Dahua DH-HAC-B1A21P-A 2MP HDCVI IR Bullet Camera

The Dahua DH-HAC-B1A21P-A is a 2MP HDCVI IR bullet camera built for reliable outdoor surveillance where a longer, more visible camera body helps deter intruders. Smart IR technology reaches up to 20 meters, keeping gates, driveways, and perimeter walls clearly visible after dark.

This bullet camera supports CVI, CVBS, AHD, and TVI signals through a single BNC output, so it slots easily into most existing analog DVR systems without extra converters. The built-in microphone adds audio capture alongside crisp 1080p video, giving a fuller record of activity around your property.

With an IP67-rated housing and an operating range of -40°C to 60°C, the DH-HAC-B1A21P-A is built to withstand Bangladesh's heavy rain, humidity, and summer heat, making it well suited to outdoor mounting on walls, ceilings, or poles.
