The Uniview UAC-B122-AF40LM is a 2MP (Megapixel) LightHunter HD IR Fixed Mini Bullet Analog Camera. This model is part of Uniview's Whale Series and is characterized by its superior low-light performance and integrated audio capabilities.
Key Features:
- 2MP High Quality Imaging: Delivers sharp and detailed video at 1080P (1920x1080) and 720P (1280x720) resolutions.
- LightHunter Technology: This is the most significant feature of this camera. LightHunter is Uniview's advanced technology designed to provide exceptional image quality in ultra-low light conditions. It enables the camera to capture:
- Vivid color images even in very dim lighting, often without the need for additional visible white light.
- Images with reduced noise and enhanced brightness, thanks to a high-sensitivity sensor (1/2.9" Progressive Scan CMOS) and a large aperture lens (F1.6).
- This is achieved through a combination of hardware design (like the sensor and lens) and Uniview's proprietary image processing (U-ISP).
- 40m IR Illumination: Equipped with two infrared (IR) illuminators, providing effective black and white night vision up to 40 meters (approximately 131 feet) in complete darkness. It also features "Smart IR" to prevent overexposure of objects closer to the camera.
- Built-in Microphone (Audio over Coax - AoC): The camera has an integrated microphone to capture audio, which can be transmitted over the same coaxial cable as the video signal. This feature simplifies wiring and is primarily supported in TVI and CVI analog formats.
- Multi-format Output (4-in-1): This camera is highly versatile, supporting four major analog video output formats: TVI, AHD, CVI, and CVBS. This ensures wide compatibility with various existing analog DVR/XVR systems, making it suitable for both new installations and upgrades.
- 4.0mm Fixed Lens: Provides a horizontal angle of view of approximately 83.8°. This focal length offers a more focused or "zoomed-in" view compared to a 2.8mm lens, making it suitable for monitoring specific areas like entrances, pathways, or narrower fields of view. (A 2.8mm lens version, UAC-B122-AF28LM, is also available for wider coverage).
- OSD (On-Screen Display) Configuration Menu: An intuitive menu, available in 11 languages, allows users to easily adjust camera settings directly via the DVR/XVR interface.
- Robust and Durable "Bullet" Design:
- IP67 Waterproof and Dustproof: Ensures reliable operation in various outdoor environments, protected against dust ingress and temporary immersion in water.
- 4KV Surge Protection: Protects the camera from electrical surges and lightning strikes, enhancing its lifespan.
- Material: Constructed with a combination of metal and plastic, offering good durability for outdoor applications.
- Bullet Camera Form Factor: Characterized by its cylindrical shape, which is often chosen for its visible deterrent effect and ease of aiming at specific long-range targets.
- Image Enhancement Features:
- DWDR (Digital Wide Dynamic Range): Helps balance exposure in scenes with both very bright and very dark areas, ensuring details are visible in both.
- BLC (Backlight Compensation) and HLC (Highlight Compensation): Adjusts exposure to improve clarity when the subject is backlit or when there are intense bright lights in the scene.
- 2D/3D Digital Noise Reduction (DNR): Reduces image noise, especially in low-light, for cleaner and sharper video footage.
- Digital Defog: Improves image clarity in foggy or hazy conditions.
- Flip Function: Supports 180° horizontal and 180° vertical image flip for flexible mounting options.
The main difference between the UAC-B122-AF40LM (Bullet) and UAC-T122-AF28LM (Turret) lies in their physical form factor and the included lens:
Form Factor:
- Bullet cameras (B122): Cylindrical, often more visibly recognized as security cameras, and generally designed to be mounted on walls or ceilings for a fixed, often longer-range, view.
- Turret cameras (T122): "Eyeball" or "dome-like" shape (without a clear dome cover), offering a flexible ball-and-socket design for easy adjustment of the lens direction after mounting. They are less prone to IR reflection/glare than traditional dome cameras.
Lens: The -B122-AF40LM has a 4.0mm lens (narrower field of view), while the -T122-AF28LM has a 2.8mm lens (wider field of view).
