Ac Power

Ac power is a form of electricity that is supplied from a plug-in transformer and is measured by the number of cycles it produces.

Access Control

access control is a form of security that restricts access to unauthorized users at predetermined checkpoints, usually doorways, or building lobbies. varying levels of access can be granted to personnel based on their needs and responsibilities.

Affiliated Monitoring

One of the larger wholesale monitoring companies in the united states, affiliated monitoring is characterized by its strong focus on the pers industry and pers event, catalyst.


An alarm can take both audible and visual forms to emit warnings to device users and alarm monitoring centers alike. alarms typically use loud and bright signals to avoid any confusion about whether or not there is an emergency.

Alarm Battery

Batteries can be used to power wireless alarm devices or security system control panels as backup power sources or primary sources. lithium batteries generally last longer than traditional alkaline alarm batteries.

Alarm Communication Path

The alarm communication path is the method a security system uses to communicate with a monitoring center. the plain old telephone service (pots) is the most common type of communication path that is used in security systems.
with advances in wireless technologies, other more secure communication paths such as cellular alarm monitoring are gaining popularity. internet protocol (ip) monitoring and dual path (cellular/ip) monitoring are some other communication paths that do not require a hardwired telephone line to be present at the property.

Alarm Device

In addition to the central panel where the security system is controlled, additional peripheral devices can be attached to the panel to detect emergency events and communicate them to the panel. some examples of devices are glass break sensors, door sensors and fire detectors.

Alarm Event

Once an emergency has been detected by a device, an alarm event is communicated to the control panel which forwards the signal to the central station.

Alarm Factor

An indicator that measures the health of an installation company's signal traffic. calculated weekly or monthly, an alarm factor is calculated by dividing the total number of accounts by the number of signals received by the monitoring center. companies that have a poor alarm factor may have installation issues or poor customer education systems in place.

Alarm Monitoring

Devices that track emergency situations can be connected to an alarm monitoring service which ensures that users are protected at all hours of the day by a central station operator.

Alarm Notification Device

One option security systems can include is an audible or visual alarm system that alerts people in a designated area. they are designed to be exceptionally loud and/or bright in order to remove any doubt about the nature of the alarm (e.g. sirens, speakers, strobes, etc.).

Alarm Signal

The first event that occurs, once an emergency has been detected, is initiated by an alarm device and transmitted by a control panel to a monitoring center. depending on the type of signal and account instructions, the operator will either call the subscriber or alert emergency services immediately.

Alarm Transmitter

Within the alarm device itself, another electronic device wirelessly transmits an alarm signal from an alarm device to a burglar alarm control panel. without the transmitter, the detection has no communication path to take.

Alarm Verification

Once an alarm is received by the central station, depending on the type of alarm, it must first be verified to ensure that an actual intrusion has taken place. one way operators can investigate is by leveraging an integrated video feed, which utilizes cameras that are installed in the same area as the alarm device so the central station operators can review the feed to determine what caused the alarm.
audio verification utilizes microphones that record audio which operators can review. call verification requires that an operator connect with a user to verify the alarm.

Ambient Temperature

Within a building space, the ambient temperature measures the environment surrounding an alarm device. in addition to home and commercial automation, temperature measurement is crucial for environmental monitoring where regulation compliance maintains the life of a product.


Local police officers are responsible for the investigation and apprehension of people who break laws. an apprehension is the arrest of a suspected criminal which results from the police department responding to an alarm.


In order to activate an alarm system, it must be "armed." in other words, so that a device can be armed, it must be activated so it is ready to detect an alarm event.

Arming Sequence

The arming sequence is the amount of time a security system takes to go from its armed status to its disarmed status.

Artificial Intelligence

Also known as machine intelligence, it is a form of intelligence that is demonstrated by machines. essentially, machines using artificial intelligence are capable of perceiving its environment and taking actions that help it to achieve a goal.

Audible Alarm

Once a predetermined parameter has been broken, and a signal has been sent to the alarm panel, an audible alarm emits a high pitched sound to alert people in a given area that an emergency situation has occurred or is occurring.

