CPCam 517HC (AVTech) loses network connectivity

[Scruit 0]

I use the FTP function built into the CPCam 517HC to ftp images of motion to my PC. Every couple of days the FTP stops and I have to reboot the DVR to make it work again. While the FTP is down I can't log in to the video server or http either.

 

Message is "Could not send reply, disconnected". I have tried a couple different FTP severs (BabyFTP, FileZilla server) and get the same thing. Works for a couple of days then dies.

 

Anyone seen this before?
