High resolution and wide viewing angle
The 1/3" CMOS optical sensor records video in 2560×1440px resolution, which delivers a detailed depiction of the captured scene. The fixed lens with a 2.3mm focal length and F2.2 aperture offers a 120° horizontal and 66° vertical field of view. The wide-angle optics cover a large part of the monitored area in front of the entrance. An integrated automatic day/night switch alternates between colour and black-and-white modes depending on the ambient light intensity.
Night vision
The device also works reliably in complete darkness thanks to its integrated infrared illuminator. Night vision is provided by 2 IR LEDs, which reach up to 10m from the lens. The DWDR function balances dark and light areas in the shot, improving image clarity in backlit conditions. H.265 video compression significantly reduces storage capacity requirements and the load on the transmission network while maintaining high recording quality.
Intelligent detection and false alarm elimination
Integrated artificial intelligence analyses the image and detects the presence of people and vehicles. The system minimises false notifications triggered by, for example, the movement of animals or leaves in the wind. The passive IR motion detector supports setting up to 4 independent rectangular zones for monitoring. Abnormal sound detection instantly sends an alarm notification to the mobile app on a connected phone.
Stable connection
Wireless communication is handled by a Wi-Fi 6 network interface operating in the 2.4GHz band, supplemented by Bluetooth technology for easy pairing. Connection to mobile phones with Android and iOS operating systems is mediated by the DMSS app. Local storage of recorded footage takes place on a microSD memory card with a capacity of up to 256GB, which eliminates the need to pay regular fees for cloud services.
Two-way communication and sound features
The device's body contains a built-in microphone and speaker for direct communication with people at the door. The sound transmission uses G.711a, G.711Mu or PCM audio compression for clear voice transmission. Users can talk to visitors remotely via a paired smartphone. The security system sends real-time notifications directly to the mobile phone's display as soon as the button is pressed.
Durable all-weather construction
With compact dimensions of 135×45×24.2mm and a weight of 110g, the device has an IP65 rating. This specification confirms high resistance to dust ingress and splashing water from any direction. An operating temperature range of -20 to +55°C allows for trouble-free outdoor placement and year-round operation in demanding climatic conditions.
