NATA logoCEOS is accredited to ISO/IEC17025:2005 by NATA to test enforcement cameras and delivers a range of services including camera sensor testing, camera reliability testing (camera versus TIRTL detections), camera accuracy testing (calibrated test vehicle) and time into red testing (calibrated timer).  Our scope includes:

Calibration of a vehicle with digital display of speed using CEOS Method PJ061, with least uncertainties of measurement of: 

1.1 km/h at speeds from 15 to 120 km/h

Field measurement of inductive loop devices using CEOS Method PJ047, with least uncertainties of measurement of: 

DC resistance: 0.17 Ω + 1% from 0.5 Ω to 100 Ω
Inductance:  16 µH from 40 µH to 240 µH
  17 µH from 240 µH to 350 µH at 1 kHz

Field measurement of piezo electric devices using CEOS Method PJ048, with least uncertainties of measurement of:

Capacitance:  0.08 nF + 0.8% of reading from 2.5 nF to 20 nF
  0.61 nF from 20 nF to 25 nF
  0.70 nF from 25 nF to 50 nF at 1 kHz

Field measurement of piezo electric device voltage to IEC 60359-2001: "Electrical and electronic measurement equipment - Expression of performance" with least uncertainties of measurement of:

8% from 20 mV to 200 mV
5% from 200 mV to 1 V
3% from 1 V to 100V

1.2km/h from 20 to 150 km/h

Field measurement of time that a traffic signal phase is activated using CEOS Method PJ051, with least uncertainties of measurement of:

0.6 s from 0.0 to 60.0 s
