The police receive a tremendous number of false alarms from burglar alarms. In fact the security industry reports that over 98% of such alarms are false ones. Accordingly, the police give very low priority response to burglar alarms and can take from twenty minutes to two hours to respond to the site. By contrast, the video analytic-detected crime is reported to the central monitoring officer, who verifies with his or her own eyes that it is a real crime in progress.

Residential burglar alarms can be caused by improper arming and disarming of the system, power outages and weak batteries, wandering pets, and unsecured doors and windows. In the U.S. false alarms cost police agencies up 6.5 million personnel hours, according to the International Association of Chiefs of Police. A 2002 study by the U.S. Justice Department estimated the cost of false alarms to be as high as $1.5 billion. Due to this cost, many cities now require permits for burglar alarms, have enacted verified response protocols, or have introduced fines for excessive false alarms.

This style of tamper resistance is most commonly found in burglar alarms. Most trip devices (e.g. pressure pads, passive infrared sensors (motion detectors), door switches) use two signal wires that, depending on configuration, are normally open or normally closed. The sensors sometimes need power, so to simplify cable runs, multi-core cable is used.

Some systems are designed to detect problems internally, such as low or dead batteries, loose connections, phone circuit trouble, etc. While earlier nuisance alarms could be set off by small disturbances, like insects or pets, newer model alarms have technology to measure the size/weight of the object causing the disturbance, and thus are able to decide how serious the threat is, which is especially useful in burglar alarms.

The term "false alarm" is actually a misnomer, and is regularly replaced by the term "nuisance alarm". When a sensor operates, it is hardly false, and it is usually a true indication of the present state of the sensor. A more appropriate term is nuisance, indicating that the alarm activation is inconvenient, annoying, or vexatious. A prime example of this difference is burglar alarms being set off by spiders.

Passive glass break detector A glass break detector is a sensor used in electronic burglar alarms that detects if a pane of glass is shattered or broken. These sensors are commonly used near glass doors or glass store-front windows. Glass break detectors usually use a microphone, which monitors any noise or vibrations coming from the glass. If the vibrations exceed a certain threshold (that is sometimes user selectable) they are analyzed by detector circuitry.

A major problem on the estate in the past was the presence of joyriders exploiting the straight main roads that ran the length of the estate. To tackle this, the HAT employed a traffic calming scheme in April 1998. This was done by installing speed bumps, mini- roundabouts and narrowing road lanes. An issue for residents was securing their property from thieves and so the HAT provided burglar alarms and car steering locks.

Ultrasound can be used for measuring wind speed and direction (anemometer), tank or channel fluid level, and speed through air or water. For measuring speed or direction, a device uses multiple detectors and calculates the speed from the relative distances to particulates in the air or water. To measure tank or channel liquid level, and also sea level (tide gauge), the sensor measures the distance (ranging) to the surface of the fluid. Further applications include: humidifiers, sonar, medical ultrasonography, burglar alarms, non-destructive testing and wireless charging.

Typical alarm systems are designed to not miss true positives (real crime events) and to have as low of a false alarm rate as possible. In that regard, burglar alarms miss very few true positives but have a very high false alarm rate even in the controlled indoor environment. Motion detecting cameras miss some true positives but are plagued with overwhelming false alarms in an outdoor environment. Rule-based analytics reliably detect most true positives and have a low rate of false positives but cannot perform in active environments, only in empty ones.

Retrieved July 17, 2010. Starfish Prime caused an electromagnetic pulse (EMP) that was far larger than expected, so much larger that it drove much of the instrumentation off scale, causing great difficulty in getting accurate measurements. The Starfish Prime electromagnetic pulse also made those effects known to the public by causing electrical damage in Hawaii, about away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms, and damaging a telephone company microwave link. The EMP damage to the microwave link shut down telephone calls from Kauai to the other Hawaiian islands.

Older electric doorbell An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound. Electric bells have been widely used at railroad crossings, in telephones, fire and burglar alarms, as school bells, doorbells, and alarms in industrial plants, since the late 1800s, but they are now being widely replaced with electronic sounders. An electric bell consists of one or more electromagnets, made of a coil of insulated wire around an iron bar, which attract an iron strip armature with a clapper.

In July 1962, the US carried out the Starfish Prime test, exploding a bomb above the mid-Pacific Ocean. This demonstrated that the effects of a high-altitude nuclear explosion were much larger than had been previously calculated. Starfish Prime made those effects known to the public by causing electrical damage in Hawaii, about away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms and damaging a microwave link. Starfish Prime was the first success in the series of United States high-altitude nuclear tests in 1962 known as Operation Fishbowl.

