RLC-810A Non-Detection Zone still triggering!

Has anyone else experienced (or is experiencing) triggering in areas that are already covered as "Non-Detection Zones".

I have an RLC-810A and it is triggered, sometimes, by cars/vehicles (especially red ones) passing through an already set non detection zone. I've checked the setting to ensure there are no missing squares and have several times now deleted the area and started again. This is not a continuos trigger, but happening every so often. It's interesting that red cars or vehicles seem to do this worse and I was wondering if it's something to do with 'leaky' infra-red detection during the day? Detection does not identify these as 'cars' but rather as a normal 'any motion' event.
It seems worse if sensitivity is set too high which is annoying. Seems that something is 'leaky' on the setting that's allowing unwanted detection. This does not happen at night under infra-red operation but rather in colour mode during daylight hours.

I also experienced that. A car passes behind the "non detection zone", and even if 1% of the car is outside the zone, it gets recognized.
Enlarge the non-detection zone - that's what I did.
It can also recognize and detect people and cars through fences

Kind regards,
