Abstract: A vibration sensor for construction projects has a housing, a low range accelerometer and a high range accelerometer disposed in the housing, and an analog-to-digital conversion circuit connected to the low and high range accelerometers. The low range accelerometer may have a noise floor below 0.0248 g across frequencies up to 1 kHz, especially between 1 Hz and 315 Hz. The high range accelerometer has a maximum acceleration equal to or greater than 50 g across frequencies up to 1 kHz, especially between 1 Hz and 315 Hz.

Abstract: A security system includes at least one audio sensor and an alarm panel that transmits alarm report data through a communications network to at least one alarm receiver located at a central station remote from the premises that receives the alarm report data transmitted from the alarm panel through the communications network. A line card receives the alarm report data. An alarm receiver processor receives and processes regulated alarm report data in accordance with Underwriter Laboratories 1610 requirements. The line card is operable for receiving non-regulated alarm report data that is not regulated in accordance with Underwriter Laboratories 1610 requirements. The line card includes a secondary communications channel interfaced to a central station automation system and routes the regulated alarm report data to the central station automation system over the secondary communications channel and bypasses the alarm receiver processor.

Abstract: A method for interacting with customers is disclosed herein. The method involves creating a service ticket for services to be performed at a customer's site, dispatching a technician to the site, emailing to the customer a notification stating that the technician is on route to the site, transmitting information to the customer. This information may include a service ticket reference number, a service requested by the customer, the name of the technician, a photo of the technician, a listing of the technician's qualifications and/or certifications, a map showing the technician's location and/or the route being followed by the technician, and the technician's estimated time for arrival at the customer's site.

Abstract: A security system includes at least one audio sensor and alarm panel, each located at a premises and generating alarm report data through a communications network to at least one alarm receiver located at a central station remote from the premises. A line card receives the alarm report data. An alarm receiver processor receives and processes regulated alarm report data in accordance with Underwriter Laboratories 1610 requirements. A line card is operable for receiving non-regulated alarm report data that is not regulated in accordance with Underwriter Laboratories 1610 requirements and establishing a bi-directional link for the non-regulated alarm report data between any central station automation system and the alarm panel at the premises until the bi-directional link is no longer required.
