> Wireless Alarm System
Having a wireless alarm system installed in your home is one of the best ways in implementing home security. Wireless alarm system has two ways of transmitting its connection. It is either connected by radio frequency or infrared light rays. Wireless home alarm systems can either be monitored or unmonitored. Monitored wireless alarm systems transmit signals to a monitoring station of the security company as the alarm is triggered. More often these alarms are not audible. In unmonitored wireless alarm systems, a very loud alarm (more often a siren with flashing lights) is set off but does not notify any monitoring station.
The heart of wireless security alarm systems is the control panel, which is usually located on the basement or on a hidden panel. In wireless alarm systems, the doors and windows are installed with two magnetic switches. One magnetic switch is installed on the door frame or window frame and another is installed on the door or window so that if the switch is moved out of its position, an alarm is triggered.
On hallways and large rooms, motion sensors are installed. However some wireless security alarm systems use infrared sensors, motion detectors or temperature sensors. Infrared sensors and temperature sensors detect body heat, while motion detectors detect movements on the room or hallway. If any one of these sensors is triggered, a signal is then transmitted to the control panel which analyzes it to determine if the intrusion is unauthorized or not. Wireless security alarm systems use keypads to disarm or arm the system. These keypads are normally found near the main entrance.
Wireless security alarm systems have six advantages over wire security alarm systems. The first one is that wireless security systems are easy to install. You can install one yourself unlike the wired systems wherein proper installations of wires are needed. Second, you can install them anywhere since the usage of wire is not required. Third, wireless systems are flexible; unlike their wired counterparts, wherein you have to review the wiring plans before any altering of the system. Fourth, it has a cleaner look. In a wired system, you have wires running all over the house. Fifth, wireless security alarm systems are more difficult to tamper. Wired security systems can easily become un-operational if the wires are severed intentionally or not. Lastly, wireless security alarm systems are easy to maintain. Wire security systems are bulky, hence, requires more maintenance while in a wireless security system, the only thing you need to maintain is its power supply that usually are the batteries.
Always remember to check your batteries in order for your wireless security systems to be reliable.
The History of ADT and ADT Alarm Systems
Summary: Youve heard about ADT as the forefront of security and monitoring technology but what you might not know is the humble origins of ADT as a Telegraph Messenger Service.
If youve heard about ADT as the forefront of security and monitoring technology for over 125 years, then you should know as well that their security systems are highly sophisticated, and that ADT offer unparalleled service and their superior ADT alarm systems are what you’ve come to expect.
But what you might not know is the humble origins of ADT as a Telegraph Messenger Service. So how would an ADT alarm system fit in the picture? Read on and follow the path the ADT alarm system took in history
Though the American District Telegraph (ADT) is formed through the affiliation of 57 district telegraph delivery companies in around 1874, it is with the advent of advanced Call Boxes and multi-signal electric protection system in the early 1890s that ADT became a preeminent security protection company. Before, ADT function much as their name implies, telegraph service. These call boxes (electric signal devices) allow interactive communication between customers and ADT. And as an outcrop of the business and to further the development of the call boxes innovation, ADT started providing security and protection services to a varied clientele. Therefore, you can safely assume that the parent of ADT alarm system would be the call boxes.
These multi-signal Call Boxes allowed watchmen at businesses to do more than just signal for police or fire department assistance, they also allow watchmen to send a specific signal to the ADT office, at designated times, to let the monitoring office know that all was well. And if a district office didn’t receive its scheduled signal, ADT protocol was always to assume something is amiss, and help was promptly dispatched.
It was in 1910 to 1930, under the leadership of AT&T that ADT began to really shed its telegraph messenger service roots to concentrate fully on signal, security and protection service. In a very short time, ADT became synonymous with emergency call systems. It was also this time when the respected line of ADT alarm systems went out of production.
When war broke out, the resulting domestic manpower shortage drove the demand for better ADT alarm systems that would not only detect problems, but signal an alarm automatically. In essence, a cry for an automated ADT alarm system was made. Because ADT provided a unique integration of systems and services, it was a logical step for the company to create these automatic systems. As a result, automated ADT alarm systems such ass the Teletherm automatic fire detections system, the Telewave automatic intrusion system surfaced.
The following decades ADT continued the technological breakthroughs of the century, introducing a whole slew ADT alarm systems such as the wireless Safewatch systems, including the Plus RF and the Custom RF models; the state-of-the-art integrated Focus system line, and a variety of access control and closed circuit television (CCTV) products.
