Security system coupled to a door lock system

Abstract

A security system is coupled to a door lock system. A sensor is at a dwelling. The sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. An engine, an energy source and a memory are coupled together. The engine is coupled to the sensor. The memory provides information relating to open or closed status of a door to a dwelling occupant or a third party designated by the dwelling occupant. At least one motion detection device is provided to detect a person at or near a door or window at the dwelling. A security system includes a video apparatus that captures video and coupled to the motion detection device to take a video of an image of the person or an outline of the person, wherein the video is configured to begin before motion detection begins.

What is claimed: 
     
         1 . A security system coupled to a door lock system, comprising: a sensor at a dwelling, the sensor being coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door; an engine, an energy source and a memory coupled together, the engine being coupled to the sensor, an energy source, the memory providing information relating to open or closed status of a door to a dwelling occupant or a third party designated by the dwelling occupant; at least one motion detection device to detect a person at or near a door or window at the dwelling; and a security system that includes a video apparatus that captures video and coupled to the motion detection device to take a video of an image of the person or an outline of the person, wherein the video is configured to begin before motion detection begins. 
     
     
         2 . The system of  claim 1 , wherein the video apparatus records before the motion detection device detects. 
     
     
         3 . The system of  claim 1 , further comprising: a buffer to provide a buffering of an selected video. 
     
     
         4 . The system of  claim 3 , wherein the video apparatus is a camera. 
     
     
         5 . The system of  claim 4 , wherein the camera is a doorbell camera. 
     
     
         6 . The system of  claim 3 , wherein the buffer for a selected amount of time. 
     
     
         7 . The system of  claim 6 , wherein when motion is detected at a time T 0  a last buffer is marked for saving. 
     
     
         8 . The system of  claim 7 , wherein new-upcoming videos are recorded until there is a complete motion. 
     
     
         9 . The system of  claim 7 , wherein a video file is appended that includes the pre-T 0  buffer time of x seconds to create a video file which shows action starting at time To- x.    
     
     
         10 . The system of  claim 9 , wherein a buffer size is selected and in response a determination is made when to start a recording of video. 
     
     
         11 . The system of  claim 10  wherein motion is triggered by a PIR sensor. 
     
     
         12 . The system of  claim 11 , wherein once motion is triggered the security system analyses an x-second video buffer to pixel changes 
     
     
         13 . The system of  claim 12 , wherein the analyses provides that a beginning of the video is aligned with a first pixel change. 
     
     
         14 . The system of  claim 9 , wherein a motion speed is evaluated to provide that a slower an event, the longer the buffer time x is. 
     
     
         15 . The system of  claim 1 , wherein the security system includes at least one motion detection device.
