The Uniview UAC-T122-AF28LM is a 2MP (Megapixel) LightHunter HD IR Fixed Turret Analog Camera, part of Uniview's Whale Series. It's designed to deliver excellent image quality, particularly in low-light conditions, and includes a built-in microphone for audio surveillance.
Key Features:
- 2MP High-Quality Imaging: Provides clear and detailed video at 1080P (1920x1080) and 720P (1280x720) resolutions.
- LightHunter Technology: This is a core feature that distinguishes this camera. LightHunter is Uniview's advanced low-light technology, utilizing a highly sensitive sensor, a large aperture lens (F1.6), and sophisticated image processing (U-ISP) to:
- Capture vivid color images in extremely low light conditions, often without the need for visible white light illumination.
- Maintain clarity and reduce noise in challenging lighting.
- 40m IR Illumination: Equipped with two infrared (IR) illuminators, providing clear black and white night vision up to a distance of 40 meters (approximately 131 feet) in complete darkness. The camera uses "Smart IR" to prevent overexposure of closer objects.
- Built-in Microphone (with AoC - Audio over Coax): Allows for high-quality audio capture. The audio signal is transmitted over the same coaxial cable as the video, simplifying wiring. This feature is primarily supported in TVI and CVI analog formats.
- Multi-format Output (4-in-1): This camera is highly versatile as it supports four major analog video formats: TVI, AHD, CVI, and CVBS. This makes it compatible with a wide range of existing analog DVR/XVR systems, allowing for easy integration or upgrades.
- 2.8mm Fixed Lens: Provides a wide horizontal angle of view of approximately 101.5°. This is suitable for broad area coverage, such as a room, backyard, or parking lot. (A 4.0mm lens version, UAC-T122-AF40LM, is also available for a narrower, more zoomed-in view.)
- OSD (On-Screen Display) Configuration Menu: Offers an intuitive menu for adjusting camera settings directly via the DVR/XVR, available in 11 languages for user convenience.
- Robust and Durable Design:
- IP67 Waterproof and Dustproof: Ensures reliable operation in various outdoor environments, protected against dust ingress and immersion in water.
- 4KV Surge Protection: Provides protection against electrical surges and lightning strikes, enhancing the camera's longevity.
- Material: Constructed with a combination of metal and plastic for durability.
- 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 in challenging lighting conditions where strong backlighting or bright highlights might obscure details.
- 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 UAC-T122-AF28LM is an excellent choice for a wide range of surveillance applications, both indoors and outdoors, where high-quality video, superior low-light performance (including potential for color in very dim light), and audio capture are important.
It's a particularly good option for those looking to upgrade an existing analog CCTV system to HD with improved night vision and audio capabilities, without replacing the entire cabling infrastructure.
