When the wirefree burglar alarm made its first entry into the world market, there was certainly a bit of scepticism
There were initial complaints of alarms activating needlessly and not stopping for several minutes at a time. There were also complaints that the signal receptions of the wirefree burglar alarms were not as strong as the hardwired versions and therefore some intrusions could go undetected.
However, recent improvements in battery technology and further miniaturisation of components, coupled with new narrow-band radio transmitters and receivers makes wirefree alarm systems quite on a par with their hardwired counterparts.
