One of the issues is around consumer grade versus commercial grade equipment. We might just buy a camera from Jaycar or the Internet, put it inside a window and point it out. CASA, to do it properly would need to find a suitable 24x7 all weather unit, one with 3G/4G capability, weather-proof it, mount it on a pole, determine best direction, arrange a contractor to mount pole, arrange a suitable location on the realestate, power the unit be it solar or otherwise, then maintain it by cleaning the glass, updating the firmware, etc etc. Then there's the contract for the 3G/4G connection. If you ran up a tender for say 80-100 of these, it would be a fairly significant spend for installation and maintenance.
Absolutely we would love to have these available but also need to understand the cost implications and that these things take time once initiated and I don't think we are even at that point yet.
