With its compact form factor and advanced features, this camera is an excellent choice for a wide range of applications, from home security to commercial monitoring.
Crystal-Clear 1080p Resolution
Equipped with a high-quality 2MP CMOS sensor, the DH-HAC-T1A21N captures video in 1080p Full HD resolution at up to 30 frames per second. This ensures that every detail is crisp and clear, providing high-quality footage for monitoring and evidence gathering. The camera’s progressive scanning system and S/N ratio of >65 dB deliver a clean, sharp image with minimal noise.
Intelligent Night Vision with Smart IR
Even in low-light or complete darkness, the camera provides a clear picture thanks to its built-in IR illuminator with a distance of 20 meters (65.62 ft). The advanced Smart IR technology automatically adjusts the intensity of the infrared LEDs to prevent overexposure of objects that are close to the camera, ensuring brightness uniformity and a well-defined black-and-white image in all lighting conditions.
Versatile 4-in-1 Technology
The DH-HAC-T1A21N is a highly flexible security solution. Its video output is switchable between four formats: HDCVI, HDTVI, AHD, and CVBS. This means it can be seamlessly integrated into almost any existing analog surveillance system, saving you the cost and hassle of a full system replacement. The camera comes with a 3.6mm fixed lens, offering a wide 80° horizontal field of view, while optional 2.8mm and 6mm lenses are available for different surveillance needs.
Durable and Easy to Install
The camera’s plastic casing is built to withstand a wide range of environmental conditions, with an operating temperature range of –40 °C to +60 °C.
