[HELP] AVTECH issues

Hoping someone here has experience with AVTECH kit and can shed some light on the below:

We have an AVH321P NVR and 6x AVM459B cameras on the network. After a restart, the cameras will work for 2-3 days before we loose the feed to the NVR and can no longer access the HTTPS config page of each camera ... however they do still reply to pings!

1. What did you restart, the cameras and/or the router/switch hub?

2. If after restarting the cameras the images comes back up, provided that we have RULED OUT any potential router/network switches failures, then you should do the following experiment:

2.1 Lower down the frame rate of each cameras, dont set them to real time, lower them to, like 6 fps, that way not to much stress is applied onto each cameras. See if they last more than the typical 2 days straight up operating.

2.2 alternatively, try enabling the camera's built in auto reboot to occur one at 2 AM every night, that way you will always be on a 1 day restart configuration and your cameras will be operating up to 1 days perpetually. - theoretically no more failures after 2.x days of up-time since the cameras will be restarting itself every night, there will always be a max of 1 days of straight up, up-time. Thats it, provided that such a feature exists on your camera's HTTPS configuration page.

Lets assume your router or network switch is the failure point:

1. Experiment by connecting the cameras to another router or switch hub.

2. Set static IP addresses for each cameras, dont use DHCP. If your router behind the IP cameras's gateway is 192.168.1.1 and the router's DHCP's pool is set to 192.168.1.100 ~ 192.168.1.150 like most linksys/CISCO routers, then set the NVR's IP address to 192.168.1.99 and then IP camera #1 to 192.168.1.98 and IP camera #2 192.168.1.97 and so on going backwards, or if you prefer to go foward instead, then start at, say 192.168.1.50 and then proceed forward. You will be setting static IP addresses outside the router's DHCP addressable pool (by the way the DHCP pool is configurable too in case if you want to adjust the pool higher or lower for your own IP addresses "aesthetic" purposes).

2.1 Having set static IP addresses to each IP cameras and including the NVR itself and these static IP addresses assigned by yourself being outside your router's DHCP pool, you should now wait a few days and see if your particular problem reproduces. If the problem reproduces try enabling the cameras to auto reboot once every night at 2 AM or anytime you like, if the problem went away, your IP cameras have trouble keeping multi days up-times.
