hello, I have 3 Hikvision Wi-Fi cameras model HWI-B120H-D/W and I want to view the images outside the house, but they do not work over Wi-Fi, only through a network cable, I have already configured the Wi-Fi on the camera, but it only works with the home network, how can I configure the wi-fi to view images outside the home on my cell phone? Could you help me? thanks
PS: Do I need a DVR-NVR?
