The MC500-W offers both WiFi and USB live image output with up to 5.0 megapixel (2592x1944) resolution. A switch on the side (Off/WiFi/USB) places the unit into WiFi mode and after downloading the App, it is a simple question of connecting your mobile device to the Kopa network in your WiFi settings. Occasionally, we have found that making the actual connection can take a couple of tries (typically due to other networks on the same channel), but beyond that the network is refreshingly reliable.