Audio Verification

Once an alarm has been triggered, an operator can use recorded audio from the area an alarm was triggered in order to investigate its validity. this does not always paint a clear picture since burglars do not need to make a lot of noise when entering a premises.

Authority Level

An authority level is a designation that is assigned to each user on a device which determines the specific functions or areas a user can access. for example, not all users are allowed to change core functions in an alarm panel, just as much as not all people are allowed to access specific areas like homes or areas of an office building.

Auxiliary Panic Keys

Programmed to activate different types of distress signals (burglar, fire, hold up/panic, medical). always work, regardless of whether or not the main security system is armed.


Babysitter Code

When someone other than a primary user needs to disarm a system when visiting, a lower-authority user code can arm the security system anytime, but can only disarm the system if the babysitter code was used to arm it. . once the system has been armed with a normal user code the babysitter code will no longer function to disarm it.

Backup Alarm Battery

In the event that a device loses connection to electricity, a back-up alarm battery ensures that a security system will continue to work after losing ac power. back-up alarm batteries typically power a system for a 24-hour period.


In an internet connection, bandwidth is the capacity of the transmission medium stated in bits per second and as a frequency. it can also be the amount of data that can be transmitted in a fixed amount of time. for digital devices, the bandwidth is usually expressed in bits per second (bps) or bytes per second. for analog devices, the bandwidth is expressed in cycles per second, or hertz (hz).

Biometric Code

Used on some locks; provides greater security than a numbered code on a standard lock. only the individual with the exact fingerprint, dna, or different type of identifying input can open the lock.


An alternative to using passcode access methods, biometrics is the mehtod of identifying an individual based on physiological or behavioral inputs such as matching eye patterns, fingerprints or voice tone.


Originally designed to protect virtual currency transactions, blockchain introduces unparallelled security features that can be leveraged in iot devices. it uses multiple networks to create an coded message that requires network consensus before it can be changed.


Someone who gains unauthorized access to a residential or commercial area to steal items of value.

Burglar Alarm System

An electronic system that consists of alarm devices that are connected to a control panel through a low-voltage, hardwire or narrowband rf wireless signal. a burglar alarm system can be monitored professionally by a central station or individually by the user.


An unauthorized entry of a secure location which results in the damage and/or theft of property.

Business Security

Securing the property and assets of a business or organization using burglar alarm systems, access control systems, and/or video surveillance. businesses, due to the large number of people using the security systems, often need multiple user codes and sometimes utilize scheduled arming and disarming.


To bypass a zone is to remove it from service by directing the security system to ignore a specified area. a bypass can be automatically removed when the security system is disarmed.


Caa - California Alarm Association

The california alarm associaiton is a body of individuals who contribute to the maintenance and improvement of the security alarm industry. in addition to the scholarships, training and group improvement initiatives, the caa works with legislative organizations to take appropriate legal action for the benefit and wellbeing of security alarm companies.

Call Verification

After an alarm signal is received in the central station, the operator makes several call verifications to investigate whether or not a received signal is due to a false alarm. the first call made is usually to the site where the alarm occurred. if the call is answered, the operator asks for a password from a pre-assigned person. if there the call goes unanswered, depending on local dispatch regulations, a call will be made to have police investigate the situation. if the local regulations require it, the operator will try several other phone numbers to try and reach someone. in some jurisdictions, operators are required to call at least two different phone numbers before requesting dispatch. this is called enhanced verification, and it has been found to significantly reduce false alarms.

Caller Id Injection

In order to have calls from the wholesale monitoring center appear to come from the customer-facing company, the wholesale monitoring center can provide caller id injection. this service helps increase answer rates and improve customer experience because the name correlates with the company the customer chose to work with.

Carbon Monoxide Detector (Co)

A device that detects the presence of the toxic gas carbon monoxide, a colorless and odorless compound which is lethal at high concentration. if enough carbon monoxide is detected, the device sounds an alarm, giving people in the area a chance to ventilate the area or safely leave the building. carbon monoxide is produced from incomplete combustion of fossil fuels.

