My name is Allen Spears, I am the Chief Engineer at Rugged CCTV. Thought I would respond to what has been said here. First, as to our cameras for car washes, we currently own 4 car washes where we test all of the cameras and/or any ruggedizing we do to make them hold up in that caustic environment (coatings for the glass fronts that help to resist etching via the chemicals, silicone, seals, etc.). We've been doing that for 18 years.
As to our other cameras and products: we have always made our own DVR's. As to cameras, we buy most of our housings on the open market and stuff them with whatever guts we need. Several of the housings are proprietary designs that we have made exclusively for us.
Most of the stuff that we actually manufacture here in Texas (as opposed to simply assembling), are products that we hold the Patents on.
Hope this clears up any misconceptions. Questions are welcome.
