Looking for a wearable 'hidden'
video camera for PI use?

The choices are confusing:
Wired, or wireless?
B&W, or color?
RCA, or BNC?
0 lux, or 1 lux?
Fish-eye? Telephoto?
Which DVR is best?
Can it work with my camera?
Button? Pager? Covert?
Which type of power supply?
Lithium, rechargable, or AAA?
. . . and more!

John has studied these choices for years,
with extensive hands-on experience using them.
He knows the best and most direct choices.
You can guess, or you can listen to salespeople,
or you can pay John for a valuable consultation.
