Dahua DH-HAC-B1A51P 5MP HDCVI IR Bullet Camera

Dahua DH-HAC-B1A51P 5MP HDCVI IR Bullet Camera

4 Signals over 1 Coaxial Cable

HDCVI technology supports 4 signals to be transmitted over 1 coaxial cable simultaneously, i.e. video, audio*, data and power. Dual-way data transmission allows the HDCVI camera to interact with the HCVR, such as sending a control signal or triggering the alarm. Moreover, HDCVI technology supports PoC for construction flexibility.

Broadcast-quality Audio

Audio information is used as supplementary evidence in video surveillance applications. The HDCVI camera supports audio signal transmission over a coaxial cable. In addition, it adopts unique audio processing and transmission technology that best restores source audio and eliminates noise, guaranteeing the quality and effectiveness of collected audio information.

Long Distance Transmission

HDCVI technology guarantees real-time transmission at long distances without any loss. It supports up to 700m for 5MP HD video via coaxial cable and up to 300m via UTP cable.

Simplicity

HDCVI technology inherits the born feature of simplicity from the traditional analogue surveillance system, making itself the best choice for investment protection. HDCVI system can seamlessly upgrade the traditional analogue system without replacing existing coaxial cabling. The plug-and-play approach enables high-definition video surveillance without the hassle of configuring a network. 

Smart Illumination

The camera is designed with microcrystalline LED IR illumination for the best lowlight performance. Smart IR is a technology to ensure brightness uniformity in B/W images under low illumination. Dahua’s unique Smart IR adjusts to the intensity of the camera's infrared LEDs to compensate for the distance of an object and prevents IR LEDs from overexposing images as the object comes closer to the camera.

Multi-formats

The camera supports multiple video formats including HDCVI, CVBS and other two common HD analogue formats in the market. The four formats can be switched over through the OSD menu. This feature makes the camera to be compatible with not only XVRs but also most end users’ existing HD/SD DVRs.

Multi-language OSD

OSD menu provides multiple image adjustments and function settings to meet the requirements of different monitoring scenes. The OSD menu includes configurations such as backlight mode, day/night, white balance, privacy mask and motion detection. The camera supports 11 languages for the OSD menu, namely, Chinese, English, French, German, Spanish, Portuguese, Italian, Japanese, Korean, Russian and Polish.

Protection

IP67: The camera passes a series of strict test on dust and soak. It has a dust-proof function, and the enclosure can works normally after soaking in 1 m deep water for 30 minutes. Wide voltage: The camera allows ±30% (for some power supplies) input voltage tolerance (wide voltage range), and it is widely applied to the outdoor environments with instable voltage.
