Key Capabilities
Up to 8MP Turbo HD Recording
The DVR accepts compatible HDTVI camera signals up to 8MP and supports 8MP encoding at up to 8 fps on channel 1. Lower resolutions provide higher available frame rates, allowing the recording configuration to be balanced around image detail and motion requirements.
Motion Detection 2.0
Deep-learning-based Motion Detection 2.0 is enabled for the analogue channels and classifies human and vehicle targets. This can significantly reduce unwanted events generated by irrelevant movement such as leaves or changing lighting.
Analogue & IP Hybrid Expansion
Four analogue BNC inputs can operate alongside IP camera support. Standard operation supports additional IP channels, while Enhanced IP mode can expand the recorder to as many as eight IP channels with cameras up to 8MP resolution.
H.265 Pro+ Compression
H.265 Pro+ is designed to improve recording efficiency and reduce storage requirements compared with older video compression methods, helping make better use of the installed surveillance hard drive.
Audio Over Coax
Compatible Turbo HD cameras can carry audio over the same coaxial connection used for video. The recorder supports coaxial audio on up to four analogue channels, reducing the need for separate audio cabling in suitable installations.
Up to 10TB Internal Storage
One SATA interface supports a surveillance hard drive with capacity up to 10TB, allowing storage to be selected around the number of cameras, recording resolution, bitrate and required retention period.