Pittway Corporation was a diversified holding company best known as a manufacturer and distributor of professional and consumer fire and burglar alarms. In 1962, Neison Harris became president, after having worked as an executive at Gillette, at a time when the company was transitioning from a trolley operating company to a diversified concern running multiple businesses. Pittway completed its divestment out transportation in 1964 through sale of trolley operations to the Port Authority of Allegheny County, receiving more than for the operations.The phrase used in the source is "...Port Authority Transit took over its people-carrying business in a condemnation proceeding...." That would seem to imply that the divestment was involuntary, but need better citation to get a clearer picture.

A modern "rapid deploy" security smoke machine The market for using security smoke as a theft prevention tool came about because of an increase in the ability of thieves to circumvent existing physical security measures, often by simply raising the level of violence utilised to gain entry. Burglar alarms often have a delay of several minutes before police or private security are able to respond, meaning a well organised criminal has a period of time in which to enter and take what they like. Closed-circuit television and recording devices have been nullified as thieves routinely hide their identities. The security smoke market developed as an alternative security method, designed not to deter entry, but to prevent loss if a thief did gain access.

Soft security usually refers to security that protects something from harm in quiet and unobtrusive ways, often invisibly and after the fact, rather than with visible barriers before the fact. Soft security can refer to immediate security measures, such as silent burglar alarms or motion detectors, but often refers to more elaborate social security systems such as the "moral network" in a tightly-knit community — for example, a cluster of friends on a busy city street. The term has gained widespread use in wiki communities, notably MeatballWiki. The differentiation between "soft security" and "hard security" was first made by Rasmusson and Jansson who used the term hard security for traditional mechanisms like authentication and access control, and soft security for social control mechanisms.

The view of military-focused historians is that licensing restricted the number of fortifications that could be used against a royal army. The modern view, proposed notably by Charles Coulson, is that battlements became an architectural status-symbol much sought after by the socially ambitious, in Coulson's words: "Licences to crenellate were mainly symbolic representations of lordly status: castellation was the architectural expression of noble rank". They indicated to the observer that the grantee had obtained "royal recognition, acknowledgment and compliment". They could however provide a basic deterrent against wandering bands of thieves, and it is suggested that the function of battlements was comparable to the modern practice of householders fitting highly visible CC-TV and burglar alarms, often merely dummies.

For distant sites, a dry pair of telephone wires called a DC loop, private line- or RTO circuit (Radio Telephone Operation) was leased from the telephone company. Older burglar alarms used the same type of DC wiring from subscriber location to the alarm office. As pair gain electronics and point-to-point microwave radio links came into widespread use throughout the public switched telephone network, telephone companies filed tariffs to eliminate their past responsibility of providing leased circuits with direct current continuity. If the base station were located across town in an area served by a different telephone exchange, the only available circuits reaching the distant exchange might be a single voice-grade channel in a D-4 channel bank on a DS-1 or a single microwave radio baseband channel.

Borowski, Greg J. "Alderman forms Rapid Response Team; McGee says group will combat 'domestic terrorism'", Milwaukee Journal Sentinel, September 1, 2004, p. 1-B In a press release issued at the time, McGee said: "The Rapid Response Team would be dispatched immediately when serious disputes between neighbors are reported, when there are complaints about police brutality and when residents and business owners have serious concerns about police response to burglar alarms. The team will respond to community concerns and will be on the scene to collect and exchange information and to document what's going on." The group, which stated its intention to make citizen's arrests, was variously described as an initiative to address black-on-black crime, a monitoring program to deal with police brutality and an information source for north side residents.

The resulting transient electric fields and currents that arise generate electromagnetic emissions in the radio frequency range of 15 to 250 megahertz (MHz, or fifteen million to 250 million cycles per second). This high-altitude EMP occurs between 30 and 50 kilometers (18 and 31 miles) above the Earth's surface. The potential as an anti- satellite weapon became apparent in August 1958 during Hardtack Teak. The EMP observed at the Apia Observatory at Samoa was four times more powerful than any created by solar storms , while in July 1962 the Starfish Prime test, damaged electronics in Honolulu and New Zealand (approximately 1,300 kilometers away), fused 300 street lights on Oahu (Hawaii), set off about 100 burglar alarms, and caused the failure of a microwave repeating station on Kauai, which cut off the sturdy telephone system from the other Hawaiian islands.

The term “false alarm” refers to alarm systems in many different applications being triggered by something other than the expected trigger- event. Examples of this those applications include residential burglar alarms, smoke detectors, industrial alarms, and signal detection theory. The term “false alarm” may actually be semantically incorrect in some uses. For example, a residential burglar alarm could easily be triggered by the residents of a home accidentally. The alarm is not necessarily false – it was triggered by the expected event – but it is “false” in the sense that the police should not be alerted. Due to this problem, false alarms can also be referred to as “nuisance alarms.” Sociologist Robert Bartholomew explains that there are many negative effects of false alarms, such as "fear, havoc, disruptions to emergency services, and wasted resources." Health and safety can also be effected, as they can cause anxiety and encourage people to race toward an alarm or away from it, which can result in accidents in the panic.
