Description

IPC-HDW3841EM-AS-0280B

We present IPC-HDW3841EM-AS, an excellent choice for each supervision system. This advanced 8MP camera is equipped with a 1/2.8 "CMOS image converter, thanks to which it can record high -resolution images even in low light conditions. It also emits an image with a maximum resolution of 8MP (3840 × 2160) at 20 frames per second with enabled with the AI ​​and 8MP (3840 × 2160) function at 25/30 cages per second, when the AI ​​function is turned off.IPC-HDW3841EM-AS uses the H.265 codec, ensuring a high compression and low bitrate. It also has a built -in IR LED diode, whose maximum infrared distance is 30 m. Thanks to the ROI function, Smart H.264+/H.265+ and flexible coding, this camera is suitable for environments of different bandwidth and mass memory. It also provides a number of intelligent detection functions, such as Intrussion, Tripwire and more to adapt to each monitoring scene. Thanks to the rotation mode, WDR, 3D DNR, HLC, BLC and digital watermark, this camera is a great choice for any supervision system.

WDR - Extended dynamic range


The WDR function allows you to get a transparent and detailed image, thanks to the skilful leveling of both too bright and darkened fragments of the recording. Thanks to the WDR system, it is possible to maintain the readability of the entire monitoring in places with a varied lighting level of the observed scene.

BLC - Backlight compensation


The function allows you to eliminate the resulting effect when the camera is directed towards a strong light source, i.e. when the first plan becomes dark and not legible. Compensation consists in brightening the first plan, unfortunately also at the expense of the background, which also becomes brighter. Generally, the function improves image quality.
