Arecont Vision SurroundVideo Omni G5

Multi-sensor cameras make of lot of sense in a wide range of applications, and as infrastructure and video management solutions advance, the issues relating to bit rate and network load become less significant. Arecont Vision’s SurroundVideo range is now in its fifth generation, and the latest versions offer a high level of performance.

What is it?

The SurroundVideo G5 series of multi-sensor cameras from Arecont Vision each incorporate four discrete cameras which can deliver a single stitched and smoothed 180 degree image using all four sensors, or four independent video streams. The all-in-one units simplify installation whilst also providing a high degree of flexibility with regard to system set-up.

The G5 range has models delivering 5, 12 or 20 megapixels. There is a 12 megapixel model which also incorporates wide dynamic range, allowing deployment in areas with harsh and contrasting light levels.

The SurroundVideo G5 range is suited to outdoor applications. All of the cameras are rated to IP66 and IK10. They also have a quoted operating temperature of -40 degrees C to +50 degrees C with a heater (o degrees C without). The units support power of ethernet for ease of deployment.

What about video performance?

The 5MP model deliver 12 frames per second at maximum resolution, and the two 12MP models achieve 10 frames per second, again at maximum resolution. The 20MP model supports 7 frames per second when delivering a 10240 x 1920 stitched and smoothed 180 degree stream.

Sensitivity is quoted as 0.2 lux (0.3 lux for the 20MP model), and the cameras deliver H.264 and Motion-JPEG streams, with 21 quality settings to allow customisation for a range of applications and needs.

Other features include privacy masking and backlight compensation.

What about low light?

The 5 megapixel model in the SurroundVideo G5 range makes use of Arecont’s STELLAR technology. This low light technology combines noise reduction and enhanced colour imaging. STELLAR (spatio temporal low light architecture) enables the delivery of colour video in very low light conditions.

Making use of patented algorithms t0 reduce noise, motion blur, bit rate usage and storage requirements, it utilises custom designed lenses and IR-cut filters which have been optimised to specific frequencies.
