Good day!

It is hard to tell but if possible, please help us run the following test：

1. Please go to www.speedtest.net to check your current download and upload speed and have you ever checked with the IP camera support to see if there is a speed required for live streaming?
2. What kind of software did you use on the computer, CMS5?
3. Is there any way connected to the Wi-Fi of the router, or via a long Ethernet cable to test If there is any delay on the main router?
4. By the way, how far away between the camera to the power-line adapters, like 20meters, or more?

And normally, live-streaming or notification detection from the cameras would be a few seconds left behind the real actions.

Thank you very much.

Thanks for your response

In answer to your questions

1  I tested my speed sometime ago and got 4.3 Mbs download, 7.6 Mbs upload which the camera supplier said is not great but OK

2 I am using free CMS software recommende by the camera supplier ( www. gardenature.co.uk). I dont know if it is CMS5

3 Today I  took the camera downstairs and used a 2m long ethernet cable to pug directly into the router without using the powerline adapters. The images stll showed a time delay of several seconds.

4. In the present test set up the camera is only 2 metre from the upstairs adapter and the downstairs adapter is about 2 metres from the router. If I ever get it working the camera will be about 30 metres from the powerline adapter.

What could be storing the images to produce the delay of several seconds ? The CMS software ? , the router? or could the camera itself have some memory ?
