Exterior siren for arlo pro 2

[Secureeyes]

Recently puchased an arlo pro 2 system, and found that the base unit siren is not loud enough to be heard outside. (Live close to freeway) Was wondering if there is an exterior mounted siren that works with/compatible with, arlo pro 2 system aside from the doorbell system that we don't really want. We really want a LOUD siren that we can remotely engage. Thanks.

Nothing Arlo sells as far as I know.  Some people speak highly of Samsung Smarthings which I believe can control Z-Wave devices as well as Arlo devices.  Perhaps you could build a multivendor system to do this.  Arlo + SmartThings Hub + a Z-Wave siren.  Perhaps someone else knows of a simpler solution.
