[QUOTE="Doc Hudson, post: 417031, member: 1607"] The whole point of an alarm system is reliability and fail safe operation at the key moment when you need it to alert of a break-in. If a key component fails due to the battery getting a bit to low to operate successfully, or due to poor signal strength, or due to obstructions blocking signal, or other wireless interference etc. then you may as well just pop a dummy bell box and few dummy sensors around the building as a visual deterrent. Where hard wiring is a feasible option its reliability is generally superior to wireless. (such as the similarity to the data reliability and speed with internet connection). In my opinion for a reliable system a designer will reduce the potential failure areas to an absolute minimum, rather than increasing them. Wireless system can work and do work in many applications, but are more costly to maintain and run over the same period of time than as wired system. If you have access to all of the installation and user manuals I doubt you would find a wired system too difficult to configure, maintain, expand or fix should the need arise. With just one main battery to replace around every 5 years typically costing less than £15.00 it can be far more economical than changing a lot of sensor batteries as well. Doc H. [/QUOTE]
