im just using a simple panasonic wireless indoor network camera.
if it wasn't for HOA, i would still have the full blown security camera with night vision, but i was asked to remove them from the exterior of the house as neighbors (not my next door neighbors cause i talked to them) were complaining that it looked ugly.
i mean the thing is only 5" long and 3" in diameter it's barely even visible from the street.
so wat i started doing is installed flourescent twisty bulbs with photocell premounted in my porch and driveway exterior lamps and use that as my lighting. it actually works pretty well with the network camera. the image is on the grainy side but i can still see who it is and wat's happening in the middle of the night if needed from my droid.
the camera is mounted inside the window.
during the day the image is no problem.
i have it setup so it sends me email with attachment of the pict when motion is detected.
i can see in real time too from my droid using a IP camera app i bought.
there's better ones out there with night vision if you check amazon. just search network camera.
