What is a better home security alarm systems? Hardwired security alarm or wireless security alarm?

I am also looking for an alarm system for my business

  1. Hardwired security alarms will always be superior to wireless security alarms. The simple fact being, modern airwaves are being increasingly cluttered with Radio Frequency (RF) Interference. This which interfere with wireless security alarm systems are many and can range from the simple high voltage power line to wireless routers and radio towers.. The thing is, wireless is highly unpredictable, particularly in security alarm systems. You may have a perfectly sound wireless security alarm system for years, then all of a sudden the neighbour 3 blocks away decides to purchase a ham radio. All of a sudden, the monitoring station is getting panic alarm, the police are being send on what appears to be a weekly basis and you have fines from the city for excessive false alarms. Hardwired security alarm systems, on the other hand, are far more reliable in that they are not as susceptible to the problems of RF. Sure, if there is a strong source of RF behind a motion detector some of the older models may falsely activate. However this is simply fixed by replacing the detector with one with a higher level of RF Shielding. Fact of the matter is, no security alarm system is entirely free from the possibility of false alarms. Hardwired security alarm systems are, however, much less prone to issues. Hardwired security alarm detectors are also universally compatible between hardwired security alarm systems; Wireless security alarm detectors typically only function with the wireless security alarm system for which they were designed - this can result in expensive system replacements if one wireless security alarm detector fails. There is more information on the differences between wireless and hardwired security alarm systems on my website at http://www.keepsafesystems.ca There is an article entitled "the truth about wireless security systems" in the archive. I hope this answered your question.
  2. Hardwired alarm systems have less components and are inherently more reliable than wireless systems. While wireless security systems are much better than they were ten or fifteen years ago, I still strongly prefer a wired system. In the short run, a wireless system will be easier and quicker to install, and may even cost you a little less than a wired system. However, over time you will have more trouble with the wireless system and may need to replace batteries and certain other components. Think of the difference between your cell phone and a regular hardwired phone. When using a cell phone, the audio quality is generally poorer, there are delays in the signal, and you will occasionally drop a call. On the other hand, a regular wired phone offers superior audio quality, there is no delay, and you rarely get disconnected. The same basic comparison can be applied to wired-vs-wireless security systems. Wireless can make sense if you are renting and only plan on staying in the house a very short time, or if you happen to have an older, historic house where the running of cable is nearly impossible. Otherwise, you are probably better off with a wired system. In general, it makes even less sense to install wireless in a commercial or business application for the same reasons I mentioned above.
