If I own a small shop, and I had an alarm system and a silent alarm system with video cameras? and the box of authority should be eliminated, I guess the work of both alarms and cameras wouldnt. correct?
I am building plans for my dream house and want to have the latest tech cameras and alarms. but if a burglar simply damaged the electrical box that connects the electrical son on the side of the road from my house, would make it unnecessary alarms and cameras as there is no power?
No, unless the alarm and monitoring systems have been designed and installed by amateurs.
For years, the alarms have batteries included as standard, the battery life will vary depending on the level of security provided and how the system is maintained, but can generally power the alarm for several hours several days without mains power (it will operate normally during this time - reports and alarms, etc.).
Most surveillance systems use UPS (uninterruptible power supplies) for both cameras and DVR / VCR so that power outages do NOT stop recording. These are generally not as long as batteries for alarm systems (as they need much more power) but can vary between 30 minutes to several hours.
high-end homes often have generators and automatic transfer switches, and provide energy when the local decline of the power of the city.
I hope it's a little help.
Thus, the cameras have a backup, such as batteries or compaciters long life to keep in a blackout or by virtue of malice, when buying ask him about it.
