Direct answerPair outdoor projectors with a thermostatic cabinet and use IP65-rated housings. This combination keeps the internal temperature and optical path stable through heat, cold, dust and rain.
The Two Building Blocks of Stability
Thermostatic cabinet
Heats in cold weather and cools in heat, keeping the projector inside its working temperature range all year.
IP65 housing
Dust-tight and resistant to water jets, so rain, spray and dust do not reach the optics or electronics.
Protected installation
Waterproof connectors, drip loops and lightning protection on the power and control lines.
Environmental Conditions to Plan For
- High summer heat combined with direct solar load on the cabinet surface
- Sub-zero winter nights that can slow or lock movement and electronics
- Salt spray in coastal and riverside locations
- Dust and sand carried by wind at open sites
- Power fluctuations at remote installations, handled with surge and voltage protection
For permanent landmark and bridge installations, confirm the local climate record before finalising cabinet specification and service intervals.
