WECL in SSP looks like a major official distributor of Hikvision gear. They've got a load of IP cameras (including the fancy PTZ and weatherproofed domes) as well as the recording systems.
It's worth point out that not all cameras are IP cameras though (I think they're referred to as CCTV, I'm not sure about terminology)
The guy in the store said they come with English firmware.
Their website has their address on it, but otherwise the website sucks a bit. It's definitely one of those places you go to in person rather than online.
