FAQ

FAQ - Common Questions About the Infrared Night Vision Camera


Q: What is the advantage of 44× optical zoom in real applications?

A: This infrared night vision camera is equipped with a 44× high-magnification optical lens (6.9–303 mm), allowing operators to clearly observe distant targets such as roads, pedestrian crossings, or public squares, while maintaining image clarity without digital distortion.


Q: What image enhancement technologies does it support for complex environments?

A:The night vision infrared camera integrates True WDR, 3D DNR, HLC, BLC, Electronic Image Stabilization (EIS), and Defog functions, ensuring high-quality images even under backlight, smog, or strong light interference.


Q: Does it support local recording? What is the SD card capacity?

A: Yes. This camera with infrared night vision includes a built-in SD card slot that supports up to 256 GB, enabling local recording on site or as a backup when the network connection is lost.


Q: What intelligent analysis functions are supported, and how do they help in projects?

A: The night vision and infrared camera supports human/vehicle classification, intrusion/exit detection, and auto-tracking. These smart functions are ideal for traffic intersections, courtyards, and perimeter security, helping reduce false alarms and improving response efficiency.


Q: Does it support remote access and mainstream integration protocols?

A:Yes. This infrared night vision camera supports H.264 / H.265 compression, ONVIF, and GB28181, along with SSL encryption, HTTPS, IEEE 802.1x, and IP filtering. It ensures secure remote access and seamless integration with mainstream NVR or VMS platforms.
