For those that have encountered MRCT and the new poliscan in NSW are they hidden or do they have appropriate warning like the redflex setups.

If they do have warnings then I'm not to sure there is any point in me upgrading to Stinger VIP at this point, apart from reducing falses and some extra range.

Just out of curiousity what sort of range are people getting with VIP on Redflex and MRCT?
