This is how! The first thing to do is decide what video you need and make sure you have the right equipment (see this guide for more details). Here are a few good options: A digital camera/camcorder/dslr / dht-spi device (see what the right brand is here) Light on Digital Video Light off Digital Video A light bulb (if you plan on putting a light in your bedroom for example) A dimmer switch for the nightstand Light Bulb A wall-mounted bulb Stand (make sure it is large enough to cover up more than one bedroom!) (it doesn’t matter if it has to be close or farther away depending on how tight you want to be)
How do I turn on or off the camera when I’m away? How to power it
How do I turn it off? How to shut it off Light on Light off
How can I get an idea if it has enough heat to be useful?
If I was using it at home, I’d have to give a lot of importance to this!
How do I turn this in for video?
For the nightstand to be used to run or hold a light for video, a digital video camera needs power. There may be a good deal of debate on what power specs you need, but the typical one should be 1a or higher.
Note that for the nightstand and video light above there are very useful adapters that you can buy, but not a lot of people will need them (and if you can get them you can still run the lights).
How does it work?
How does it work? This video will show you how it works, not how it looks in the daytime: It works by using a voltage sensor (known as a photodiode). A photodiode is just a sensitive device that can detect a small amount of light, much like a camera flash. That little bit of heat that is generated on the sensor is enough voltage to switch on the light or to open the door.
The trick is that the photodiode is not a light. And yet it works!
Light on (red), Light off (green), Closed, Powered on – this is a normal photodiode on a light switch.
