| Revew | 4-Channel Hybrid Video Recorder DAHUA XVR5104HS-4KL-I3 1TBThe Dahua XVR5104HS-4KL-I3(1T) is a Penta-brid S-XVR recorder that ships with a 1TB SSD already installed. It accepts 4 analog cameras over HDCVI, AHD, TVI and CVBS at up to 4K, plus IP cameras: 4 dedicated IP channels and up to 8 in total when analog channels are switched to IP. According to the manufacturer, the SSD holds about 18 days of recording at default settings. As a WizSense model it runs 4-channel SMD Plus, perimeter protection with tripwire and intrusion detection, and 2-channel face recognition on the recorder itself. The SSD uses less power and handles vibration better than a hard drive, and saves you choosing and installing a disk. It has 4K HDMI and VGA outputs, two-way audio, RS-485 for PTZ control and mobile app access.
