Dahua Lite 4MP WDR Starlight Vari-focal IR Network Camera IPC-HDW2431TP-ZS-S2

This motorized varifocal Dahua IP camera comes with 2.7-13.5mm lens which can be used longer distance like a driveway or a gate. A fixed lens camera may not be able to get the better picture than this camera at a distance of 15-40 meters, even the resolution is higher than 4MP. 

With upgraded H.265 encoding technology, Dahua Lite series camera has efficient video encoding capacity, which saves bandwidth and storage space. This camera adopts the latest starlight technology and displays better colorful image in the environment of low illumination. It supports SD card storage, waterproof function, dust-proof function, complying to the standards of IP67.

Features:

Smart(H.265+ & H.264+):

Adopting advanced algorithm of auto stream control according to the environment, Dahua smart encoding technology realizes the higher efficiency than (H.265 & H.264 ), providing high-quality video, and reducing the cost of storage and transmission.

Wide dynamic range (WDR):

Dahua adopts advanced Wide Dynamic Range (WDR) technology. You can get clear details in the environment of strong brightness contrast. In high brightness and back-light environment, bright region and dark region with strong light source, you can also get clear images.

Starlight:
Dahua Starlight technology mainly applies to the environment of low illumination, and it can provide clear colorful video. Even in the environment of min. illumination, the technology can guarantee the good image effect.

Intelligent Video Analysis (IVS):
With advanced video algorithm, Dahua camera supports intelligent detection, such as tripwire and intrusion and so on.

Protection (IP67, wide voltage):
IP67: The camera passes a series of strict test on dust and soak. It has dust-proof function, and the enclosure can works normal after soaking in 1 m deep water for 30 minutes. Wide voltage: The camera allows ±30% input voltage tolerance (wide

voltage range), and it is widely applied to outdoor environment with instable voltage.
