exacqVision Load Testing With Megapixel IP Cameras

December 10th, 2007

We’re always testing the network loading and throughput on our exacqVision NVR servers. It is important that when large numbers of megapixel IP cameras are connected to either a single server or to an enterprise that we can maintain our specified throughput and frame rates. There are a variety of ways for testing, including virtual camera software, but nothing is more accurate in a real-world scenario than connecting actual cameras and running the servers in a worst-case scenario: continuous free-run at 100% motion on all cameras.

Last week, TJ and Matthew traveled to California to perform just such qualification and testing at the Arecont Vision headquarters. Using our stock exacqVision server, used in our rackmount NVR systems and rackmount Hybrid systems, Arecont furnished more than 64 megapixel cameras which TJ and Matthew connected to the server through standard NETGEAR Smart Switches. The cameras were primarily AV2100 2-Mpixel (1600×1200) IP cameras, but there were also a mixture of other cameras, including AV3100 3-Mpixel (2040×1530) cameras and AV8360 360-degree panoramic IP cameras.

Our real-world testing once again confirmed our virtual testing. The exacqVision system achieved expected frame rates and network throughput, while maintaining a low processor load. We were able to specifically and definitively qualify a number of pending installations in which large numbers of megapixel cameras have been specified by our resellers for use with our NVR video surveillance systems.

Our thanks to Arecont Vision for hosting us at their facility and for providing all of the cameras and lenses we used for testing. Below are some pictures from the testing.
