VEVOR LED Open Sign, 20" x 7" Neon Open Sign for Business, Adjustable Brightness Green Neon Lights Signs with Remote Control and Power Adapter, for Restaurant, Bar, Salon, Shop, Hotel, Window, Wall
I purchased one sign and considering purchasing 4 more. They will be working in close proximity to each other. Are the remote controls all on the same frequency? Is it possible to have more one sign in close proximity, and each remote works independently?
