IP dome features WDR, low light sensitivity

IndigoVision's new IP dome is based on Pixim’s ‘Seawolf’ sensor.

IP video security solutions manufacturer IndigoVision has launched an IP dome based on Pixim’s ‘Seawolf’ sensor. Using progressive scan and Wide Dynamic Range (WDR) technologies, the new camera delivers outstanding picture quality, says the company, even in challenging lighting.

"Unlike CCD cameras, there is no trade-off between low-light performance and WDR, as the advanced sensor technology allows individual pixels to dynamically adjust to lighting conditions," said a representative for the manufacturer.

This dome is part of IndigoVision’s end-to-end IP Video solution, with H.264 compression built-in. It delivers video at 4SIF 25/30 fps, with a guarantee that no frames will be dropped even in high-motion scenes. The camera's range includes standard internal, vandal resistant internal and vandal resistant external cameras, with ceiling and wall mounting options and standard or telephoto lenses.

IndigoVision’s analytics and Activity Controlled Framerate (ACF) run in real-time within the dome. Performing analytics at the edge removes bottlenecks and enables instant response, allowing operators to use what is known as ‘dark screen’ monitoring, where video is only displayed when an incident occurs. ACF controls the framerate of the video stream based on the amount of motion in the scene. When there is no activity, video is streamed at minimal bandwidth; the instant any motion is detected, video is simultaneously transmitted at maximum configured framerate. This significantly reduces the bandwidth and NVR storage requirement for cameras monitoring generally static scenes or during quiet periods such as at night and is unique to IndigoVision.

The dome also has dual encoding capabilities allowing up to six separate video streams to be transmitted over the network, with any combination of resolution and framerate. This is useful in distributed systems, where a high-resolution stream is recorded locally on a Network Video Recorder (NVR) and a lower-resolution second stream is transmitted across a wireless link or WAN to remote operators.

This dome has many additional features including Power-over-Ethernet (PoE) for lower installation costs, and built-in input/output (I/O) capability. Two opto-isolated inputs and an opto-isolated relay output allow external systems to be connected. The inputs can trigger events and alarms in ‘Control Center’, IndigoVision’s Video Management Software, and the output can be switched by automatically generated or operator controlled actions.
