[Elphel-support] hard drive/Disk Recorder issues

[Tom Sparks]

I just noticed when I run the camera flat on a table, the camera dose not reboot :)
when I put the camera on my tripod in the vertical position, thats when the camera reboots when accessing the hard drive

PS: I have connected to my router also :)

Tom,

If the camera _is_rebooting that may mean that the power supply is insufficient. Internally in the 12V version we use 9-36V DC-DC converter, but as the camera has input diode bridge, the DC-DC converter gets less, than the full input voltage. So the margin is not that large, and when the hard drive starts spinning, it can cause the short voltage drop and the DC-DC fails to provide internal 3.3V. Your camera has additional boards (10359, 10338) that causes more power consumption than a regular 12V camera with HDD, and while we tested it working we did not verify the margin.
that is
 starting to make sense as it reboots when I am trying access the hard drive
What power source are you using?
the one yous supplied
Can you try it with higher voltage (it can go up to 36V) to verify the problem? 

I'll have to do some hunting round the house to see what I have got (crossing fingers)
Andrey
