FAQ

FAQ – Long Range Security Camera Applications


Q: Is this product suitable as a long range security camera?

A: Yes. The ZN-LRS3785W2D-ES is designed as a long range security camera, featuring 37X optical zoom and powerful laser illumination. It enables clear identification of people, vehicles, and objects from1km kilometers away, even in low-light or complete darkness.


Q: How does this long range outdoor security camera perform at night?

A: This long range outdoor security camera uses advanced laser infrared technology with up to 1 km night vision range. It provides reliable long-distance monitoring in unlit areas such as borders, coastlines, ports, and wide open fields.


Q: Can this long range security camera withstand harsh outdoor conditions?

A: Absolutely. The housing is IP66/IK10 rated to resist heavy rain, dust storms, and strong winds. As a long range outdoor security camera, it also operates stably from –45°C to +60°C, making it suitable for deserts, coastal zones, and extreme cold regions.


Q: What projects benefit most from this long range outdoor security camera?

A:This model is ideal for border defense, coastal surveillance, forest fire prevention, oil and gas pipeline monitoring, and large-scale infrastructure projects. Its long range outdoor security camera capability allows wide-area coverage with fewer devices.


Q: Is this long range security camera easy to integrate with existing systems?

A: Yes. The ZN-LRS3785W2D-ES supports ONVIF, RTSP, and GB28181 protocols, ensuring seamless integration with most mainstream NVRs, VMS software, and third-party platforms. This makes deploying the long range security camera simple and cost-effective.
