According to EQdruid, a forum user, you can hook up your PS3 and PSP to have a home security.

"OK, I was messing around with the PSP to PS3 Remote use. Here's the set up.

One of my PS3's is downstairs in my living room. I turn on the PS3 to Remote play, and run upstairs to listen to some tunes and such while upstairs.

Now my PS3 has an EYETOY hooked up to it, so I was wondering if I could start a Video Chat with my PSP thur Remote play.

Sure enough It works.... Not only could I get another person into my Video chat, but I can also see my Downstairs living room on my PSP FULL SCREEN.

I played around with it, and now if I wanted to watch what ever was going on where ever my PS3 is I can thur remote play.

This means once Remote play can take place thur any WiFi area, you can leave your PS3 on, Just to see what is going on at home where ever your Eyetoy is facing."
