The Complete Surveillance System
An example system
by Bob Mesnik
In previous articles we described the different parts of a surveillance system. In this article we put it all together. We create a real life requirement and then assemble a complete system. Everything is included from the cameras and lenses to the mounting brackets and power supplies. I also provided the reasons for selecting one product over another. So letís make our system:
How Does that PA System Work?
Or, those good vibrations
by May Kit Simpul
You never know where you're going to see a portable PA system. That is, if you can find it! Last summer, I was a spectator at a motorcycle racing event. Up and out earlier than a person should be, I found myself in the refreshment pavilion, staring at a breakfast menu on the wall. Too groggy to make a choice quite yet, I glanced around and saw the race director a few tables away He took a break from his pancakes and spoke a few words. He was right there in my sight, yet his words, "All racers must report to the track by 8:45" echoed back into the pavilion from far down on the track. I don't know about the racers, but that got my attention. He was here, but his voice was there! No wires, no cables! Wow! I thought - cool.
Some helpful advice
If you can't be kind, at least have the decency to be vague.
Don't assume malice for what stupidity can explain.
A penny saved is a government oversight.
The real art of conversation is not only to say the right thing at the right time, but also to leave unsaid the wrong thing at the tempting moment.
