Having been through the Choice survey of security cameras a number of times, I was still fairly disillusioned, and couldn’t see any product that I considered was worth purchasing on my limited budget. The best images quality was “80%” although exactly what that means as far as resolution goes is a mystery to me.
With most security camera footage, along with dash cam and my own rear-facing Fly6 bike camera, image quality is a big failure for all of them. I think it is a compound problem- lens quality is only mediocre, then video compression is applied, often leaving a rather blurry result. Far from satisfactory IMO, when reading a number plate is often impossible.
I have my old phone sitting around, and it has a perfectly good camera (although the USB charging connection is getting a bit dodgy), and delivers image quality better than any reasonably priced security type camera, so I figured it should be able to be used. I had installed a bit more capable camera app than the original Android/Google offering, which had motion detection, but getting those images to somewhere I could view them was an issue.
So I searched online to see what I could find, and sure enough there are apps that allow phones to be used as security cameras!
Yesterday I installed Alfred Camera, which at 4.8* was the highest rated. It was free, but I paid to remove ads and also to obtain clearer HD images. Videos are stored for 30 days, up to 2 minutes in length.
It has various adjustments for motion detection sensitivity, checking battery level, on/off scheduling and the ability to share with others via their GMail accounts.
I’ve only had it running a day or so, but am quite happy with it so far.
