Hi all, I have purchased one NVR DS-7604NI-K1-4P and thre cameras, two of them DS-2CD2143G0-1 and one DS-2CD4A26FWD-IZS/P. Everything works ok, but wen using Hik-Conncet on IOS the Bullet camera apears offline. I tried to remove the device switch port but nothing. Playback works fine. Also using Hik-Connect on Android works fine. tried with two different IOS phone. Same result what should i do thanks.
