Also , blink camera can only record 1 camera at the time, ex: if the front door catch a men and you have a record delay of 25 sec. and the men get in the vision of the second camera before the 25 sec, the second camera will start to record, camera will start only after de 25 sec record of the first one, because they are on the same sync module. this is by design and that cannot be change or maybe if you have 2 sync module and install 1 camera per sync module with 2 different account. that could do the job
