Buying CMOS board cameras

Can anyone recommend a good supplier for CMOS board cameras? I've found a
few good suppliers but I want to ensure that I've done an exhaustive search.

And does anyone know of a wearable AV hard disk recorder that will take a
digital video input? What I really want is the camera and MPEG-4 encoder
from a video mobile phone with a 40GB HDD.

My requirements for the camera are:
* Low power consumption (<50mA)
* Good sensitivity (min illumination <4 lux)
* Low weight (< 30g)
* Small size (< 40 x 40 x 40mm)
* Colour
* Auto gain control, auto white balance, auto iris, auto exposure, auto back
light compensation

And ideally the camera will also have:
* Changeable lens
* Audio

Suppliers I've already looked at include:
* Maplin
* Farnel
* Quasar Electronics
* Rapid
* RS Electronics

I really like the OV7910 CMOS colour image sensor.

Many thanks for your help,

Do you REALLY want to use a CMOS camera? I presume you're trying to keep
the costs down, because a CCD sensor has much better resolution and
sensitivity than a CMOS one, the downside is that they are more expensive.

Hi Mark,

Cost isn't much of an issue. What is an issue is power consumption. I'm
building a wearable camera so the weight of the battery is a real issue.
Using LiPoly batteries I can power a CMOS camera + transmitter for 16 hours
on <60grams of battery. A CCD camera requires more like 150grams of
