High-resolution 4 MP image
The camera is equipped with a 1/2.8 type CMOS image sensor and delivers video with a resolution of up to 2560 × 1440 pixels. The maximum frame rate reaches 25/30 frames per second, ensuring clear and smooth imaging of moving objects.
Starlight technology for low-light operation
Starlight technology and F1.8 aperture help capture detailed colour images even in insufficient lighting. Automatic day and night mode adapts the camera's operation to the surrounding environmental conditions.
4× optical zoom
The motorised 2.8–12 mm variable focal length lens provides 4× optical zoom. The viewing angle can be adjusted from 96.9° to 31.6° horizontally, allowing you to monitor a wide area or zoom in on distant objects.
Infrared illumination up to 20 m
Three built-in infrared illuminators provide visibility in complete darkness up to 20 m away. Smart IR function automatically adjusts the illumination intensity, reducing the formation of excessively lit objects.
Remote-controlled PTZ movement
The camera can be rotated horizontally from 0° to 355° and tilted vertically from 5° to 90°. It supports 300 preset positions, eight patrol sequences and automatic operation resumption after a power interruption.
WizSense intelligent object recognition
Deep learning algorithms enable the camera to distinguish between people and vehicles. Perimeter protection supports virtual line crossing, intrusion, fence crossing, loitering, rapid movement, parking, gathering and abandoned or missing object detection.
Face detection and image capture
The camera supports face detection, face image capture and image quality enhancement. Face cropping from the overall image and selection of the most suitable face capture are available.
People counting and queue management
The camera can count people crossing a defined line, detect the number of people in a specified area and perform queue management. It is possible to generate reports on people who have crossed the defined line.
SMD intelligent motion detection
SMD technology analyses moving objects and helps reduce false alarms caused by insignificant events. It improves the accuracy of detecting significant people and vehicle movement events.
120 dB wide dynamic range
The wide dynamic range helps preserve visible details simultaneously in very bright and dark image areas. The camera supports backlight compensation, bright light compensation, 2D and 3D noise reduction, electronic image stabilisation and fog reduction.
Efficient video compression
Smart H.265+ and Smart H.264+ technologies reduce the space required for video recording storage and network bandwidth consumption while maintaining high image quality. The camera simultaneously supports three video streams.
Wired and wireless network connection
The camera can be connected to the network using an RJ-45 connection or 2.4 GHz Wi-Fi. It supports IEEE 802.11b, IEEE 802.11g, IEEE 802.11n and IEEE 802.11ax wireless standards with data transmission speeds up to 229 Mbit/s.
Built-in microphone
The built-in microphone provides real-time sound recording. The camera is also equipped with an external audio input and audio output, allowing you to connect compatible audio devices.
Local and network recording storage
Video recordings can be saved to a microSD memory card with a capacity of up to 512 GB, as well as to FTP, SFTP and NAS network storage.
Durable construction for outdoor conditions
IP66 protection rating protects the camera from dust and powerful water jets, whilst IK08 class provides protection against mechanical impacts. The camera is designed to operate at temperatures from −30 °C to +60 °C.
