PAL or NTSC - but it is digital so it doesn't matter as to which one since it is just a pulldown in the setup screen LOL.
But do not update it. If you buy from Andy he gets better firmware than on Dahua site and it usually ships with the latest.
A common theme around here is don't fix what ain't broke. If the unit is working and meets your needs, in many instances an update breaks what you had working and provides you with something you didn't need. A Z12E that someone updated and then constantly reboots comes to mind, and a certain PTZ that loses autotracking with an update come to mind, a Hikvision ANPR camera losing half the FPS and ability to read US plates - those are big deals to have happen. Don't do it unless it is fixing a problem you are experiencing or adds a feature you really need.
Do not update for the sake of updating LOL.
Most of us here do not update the cameras, especially if they are working for what we are doing. Someone posted here just yesterday updating the 49225 PTZ (despite all the warnings everyone posts on here about that firmware update) and lost autotrack as that feature was removed in subsequent updates...
