Following a person

One of the concepts generated from this idea was that the light source would actually follow the persons instead of illuminating them. I believe that both would work however there are advantages to illuminating the target in a security sense.

New Look

This is a mock up of what the product could look like if it was trying to move a volume (light) as opposed to a surface (mirror)

Spotlight

This is my second attempt, this time I have attached a shape to track me.

This is an example of how the product could work in an industrial setting, tracking the intruder until they leave the environment.

Video tracking, working!

This is my first attempt at tracking using video.

I did this using Adobe After Effects and created a tracking path which I was then able to attach an object to.

I am pleased with the result and will try to create examples of concepts.

PIR sensors

PIR sensors come in different shapes and sizes, allowing for different detection distances. Typically an outdoor PIR sensor is working at a distance of 12 - 15 meters.
The model I am making will only use a short range 5 meter PIR because it will be used indoors as a example.

Watts

Looking at standard security lights available to purchase in store and online the average bulb for a floodlight model is around 200 - 500 watts.
The watts required for a spotlight model to allow it to be bright enough to illuminate a target area are 60 - 200 watts.
