I'm not an expert, but have tried to usemultiple analog cameras before..and gave up in frustration
I only have one that plugs intomy Avermedia Tuner and with the 170 degree FOV can watch weather,
Meteors...stuff like that
Let's try this. I'm assuming you don't already have the DVR system linked in the first post yet....
Download the Ispy freeware, follow the link to get the (mediaportal?) fownload fror Windows Media Center.
Go with WIRELESS IP cams. Amazon has the Foscam with PTZ,. The older version with PTZ is #64/cam
I can control the IR light on the Foscam, so it sits inside, looking out a window. If you can't turn the IR off
it blinds the camera at night. I then have a few IR illuminators mounted outside that are tripped by moving heat
All of your cameras will be visible on your computers. Personally ,I don't use the Media Center Plaugin as
I can access my cams using an Itouch, and Ispy also has an android plug in .
It's a KISS system...one I can set up to run with my limited skills.
EDIT: If you are concerned others can hack into your wireless signal, then use Power Over Ethernet (POE)
This has the Cam hardwired to your Router and gets the necessary power either from an injector or the
suitable router. Just be careful when buying cams that all take the same Voltage, usually 12V.
One other beauty of a POE system is that you can power your cams/router and recording computer with an APS
incase you really think a perp will cut your power before breaking in.