Category 5 (Cat-5) Wire:

A twisted cable that is designed to withstand a high signal rate. it is commonly referred to as cat-5 wire and has since been superseded by the “category 5e” specification. the cat-5 cable is most frequently used to construct computer networks, and is also used to carry additional signals such as basic voice services, token ring, and atm data.

Cellular Alarm Monitoring

A type of alarm communication path that uses a digital cellular network to send alarm signals from the control panel to a monitoring center's cellular receivers. this type of alarm monitoring requires a digital cellular communicator that is hardwired into the security system and a cellular monitoring contract. cellular monitoring does not require phone lines, and there is no chance of the purposeful or accidental cutting of your alarm communication line. therefore, cellular monitoring is one of the most reliable ways to monitor a security system. cellular devices can also be mobile, providing an opportunity for the central station to monitor the physical location of the devices as necessary.

Central Monitoring Station

The operations center where signals are received and emergency action is taken. central stations typically monitor security systems, pers devices, fire and gas alarms, as well as a collection of internet of things (iot) devices

Central Station Operator

See tma - the monitoring association.



A sensor that is dedicated to identifying significant changes in environmental factors such as: gas levels, temperature, brightness and sound frequencies. detectors that belong to a monitored system always communicate to a central panel.

Digital Cellular Communicator

An electronic device that delivers a cellular connection between a security system and the central monitoring station. cellular communicators have built-in sim cards and leverage pre-existing wireless networks. it sends alarm signals from the security system to the central monitoring station without the need for a pots line. because of its lack of wires, a cellular communicator is much more secure than a traditional wires that can be cut.

Digital Subscriber Line (Dsl)

A related collection of technologies that transmits data through a local telephone network. dsl can be used at the same time–and on the same telephone line with regular telephone transmissions–as it uses high frequency, while telephone lines use low frequency. alarm communications can be transmitted over dsl but they require a special filter to prevent interference between the two.


The action of turning off the control panel of a security system. in this stage, none of the sensors will be monitoring alarm events like opening doors, breaking glass, and more.


The operating service that relays event information to emergency responders like the fire department and the police department. dispatch is also the action that is made which requests emergency assistance.

Do It Yourself (Diy) Security

A more contemporary form of security system that does not require extensive installation skills such as running wires, configuring complex systems or setting up professional monitoring services. diy systems are the preferred style of security for residential users since the systems are mobile and do not require professional monitoring.

Dual Interface Poll (Dip)

A collection of switches that allow you to configure the circuit board of an emergency detection device or alarm control panel in order to activate and change its functionality.

Dual Path (Cellular/ip) Digital Communicator

An electronic device that provides both internet protocol (ip) and cellular connection points for alarm monitoring purposes. this type of communicator hardware typically uses the ip path as the primary method because an ip signal can be constantly polled for connectivity. as soon as the ip signal is lost, the alarm communicator automatically switches to the cellular pathway. that method requires the use of a built-in sim card to communicate over an existing wireless network. a cellular/ip communicator sends alarm signals from the security system to the central monitoring station without the need for a pots line. dual path monitoring is more reliable than monitoring over a phone line because it has redundant signal communication paths.

Duress Code

A silent method of alerting the monitoring center operator that the user is in need of emergency help without letting the perpetrator know. using this method, the user enters a four digit code into the control panel that tells the operator to send emergency help immediately. from the perpetrator’s perspective, the code simply disarms the system.

Enhanced Call Verification

A form of alarm verification where a central station operator places two phone calls before requesting emergency dispatch services. ecv is quickly being adopted by jurisdictions across the country since it has proven to be an effective form of false alarm reduction and helps lower the costs that cities and states waste responding to false alarms.

Entry/ Exit Delay

When a user enters an area that is monitored by a security system, a built-in delay begins counting to give the user time to enter the required passcode. implementing entry/exit delays helps to avoid setting off alarms when it’s not necessary. predetermined delays can last 15 to 120 seconds before the alarm signal is sent to the central station.

Entry/ Exit Zone

A zone in a home or commercial space that is used to enter or exit the premises. in homes, these zones monitor front and back doors as well as garage doors. for commercial spaces, these zones usually protect the front door and back doors.

