If you are looking for 100% wire-free home video monitoring, the new Arlo Pro Wire-free HD Security Camera System has you covered. One of the great features of the Arlo Pro System is the new and improved Arlo Pro Base Station. The Arlo Pro Base Station features a smaller look as well as a host of useful new features. For an added level of protection for unexpected situations in which you would need to take action right away, the Arlo Pro Base Station features an extremely loud siren that is rated at 100+ decibel loudness.
Anything in the range of 140 decibels, like a jet engine, is an immediate danger to your hearing. Exposure could create acoustic trama resulting in immediate deafness. Around 125 decibels, roughly as loud as a firecracker, is refered to as the pain threshold. It's the point where your ear interpert the level of sound as physically painful. Prolonged exposure at this level is very dangerous. The average rock concert is 120 decibels. At that volume hearing damage occurs in 7.5 minutes.
