CCTV camera Dahua DH-SD22404T-GN (PTZ 4x)

Thanks to powerful optical zoom and accurate zoom (pan / tilt), PTZ cameras of the SD22 series can provide detailed control over a small area. The camera is equipped with a matrix with a resolution of 4MP, and the possibility of recording 4M / 3M - 25 frames per second, 4-fold optical zoom. Among the characteristic features, we can emphasize fast and smooth control, high image quality and good protection, which makes it more suitable for the requirements of modern video surveillance systems.

Wide dynamic range

Built-in wide dynamic range (WDR) technology normalizes a bright picture, even in the most difficult lighting contrast conditions. For tasks with complex conditions of high and at the same time low light, hardware WDR (120dB) simultaneously optimizes bright and dark areas of the scene to ensure high image quality.

High-quality video encoding (H.265)

The H.265 video compression standard (ITU-T VCEG) provides twice the data compression ratio at the same video quality level, or significantly improved video quality at the same bit rate, compared to older video compression technologies. H.265 offers such compression by extending sample comparison and difference coding, improving motion vector prediction and motion domain fusion, and incorporating an additional filtering step called selective adaptive bias filtering.

Environmental

The camera is designed for extreme environmental temperatures, in the range from -40 ° C to + 60 ° C. The camera meets IP66, IK10 protection standards, which makes it able to withstand harsh environmental conditions.

Interoperability

The camera complies with ONVIF (Open Network Video Interface Forum) and PSIA (Physical Security Interoperability Alliance) standards. Ability to connect to network video devices regardless of the manufacturer.