Environmental Monitoring

environmental monitoring is a form of monitoring that measures gas levels, light, temperatures or water presence. each type of sensor measures environmental factors that signal undesired changes and even threats to human health. some examples of environmental sensors can be found in hospital refrigerators to protect medication, mine shafts to check for deadly gases, manufacturing plants for regulation compliance and even homes to check for flooding.

Esx - Electronic Security Expo

As one of the largest tradeshows in the electronic security industry, esx delivers education, entertainment and keynote speakers. one of its biggest selling points is being the show that's big, but not too big. in comparison to shows like isc west or ces, esx seems to meet the middle ground in size that many attendees look for.

Gps Monitoring

A form of monitoring that identifies the location of a user’s device after an emergency event. gps monitoring not only leverages the existing global positioning system network of orbiting satellites, but can also use cellular networks to track a user’s location. in a typical monitoring scenario, cellular locating is more accurate because of its ability to track users inside of buildings and even under cloudy skies.


Heat Detector

A burglar alarm or fire alarm device that detects a preset high temperature or a rapid rate-of-rise (ror) in temperature. heat detectors can be either electrical or mechanical in operation. the most common types are thermocouple and electro-pneumatic, both of which respond to changes in ambient temperature. if the ambient temperature rises above a predetermined threshold, then an alarm signal is triggered. heat detectors are better than smoke detectors for areas where smoke would normally be found such as a kitchen or smoking lounge, since they do not produce as many false alarms.

Hidden Camera

A security camera that is strategically placed to avoid detection by intruders. the camera is considered to be "hidden" when it is not visible to the subject being filmed, or is disguised as another object. hidden cameras have become popular for household video surveillance and can be integrated with common household objects such as smoke detectors, clock radios, motion detectors, ball caps, plants, and cell phones. hidden cameras may also be used for commercial purposes.

Holdup Switch

A form of panic button that is similar to a duress code without the complexity of a passcode. when a holdup switch is activated, it sends an alarm to the central monitoring station and requires the immediate dispatch request. these devices are usually mounted underneath a checkout counter or underneath a bank teller’s workstation so that a person in distress can discreetly activate it. when a holdup switch is activated, it does not create an audible alarm so that the intruder is not made aware.

Home Security

A form of protection from burglaries, intrusions and environmental hazards that uses devices to detect movement, changes in environmental statuses, unauthorized entryway access or the breaking of glass.

Hybrid Monitoring

An alternative approach to central station monitoring, hybrid monitoring gives security companies with in-house central stations access to industry-leading alarm automation and central station redundancy.

Opening/ Closing Reports

A security system that is programmed for openings and closings will send a signal to a central monitoring station every time the system is armed or disarmed. the central monitoring station can then print out a report of these openings and closings so that the user can monitor the use of his or her security system.

Operating Procedures

See “standard operating procedures”

Optical Detection (Photoelectric)

A type of smoke detection that is better at detecting smoky or smoldering fires as it detects changes in light. when a room fills with smoke there is less light available to the optical sensor in the smoke detector and an alarm is triggered. this type of smoke detector is not as good at detecting flaming fires because there won’t be enough of a light change to set off the device.


Panic Alarm

A feature in many security systems that allows the user to request an immediate dispatch. with the panic alarm feature, no call verification is needed since the user has to enter a passcode before the alarm is sent to the central station.


A segmented section of a security system. users can setup partitions so that one area of the system can be armed while the other areas stay unarmed. for instance, an inventory room can be partitioned from the rest of the store so that while people are working, the main areas are unarmed and the inventory room stays protected.

Passive Infrared Motion Detector (Pir)

An alarm device that measures infrared (ir) light radiating from objects in its field of view to sense motion and activate an alarm. once the pir motion detector is installed, it settles into a normal state with a normal temperature. apparent motion is detected when an infrared source with another temperature, such as a human, passes in front of the pir detector and changes the normal temperature causing an alarm.


An area that is usually assigned to all exterior sensors and contacts connected to doors and windows. the idea behind protecting the perimeter of a home or business is that intrusions can be detected as soon as possible. with interior protection, users don’t receive an alarm until the intruder walks in front of an interior protection sensor.

Pers Monitoring
