As is mentioned, this mini speed dome series enjoys the three “Low”s — low streaming, low consumption and ultra low-lux as it is based on Ambarella platform. 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 the previous camera generations, each camera of the new platform can save over 50kW/h energy annually.
The mini speed dome series employs in-house block camera, which is of 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 color reproduction capability, which is even closer to the original; and as for the night vision effect, “revolutionary” should be the word as the image is quite clear and sharp with less noise, no matter in the color or the B/W mode. (Please refer to Photo 1 and Photo 2)
The mini speed dome series supports 12x optical zoom, its view angle ranges from 4.64 degrees to 51.3 degrees, managing to cover wider domains under surveillance. What worth a special mention is the “smart eye”, which realizes instant focus with zero latency, enabling quick responding and better intelligent
function(Photo3/4 shows its 12x optical zoom functionality in night view). The dome series also support max 300 °/s pan speed and PoE+ (IEEE 802.3at). All Dahua network products conform to ONVIF protocol.
Dahua SD40/42/42C212S-HN mini speed domes series is perfectly suitable for stations, airports, malls, hotels, boutiques and etc. The series provides various installations, such as wall-, pendant-, ceiling- as well as in-ceiling-mounting depending on actual needs.
