A device includes a housing, a tamper switch supported at the housing, and a tamper actuator receivable at the housing. The tamper actuator is movable between a tamper disabled position and a tamper enabled position. In the tamper disabled position, the tamper actuator is fixed in place at the housing. In the tamper enabled position, the tamper actuator is configured to move relative to the housing between a tamper switch engaged position and a tamper switch released position.

Selectively enabled tamper detection

Systems and methods for measuring and modifying an input voltage provided to a control panel are provided. Some systems can include measuring the input voltage provided by a power supply, determining whether the input voltage is within a range of acceptable input voltages, transmitting, to the power supply, a modulated signal on a direct current line between the power supply and the control panel instructing the power supply to modify the input voltage, and generating a notification when the input voltage is outside of the range of acceptable input voltages.

Systems and methods for modifying input voltage received by a control panel

A monitoring system includes at least one detector having a housing that carries at least one ambient condition sensor. Control circuits carried by the housing are coupled to the at least one ambient condition sensor. A separate audio input transducer carried by the housing is coupled to the control circuits, wherein the control circuits include signal processing circuits coupled to the separate audio input transducer. The signal processing circuits cancel predetermined audio received from the separate audio input transducer and output a processed speech signal that is coupled to speech recognition circuitry. The speech recognition circuitry recognizes selected speech to implement predetermined functions.

A method and apparatus wherein the method includes the steps of generating a globally unique identifier (GUID) for a security system appliance, saving a public key and private key of the security system appliance in a memory of the security system appliance, a manufacturer of the security system appliance generating a signed version of the GUID and the public key, saving the signed version of the GUID and public key in the memory of the security system appliance, the security system appliance sending a registration message including the signed version of the GUID and public key to a security system server and the security system server authenticating the security system appliance using the signed version of the GUID and public key of the security system appliance and a public key of the manufacturer.

System and method of using a signed GUID

A method and apparatus are provided. The method includes the steps of connecting a rerouting processor to a communication port of an alarm panel, the connected processor capturing an alarm notification sent from the alarm panel through the communication port, said alarm notification including a destination telephone number of a first central monitoring station, the connected processor altering the captured alarm notification by deleting the destination telephone number from the captured alarm notification and the connected processor routing the altered alarm notification to a second central monitoring station that is different than the first monitoring station.

Alarm panel phone number capture and substitution

A system and method for communicating between a base and a remote device in a security system. The base receives an audio signal from a telephone network via a panel and then frequency modulates the audio signal at a carrier frequency to generate an FM signal. The remote device receives the FM signal from the base, determines a phase error signal representing the phase error between the received FM signal and an output signal of a voltage controlled oscillator, determines a difference between the carrier frequency and a center frequency of the voltage controlled oscillator, and, if there is a difference, then changes the center frequency of the voltage controlled oscillator to match the carrier frequency of the FM signal.

Security system with dynamic range enhancement for FM demodulation

A half-wave rectifier including an input port for receiving an incoming AC signal, an output port for outputting a half-wave rectified signal, an operational amplifier including inverting and non-inverting input terminals and an output terminal, the inverting input terminal connected to a ground reference and a non-inverting input terminal coupled to a negative feedback loop and a first resistor. The negative feedback loop including a second resistor coupled between a first node and a second node, the first node coupling the output terminal and the output port and the second node coupling the non-inverting input terminal and the second resistor. A capacitor is coupled to the input port and in series with the first resistor.
