Hi Marcelle,
You might want to try our innovative new product; http://www.centrasecurity.co.uk/security-products/domekleener/2778/ 'Domekleener' for cleaning CCTV domes. It enables you to clean camera housings without the need for ladders, scaffold towers or ‘cherry pickers’ (max safe dome height 30 feet with a standard pole).
The Domekleener’s design ensures that as pressure is placed on its arms they will spread allowing the cleaning blades to easily pass over the dome without damaging it.
You can find out more about our CCTV cleaner here: http://www.centrasecurity.co.uk/security-products/domekleener/2778/
However, please do not hesitate to get in contact if you have any questions!
