I have a bunch of 12 series Mobotix cameras around my house from a former life, but I am now ready to yank that and replace them. Since I was shopping on a budget, I thought it might be fun to make a bit of a game out of it.
Let's just say you have the cabling done and you are only buying cameras and SD cards. No NVR, nothing else... just cameras.
You have to buy 6 cameras and also must have a minimum of 3 outdoor cameras too. Your budget is as close to $1000 as possible. Go!
