8-inch 4MP 37X IR Network Speed Dome Camera

FAQ-Common Questions About the Infrared Night Vision Camera

Q: What is the difference between the 4MP model and the 8MP version?

A：The 4MP model delivers excellent clarity with 37× optical zoom and 200m IR distance, while consuming less bandwidth and storage. It is the right choice for projects that require a balance of performance and cost-effectiveness.

Q: Why choose 4MP instead of a higher resolution camera?

A: In most monitoring scenarios, 4MP resolution is already sufficient for clear human and vehicle recognition. Compared with 8MP, a 4MP infrared night vision camera saves more on transmission and storage, reducing the load on NVRs and hard drives.

Q: Is this model suitable for large-scale multi-site projects?

A:Yes. It is very suitable for industrial parks, campuses, and city roads where a large number of cameras are deployed. A camera with infrared night vision at 4MP keeps image quality while lowering the overall project cost.

Q: If I upgrade to 8MP in the future, is it compatible?

A: Yes. Both 4MP and 8MP models support the same standards (ONVIF/GB28181), so they can work under the same NVR or VMS platform. Expansion or upgrade is seamless.

Q: What back-end devices does it work best with?

A: It is recommended to use with H.265-supported NVRs or VMS software such as Hikvision, Dahua, or other third-party platforms. For edge storage, the camera also supports SD cards for backup recording in case of network failure.
