Catherine Zeta Jones could handle it! (Entrapment)It must be a good thief to handle this. I think no chance to get through it.
I use multiple trip lines, to get multiple push messages to my phone. This tells me it's unlikely to be a false alert.
Your zig-zag line probably results in a longer event. As someone drives or walks down your driveway, the tripwire "start" and "end" time are further apart in time. I've had problems with email alerts. The first email (start event) and third email (event stop) always get to my inbox. The second email, with snapshot, reaches me 50% of the time.
A longer event duration may help w/ letting the NVR squirt out the 2nd email, with snapshot.
Let me know if you have any thoughts/experience/tips.
