I really appreciate our delivery. We selected several products and will be back for more. We had an oik vandalising and stealing property. This equipment not only gave us immediate stress relief because we knew we were going to be able to prove who was doing it, but it is quite a relief to go from victim to secret squirrel and vindicated party. I would also recommend the products for discreet installation for peace of mind or protection of an elderly person with carers or others that support them in their home. Products are easy to use so long as you can go up a stepladder and use a drill. Items arrive in plain outer and inner packaging so no one will know what is arriving.
