Face Detection

Dahua Face Detection technology can detect the face in the image. With deep learning algorithm, the technology supports detecting, tracking, capturing and selecting the best face image, and then outputs face snapshot.

Protection (IP66, TVS 6000 V)

IP66, TVS 6000 V lightning proof, surge protection, and voltage transientprotection.

PFA Technology

PFA technology has introduced new methods of judgment that ensure the accuracy and predictability of the direction of subject distance
adjustment. The result is a set of advanced focusing algorithms that ensure image clarity when zooming and that shorten focus time.
This makes the camera highly advanced in its functions, substantially improving the quality of your experience.

4G Transmission

4G Transmission The camera supports 4G signal transmission and the following network types: LTE/WCDMA/GSM. And it supports the following frequency band

respectively:

LTE-TDD: Dual-band Band 38/40
LTE-FDD: Eleven-band Band 1/2/3/4/5/7/8/28/12/17/66
WCDMA: Hexa-band Band1/2/3/4/5/8
GSM: Quad-band Band 1/3/5/8.

SMD

Empowered by Deep-Learning Algorithms, Dahua SMD filters out motion detection alarms triggered by targets that are not a concern.
It quickly recognizes humans and vehicles, triggering alarms when an intrusion occurs.
