Does anyone have a document that details what the camera settings should be in various light conditions? I realize that it varies given the time of day, weather conditions, etc. Just looking for a starting point.

Aditionally, the camera have a three position button on front (high, normal, low), and you must increase the qty on ring behide focus control.

Three position button on front?? Id love to see the camera you have.
BV Timing
Try the manual. It gives explanations as to gain, brightness and frequency settings as well as opening the iris for low light. The link to the article is great if you have a directional light to use for the finish line but other settings can help if you dont have one of them.

I think, this depends on the lens mount.
We do have one camera (etherlynx 2000, I belive c-mount) with this "button", which moves a filter in front of the sensor, and another (I think that's the f-mount camera), without it.
Hi all, I use an etherlynx 2000 with the 3 position switch on the front. If you remove the lens you can see the switch moving filters. Position 1 is no filter, 2 is one filter and 3 is two filters.
Could anyone explain the difference between Aperture & Iris. So far I have been keeping the aperture on the lens closed at much as I can and opening the aperture for low light conditions. I watch the AGC and when it gets close to 250 I open the aperture one or two stops. But I have been leaving the Iris setting in the software on auto. I did have problems at one race meeting where the track lighting was not good enough and could not capture the images after the sun went down.

Aperture is the size of the opening that lets the light in, iris is the device that controls the size of the opening, they are usually used as interchangeable terms. When the gain gets high you are more likely to get "noise" in the image. The noise can look like snow. Try keeping the gain less than 100. In very low light levels try switching to a manual capture and then do an enhancement before trying to read the race. The camera can pick up an image that will not set off the auto capture,the enhancement helps adjust the contrast to find where you want to put the time line. Remember that you must have some light to get an image, a car's head light will almost always be bright enough to see a body.
Iris settings are for F-Mount Lens.
For a c-mount, you can do several things in lower light:
1. manually increase the gain (also on agc set the max gain higher than the 150 default) as necessary.
2. open the aperture (manual or with the aperture button under hardware control if you have an automatic lens).
3. Some cameras have a switch on the front of the housing to the left of the lens as you look at it and it does low, normal and high filters. Slide to low.
The wider the aperture (lower number is wider) the less depth of image you will have in focus, so as a general rule, the closer to 16, the easier it is to focus and the more of the track that will be in focus (all should be in focus at 16, most at 11 and declining from there typically). So typically you do want to work at the highest possible aperture setting that allows good picture, in my personal experience.
Hope that sheds additional light ...
You can adjust autocapture in low light to be more sensitive, or go to manual capture when required.
The new vision line of cameras have an available lux boost feature for low light. All existing cameras are eligible for a credit against trade in and if anyone wants to know their trade value compared to price of a new camera, let me know. You can also get digital filters on the vision. Trade credits are open until August.

Thanks for the replies.
I have a race meeting coming up that goes into the night. I am not sure how lit the finish will be. The camera has a manual aperture so I will keep it on the highest number I can. I will try the manual capture if the auto capture does not work. I use an auto capture of about 20 in the day and reduce it as needed.
