Is there a difference between community speedwatch devices and police equipment?

For speeding offences my local police force has stated that CSW (Community Speedwatch) operates the rule of 10% + 3mph. CSW equipment is different from SEU (Speed Enforcement Unit) equipment, which is why there is a slight difference. This is set the same across all but two police forces in the UK.

The 'difference' is CSW 'speeders' are treated differently from offenders caught by Speed Enforcement Users (the police), with a warning letter, whereas SEU infringers can be convicted.

The two treatments for speeding are anomalous.

Are you aware of this variance?

Although Community Speedwatch and the police both carry out speeding detection, what is then done with this data is different because of the rights and responsibilities afforded to them. Community Speedwatch programs are carried out by local volunteers, and they have no authority to enforce the law, hence a letter is sent to the registered keeper of the vehicle in the event that a speeding occurrence is detected. The police of course do have the authority to enforce the law, but this is also with a degree of discretion as the National Police Chief's Council recommends that constabularies give a leeway of 10% + 2mph, but it is up to each constabulary how this guidance is applied if at all.
