I am looking to purchase a hand held speed camera for site to assist with regulating the site speed.

Has anyone any experiance of a relevent product

Any help would be appreciated

Kind regards

Angelo

I used them with variable speed signs back in the day...I have found that as the technology gets better cameras with photo options have helped to reduce the potential conflict for Security staff, HR and others who may have cause to use them...

We've encountered the same issue on our site with visiting hauliers and contractors, and are addressing it in a slightly different way.

We've installed a couple of the speed monitoring signs that you see outside schools, but have additional mounts at strategic places around the site where we can move the signs at a moments notice.  The signs record the speed of vehicles approaching from both sides, which can be extracted by bluetooth and compared to CCTV so we can feed back to the contractors which drivers are taking the proverbial 'mickey'.

Our next step over the next couple of months is to fit actual speed cameras that will take photographs and send them via a mobile sim card so we then have additional proof we can send straight out without having to extract the data and compare to CCTV.

"Speed guns" can be really appropriate or a complete waste of time.  Both hand held laser & frequency types (radar) need to be focused on the target vehicle for a minimum period - typically during which the vehicle will slow or the operator gets distracted, or you run out of distance to complete the check.  
Its then a matter of how to confront or educate the driver. Typically its being stopped at the time and shwon the resulting speed reading with accompanying time stamp shown to validate it.  Part of the cost is paying to have someone sdtanding there - already a signal to the road users that a speed check is in place and defeating the excercise.  
By all means borrow a 'speed gun' as a trial but don't buy until its tried.  
Assuming you have an issue, I'd suggest buying / hiring a static speed check device with accompanying camera system.  They are movable and drivers are never sure if they are on or not (active and passive enforcement).  The data can be downloaded directly or remotely.  
If you decide on an enforcement approach.  Make sure you ahve the policies and systems in place to support the actions being taken, whether it is to report offenders to the visitors, deal directly with the driver on site as well as the sanctions to be taken - advice, written warning, exclusion from site etc.  The key offenders are as liekly to be the site resident employees as it is visitors - be prepared for those results and aply the rules equally rigourously / gently to all drivers.

research into driver psychology has shown that there are only a few who are totally reckles and endanger others and a more complete road safety approach would be to educate and enforce as engineering won't change thier behaviour...driving is a skill based, rule governed, expressive activity...we all know how to operate the controls and we all know the rules..however it is our personality we apply to the other two...wither that is two wheels or 18...

understand, educate...enforce (if necessary)..then monitor....
