Dahua 8ch DVR Penta-brid 4K 1U Digital Video Recorder

System Overview With the surveillance operators pursuing to HD/UHD which further adds the storage and transmission cost, HDCVI H.265 /H.265 has been released to incredibly decrease the required bitrate while ensuring the video quality in realizing high resolution surveillance such as 4MP/4K. Designed as a collection of intelligent encoding algorithm based on H.265, H.265 significantly improves encoding efficiency and save bandwidth/storage cost, which fully meet the needs of users facing budget constraints who both require quality and performance. Besides smart codec, the series supports various advanced functions like IoT and POS functionalities, making the whole system smarter and more convenient which is a perfect choice for mid to large-scale business and projects where both high reliability and flexibility are required. Functions Smart H.265 Smart Codec, H.265 can reduce up to 80% bit rate and storage requirements compared with H.264 without having to invest in new cameras. HDCVI/AHD/TVI/CVBS Auto-detect The XVR can auto recognize the signal of front-camera without any setting. It makes operation more friendly and convenient. 8MP Resolution The XVR supports up to 8MP HD resolution (3840 x 2160) HDCVI camera and IP camera input. Coaxial Audio/Upgrade/Alarm The integrated design can reduce wiring troubles which makes it much more cost-effective and convenient for installation. Long Distance Transmission The HDCVI system supports long distance transmission over coaxial cable and UTP, max. 700m for 4K/4MP, 800m for 1080P and 1200m for 720P. IoT Functionality HDCVI IoT can achieve multi-dimensional surveillance by integrating sensors with monitoring video, which not only can generate the report for analysis but also prevent risk in advance. POS Functionality This funcion includes POS ticket information overlay and search which can be widely used in retail programs. Smart Fan Design The smart fan can automatically turn on or turn off according to the CPU temperature. This function can effectively reduce the fan noise to provide a better user experience.
