Using the VideoEdge IP Encoder with Intellex IP

_______________________________________________________________________

Recommendations

• Limit the total encoder image rate to 240 4CIF ips per system. This would

be 4 encoders at 15 ips per camera or two encoders at 30 ips.

• Try to balance resolutions, rates, and expected scene motion across the

encoders and Intellex IP units where possible.

• Enable security and log out of Intellex if local live surveillance is not

needed in order to reduce CPU load. Disconnecting the VGA monitor does

not drop the CPU load.

Performance on Legacy Intellex IP Platforms

Intellex IP was built on a Dell PowerEdge 750 server prior to July 2007. After July

2007, the platform is a Dell PowerEdge 860 server. The older server can be

upgraded to Intellex software version 4.12 but the performance will be limited

because of processor and motherboard limitations. Unfortunately, hardware

upgrades are not practical for the PowerEdge 750. In general, the CPU loading is

twice as high on the PowerEdge 750 compared to the PowerEdge 860 under the

same conditions of live rate, resolution, and record rate. The difference between

the PowerEdge 750 and 860 models is that the PowerEdge 750 has a floppy

drive in the right hand drive bay and a single USB connector in front, while the

PowerEdge 860 has no floppy drive and dual USB connectors in front.

Recommendations

• Limit upgraded PowerEdge 750 servers to two VideoEdge IP encoders per

server.

• Limit the encoder image rate (the live rate) to 15 ips per camera.
