Two video surveillance channels in one camera
The camera combines an 8 MP panoramic channel with maximum resolution of 4096 × 1860 and a 4 MP rotatable PTZ detail channel with maximum resolution of 2560 × 1440. Both channels allow simultaneous recording of a wide area overview and detailed observation of a selected object.
180° panoramic overview
The image from the upper panoramic channel is combined into a unified 180° wide-angle view, reducing blind spots and allowing continuous monitoring of a wide area even when the PTZ channel is rotated towards another object.
25× optical zoom
The PTZ detail channel's motorised 5–125 mm lens provides 25× optical zoom and 16× digital zoom. The horizontal viewing angle is adjustable from 51.9° to 3°, allowing both overview of a larger area and detailed observation of distant objects.
Fast and precise PTZ control
The camera provides continuous 360° horizontal rotation and vertical tilt from −15° to +90° with automatic 180° image flip. Maximum rotation speed reaches 180° per second, and tilt speed reaches 90° per second.
Automatic object tracking
WizTracking, associated tracking and Auto Tracking 3.0 functions allow the panoramic channel to detect an object and automatically direct the PTZ channel towards it. The camera maintains a wide overview while following the target and recording a detailed trajectory of its movement.
Intelligent automatic patrol
Following a smart video analysis alarm, the camera can automatically activate up to five preset positions or begin scanning important areas. 300 positions, eight patrol routes, five motion patterns and five scanning modes are available.
Night vision up to 100 m
The panoramic channel provides infrared and white light illumination up to 30 m. The PTZ detail channel's infrared illumination distance reaches 100 m, and warm white light distance reaches 50 m. Illumination can be controlled automatically, manually or according to lens zoom.
Intelligent dual illumination
The camera can use infrared illumination for discreet black and white monitoring and, upon detection of a specific object, switch on white light to obtain a colour image of the event. This helps reduce unnecessary continuous light pollution.
Active deterrence
Upon detecting a security event, the camera can activate flashing red and blue light signals and sound alarm. 11 built-in sound signals are available and the option to import up to 10 custom notifications.
SMD 4.0 object classification
SMD 4.0 and deep machine learning algorithms help distinguish people and motor vehicles from other moving objects. This reduces the number of false alarm notifications caused by animals, rain, leaf movement and other insignificant events.
Comprehensive perimeter protection
The camera supports line crossing, intrusion zone, fence crossing, loitering, rapid movement, vehicle parking and crowd gathering detection. Abandoned and missing object detection and alarm association with PTZ tracking are also available.
AcuPick intelligent search
The AcuPick function in the panoramic channel, together with a compatible network video recorder, allows precise detection of people and motor vehicles in live and recorded video footage.
Quality image in complex lighting
The PTZ detail channel supports 120 dB wide dynamic range, electronic image stabilisation, 2D and 3D noise reduction, backlight compensation, bright light compensation and electronic fog reduction.
Efficient video compression
Smart H.265+, H.265, Smart H.264+, H.264 and MJPEG video compression technologies reduce network load and storage space required for recordings. Three video streams with frame rate up to 30 frames per second are available for each camera channel.
Audio and alarm connections
The camera is equipped with one audio input, one audio output, built-in speaker, two alarm inputs and one alarm output. Audio output and built-in speaker operate in mutually exclusive mode.
Recording storage up to 512 GB
Recordings can be saved to a microSD memory card with capacity up to 512 GB, FTP or SFTP server and network storage. The camera supports ONVIF profiles S, G, T and M, as well as CGI, SDK and P2P integration.
PoE+ power supply
PoE+ technology provides camera power and data transmission over a single Ethernet cable. The camera can also be operated with a 12 V DC power source.
Durable housing for outdoor use
IP66 protection rating protects the camera from dust and powerful water jets. The camera is equipped with 6000 V protection against lightning surges, overvoltage and temporary voltage fluctuations and is designed for operation at temperatures from −40 °C to +65 °C.
