Upgrading/Replacing Cameras in Laundramat

Ah maybe so. I thought all the dahua cameras were pal. The turrets were also selected as pal, the only option given on empire and they don't have an extra p. Maybe only put when there's an option if that's the case

FYI - just a firmware difference between PAL and NTSC versions

in general does not make much too much of a difference
 
It appears the 4MP has the extra p as well and I overlooked it before so I guess you're right about it being for pal and I won't worry about it.

Now to figure out the best and most cost efficient way to power them all. A single poe switch with multiple cables following the same paths or single cables to clusters and branching with a poe switch.
 
Where do you find the latest updates? I should do that before mounting I think.

Updating the firmware before mounting would be a good idea. Not certain of the best place to get firmware.. did you get this from Andy? If so check which version he has, his team may already have updated it.
 
Yes, was from Andy. I had the boss order it so I don't have access to the ali account that ordered it, I'll try on here
