A DVR Sentry Watches Your Site

Should something suspicious take place, the video cameras can be accessed remotely and in real time.

Robbie Green is the IT manager for Cumulus Houston. He points out that in Fig. 1, the security cameras almost look like spotlights. To the uninitiated, a daytime visit would be caught on camera.

Robbie and his crew went a step further. When choosing cameras, they bought models capable of night vision. Next was the purchase of a DVR that records inputs from both cameras. The DVR is capable of e-mailing a message whenever it detects motion. The e-mail will include a still image of the motion that triggered it.

Robbie and his staff also added a new security light out front. It’s motion-triggered, only at night.

Fig. 2 shows two DVR images of someone at the front door. No, it’s not a copper thief, it’s Cumulus Engineer John Whiteside. He’s installing one of the super-secure locks, seen in Fig. 3.

Robbie adds to bring your blowtorch if you forget the keys — no one is getting past those doors.

Great ideas to keep sites safe.

Wes Boyd, market engineer for Cumulus Youngstown, often passes along useful tips for Workbench readers.

He’s done it again with news of TinyCAD. This is an open-source schematic capture program for Windows, available for free from Source Forge.

In addition to being able to simply print your designs, you can use TinyCAD to publish your drawings by copying and pasting into a Word document, or saving as a PNG bitmap for the Web.

You can also use TinyCAD as a front end to a PCB layout program (see the links), by getting TinyCAD to create a netlist of your circuit.

TinyCAD is open-source so you can use it for free, and you can download the source code for use in your own projects. Here’s the link:

For help and support, go to the Yahoo! group called TinyCAD. In this group you can talk to other TinyCAD users. It’s an excellent place to start if you are new to the program.

Thanks, Wes, for a useful — and free — tip that will help everyone become more productive.
