Dahua IP Camera IPC-HFW2841S-S-0280B
The Dahua IP camera IPC-HFW2841S-S-0280B is equipped with an 8MP 1/2.7 CMOS image sensor, which provides high resolution in low light conditions. It has a modern lens with a 2.8 mm motorized zoom and uses IR diodes (IR range up to 30 m) . The camera uses Smart H.265+ & Smart H.264+ encoding technology, which provides higher coding efficiency than H.265 and H.264, guarantees high-quality video and reduces storage and transmission costs.

The IPC-HFW2841S-S-0280B uses the Starlight technology, which was created for use in harsh environmental conditions, even with minimal lighting. In extreme low-light conditions, Starlight technology is able to provide a colorful image in almost total darkness.

The Dahua IPC-HFW2841S-S-0280B IP camera has been equipped with a number of key technological safeguards such as security authentication and authorization, access control, trusted protection, encrypted transmission and storage encryption, which improves its security and data protection, and prevents the invasion of malicious programs on device. The device meets the requirements of cyber security and privacy protection.

The Dahua IP Camera IPC-HFW2831S-S-0280B-S2 supports Micro SD card storage up to 256GB. The IPC-HFW2831S-S-0280B-S2 has an IP67 water and dust protection rating, making it suitable for indoor and outdoor applications.

Smart IR
Smart IR guarantees a clear and optimally lit image even in places with poor ambient lighting. This function allows you to automatically adjust the intensity of the infrared light. Thanks to this function, we can change the basic parameters of the image, such as contrast, exposure or brightness. The signal processor analyzes the image on an ongoing basis and immediately after detecting overexposure, it reduces the power of the infrared illuminator. Thus, the image becomes clearer and overexposure disappears.

BLC:
The BLC function allows you to eliminate the effect that occurs when the camera is directed towards a strong light source, ie when the foreground becomes dark and illegible. The compensation consists in brightening the foreground, unfortunately also at the expense of the background, which also becomes brighter. Generally, the function improves the image quality.

3D DNR:
3D DNR analyzes individual frames and analyzes the differences between successive video frames to adjust pixels and increase image fidelity. 3D-DNR technology can reduce noise to a greater extent, but its disadvantage is the tendency to blur moving objects. Its main application is in relation to static areas of the observed space.

HLC:
The HLC function detects image points that are strongly illuminated and then masks them for effective observation. The HLC mode is extremely useful when observing underground car parks. Allows you to read license plate numbers that are obscured by "bright spots" from the headlights.

WDR:
Wide Dynamic Range extended dynamic range. Allows you to expand the capabilities of the BLC rear light compensation system. Cameras with the WDR function are equally suitable for outdoor use as well as for indoor systems. They eliminate the problem of blinding the camera by a strong light source, eg in sunny places or when the camera is to monitor the room and is placed opposite the window. WDR equalizes the lighting, so it allows both brightening of dark elements and darkening of overly bright areas of the image.

Intelligent Video System(IVS):
Intelligent video analysis Intelligent Video Surveillance consists in processing the recorded image. The task of the IVS function is to detect events with predefined criteria. Appropriate configuration of the function from the recorder level allows for constant analysis of the recorded image and enables very quick capture of undesirable events. The functions include: detection of crossing a virtual line, detection of intrusion in the zone, detection of disappearance/appearance of objects, face detection, detection of camera position changes, detection of paint on the lens, and noise detection.
