Featuring the new Ambarella chipset and in-house ISP technology, this new series of cameras manages to encode @1080p with a bitrate of 2M and @720p with 1M, which is 75% saving on networking bandwidth and storage compared with many existing products. In addition, the new chip features improved design for power control comsuming 50% less than the previous generation of cameras and extending product life significantly.

The Eco-Savvy series provides crystal clear images with improved colour reproduction and more detailed images, motion deblurring and superb night visual effects. The series is also coupled with 3D-NR technology, which helps to eliminate image noise in low-light conditions without creating ghosting and blurring; and Dahua's patented Smart IR technology makes night time visual effects even better.

This series of cameras is designed for a more stable and efficient performance with stronger networking connectivity. With refined software, the system solution supports a maximum of 20-user visits and 6 users at 1080P previewing simultaneously. It ensures no packet loss for up to 100-metres of networking transmission. In addition, dual storage backup ensures system stability.
