We've had software issue's, minor issue's ,fixable in the field or single camera issues.
Not a lot . and not the the quanity's i read about other s having.
Some are related to software to vms issues.
We've had more HV problems , than arecont issues , even as i dont think arecont has the greatest software in thier cameras.
my own personal view
And we think it's related to upgrades from 1.3 to 3-5 mpxl issues or codac compatabliliy issues . as when we upgraded the vms, or cameras software it solves the problem.
some were overtaxing the switch
where spec's said 24 cam's at 45 watts per channel , when we ran at full speed with 24 ,3-5 mpxl with irs and motion with constant bit rate , it created problems .
set switch's to 20 cams with 4 open , treated it like it was electrical , not I.T.
Dumbed down some of the cameras and it solves issues.
With this in mind we concluded the switch would not work at the specified listed detail.
Cameras Drop off's , not sure it was the camera so much as the infrastructure or power, or Switch issue.
Spikes, surges, fluctuation in environment, Extremes heat, cold
As a really Good technician or troubleshooter , you look for answers and tech support gives cookie cutter book answers and as a problem solver i have to get to the end with a solution that works in the field .
some time s you have to be creative to find solutions .
sometimes it is easier , simpler to just change out , test in shop, troubleshoot in a good environment on a bench.
This takes a lot of time and thought ( you don't get Paid for )
