I would like to see a system that has the following criteria:

1) Needs to be durable and weather proof to meet a variety of applications both inside and out.

2) Should not as simple as possible and built off software and other systems that people already know if possible. Systems only the maker knows are not great in the field and trying to support a system that goes all over the world is not easy with time differences.

3) It should be compact and easy to install on a variety of types of lifts so it can be universally applied to all types of mixed fleets of different fuel types, truck types, etc.

4) It should be easily adjustable in range for different applications and preferences and to create as few false alarms as possible - too many and the system gets disregarded.

5) It should be able to tell a person from an object, to me property damage is second to people damage. Property damage is fixed with money but people damage is not. Forklifts work close to fixed objects all the time, very close. They should not be that close to people, they may be close but not that close. Something that senes a person (like the heat signature on infrared systems) might work well but would be costly. It could tell getting close to a person versus a wall or other item.

I have not seen a system yet mounted on a lift and sold in the US that I think is a good value. That does not mean there is not a good one, it is just not something I have seen or I felt it was overpriced and undersupported. Hope this helps.
