Smart dual light
The camera uses infrared night vision, and when an object is detected, it automatically turns on white light and takes full-color images. When the target disappears from the field of view, it returns to IR mode, which reduces light pollution and saves power.
AI SSA (intelligent scene adaptation)
Dahua AI SSA technology uses deep learning algorithms to recognize environmental conditions such as rain, fog, reversing light, low light or flickering. Based on this, it automatically adjusts the image parameters to ensure a clear and legible image at all times. image.
Perimeter protection
Thanks to artificial intelligence algorithms, the camera accurately recognizes people and vehicles. In restricted areas (for example, pedestrians or vehicles only), the number of false alarms in the event of features such as tripping or intrusion is significantly reduced.
SMD 4.0 (intelligent motion detection)
SMD 4.0 technology classifies objects that trigger motion alarms, eliminating false alarms caused by animals, for example. Combined with AI NVR, the “Quick Pick” function allows you to quickly search for recordings of people or vehicles, prioritizing the most relevant results.
Smart H.265+ and Smart H.264+
With the advanced adaptive algorithm, Dahua coding technology provides higher efficiency than standard H.265 and H.264. It ensures high image quality while reducing bandwidth and disk space consumption.
Outdoor resistance (IP67, wide voltage range)
IP67: The camera has passed rigorous dust and water resistance tests - it can operate normally after being submerged to a depth of 1 m for 30 minutes.
Wide voltage range: The camera tolerates voltage deviations of up to ±30%, making it suitable for outdoor installation in areas with unstable power supply.
Cybersecurity
Dahua network cameras are equipped with multiple security features: authentication, authorization, access control, encrypted transmission and data storage. These solutions effectively protect the device from external attacks and malware.
Dahua mobile app: DMSS
DMSS is a mobile surveillance app with functions such as remote monitoring, video playback, push notifications, device initialization and remote configuration. You can add devices such as IPC, NVR, XVR, VTO, doorbells, alarm hubs and access controllers. After logging in to your account, you can use cloud services such as upgrading to cloud service, etc. The app supports iOS 9.0 and Android 5.0 or above, and can be used with 3G/4G/Wi-Fi.
DMSS mobile app
A specialized app for operating Dahua devices on mobile devices.
The app allows you to remotely view and play back recorded images with a selected Dahua device. The app is available in Polish.
