Alarm sensor

Abstract: Methods, systems, and products notify of alarms in security systems. Sensor data is received from an alarm sensor, and an alarm controller determines an alarm condition. Video data associated with the alarm sensor is retrieved. An alarm message may be sent over a wireless network connection, while the video data may be sent over a wireline broadband connection.

Abstract: The invention is an alarm system which transmits audio and video signals using radio frequency of a monitored enclosure to a remote location by means of wireless technology when said alarm system is triggered by an alarm sensor. The RF transmission of the audio visual signal will continue until the condition which triggered the alarm sensor ceases or until the alarm system is reset either using the system alphanumeric keypad or by the remote location using a keypad of a telecommunications device.

Abstract: A security alarm system including multiple, zone distributed audio monitors and alarm sensors which report and verify detected alarms and communicate with a system controller and central station Ambient audio is continuously and selectively recorded in a storage memory and is replayable to verify alarms detected at the alarm sensors During pre-alarm conditions, all audio inputs are summed and recorded During an alarm state, the audio input of the audio monitor physically closest to a reporting alarm sensor is automatically selected and the post-alarm audio activity is recorded only for that sensor The central station is able to selectively communicate via a phone link with each audio controller and engage in half duplexed voice communication with the alarm site, remotely playback and listen to the locally recorded audio data, or program each audio controller The monitored audio data is stored in RAM storage in discreet segments corresponding to predetermined periods of pre-alarm and post-alarm data

Abstract: A system for transmitting and verifying alarm signals over a TCP/IP network includes: an alarm panel hosting an alarm client and verification server and connected to at least one alarm sensor, alarm verification means and a TCP/IP network, an alarm monitor server and a verification station connected to each other and to the TCP/IP network. If the alarm client detects an alarm situation, it transmits an alarm signal to the alarm monitor server. The alarm signal contains information on how to contact the verification server. If it is necessary to verify the alarm signal, the alarm monitor station sends the alarm verification station a verification request containing the contact information for the verification server. The alarm verification station contacts the verification server and obtains the verification information available from the alarm verification means.
