Disclosure Details

Speeding - 1176/16

Dated: 01 Nov 2016

Provision of information held by Northumbria Police made under the Freedom of Information Act 2000 (the 'Act')

Thank you for your e mail dated 24 October 2016 in which you made a request for access to certain information which may be held by Northumbria Police.

As you may be aware the purpose of the Act is to allow a general right of access to information held at the time of a request, by a Public Authority (including the Police), subject to certain limitations and exemptions. 

You asked:

I would like to request a FOI disclosure for the calibration and maintenance specific to the manned equipment that was operating at B6918 Ponteland Road, Woolsington on 17/10/2016 at 9:06 and how the speed is calculated as part of the secondary check. 

Please can you provide evidence of and/or answers to the following 5 points: 

1.A current and valid calibration certificate specific to the camera detailed above 

2.After the camera has been returned following calibration please confirm if, apart from the calibration certificate, anyone provide a report on any faults detected and items replaced and, if so, please identify the items and what dates they were replaced, including batteries, that have required replacement.

3.After calibration, please confirm if the cameras are returned with a shutter speed of two photographs at intervals of 0.5 seconds, and if your Camera Enforcement Officers make any adjustments to the shutter speed or flash setting prior to reinstallation and, if so, what are the setting adjustments?.

4.Regarding the secondary check viewing, please advise how the viewing staff are trained for their task, who does the training, are certificates of completion provided, and are the staff given post training assessments or hard copy reference documentation.

5.Is the work of the viewing staff audited or reviewed at intervals?

6.Please confirm the distance between the calibration lines on the road which are part of the secondary check, so that one can calculate the speed if five lines are passed. As this is manned equipment, if lines in the road are not used as part of a secondary check, please advise what is used for the secondary check


We have now had the opportunity to fully consider your request and I provide a response for your attention.

1. See attached.

2. No information held.  Cameras are returned fully operational.

3. Not applicable to manned equipment.

4. As this is from a mobile van unit there is no specific secondary check viewing which we associate with fixed camera's and the distance travelled between the two shots.

With regards to detection from the mobile van unit, operators are fully trained by the manufacturers and this training is cascaded down to the Fixed Penalty Unit staff.

5. The system is dip sampled by the Unit Sergeant and Supervision within the Fixed Penalty Unit

6.The laser detects the speed on manned equipment activated by  the operator  who then corroborates the speed with their opinion.


Due to the different methods of recording information across 43 forces, a specific response from one constabulary should not be seen as an indication of what information could be supplied (within cost) by another.  Systems used for recording these figures are not generic, nor are the procedures used locally in capturing the data.  For this reason responses between forces may differ, and should not be used for comparative purposes.

The information we have supplied to you is likely to contain intellectual property rights of Northumbria Police.  Your use of the information must be strictly in accordance with the Copyright Designs and Patents Act 1988 (as amended) or such other applicable legislation.  In particular, you must not re-use this information for any commercial purpose.
