| 20150063643 | AUTOMATED, REMOTELY-VERIFIED ALARM SYSTEM WITH INTRUSION AND VIDEO SURVEILLANCE AND DIGITIAL VIDEO RECORDING - An automated self-monitored alarm verification solution including at least a premises portion, a server portion, and an end user device portion. Alarm verification includes capturing by an image capture device at least one image in response to a detection event, and transmitting a first data signal including the image to a local signal processing device. The signal processing device transmits a second signal including at least a portion of the image to a remote hosted server according to at least a first set of predetermined parameters. After receiving the second signal, the server transmits a third signal including at least a portion of the image from the hosted server to a user device. Using the user device, a user views the image and indicates a validity, status of the alarm based at least in part on the content of the image. Based at least upon either the validation status indicated by the user, or upon a failure to receive a message including a validation status from the user within a predetermined duration of time, the server portion may send an alarm signal to an emergency response service. | 2015-03-05 |
| 20150063644 | Image Capture and Identification System and Process - A digital image of the object is captured and the object is recognized from plurality of objects in a database. An information address corresponding to the object is then used to access information and initiate communication pertinent to the object. | 2015-03-05 |
| 20150063645 | Image Capture and Identification System and Process - A digital image of the object is captured and the object is recognized from plurality of objects in a database. An information address corresponding to the object is then used to access information and initiate communication pertinent to the object. | 2015-03-05 |
