Ronwhite on Howdy

Hey there looks like a great forum ya'll got here... Well names Justin and im a father of 2 girls 1 boy we live in Orange County Ca. and this I guess all this cctv stuff is a bit of a hobby if ya will. It all started when my youngest daughter was born and my mom was recently retired and pretty much had a day care between my 2 daughters and my brothers 3 . Well one day some weirdos were lurking around one afternoon and literally tried to open and come through the front security door with only my 66 year old "granny" and her swarm of kids home. Well long story short they ended up going to prison on warrants ,granny now has more training and a CCW,dog which shes had but the dogs getting old now, and a pieced together 4 channel cctv with a speed dome PTZ out front. (which is fun as all heck to play with ) but I just need some help on some questions that I cant seem to find answers to anywhere so I thought I would just cut the BS and go straight to where the pros are at ,so here I am lol
