Wednesday, June 22, 2011Difference between wireless and wired security systemCrime rate is on a hill and the installation of security systems in homes and offices become mandatory. Thefts and robberies are so common these days that the home owner is left no choice but to equip their houses with good security systems to protect their families and their belongings. There are both wired and wireless security systems. While both have the same purpose, which is safety, but the technology used is different inSystems. Wireless systems, as the name implies, the wire is not necessary in this type of security system. The message is transmitted via radio signals to the master panel. If this range of security products has been launched, they were not only expensive but also unreliable. But as this technology has become popular, the quality has improved significantly and products must be reasonable. Security systems are easy to install wireless compared to wired system becauseThere is no need to change the wiring of the house. Security SystemIf you want to install a security system wired, you need to set a position that is close to some power source that is not necessary for the wireless system. So, there is no need to rush to tear the wall or dig the soil around the wires. However, you must replace the batteries to operate the security system. The main ingredients used in these systems are the same control panel, sirens, touchpad, which hasSensors and motion detectors in security, as well as wired. However, the system relies on wireless technology to transmit radio signals generated by the motion close to doors or windows. Motion and vibration sensors also allow the control signals transmitted on the same panel technology. Wireless systems are equipped with some standard equipment, including cameras, sensors and recording devices, motion activated lights for interior and exterior of the house andBreaking vibration sensors to search for a window or door seen. There are some high-end systems, smoke detectors and carbon monoxide detectors as well. Today, wireless alarm systems are reliable and convenient. Before you decide to install one, however, when you want maximum security and ensure that the security system upgrade, if necessary, in future, because if you decide to protect some other areas of your property, you may need to deleteexisting wireless systems and installation.
