Does anybody know about cctvs or surveillance cameras? I need a setup for my house. I tried looking on google and asking around but really didnt get any good answers. I need a camera that I can put in my bedroom window and point down at my car. I Need the following: Wireless Camera (Will be inside window): -Night Vision -Decent Picture A way to record to a External Hard Drive (prefered), DVR, or my computer. I only need to to be able to record 24 hours and then it can overwrite. Resolution doesnt need to be super great just decent enough to make out what's going on. I know pretty much where to get the stuff just dont know exactly what I need or how big of a hard drive I need to record 24 hours at decent resolution (480P?). Anyway, I really appreciate any help.
