Cnm 264 Secure DVR **Backing Up Problems**

[obextreme 0]

Hi all,

 

i was wondering if anyone could help me with a problem i have with my CnM 264 DVR

 

for some reason it wont allow me to back up any images i have.

 

i have tried many usb hard drives as the instructions state but it keeps coming up with "no Usb Device"

 

has anyone else had this problem and does anyone have any ideas on how to fix it ?

 

your help would be greatly appreciated as my house was badly vandalised and the images are needed for the police

 

thanks in anticipation

Note that many times the USB port on a DVR only has enough power for a solid-state USB jump drive, versus a USB hard drive.

 

Typically some hard drives have a USB splitter-cable to supply additional current via a powered uSB hub, a separate power supply, or even plug it into a nearby PC (it just takes 5 volts).

 

First thing to try is a solid-state jump drive, and the second thing to try is to add power to an external hard drive, but in your case I would try not to experiment too much with power til you get your footage.
