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 detailed and smooth images.
Starlight technology for low-light conditions
Starlight technology and F1.6 aperture enable high-quality colour images even in insufficient lighting. The minimum illumination in colour mode is 0.005 lx, and in black and white mode – 0.0005 lx.
25× optical zoom
The motorised 5–125 mm variable focal length lens provides 25× optical and 16× digital zoom. The camera allows monitoring of large areas and magnifying distant objects without losing essential image details.
Infrared illumination up to 100 m
Four built-in infrared illuminators provide visibility in complete darkness up to 100 m distance. Illumination can be controlled automatically, manually or according to the lens zoom level.
Fast and precise PTZ control
The camera provides continuous 360° horizontal rotation and vertical movement from −15° to +90° with automatic 180° flip. Manual horizontal movement speed reaches 200°/s, and preset position activation speed – 240°/s.
Automatic area patrol
300 preset camera positions, eight patrol sequences, five movement routes and five scan routes are available. After a power interruption, the camera automatically restores the previous operating mode.
WizSense perimeter protection
Deep machine learning algorithms enable the camera to accurately distinguish between people and vehicles. The camera supports virtual line and fence crossing, intrusion, loitering, rapid movement, parking and crowd gathering detection.
Abandoned and missing object detection
Smart video analytics can detect objects left in or missing from the monitored area. This allows the camera to be used in public places, warehouses, production areas and other high-security zones.
Face detection and attribute analysis
The camera supports face detection, tracking, image capture and optimisation. It can analyse gender, age, glasses, facial expression, masks and moustaches, as well as simultaneously capture images of multiple faces.
SMD 4.0 smart motion detection
SMD 4.0 technology improves the accuracy of people and vehicle detection and reduces false alarms caused by insignificant motion in the monitored area.
AcuPick fast object search
AcuPick technology combined with compatible recording device allows precise location of people and vehicles in live or saved video recordings.
Automatic target patrol
When a smart video analytics rule is activated, the camera can automatically rotate towards the target and start area patrol using preset positions.
Enhanced image processing
The camera supports backlight compensation, bright light compensation, wide dynamic range, electronic image stabilisation, electronic fog reduction and 2D and 3D noise reduction.
Efficient video compression
Smart H.265+ and Smart H.264+ technologies reduce network bandwidth and recording storage consumption while maintaining high image quality. The camera simultaneously supports three video streams.
Audio and alarm connections
The camera is equipped with one audio input, one audio output, two alarm inputs and one alarm output. In case of alarm, image capture, recording, email sending, preset position activation or patrol mode can be triggered.
Local and network recording storage
Video recordings can be saved to a microSD memory card with capacity up to 512 GB, as well as to FTP, SFTP and NAS network storage.
PoE+ and 12 V power supply
The camera can be powered by 12 V DC or PoE+ power supply in accordance with IEEE 802.3at standard. Maximum power consumption with illumination, alarm and PTZ movement enabled is 20 W.
Durable construction for outdoor conditions
IP66 protection rating protects the camera from dust and strong water jets. The camera is equipped with 6000 V protection against lightning, overvoltage and temporary voltage fluctuations and is designed for operation at temperatures from −40 °C to +70 °C.
