A:Answer It's half off because its the older model, the new indoor camera is called Lynx Indoor 2, their outdoors are now called Lynx pro. Check them out on the web since Bestbuy doesn't carry the new gen of a very feature packed product. Ive had this very cam for going on 2 years i think and have had zero issues. Also didn't have to pay a single monthly fee, nor replace a battery every other day or be scared of a video loss due to lack of one of the features mentioned right there, is why the big names are sub par to this system.
