Solaire attends most of the San Diego trade shows. Our favorite would be the ones hosted by Westward Expos (at the Del Mar Fairgrounds in March and September) and the ACS Spring and Fall Home Shows (at the San Diego Convention Center). Lot of homeowners, lot of vendors.
ISC West for security integrators and CCTV suppliers. http://www.iscwest.com/
It is probably one of the best Tradeshows out there for the electronic security industry.
For our company it’s the World of Concrete in Las Vegas. Its more geared towards the commercial market, but its informative, and gives the guys some of the most fun workdays of the year
