QVIS Quattro-V2 firmware update help

Recommended Posts

Hi all,

I've taken over a DVR for a friend of mine, they are having issues with it crashing daily trying to do an "Upgrade please do not turn off"

Basically, the DVR locks up during this and doesn't respond to any input, the only fix is to turn the power off and on, the DVR then returns to normal operation.

I've had a look on the QVIS website for the Quattro DVR, they have a fair few DVR firmware available for the range.

I can't make much sense out of it, I don't want to apply one of these randomly and have it brick the DVR completely.

Some more details about this particular DVR.

QVIS 8CH Analogue (label on the bottom says Quattro-v2)
SYSTEM - V4.02.R11.B6996140.12201.141500.00100
Build Date 23-12-2016 10:27:04
Serial No 047455eadefbbd55
Status 17391


Does anyone know what Firmware this DVR needs? or how to find out?

Hi. Unit rebooting everyday will have nothing to do with firmware. 

This is a sign of a hard drive failure or a faulty camera. 

Do you know what format cameras you are using as this unit can be analog only or HD cvi tvi ahd

Hi Tom,


The DVR doesn't reboot, after a random period of time the display will show "Upgrade in progress please do not turn off the device"

The only solution is to force the DVR off manually as it remains in this "Upgrade in progress" window forever/

Cameras are all BNC connected, not sure if that tells you what you need to know, if not, I can check the DVR tomorrow.
