Dahua 5MP IR Mini Dome

SKU: DH-IPC-HDBW2531E-S-S2

Quick Overview

5MP, H.265, 2.8mm, 120dB WDR, 30m IR, SD

Dahua Part DH-IPC-HDBW2531E-S-S2

Fully Onvif compliant and can be used with a wide range of embedded NVR or PC based NVR recorders.   Included is an easy to use config tool allowing easy access to the camera on any network.

Starlight Technology

This camera features ultra low lux capability allowing the camera to stay in colour in very low light levels.  Once in black in white in pitch black conditios the IR and starlight sensor will product an extremely crisp and sharp black and white image.

IVS Advanced Features

Tripwire and region settings all built in.

H.265 Encoding

This camera is capable of encoding H.264 or H.265 streams.  H.265 encoding will use half of the bandwidth to that of H.264 meaning that is requires half the disk space and half of the network bandwidth for the same quailty image.   When recording H.265 the NVR must alos support it.   

P2P Connection

This camera feature the ability to be able to setup a direct connection without port forwarding. Simply enable the Easy4ip feature and use the Dahua app to scann the QR code and your done - instant remote access from anywhere.
