Replacement for RE104 driveway sensor?

Does anyone know if there is a replacement for the Resolution products RE104 driveway sensor or if someone else makes a wireless sensor that uses Crystal or Honeywell wireless protocols?

Just throwing this out there, I always sorta wanted something like this, but found that this is way easier to implement (obviously, situation dependent): https://github.com/blakeblackshear/frigate
I've got a camera on my driveway, and I just use this for object detection and it works 99.9% of the time. 

Interesting idea. I have a Geovision DVR and lots of cameras. I've never used object detection. One challenge I might have, I am in a rural area with lots of wildlife. Don't want trips from deer, bobcats, and the like.

I have a camera/light that I believe uses that software.  I can detect animals, humans, cars, and other, and you can detect which ones to activate. It generally works OK but does get a fair amount of false alarms. It zooms in on the trigger and takes a picture of that, which is nice. But again, false alarms.  I also have two RE104's and they have been there 6+ years.  They always work.  Occasional false when a big truck drives by, but sensitivity is probably a bit too high.  

i am also using frigate. using the zone builder, i have split my driveway into 2 zones, driveway0 near the street and driveway1 closer to the house. using the mqtt messages frigate generates, i set up notifications for when a car or person is approaching (was in zone driveway0 and now in zones driveway0 & driveway1). it works in the opposite direction too - i can track when people or cars leave.

I had the Resolution sensor at the old house.  When I moved to the new house a few years back, I went a different route.  I have a pair of the Dakota Alert Driveways sensors with the receiver hooked up to an Arduino that is integrated into Homeseer.  I can get direction of car motion using timing on the two sensors.  It gets it right about 95% of the time.  I have a default setting that catches the rest.
