SKU CH-W2RA-PJGJF

A 3-megapixel network dome camera with a 3-9 mm lens, 3× optical zoom and H.264 compression operating from -40 °C to 50 °C

  • 3 MP resolution captures detailed surveillance footage
  • 3x optical zoom with 3-9 mm lens adjusts field of view
  • H.264 and Motion JPEG compression reduces bandwidth and storage needs
  • Operates from -40 °C to +50 °C for extreme environments
  • Low 2.28 W power draw minimises energy costs

Network dome camera with motorised zoom

The AV3256PMIR-S is a 3-megapixel network dome camera built for commercial and industrial surveillance. Its 3-to-9-millimetre varifocal lens provides 3x optical zoom, allowing installers to adjust the field of view remotely during commissioning. The unit operates on 208-to-230-volt AC power and draws 2.28 watts, making it suitable for permanent mounting on existing mains wiring. It is rated for temperatures from minus 40 to plus 50 degrees Celsius and humidity up to 90 percent.

Resolution, frame rate and compression headroom

At full 3-megapixel resolution the camera streams at 21 frames per second using H.264 or Motion JPEG compression. This frame rate is sufficient for general monitoring and forensic review but will not deliver smooth motion capture for fast-moving objects. The signal-to-noise ratio of 45 decibels provides acceptable low-light performance, yet scenes with very high contrast or near-dark areas may show visible grain. Bandwidth and storage needs scale with the chosen compression profile and scene complexity.

Network protocol limits

The camera supports RTSP, RTP over TCP or UDP, HTTP, DHCP and TFTP for integration with standard video management systems. Management interfaces include web, SNMP and Telnet, though Telnet transmits credentials in clear text and should be disabled on exposed networks. The operating range of minus 40 to plus 50 degrees Celsius covers most outdoor climates, but the 208-to-230-volt AC requirement limits deployment to sites with compatible mains supply. No Power-over-Ethernet option is provided.

Questions about this item

Will the 3-9 mm varifocal lens and 3× optical zoom integrate with my existing ONVIF NVR?

The camera streams H.264 or Motion JPEG over RTSP, RTP/TCP and RTP/UDP, which are the standard transports most ONVIF recorders expect.

How can I verify the 3 MP sensor is delivering 21 fps after installation?

Open the web interface or SNMP monitor and confirm the live view reports 21 fps at 3 MP with a signal-to-noise ratio near 45 dB.

Does the package include a 208–230 V AC power supply or must I source one separately?

The camera requires 208–230 V AC input; no power supply is included, so a compatible AC source must be provided on site.
