Was looking for a WiFi based IP Camera and I've got these Sricam's already and they are pretty decent for the money. This is a bargain at £17.20 and even comes with a UK plug. I ended up paying £14.00 with my Gearbest points, so it made it even sweeter.
Has SD card slot, WiFi capability and is ONVIF compatible, so can connect to a ONVIF compatible CCTV DVR wirelessly or via ethernet port.
You can also pan and tilt the camera via a mobile device, PC or your DVR!
You can choose the priority line delivery option at checkout for no extra cost. From my experience, these are dispatched from a Europe address too, so no custom fees :)
