High-Definition Clarity for Total Peace of Mind
Eliminate Blind Spots with 100° Wide-Angle Coverage
In urban environments and small offices, every inch of coverage matters. The Dahua DH-HAC-T1A21P features a 2.8mm wide-angle lens that delivers a massive 100° horizontal viewing angle . This allows you to monitor an entire room from one corner, reducing the number of cameras needed and lowering your total security investment while ensuring no detail goes unnoticed.
1080p Full HD Resolution: Evidence You Can Trust
Don't settle for grainy, low-quality footage when it matters most. This 2MP camera captures fluid 1080p video at 30fps, providing the forensic-level detail required to identify faces and recognize incidents . Powered by a high-sensitivity CMOS sensor, the DH-HAC-T1A21P ensures sharp images that serve as reliable evidence for insurance or legal claims .
Smart IR Night Vision: 25m Clarity in Total Darkness
Security shouldn't fail when the lights go out. Equipped with Smart IR technology, this camera provides uniform brightness in black-and-white images up to 25 meters (82 feet) away . The intelligent algorithm automatically adjusts the intensity of the infrared LEDs as objects move closer, preventing "white-out" overexposure of faces and ensuring clear identification even in pitch-black conditions.
4-in-1 Versatility: Compatible with Almost Any System
Whether you are using a modern Dahua XVR or a legacy analog DVR, the DH-HAC-T1A21P has you covered. It supports CVI, TVI, AHD, and CVBS video formats, which are easily switchable via a single BNC port. This makes it a perfect "drop-in" replacement for older cameras, allowing you to upgrade to HD quality without replacing your entire infrastructure .
Quick-Install Design & Rugged Reliability
Save time and labor costs with the Quick-to-install eyeball structure. Its 3-axis adjustment allows for effortless mounting on walls or ceilings, ensuring the perfect angle every time. Designed to operate in extreme temperatures from -40°C to +60°C, this camera is built to withstand unstable power supplies with a ±30% input voltage tolerance .
