Dahua, they dont play Regional bullshit and I got full support in OSX, unlike Hik.. I am happy to buy from local suppliers that provide warranty and support, but the thing is there are a ton of cameras they do not sell here.. Ive got 2 PTZ's (well one is on the way) that were never offered by any US Retailer, and likely never will be.. my other PTZ and Fixed cameras were all bought from WrightWood, but they dont sell a vast majority of the models avilable on Dahua's International site.
The only thing people will complain about with Dahua is Firmware availability, all my cams run the firmware they were supplied with.. none need updated because all the features work as expected out of the box.. yeah they dont have as many features as Hik cameras, but unlike Hik all the features it does have work perfectly fine. (Network Storage im looking at you)
Hik created the Grey Market, they are responsible for its existance.. nobody else gives you so much grief for importing cameras.
Before IPCameras came around we were forced to local cameras because most all the imports were PAL formatted, with the introduction of IPCameras the regional crap was behind us.. but for some reason HikVision wants to hold on to the old ways for dear life... Any company that cares more about keeping its distributers failing business models propped up at the expense of there customers deserves this kinda criticism.
Sadly people will keep buying Hik, there hardware is great and affordable.. its just the software sucks!
