20. The assessment.
Check list
− Was a baseline done?
− Are the measurements in valid positions?
− Good quality calibrated light meter?
− Maintenance factor – MUST = 1
− Surface reflectance's allowed for?
− Vertical measurements – how high?
− Horizontal measurements – at what height?
− Hedgerows….
− A contour line drawing, really doesn’t tell you all you need to know

21. Post installation.
− Do you ever go back and check you got what you were promised?
− This is why your baseline is vital.
− Add it to planning conditions.
− If it doesn’t match what was advised – something MUST be done, not SHOULD.

− Can be Power Over Ethernet (POE) or battery
powered.
− Hard network, Wi-Fi or LoRa WAN.
