Dahua DH-HAC-T1A21P-U-IL-A 2MP Camera
The Dahua DH-HAC-T1A21P-U-IL-A is a 2MP Smart Dual Light HDCVI fixed-focal eyeball camera designed for reliable day-and-night surveillance. It delivers Full HD 1920×1080 resolution and supports Smart Dual Light technology, combining infrared and warm illumination for clearer nighttime monitoring. With a 25-meter illumination range, built-in microphone, and support for CVI/CVBS/AHD/TVI video formats, it offers flexible and dependable security for homes, offices, shops, and other properties. Its quick-install eyeball design also makes installation convenient and efficient.
Smart Dual Light
With its smart dual light mechanism, the camera automatically turns on the white light when Perimeter Protection/SMD Plus function of AI XVR detects a target in the rule area to capture clear, vivid images. When the target leaves the rule area, the camera automatically switches over from the white light to the IR light to significantly reduce light pollution.
Easy Installation
HDCVI eyeball comes with a quick-to-install pedestal, which makes it easier to install than conventional eyeballs and reduces cost on time and labor.
Broadcast-quality Audio
Audio signal transmission over coaxial cables is supported by the HDCVI camera. It adopts a unique audio processing and transmission
technology that restores source audio and eliminates noise, ensuring the quality and reliability of the audio information that is collected. This becomes important for video surveillance applications that use audio information as a type of supplementary evidence. Cooper Series | DH-HAC-T1A21-U-IL-A
4 Signals over 1 Coaxial Cable
HDCVI technology supports 4 signals (video, audio*, data and power) which are simultaneously transmitted over a coaxial cable. Dual-way data transmission allows the HDCVI camera to interact with the XVR to perform various actions such as sending control signals and triggering alarms. HDCVI technology also supports PoC, which makes the camera easy and quick to install.
Long Distance Transmission
HDCVI technology provides long distance transmission in real time without transmission loss. It supports transmission distances up to 700m for 2-MP/5-MP/8-MP HD videos through coaxial cables, and up to 300m through UTP cables. The results were obtained and verified through rigorous testing in Dahua’s test laboratory.
Simplicity
HDCVI technology inherits the simplicity of traditional analog surveillance systems, making it a great mechanism for protecting your
valuables. HDCVI can be upgraded from the traditional analog system without replacing the existing coaxial cabling. Its plug and play design enables it to produce high-definition videos during surveillance without the hassle of configuring a network.
