Not sure, the box the cam was in had all what appeared Chinese writing on it see pics below.
1st a little background.
About 4 years ago I got the nvr and 4- 3mp bullet cams, just plugged them into the nvr and 10 seconds later everything self configured and worked right out of the box, easy...
I recently ordered through Newegg the DS-2CD2332-l turret style cam, and to my surprise when I opened the box I received a DS-2cd2335-i with the firmware being V5.4.0
It was never able to connect with my Hikvision DS-7608NI-SE/P nvr, so it went back.
I'm ordering DS-2cd2335-i from another...
