Security system project

[GfromR]

Hello, I'm building a security system for a project I have at school. My plan
as of this moment is to have a security camera that will rotate via a servo
motor and some sensors that will trip an alarm. This will be controlled by a
basic stamp.

The tricky part is I want to be able to control the camera and view the video
from another location. I'm not really sure how to go about that part of it.
Any suggestions or ideas would be appreciated.

Also any suggestions on making this project a little more unique are also
welcome.

Please email me if you have any ideas. Thanks...

The video should be able to be transferred on coax, while most
camcorders have some sort of interface that can be used to control
them. Search on LANC or Control C to see what Sony/Canon do on some of
theirs.

75R coax cable will carry your video signal well over a hundred metres.

To control the camera mount and respond to the sensors, a serial
communication method between two basic stamps would work. Do a search on
RS232 for information about serial comms standards. At the controller end,
a left and right button can then operate the motor while a movement sensor
like a PIR can trigger an indicator by sending serial data the other way
from the camera end to the controller.

Alternatively, you might want to save some time in the programing and just
use separate control lines for left, right and alarm. It means using a
multicore cable but the software only has to monitor single bits instead of
encoding and decoding serial data.

Good luck with the project
