D-Link, lacks serious!

The one I received (D-Link DCS-5020L purchased on 01/02/2015) disappointed me, she did not stop to reset without reason several times a day as soon as I get there, so I already have 4 other IP cameras of other brands which themselves run smoothly.

After a little research, I realized that his was 1.04b08 firmware release - the 10-03-2014 and the problem is that this version is buggy Harchi [...]
I therefore spent 1.05b08 version of 20-01-2015 and there, no problem, it finally works properly.

So CAUTION model comes with a faulty firmware !!!! A mandatory update.
