hint:
that cam is prolly IR based, most low light cams are.....
not infra red like you see in the movies, where everything is green and yellow... more like black and white, like you would see in military footage from the gulf wars....
to make it see in the dark, you need IR leds... invisible to the naked eye, they will cast a 'spotlight' only the camera (and you behind the monitor) can see.
some low light cams have them built in, looks like a bunch of dark led's around the lense. you can find them @ sams club and home depot pretty cheap.
another hint- though ip based cams are nice, whats even better is an ip based DVR.... an ip based dvr not only lets you view multiple cams using just one IP, it also records the images for later use... like handing them over to law enforcement, or to that thug you hire to rip the balls off of whoever cleaned you out.there are literally dozens of options to play with, one of my favorites is setting up a 'motion capture zone' for a camera, or series of cameras. its pretty simple, you point the cam @ whatever you want it too look @, then using the dvr controls, you can draw an outline, or box, of just about any shape, over the image the camera is capturing... then, from that point on, if anything moves inside the capture zone, the camera instantly starts recording..... some dvr's are so good at this they have whats called 'follow me' mode, using more than one camera, the first time movement is captured, the dvr uses logic to literally 'follow' the intruder through the series of installed cameras... kind of like the sequence of shots you see edited together for news clip, the dvr does the editing for you, as it happens... there's alot more you can do... covert cams, cams set up to alert you via cell/txt, etc etc....... even 'fake' cameras, or dummies, placed in a highly visible location, can be twice as effective of keeping out intruders as a backyard full of dogs.
