated with an Ajax alarm event.

Video Storage

The camera supports:

• MicroSD storage
• Ajax NVR

MicroSD cards with capacities of up to 256GB are supported.

The memory card should be Class V30 or faster.

MicroSD card is not included.

Built-In Microphone

The camera includes a built-in microphone.

With the appropriate settings enabled, the camera can record audio at the monitored location.

Supported audio codecs include:

• G711-ULAW
• G711-ALAW
• G726
• G722

Privacy And Access Control

Ajax provides configurable privacy controls for video surveillance.

The device owner can manage access rights for:

• Ajax mobile app users
• Installers
• Monitoring company operators through Ajax PRO Desktop

Therefore, access to video streams, event history and camera settings can be limited to authorised users.

Sabotage And Data Protection

The camera includes several security mechanisms designed to protect communication and firmware integrity.

These include:

• mTLS encrypted communication
• Authentication through Ajax Cloud
• Secure Boot
• OTA signature verification

Together, these technologies help protect transmitted data and prevent unauthorised firmware modification.

Network Connectivity

The camera uses:

• Port: 1 × RJ-45
• Ethernet: 10/100 Mbps self-adaptive

Supported network protocols include:

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

Power Supply

The camera supports both PoE and external DC power.

PoE

• Standard: IEEE 802.3at/af
• Maximum consumption: Up to 8.2W
• Average consumption: Up to 7.7W

External Power

• 12V DC ±20%
• 1A
• Maximum consumption: Up to 7.0W
• Average consumption: Up to 6.6W

Therefore, installers can choose the most suitable power method for the network infrastructure.
