Are we licenced to sell security equipment?

Yes we certainly are.

We  hold  a  Master Security  Licence No: 409047541
Also a Class 2 Licence  2BC  Licence No: 409085880

To obtain these we had to undergo a full Police security check, and they also keep our fingerprints on file.  
Not only are we fully licenced, but all of our wireless security equipment has undergone extensive telecommunications testing under laboratory conditions in Australia and has full ACMA approval (Australian Communications and Media Authority) and meets all the necessary Australian Standards  applicable to wireless security equipment.  We are also members of ASIAL.

We have been issued with an ACMA supplier code number, which allows us to legally label our equipment with the A-Tick symbol and sell our wireless equipment throughout Australia.

N14075

The A-tick and ACMA supplier code number indicates compliance with the Australian telecommunications requirements and that the  EZY Security  wireless equipment can be legally connected to the Australian Telecommunications Network.

If you are looking at any other wireless security equipment ask the company in question if their products have the  A-Tick symbol labeled on the back of them accompanied with their supplier code number. If they do not refuse to buy, as it is illegal to connect any  type of telecommunications equipment to the Australian Telco Network without this label.
