Greetings. I bought this Blue by ADT Camera at a garage sale second hand. I don't even remember where it was. I'm wanting to set it up, I hoped tiny cam monitor or something would work. I downloaded the ADT app to my phone, but it won't install without an email associated at time of purchase, which I have no way of knowing. Is there any way to make use of this camera for simple monitoring or is it just garbage? Thank you
