DS-2CD2146G3-IPTRZS2UY is an IP dome camera from Hikvision, part of the EasyIP 4.0 series. The AcuSense 3.0 technology it utilises provides perimeter protection with filtering for human and vehicle objects, enabling even more effective elimination of false alarms and rapid detection of objects of interest. Thanks to the use of Audio 2.0 and a dual-microphone design that provides excellent noise reduction, the camera delivers superb audio quality across a range of application scenarios. The camera is fitted with a 1/3" Progressive Scan CMOS sensor with a resolution of 4 Mpix and a 2.8 mm – 4 mm varifocal lens, which provides the Point-to-Point Fixed Zoom function. This solution allows the user to select the appropriate focal length when configuring the device, enabling the viewing angle to be precisely adjusted to suit the specific characteristics of the monitored area. The 2.8 mm lens provides a wide field of view, whilst the 4 mm focal length allows for a narrower viewing angle and greater detail of the observed section of the scene. The PTRZ function allows for remote adjustment of the viewing direction and focal length, eliminating the need for manual camera adjustment during installation. The IR illuminator, with a range of up to 30 m, ensures clear visibility at night. Support for both older and the latest H.265(+) compression standards allows for extended recording retention times whilst maintaining excellent image quality and ensuring backwards compatibility. Additional features to enhance image quality, such as AGC, 3D-DNR, WDR (130 dB), BLC, HLC and built-in video analytics (VCA), based on a deep learning algorithm, enable the camera to be used for advanced projects. The camera can be powered conventionally via DC 12 V or via PoE (compliant with the 802.3at standard). PLEASE NOTE!

This series integrates the latest technologies, such as ColorVu 3.0, AcuSense 3.0 and Audio 2.0, which provide users with higher image quality, more precise threat detection and improved audio communication. Cameras in this series also feature improved corrosion resistance and more environmentally friendly packaging.AcuSense 3.0Hikvision AcuSense 3.0 is an advanced video surveillance technology that utilises deep learning algorithms to enhance security effectiveness. The system offers the AcuSearch function, which enables quick searches for specific events or objects in recordings, significantly streamlining the analysis of video footage. Thanks to its improved algorithms, AcuSense 3.0 accurately detects and classifies threats, effectively distinguishing between people and vehicles, which significantly reduces false alarms. Audio 2.0Audio 2.0 offers better sound reception and clearer speaker effects. The design with a dual directional microphone ensures excellent noise reduction, a clear voice and better overall sound quality. The integration of an intelligent PA speaker increases the sound range, amplifies the warning effect of alarms and facilitates more effective two-way voice communication. With Audio 2.0, cameras can therefore better adapt to larger and more complex scenarios where audio requirements are higher.Motion Detection 2.0 The motion detection has been enhanced with AcuSense technology, allowing events to be filtered for human and vehicle silhouettes. This improves the performance of the entire system and reduces the number of false alarms that reach the user. Once the filter is turned off, detection can continue as before, detecting all objects.The PTRZ function The camera is equipped with the PTRZ (Pan, Tilt, Rotate, Zoom) function, which allows remote adjustment of the lens position and focal length without having to open the housing. The transparent dome allows for convenient configuration of the camera’s settings, eliminating the need to dismantl
