Solar Ring Sign - an idea!

Hey... I really want people to see that my property is protected by the new battery cams, alarm system etc. HOWEVER, the solar sign is a great idea, but to spend £40 on a solar light that could easier be picked up and stolen (because I live on a side road off a busy high street) is a risky amount of money to spend. After a chat with Charles on the chat service this evening, I was asking if Ring sold a mount or if the item could be securely attached to a building. Almost simulating an external siren for the properly with its illuminated sign. I've ordered it, so see what the sign is like on the reverse and will try and come up with a solution, but I would really like someone to take on this feedback as whoever thought of this device missed a trick as we don't all live in a nice neighbourhood with big gardens and low foot falling traffic. I really think you could sell more of these if you sold it as a external wall mounted siren rather than a stake in the ground at £40! Agree or disagree with me.... go!
