  4. Northumbria Police use an "Interval Time" of 0.5 seconds, i.e. the time for the second photograph to be generated, once the equipment has been activated and caused the first photograph to be taken. This "time" may or may not already be set after it has been returned from Gatsometer following  Annual Calibration. We carry out check at the start of each deployment and these include checking the "Interval Time", if required it would be set to 0.5 seconds.

  5. No information held.  There is no procedure  to show how the validation staff are trained.  They receive in house training annually by Camera Enforcement Technicians.  No assessments are undertaken and no certificates are given.
