i have had mine for about a month, do have some problems as all has said interference, but to night we has some very small t storm, it recorded 6 out of 15 that i counted. mine is really only 10 foot from my display thru one wall that is mostly glass. what would happen flash occurred, it was raining, and it would not record it and say interference then kick back in to the listening state and lighting flash and i had interference notice again, it would do this at almost every flash , after the first one was detected. already relocated 2 times that why its so close now any suggestion on correction of unit are what causing this error .... i have now brought it inside the house it is setting on the table 2 foot away of monitor, storm has passed but display said still listening then in a few seconds it said interference again. then click back to listening state again.
