Minimising image noise within the recording of indoor office environments
The first thing is to make sure any gain is off.  Gain on a video camera is like high ISO on a digital still camera.  It increases the noise floor significantly and causes much more noise in even a good image.  This should make the camera make other adjustments to try to preserve the exposure with a lower noise floor.

If there is still too much noise, it may require that the dynamic range of the scene be reduced with properly placed lighting to eliminate dark shadows.  If you have particularly bright and particularly dark areas, the camera may attempt to get detail in the dark areas and result in noise.  Reducing this dynamic range will allow the detail to be captured clearly in all parts of the image.

It is also possible that there simply isn't enough light.  It can be very dark inside buildings.  Our eyes are exceptionally good at adjusting to a wide range of lighting intensities so we don't really notice it much, but outside is hundreds of time brighter than inside.  An average office hall lighting is about 80 lux.  A typical sunny day is over 10,000 lux with over 30,000 lux in directly sunlight.  That's a HUGE variation.  The camera you mentioned seems to have good low light performance for it's price range from the CNet review, but if you still have too much noise after adjusting the gain to 0 or have too dark of an image, then your primary option is to throw more light at it.  Good strong studio lighting should allow the sensor to clearly pick things up in such a way that the images will be suitable for computer vision with low noise.
