Fantastic unit at a great price. We bought this to replace our Oricom 710 due to issues with the night vision at distances beyond a couple of metres. Compared with the Oricom, the Nannio is cheaper, has a larger screen, better image quality, has pan and tilt, and a much better night vision range. I think the difference with night vision is the intensity of the IR lighting; you can see the red lights but they are not so bright to affect our toddler's sleep.
Image quality is great for an RF baby cam. I think some people don't realise that while this uses the same frequency as WiFi (2.4Ghz), it is not the same as a WiFi camera. RF and WiFi are both wireless, but RF baby cameras don't connect to the internet or your smart phone, which for some people (like myself) is preferred to reduce the risk of unauthorised access. The trade-off though is that image quality is not as good on RF compared to WiFi.
