Monitor your home or business with the 4-Channel 8MP NVR with 2TB HDD and 4 4MP Night Vision Mini Turret Cameras from Dahua Technology. The NVR enables you to record from and manage the four included network cameras. It comes with 2TB of preinstalled HDD storage that can be expanded up to 6TB if more is required.
The NVR uses H.265 and H.264 compression to keep file sizes manageable while maintaining recording and playback quality. Its interface includes RCA ports for two-way audio communication, as well as HDMI and VGA connections for video output.
Each of the four included 4MP mini turret cameras captures 2688 x 1520 resolution video at 20 fps in a 104 x 57° field of view using its 2.8mm fixed lens. Built-in IR LEDs provide a night vision range of up to 98′. Designed for outdoor use, the cameras are housed in IP67-rated weather-resistant enclosures.
System
Recording options and schedules can be set for each individual camera or copied to all camerasIntelligent video analytics include tripwire violation detection, intrusion detection, abandoned object detection, missing object detection, face detection, tamper detection, and sudden scene change detectionONVIF compliant
