FAQ


1. What is the difference between a plasma light and HMI light?

Have a look at this comparison video from HIVE showing you the difference in colour quality between Plasma and HMI lighting types.

2. What is the difference between a consumer high speed camera and a  MACS high speed camera?

When  buying a high speed camera always consider the old adage, "you get what you pay for" and high speed filming is also governed by that adage.

Some manufacturers of consumer cameras now offer a slow motion filming capability in their products. However to achieve the speeds required for high speed image capture a lot of critical functionality and capability are sacrificed. 

The most common features that are lost are : 
- Image quality, where the image resolution is extremely limited and the image is often heavily compressed. 
- Limited recording time - due to the design of the camera, typically on a very limited number of high speed frames can be captured;
- Generally these cameras do not have any shutter speed control - a major problem when capturing high speed events as most high speed filming is shot between 250 to 1000 frames per second (fps) but with a shutter factor many times faster than the frame rate to eliminate blurring, a major problem with high speed filming.  Without fast shutter speeds useful analysis of the result is worthless, also image compression also degrades the analysis quality of high speed filming.
- Inaccurate timing and inability to trigger the camera from an external source, limiting the usefulness of the camera.
