no name maker, but like this one

I cannot get the 2.4GHz link working, works wired in , clipped together.
Anyone know what the secret is ?

The camera is outputting syncs only , rather than CVBS is the main problem,
anyone know if there is a secret way in ? I suspect as supposed to be
waterproof , then a matter of hacking in.
It would be much more useful with a clipped on close-up lens, for reading
script, surprisingly not supplied

Convinced myself hacking-in only.
I hacked in along the mould line and accessed the inside without further
damage. 22 way bridge between CCD plus 2x LED and rest of pcb, maybe
fudgeable for miniture 7x7x10 lens and ccd . Whole ,with current pcb, could
be easily cut down to 12x 7mm access port instead of 16mm original. Anyone
knows of a simple "elephant trunk" mechanical manipulator mechanism? very
stiff and unweildy spiral steel trunking umbilical as is.

uses wbcam type lens and CCD and Vimicro 44 pin
VC0703NLEB
cant get any closer than
http://www.vimicro.com/english/product/d_vc0703.htm#
also 8 pin u724
6M xtal
outputs CVBS with 3.3V supply

vimicro is 48 pin , 15 thou/mil spacing

From this odd named file
http://www.sh2a.com/Microsoft%20Word%20-%202A-cmos.pdf
and pins 1,2,3,4, 7 tied to Vss and p8 Vdd , then the 8 pinner marked
U274
16B-1
probably an EEPROM but why ? NTSC/PAL selection would surely be just taking
some pin high or low on the 48 pinner. Contrast and brightness carried i2c
to the front end? will check later today

That PDF is for a USB camera which would need VID and PID info from
somewhere, hence the EEPROM. Your one's VIMICRO VC0703 chip is
configurable for a lot more than just PAL/NTSC. I would expect the OSD
feature alone to need an EEPROM to store the text and the rest of the
config might as well be kept in the same chip.
