Clear image with no blind spots
The 1/3.11" CMOS sensor works with a 2048×2048px resolution, providing crisp details in every shot. The fixed lens with a 0.98mm focal length and F2.2 aperture covers a 180°×180° field of view without any blind spots, which lets you monitor the entire space from floor to ceiling. Night monitoring is supported by an infrared illuminator with two IR LEDs with a range of up to 10m, which complements the night light for subtle entrance lighting.
Intelligent detection features
Integrated artificial intelligence algorithms recognise the presence of people and vehicles in the monitored area, which reduces the number of false alarms. The loitering function alerts you to people remaining in the detection zone for a set period. The system also registers when a parcel is left or taken from the door and sends instant notifications to your mobile phone when it wakes from sleep mode.
Wireless connection and management
Connection to the surrounding network is provided by Wi-Fi 6 technology on both 2.4GHz and 5GHz bands, which supports stable video signal transmission. The initial pairing with your mobile phone is facilitated by the Bluetooth interface. The entire system is managed and configured via the DMSS mobile app for Android and iOS operating systems, which is available in Czech, Slovak and English.
Power options
Power is supplied by one integrated 10000mAh (36Wh) battery, which lasts up to 150 days depending on the frequency of detections. Charging is done via the USB-C connector. Alternatively, you can use an external 5V power source via the USB port or connect a terminal block with a 12V to 24V DC or AC power supply.
Two-way audio transmission
The built-in microphone and speaker provide clear voice transmission between the visitor and the owner using G.711a, G.711Mu or PCM encoding. When you are away, visitors can leave a voice or video message. The device supports efficient H.265 video compression with an adjustable data rate from 32 to 2048kbps to save storage space.
Durable construction
The IP65-certified outer shell resists dust and splashing water, ensuring reliable functionality in adverse weather. The device operates in a temperature range from -20 to +50°C, which enables year-round outdoor operation. The device stores recordings on a microSD card with a capacity of up to 512GB, and the doorbell communicates with a wireless chime on the 868–868.6MHz frequency with a range of up to 100m.
