A alarm is a system designed to detect intrusion – unauthorized entry – into a building or other area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (thefy) or property damage, as well as personal protection against intruders. Car alarms likewise help protect vehicles and their contents.Prisons also use systems for control of inmates.

Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance (CCTV) systems to automatically record the activities of intruders, and may interface to access control system for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multiarea systems with computer monitoring and control. It may even include two-way voice which allows communication between the panel and Monitoring station.

After locking the door, do you walk away backwards, unwilling to tear your protective gaze away? Instead of reluctantly easing into your car, do you eventually give up, running back to your house to stand guard over your property? If you want to be able to actually see what happens while you're away, security cameras may calm your nerves. Video surveillance allows you to monitor or record activity in and around an area for many different reasons. For example, parents might want to watch over a sleeping child and lessen the risk of a dangerous fall from the crib. But a security camera system around the house can see people who approach the front door and maybe even catch a criminal in the act of breaking in. There's a wide variety of security cameras available. Some are large and out in the open, and might serve simply to deter criminals from even approaching a home, while others are tiny and meant to stay hidden from view. If you're considering setting up some type of video surveillance system in or around your home, there are a lot of questions to ask yourself before getting started.

    All home security systems work on the same basic principle of securing entry points, like doors and windows, as well as interior space containing valuables like art, computers, guns, and coin collections. Regardless of the size of your home, or the number of doors and windows or interior rooms a homeowner decides to protect, the only real difference is in the number of security components deployed throughout the home and monitored by the control panel.

    What is a security system?

    The most basic definition of any security system is found in its name. It is literally a means or method by which something is secured through a system of interworking components and devices. In this instance, we're talking about home security systems, which are networks of integrated electronic devices working together with a central control panel to protect against burglars and other potential home intruders. A typical home security system includes:
    • A control panel, which is the primary controller of a home's security system
    • Door and window sensors
    • Motion sensors, both interior and exterior
    • Wired or wireless security cameras
    • A high-decibel siren or alarm
    • A yard sign and window stickers

    Electrical Magnetic Door Locks

    Electrical Magnetic Door Locks An electromagnetic lockmagnetic lock, or maglock is a locking device that consists of an electronmagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail safe" or "fail secure". A fail-secure locking device remains locked when power is lost. Fail-safe locking devices are unlocked when de-energized. Direct pull electromagnetic locks are inherently fail-safe. Typically the electromagnet portion of the lock is attached to the door frame and a mating armature plate is attached to the door. The two components are in contact when the door is closed. When the electromagnet is energized, a current passing through the electromagnet creates a magnetic flux that causes the armature plate to attract to the electromagnet, creating a locking action. Because the mating area of the electromagnet and armature is relatively large, the force created by the magnetic flux is strong enough to keep the door locked even under stress.

    Emergency Switches

    Emergency Switches A kill switch, also known as an emergency stop (e-stop) and as an emergency power off (EPO), is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usual manner. Unlike a normal shut-down switch or shut-down procedure, which shuts down all systems in order and turns off the machine without damage, a kill switch is designed and configured to abort the operation as quickly as possible (even if it damages the equipment) and to be operated simply and quickly (so that even a panicked operator with impaired executive functions or a by-stander can activate it). Kill switches are usually designed to be noticeable, even to an untrained operator or a bystander. Most kill switches feature a Mollyguard, a removable, protective barrier against accidental activation (e.g. a plastic cover that must be lifted or glass that must be broken). Kill switches are features of mechanisms whose normal operation or foreseeable misuse might cause injury or death; industrial designers include kill switches because damage to or the destruction of the machinery is less important than preventing workplace injuries and deaths

    Two Way Radio

    Two Way Radio A two-way radio is a radio that can do both transmit and receive a signal (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel). Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies, handie-talkies, or just hand-helds. Two-way radio systems usually operate in a half duplex mode; that is, the operator can talk, or he can listen, but not at the same time. A push to talk or Press To Transmit button activates the transmitter; when it is released the receiver is active. A mobile phone or cellular telephone is an example of a two-way radio that can transmit and receive at the same time, i.e., in full-duplex mode. Full-duplex is generally achieved by the use of two different frequencies or by frequency-sharing methods to carry the two directions of the conversation simultaneously. Methods for mitigating the self interference caused by simultaneous same-frequency transmission and reception include using two antennas,or dynamic solid-state filters.
