I am so impressed with this camera. Setting up was extremely easy and the level of customisation is impressive. It works almost completely out of the box, through I can understand if people with little computer experience may find it difficult.
It comes preset on 192.168.1.126 local IP address, and if you're like me, your router is set on 192.168.0.1 you'll need to connect it to your computer first with the supplied network cable, set your network up manually to the same subnet (I used 192.168.1.1) then browse to the camera at 192.168.1.126:81 (or whatever it says on the box). Once you login, switch on DHCP in "Basic Network Settings". Disconnect it from your computer and connect it to your router then browse to the IP address your router assigns it, not forgetting the port 81. From there you can reserve an IP to the camera in your routers settings (check your router manual on how to do that).
You'll also need to assign port forwarding on your router to access it from outside your network (again, check your router manual). However it does come with DDNS (Dynamic DNS) so you may be able to skip the last step, I don't know, I didn't test this feature.
It works in any modern browser, I tested it in Chrome, Firefox and Safari on OS X. It also works flawlessly on the iPhone.
The alarm feature is excellent, though I found that the most complex part to setup. In the "Alarm Service Settings" you need to enable "Motion Detect Armed" and "Alarm Input Armed" then choose your method of delivery. I chose "Send Mail on Alarm". The scheduler UI is a little poor, having to set each individual 15 minute block for the week but I didn't bother with it and left it off, which sets the alarm 24/7.
To disable the alarm uncheck "Alarm Input Armed". It would be nice to have an easier way to arm/disarm the alarm, toggling it requires a 30 second restart each time. But if you forget to arm it when you leave the house you can always arm it when you remember from any computer.
Once you have set up the alarm, you'll need to set up your email (or chosen delivery settings). For email go to "Mail Service Settings" and enter the sender email (you can enter your own) and your receiver emails (also your own).
If you're using Gmail, then set SMTP Server: smtp.gmail.com, SMTP Port: 465, Transport Layer Security Protocol: TSL, Need Authentication: Yes, SMTP User: <your email>, SMTP Password: <your password>. Check the "Report Internet IP by Mail" checkbox if you want to be reminded on how to access the camera (particularly good if you have a dynamic IP address.
You'll now get a 6 nice images of yourself delivered to your inbox when ever you walk into it's field of view.
One last note, the night vision is excellent and the resolution is perfect for its intended purpose. For < £40 this is camera is a must for any security conscious folk.
