Even so, wouldn't it be better to use 4 cheap cameras instead of 4 expensive smartphones?


4 cheap cameras wont have lte radios

seriously, pick up x4 $30 prepaid phones from walmart and they'll do the job perfectly


Probably not. Likely these were second-hand phones, so not terribly expensive. Also because they are phones, they can upload "to the cloud" automatically, have GPS and cell tower triangulation for accurate location reporting.
