What size mirror should I use?

The half dome mirror is used to provide 180 degree vision and is typically used in corridors ending in a T intersection or mid-wall to provide broad vision. For most applications (except industrial), we recommend the 60cm versions as best fit but consider the 45cm version if the width of the corridor is less than 1m or there are practical limitations preventing the 60cm mirror from being used. The much larger 90cm version is ideal for warehouse, industrial and some retail applications. Attach to pallet racks for fork lift awareness. The larger the mirror, the greater the view.

Can I use this mirror outdoor?

This style of mirror is for indoor applications only. Being a 'domed' shape, the mirror curvature is much deeper than a normal convex mirror and is necessary for creating the wider field of view. This style of mirror should be viewed at close range to obtain the best results which excludes its use as a practical mirror for outdoor. The image size and definition will be too small considering the larger distances normally expected in these situations.
