That depends on what you consider reasonable. The link I provided has enough detail in the images that you can build a pan & tilt from scratch. You can buy 'servo testers' dirt cheap on Ebay, or use a couple 555 timers to create the PWM control signals. http://www.ebay.com/itm/320669324825 $2.55 each, free shipping. I bought this monitor: http://www.ebay.com/itm/180666114346 And this camera: http://www.ebay.com/itm/300592681299 I bought this to mount it in. I thought what better way to hide a camera, than to disguise it as a fake? ;-) http://www.ebay.com/itm/180775138157 -- You can't have a sense of humor, if you have no sense.

For that kind of cash, one would expect very good resolution and aiming capability. Odd, that. --Winston

That would be helpful but I'm looking for the whole DIY open source project, the way linuxcnc.org is for CNC for example.

Their cheapest PTZ is U$800 ! Must be a *tiny* market. :) --Winston<-- Thanks, though. I like newegg.

The Panasonic line of security cameras are reasonably priced. Even for the Pan and tilt ones. <http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100010040%2050001009&IsNodeId=1&name=Panasonic> Cheers

http://www.ebay.com/itm/150749349731 is a kit of the mecahnical parts to use a pair of small servos. It is under $15. -- You can't have a sense of humor, if you have no sense.

Yeahbut, Power Over Ethernet would give one all the necessary functionality without too much sweat, at least for cameras shielded from temperature extremes. --Winston

It occurs to me that you could do hobby-level stuff with comparators (such as LM339) for sync separation _and_ data.
