Have a small remote whose purpose I cannot recall. Has the word "TripWire" and some logo artwork. Hoping someone in this audience might recognize it.
A pic might help...
ETA: I say a pic might help because as you may have already discovered for yourself, doing web searches on the terms "tripwire" and "remote control," and variations thereof, yields a
ton of totally irrelevant sites and as far as I saw, not even a single potentially useful hit to follow up on.
Based on the lack of susbtantive responses to your post, it would seem that no one has actually seen the device you have, but someone might be able to make an educated guess based on whatever control buttons, etc. it has.
Also, have you tried opening it up, either just the battery compartment or the whole device itself, to look for a manufacturer name or any sort of other identifying marks/info?
