I'm looking for something that will provide dependable motion for triggering a DVR. It's for a 8 foot wide driveway beside a house. I forgot what I used to use, but I do remember having problems with them breaking down, whatever they were. Thanks in advance David
You might want to look at The OD850 Series TriTech ® detectors are for use outdoors and in other harsh environments.

?Country=us&CountryLanguage=en&ShowCat=ST_NA%2eProductCatalog%2elobT2399697547 Rokonet makes an outdoor detector too. One even has the camera built in. WatchOUT provides selective event recognition utilizing Sway Recognition Technology that uses 2 MW channels to recognize and exclude objects that sway, such as bushes and tree limbs.
Those are good. I've used a number of the TriTech units back when they were still called Detection Systems (DS). They retail for about $120. For a high end, outdoor motion that's reasonable. I sell them online. Wholesale should be at least 25% less.

I had some bad experiences with early Rokonet products. This was over 20 years ago. Perhaps they've improved since then, no?
I never use Rokonet. I pull them out when I see one (because I am there to fix a problem they've created). They false, have poor catch performance, and poor reliability. Other than that they're great. I am sure some folks here love them and will say I am committing blasphemy against Rokonet. If I can't say much good about the line, I can say that the factory rep is a nice guy.
The Rokonet 6000's looked like good units... They had a look-down zone and everything. A "snap" to install and walktest, but the strange thing about them was the fact that after about five minutes of no activity in the room, they'd "fall asleep". You could walk from one side of the room to the other and they wouldn't "blink". When you walked back, all of a sudden they'd "perk up". We replaced a bunch with Paradox units... Never bought Rokonet again.
as well. Something to seriously consider, I wasn't
They (Paradox) make a model DG85 which I sell online. I've sold a few hundred of them with very few problems. They will false, however, if you aim them at moving foliage. Here's a link (my website) for additional info on them:

If your problem is with vehicular traffic rather than people, consider using a driveway monitor. Cartell, Mier Products, Sure Action and Winland all make magnetometer-based detectors that can easily be integrated with your video recording system.
Optex makes a decent PIR-based, wireless outdoor motion detector called a Wireless 1000 that we've for the purpose.
