| Because configuring Scanguard is setting up a safety control, and it’s quite possible to put people’s eyesight at risk if things are not configured correctly. You should therefore have a good understanding of exposure levels and understand the significance of properties such as angular velocity, peak irradiance. If you are at all unsure that an exposure level is safe, don’t aim the laser effect at people. Learn how to set up the FB4 safeguard features on our Audience Scanning for Laser Show Designer’s Workshop. | Because configuring Scanguard is setting up a safety control, and it’s quite possible to put people’s eyesight at risk if things are not configured correctly.

| Specifies horizontal extent of the protected area within the scan field. The default position is 50%, which means that area below the vertical midpoint of the maximum scanning extent is protected by the scan-fail safeguard, and anything above the imaginary horizontal line can be projected without needed to be concerned about the beam velocity. The Horizon Level is usually set using a test frame and adjusted to operate a little distance above the audience to achieve a minimum 3m separation distance, as would be the case for any overhead laser effects. This allows effects, static beams, and finger beam fans etc., that could otherwise be hazardous, if projected into the audience, to be ignored by the scan-fail safeguard, and permitted to output into the area defined above the audience. | Specifies horizontal extent of the protected area within the scan field.

| The Horizon Angle allows a Horizon Level to be rotated by up to 45 degrees in either direction, which could be useful if the laser projector is not level, being mounted on an angled truss for example. | The Horizon Angle allows a Horizon Level to be rotated by up to 45 degrees in either direction, which could be useful if the laser projector is not level, being mounted on an angled truss for example. | ||
