The Detector is Up and Working!

Optex Infrared Detector

Optex Infrared Detector

For the past 30 years or so, we’ve had a complicated system of lines and sensors running down our driveway to alert us if someone was coming up the driveway. The system worked well for years, thanks to careful maintenance and troubleshooting by my husband. For quite awhile now, though, it’s been wonky and unreliable.

We got a new sensor and laboriously installed it and connected it to the rest of the system, sitting beside our driveway in the hot. That didn’t solve the problem, and my husband started talking about trying to put a new electrical line in. This would mean hiring a trench digging guy with equipment to dig a trench 650 feet or more down the side of the driveway, put in the new line with some kind of protection, fill the trench up again, attach all the sensors, etc. and HOPE the problem was solved THEN.

I suggested that we try to look at the problem in a different way. I thought that MAYBE if we put some kind of motion sensor or the like on the garage end of the house, anyone pulling up to the house would set it off. THEN, if we could attach that to a noise thingie in the house, it would let us know we had a visitor.

A few days ago an Optex Infrared Sensor was delivered. We spent the evening installing it, leaving the wiring for another time. The next day my husband ran the wiring we needed. We got the noisemaker to work, finally, but there was a loud hum on the line ALL THE TIME. My husband has spent all day for two days trying to build a hum suppressor and get the whole system to work.

He just came into the office, sighing as he plopped down in his chair with an orange. I expected him to gripe about equipment, the vagaries of the universe, or such, and he said quietly, “I think it works.”

I jumped up and went outside just past the driveway pad and “VOILA!” the detector saw me and made the noise which sounded on all the speakers in the house and in the driveway!!!!!  AND there is NO hum on the line!

Rather than declare a victory lap and do something fun for awhile, as I’m typing he’s making a list of other things that need work so that we can prioritize them….
