8 MP high-resolution image
The camera is equipped with a 1/1.8-type CMOS image sensor and provides a maximum resolution of 3840 × 2160 pixels with a frame rate of up to 25/30 frames per second. Starlight technology, F1.6 aperture and high sensitivity ensure clear and detailed images even in low light conditions.
Motorised variable focal length lens
The motorised 2.7–12 mm lens allows remote adjustment of the viewing angle and zoom according to the observed area. The horizontal viewing angle is adjustable from 113° to 47°, the vertical angle from 60° to 26°, and the diagonal angle from 133° to 53°.
Infrared illumination up to 60 m
Four built-in infrared light-emitting diodes provide surveillance in complete darkness up to 60 m distance. Intelligent illumination control automatically adjusts the infrared light intensity, helping to prevent over-illuminated objects.
WizSense artificial intelligence technology
Deep machine learning algorithms enable the camera to accurately recognise and classify people and vehicles. Perimeter protection supports virtual line crossing and intrusion detection, reducing false alarms.
SMD 4.0 intelligent motion detection
SMD 4.0 technology analyses motion and filters out irrelevant objects, such as small and large animals. Using a compatible artificial intelligence network video recorder, the Quick Pick function allows you to quickly find people and vehicles in recorded video footage.
Automatic image adjustment
AI SSA technology automatically detects conditions such as rain, fog, backlighting, low light and flickering, then adjusts image parameters for clearer results. The camera also supports 120 dB wide dynamic range, electronic image stabilisation, fog reduction and three-dimensional noise reduction.
Efficient video compression
Smart H.265+, Smart H.264+, AI H.265 and AI H.264 encoding technologies reduce bandwidth consumption and storage space requirements while maintaining high image quality.
Built-in microphone and external connections
The built-in microphone provides real-time audio recording. The camera is equipped with external audio input, audio output, alarm input and alarm output.
Local and network data storage
The camera supports microSD memory cards with capacity up to 256 GB, as well as recording storage on FTP, SFTP and NAS network storage.
Durable metal housing
Metal housing with IP67 protection rating protects the camera from dust and water exposure. The camera is designed for operation in outdoor conditions at temperatures from −30 °C to +60 °C.
Flexible installation and power supply
The camera can be powered by 12 V DC or PoE power supply. The adjustable bracket allows the camera to rotate 360° and tilt up to 90°.
