All,
We are running various tests with Axis cameras and two routerboards. Currently the tests consist of using the RB493 as the AP-Bridge with a single R52Hn card and a small 12 db yagi. Ports 2 - 9 are enslaved to port 2 and a software bridge is in place to link these ports to the WLAN interface. We have tested various configurations of assigning the bridge, the master switch and the WLAN port an address of 192.168.1.1/24. This unit is connected to an Axis PTZ Camera (megapixel) @ 192.168.1.100:8100. We have also run tests with both 802.11 b/g/n & NV2 protocols. We see much better throughput (with bandwidth tests on the routerboards) with NV2.
As the station we have a 411 board, same Wlan card and antenna. The ether and wlan are bridged and as above we have tried assigning different interfaces 192.168.1.11. This card is setup as a station-bridge with wds enabled and matched protocols based on the stage of our test. There is a fixed axis camera (megapixel) which is connected to the internal network on this side: [rb411]----[ether switch]-----[camera/ip power relay].
We have tested both indoors and outdoors and used various test tools to trying and solve our issues. Tests range anywhere from 30 feet apart indoors to 600 feet apart outdoors.
We are seeing very poor performance when video of the station-bridge (fixed camera) is monitored from the AP-Bridge, this is the primary direction video data will travel as the AP-Bridge holds the recording device and will eventually will be the gateway to the customers network. If you link to the station-bridge side and view the AP-Bridge (PTZ camera) the performance is much better. We are trying both MJPEG which has much higher bandwidth requirements as well as H.264 which is well within the performance range of this type of link. We see the link go up to 54 Meg but bi-directional bandwidth tests are variable and on the link in question don’t appear to get above burts of around 3 Meg.
We have tried to rule out issues with the link quality by peforming longer range outdoor tests, but maybe still issues here? Could we have a configuration issue with gateways, NAT or some routing loop? I would think these would be a non-issue on this type of setup. To confirm what should the cameras at each end be configured for in terms of gateway addresses? Does anyone have other recommendations they could share, I know folks are successful with the same or similar setups out there.
Any pointers would be helfpul!
Thank You,
Candersonmailbox
