FAQ

FAQ - Practical Questions About Using the infrared Night Vision Camera


Q: How does the image quality perform at night in real use?

A:The camera works as a night vision infrared camera, equipped with powerful IR illumination that delivers clear images up to 200 meters (656 ft) at night. Even in total darkness, this camera with infrared night vision can capture details of people and vehicles, making it highly effective in unlit outdoor areas and wide open fields.


Q: Is the camera weatherproof enough for long-term outdoor use?

A: Yes. The housing is rated IP66 and comes with a mechanical wiper. It can operate stably in heavy rain, dust storms, or humid coastal environments, ensuring the night vision and infrared camera continues to deliver reliable images regardless of weather conditions.


Q: Is it compatible with common NVR or VMS platforms?

A: Yes. It supports ONVIF, RTSP, and GB28181 standards, ensuring seamless integration with most mainstream NVRs, VMS software, and third-party systems.


Q: Does the camera support intelligent features? How do they help in real projects?

A:Yes. It supports human/vehicle classification, perimeter intrusion detection, and auto-tracking. In projects such as pipeline protection, border defense, and forest monitoring, these smart functions reduce false alarms and maximize the value of this infrared night vision camera.


Q: Is remote operation convenient?

A: Yes. Users can easily control pan, tilt, zoom, and preset patrols through a PC client or mobile app. This makes the night vision and infrared camera especially suitable for unattended or remote monitoring applications.


Q: Can the camera operate in extremely cold regions (e.g., Northern Europe, Russia)?

A: Yes. The camera includes a built-in heater and can operate normally at –45 °C, making this infrared night vision camera reliable for extreme cold conditions in forests, seaports, or border regions.
