So I was given a RC8025B-ADT from my aunt because she didn't use it and does not care for it...but she really gave it to us because we have a autistic son that has outburst once and awhile so I wanted to set this up in him room to keep a eye on him but have no clue how to set it to my router and what to download to figure it out..and ADT wants to charge me alot just for them to take charge of how can i get into this one???? Would really help out alot. Thank you.
