As mentioned, this mini speed dome series enjoys the three “lows" — low streaming, low consumption and ultra low-lux as it is based on the Ambarella platform. According to Dahua, from the test report, one can notice that the bit rate is less than 4Mb/s during encoding@1080p, and less than 2Mb/s@720p; meanwhile, its frame rate is up to 60fps@720p, making it easier to spot every move and detail of the object in high-speed motions. In addition, compared with previous camera generations, each camera from the new platform can save over 50kW/h energy annually.

The mini speed dome series employs an in-house block camera, which is of an all-in-one design, having video, audio, alarm, network and SD card interfaces embedded as a whole. In addition, this mini speed dome series is of stronger colour reproduction capability, which is even closer to the original; and as for the night vision effect, the company uses the word "revolutionary” as the image is engineered to be quite clear and sharp with less noise, no matter whether it is in colour or the B/W mode.

The mini speed dome series supports 12x optical zoom, its viewing angle ranges from 4.64 degrees to 51.3 degrees, managing to cover wider domains under surveillance. In addition the Smart eye achieves instant focus with zero latency, enabling quick responding and an improved intelligence function. The dome series also supports max 300°/s pan speed and PoE+ (IEEE 802.3at) and conforms to the ONVIF protocol.

Dahua SD40/42/42C212S-HN mini speed domes series is designed to be suitable for applications such as stations, airports, malls, hotels, boutiques etc. The series provides various installations options, such as wall-, pendant-, ceiling- as well as in-ceiling-mounting depending on actual needs.
