Dahua Security Camera: 5MP Turret, Lite Series – DH-IPC-HDW2531EMP-AS-0280B-S2-AUS-BLK

Description

With upgraded H.265 encoding technology, the Dahua Security Camera: 5MP Turret, Lite Series -DH-IPC-HDW2531EMP-AS-0280B-S2-AUS-BLK has efficient video encoding capacity, which saves bandwidth and storage space. This camera adopts the latest starlight technology and displays better colourful images in an environment of low illumination. It supports SD card storage, waterproof function, dust-proof function, complying with the standards of IP67.

Through advanced video algorithms, Dahua’s Intelligent Video Surveillance (IVS) technology supports smart functions such as tripwire and intrusion detection.

Starlight technology generates clear images in near-complete darkness. A high-performing sensor and special algorithms work together to capture images in low-light and no-light environments.

More Info

Smart H.265+ & Smart H.264+

With an advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video and reduces the cost of storage and transmission.

Wide Dynamic Range

With advanced Wide Dynamic Range (WDR) technology, the Dahua network camera provides clear details in the environment of strong brightness contrast. The bright and dark areas can get clear video even in a high brightness environment or with a backlight shadow.

Starlight

With advanced image processing technology and optical technology, Dahua Starlight technology can provide clear colourful video in an environment of low illuminance. It widely applies to various environments of low illuminance.

Intelligent Video Surveillance

With an advanced video algorithm, Dahua IVS technology supports intelligent functions, such as tripwire and intrusion.

Durable IP67: The camera passes a series of strict tests on dust and soak. It has a 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% (for some power supplies) input voltage tolerance (wide voltage range), and it is widely applied to an outdoor environment with unstable voltage.
