Overview of the i-PRO WV-S2231L

This product is now discontinued. Its replacement is the i-PRO WV-S2236LA.

This i-PRO dome IP camera delivers smooth HD 1080p resolution video at up to 60 frames per second (fps), complete with true day/night recording and infrared (IR) illumination of up to 30m. The unit features a vandal-resistant, IK10-rated housing to provide robust protection in exposed indoor areas and can be easily installed via Power-over-Ethernet (PoE).

A varifocal lens provides wide horizontal views (up to 110°) and allows the desired viewing angle to be easily set during installation. Handy 3.6x optical zooming is also available for real-time investigation into specific areas of interest.

Advanced imaging technologies such as Extreme Super Dynamic and Adaptive Black Stretch (ABS) help the camera deliver clear video footage in difficult lighting conditions. Intelligent Auto (iA) mode monitors scene dynamics and motion, then automatically adjusts key camera settings in real-time to reduce image distortion such as motion blur in busy locations.

Up to 4 video motion detection areas can be configured to help provide reliable security monitoring. When motion is detected, these alarms can also trigger specific tasks such as email notifications or recording to the onboard SD card. The camera’s integrated alarm and audio I/O ports allow the connection of external devices that can enhance alarm signalling or enable features such as two-way audio.

Variable Image Quality on Specified Area (VIQS) technology allows eight designated areas of the image to retain higher image quality whilst all other areas are streamed in lower quality. This technique helps to reduce image file size and bit rate. In addition, PoE supplies power and network connection to the camera through one cable - simplifying installation.

Please note: this camera does not come with a power supply, if required please select from below.

Key features & benefits

  • Capable of delivering smooth HD 1080p resolution at up to 60 frames per second (fps)
  • True day/night functionality with IR cut-filter provides round-the-clock surveillance of indoor areas
  • Integrated IR LEDs illuminate up to 30m, enhancing night vision
  • IK10-rated housing offers robust protection in locations where camera tampering may occur
  • Varifocal lens offers wide horizontal views of up to 110° for optimum scene coverage
  • 3.6x optical zoom allows real-time investigation into regions of interest
  • Image processing technologies such as Extreme Super Dynamic and ABS improve image clarity in challenging lighting conditions
  • Built-in video motion detection with 4 configurable detection areas helps to provide reliable security monitoring
  • H.265 compression format is supported - offering further reductions on bandwidth and storage over H.264
  • Two-way audio is supported with the connection of a microphone and speaker (not included)
  • Alarm signalling is enhanced when external alarm sources are connected via I/O ports
  • VIQS lowers the recording quality of non-essential areas to reduce bandwidth use and storage requirements
  • SD card storage provides a data backup if the network fails and allows the unit to be used in a stand-alone setup
  • PoE supplies power and network connection to the camera through one cable - simplifying installation

Compatible recording platforms
