The Dahua HAC-B1A51P 5MP HDCVI Fixed IR Bullet Camera is an HD analog surveillance camera for homes, shops, offices, warehouses and commercial properties. It combines detailed 5MP video, Smart IR night monitoring, multi-format output and IP67 weather protection in a compact bullet-style housing.
For buyers comparing the Dahua HAC-B1A51P price in Bangladesh, this model offers a practical way to upgrade a compatible coaxial CCTV system without changing to IP cameras. The current price at Touch IT is ৳1,950. Confirm the supplied lens, A51-S2 hardware version, XVR compatibility, stock and warranty before ordering.
The HAC-B1A51P transmits high-resolution video through coaxial cable to a compatible XVR. Its directional bullet design provides a visible security presence, while Smart IR supports continuous monitoring in darkness. Multi-format output also makes the camera suitable for supported new installations and analog-system upgrades.
The 5MP CMOS sensor captures video at a maximum resolution of 2880 × 1620. This provides more image detail than standard 1080p analog cameras and can improve general observation of entrances, vehicles and movement. Explore compatible recorders and cameras under CCTV Surveillance.
The A51-S2 version supports widescreen 5MP HDCVI video at up to 25 frames per second. When used with a compatible Dahua XVR, this provides detailed footage with smoother movement for everyday residential and commercial security monitoring.
The integrated infrared illuminator provides night coverage up to 20 metres. Smart IR manages illumination intensity automatically to help reduce overexposure when a person or object approaches the camera, producing more balanced black-and-white images in darkness.
Dahua lists a 3.6mm fixed lens as standard and a 2.8mm version as optional. The wider 2.8mm option provides approximately 106° horizontal coverage, while the 3.6mm lens offers an approximately 88° horizontal view. Browse more models on the Dahua CC Camera page.
One BNC port can output CVI, TVI, AHD or CVBS video. This flexibility allows the camera to operate with different supported analog recorders. The connected XVR must support the chosen signal format and resolution to provide the intended image quality.
DWDR, BLC and HLC help manage backlight, strong highlights and uneven exposure. Automatic gain control, 2D noise reduction, white-balance adjustment, mirror mode and privacy masking for up to eight rectangular areas provide additional installation control.
The IP67-rated plastic housing provides protection against dust and water when correctly installed. Its adjustable bracket supports pan, tilt and rotation for accurate positioning on walls, ceilings or suitable poles. Explore broader property protection options under Security System Solutions.
