Overview, Performance & Features – Dahua CCTV Camera Sri Lanka

The Dahua DH-HAC-B4A21P-VF 2 MP Varifocal Bullet CCTV Camera provides a balance of clarity, flexibility, and durability for reliable video security. Designed for both indoor and outdoor use across homes, offices, and retail spaces in Sri Lanka, this camera ensures high-definition 1080 p footage at 30 frames per second.

Featuring a 2.7–12 mm varifocal lens, it allows users to adjust the viewing angle manually. As a result, wide-area coverage or precise close-up focus becomes easy to achieve. In addition, the Smart IR technology intelligently controls infrared light, preventing over-exposure and maintaining clear nighttime images up to 40 meters.

Because it supports multiple video formats (CVI, AHD, TVI, and CVBS), integration with different recorders is effortless. Moreover, the IP67 metal housing resists dust and rain, offering long-term protection in tropical weather. Powered by 12 V DC, it consumes low energy while operating reliably through hot days and humid nights.

When combined with a compatible Dahua digital video recorder, users gain advanced playback, motion detection, and instant alerts—features that make the system ideal for modern security setups. The simple installation design reduces setup time, and ongoing maintenance is minimal.
