Hi Stu
Sorry to hear about your problem.
I've recently got the 720p version of this
https://www.amazon.co.uk/YI-Wireless-Security-Surveillance-Available/dp/B074389PMT/ref=mp_s_a_1_5?ie=UTF8&qid=1528142278&sr=8-5&pi=AC_SX236_SY340_FMwebp_QL65&keywords=yi+home+camera&dpPl=1&dpID=31gMsvUGviL&ref=plSrch
The beauty of these is
1. Free cloud storage for motion activated clips for one week before being overwritten.....albeit only 6 second clips, FREE IS FREE
2. The app is really good.
Let's you crop a small section of the screen that activates recording so you don't get false alerts as trees in the background move in the breeze.
I've got mine targeting only 5-10% of the screen where my zed is, as people have to walk past it to get to my front door.
This means it only records when I have people coming to my car or house and not when cars drive past etc.
Alerts are sent to your phone and time stamped.
Click and view footage on the phone.
3. The cams take a memory card, this only records when motion is activated.
The phone alerts will give you the option to watch the entire motion activated event from the SD card or just the 6 second cloud clip.
