What this product does

Dahua IPC-HDW4631C-A is a turret model mini dome POE outdoor camera similar model with Hikvision  ds-2cd2355 with 6mp high resolution @20 frame per second (fps), slightly higher resolution than Hikvision and Amcrest 5mp camera. 6mp resolution is rare resolution, generally the resolution is 5mp or jump to 8mp resolution IP cameras aka 4k or Ultra HD resolution cameras such as Hikvision 2cd2385 or Lorex 4k security camera.

H.265 support

6mp is high resolution that might cause your network over loaded when few cameras stream together at the same time to the NVR recording unit. So that’s why the camera is applied with H.265 compression technology to reduce the bandwidth requirement up to 60% more efficient than no compression data.

The NVR system should support the H.265 as well such as Amcrest and Hikvision 16 channel 4k NVR system.

Dahua IPC-HDW4631C supports either H.265 or H.264 compression format so does Hikvision, but Amcrest doesn’t support H.265.

Adjustable FOV

Generally cameras with fixed lens demonstrate a single field of view angle, Dahua comes with three adjustable angle of view, 110°/81°/55°. Of course it’s not like motorized optical zoom cameras which allows you customized the field of view by system such as Hikvision Ds-2cd2742fwd-Izs and Lorex Lnd3374 4k security cameras.

Night vision

All the three products support night vision with the same range of illumination up to 98 ft, around 30 meters long distance enough to cover in darkness.

Audio built-in

Dahua IPC-HDW4631C comes with built-in audio to allows you hear the voice in one way, no speaker for two way communication like those home indoor model cameras. The competing products both Hikvision and Amcrest do not come with built-in audio.
