Outdoor Security Beam Motion solutions
It is prudent to avoid low bid when having outdoor motion detectors installed because time is money and having employees, guards and dispatchers wasting time on false alarms will end up costing you money. Use the better technology motion detectors even through they are more expensive. Have the proper direct burial installed from the get go so ou don't waste money having to replace wire in a couple of years because of water or sun damage. The DS453Q Bosch detectors have a range of 360' and you can use the PEH2 heaters (2 come in one kit) and you can use the PC1A weather enclosures to further protect the motions. Optex detector are also a great option but they cost even more money when looking at the higher end security motion detectors.
