Coffee pots are allowed in the dorms at the university I attend, but I am worried about the steam or smoke, whatever it is will set off the smoke detector. Other people use theres in my hall and the smoke detectors don't go off.
Look at the hub there will be a turn slot /knob if hubs lock manually
Most IR night vision cameras operate in a very high part of the spectrum 800nm or higher.. Nothing trick about it as just about every CCD, and CMOS chip out their is sensitive to IRjust most use IR blocking filters.. So you can buy real cheap, CCTV systems, ($99) 2 or 3 cameras and a control unit for it,,,,,,A VHS recorder, or even a digital storage device, with 8 or 10 gig capacity and 1 frame ever second can record days worth without having to eventually overwrite itself. Since IR lights also are pretty much invisible to the naked eye, you can get a dozen of them in an ARRAY and illuminate a large area without anyone even knowing you have lights on Here's a little example for you to explain how IR is invisible to the eye, but cameras can see it.. Take a digital camera, turn it on, and point a TV remote into it,,,push the channel or volume control, can you see the blinking IR light on the remote. Your eye cant but the camera can. Here's another cool test,,,,,,,,,,more complicated, but a poor mans night vision illuminator. Take some Wratten 87 filter, stack a couple layers, so you can't see through it. You should just be able to see the sun through it. Tape it over a MAG LITE, so no visible light is shown. Turn on your digital camera in Manual mode or video mode set exposure for longest setting, either 4 seconds in camera mode, or EV +4 on vid mode. Go in a dark room, turn on maglite, and shine on wall. Notice how the camera can see the shine of the light but it is still dark in the room..
no cheap way but it can be done , night vision and high Resolution is the only way to go. cheap systems will not give a good shot to id them
