Cross Beam Sensor
The cross beam sensor adds another whole dimension to your triggering capability. This sensor was designed for triggering on flying insects or birds. For this application having a one dimensional trigger just won't get you that killer insect in flight picture. The cross beam sensor is available in two different versions - Laser and Infrared. Lasers are much more adept at capturing extremely small objects and are better for long distances. IR has the advantage of not having a visible beam. Pictured below is the laser sensor with the diffusers (included) installed on the receivers.

The Ultimate in Flexibility
The sensors pictured above are the Laser Activated Cross Beam Sensors XBS_01. These sensors offer great flexiblity for mounting and triggering. There is also an indicator light that will aid in sensor alignment. There are several different modes these sensors can be operated in:
| A & B - A and B | Both A and B must be interupted before the output is activated |
| A -> B - A followed by B | A must be crossed before B before the output is activated |
| B -> A - B followed by A | Same as above but B must happen before A |
| A | B - A or B | Either A or B will activate the appropriate output |
With this flexibility in triggering you can configure StopShot to catch very specific events. For example, you can trigger only when your target is moving is a specific direction. For the "A -> B" and "B -> A" modes, a configurable timeout may be used to reset the trigger if the second event does not occur. This option minimizes user-intervention and allows you to capture pictuers only when your specific conditions are met.
Because we could not possibly come up with a mounting configuration that would fit all of the different applications out there, all of our sensors are designed to be attached to PVC, or electrical conduit tubing for easy design of custom brackets. They are also available with tripod mounts (1/4" x 20Threads). Custom cables are also very easy to make for our system. We use all standard cables that can be purchased at your local Audio Video Store. Below are a couple of examples of how one of our customers has built custom fixtures for his application.

These two fixtures were built by Linden Gledhill. The one on the left is for insects and the one on the right was used to take the picture of the Cockatiel on our Home Page.
