Setup of the camera is easy for someone who is familiar with computing like myself, for normal users I recommend they read through the manual within the CD. To access the camera via WAN could be tricky for some people.
I want to verify here a question I had asked before I placed the order (I got 2 different answers from 2 different sale rep), the camera can run on its own wirelessly without the LAN cable attached (of course the power source is not wireless) after you have done with the cofig via LAN with the cable attached.
You can access the cam wirelessly via WAN from your smart phone or other PCs with WiFIi or internet without the PC at home turn on. I may consider to order a second unit for my back yard.
However, since the unit does not has built-in recording or SD slot, if you want recording your PC at home must be turned on in order for the cam to record to the PC's hard disc. The other option is to do the recording on your smart phone.
Image quality of this cam either day or night vision is acceptable good, considering the low cost of this unit.
