Techniques for intruder detection
Methods, systems, and devices for intruder detection are described. A security and automation system may include a camera configured to monitor a zone of a premises. The security and automation system may detect a person in the zone, for example using the camera, a motion sensor, or another sensor. The security and automation system may determine that the person has remained in the zone for a threshold duration. The security and automation system may generate a notification (e.g. an audiovisual notification) based on determining that the person has remained in the zone for the duration. In some examples, the notification may include a verbal message, a flashing light, etc., to indicate to the person that video recording was initiated. The techniques described herein may inform an intruder that video is being recorded, which may discourage an intruder from an intended action (e.g., theft, property damage, etc.), among other benefits.
1. A method for intruder detection at a security and automation system associated with a premises, the method being performed by a computing device comprising at least one processor, the method comprising:
monitoring, by a camera of the security and automation system, an interior room of the premises within a field of view of the camera;
detecting motion in the room from a first source of motion based at least in part on the monitoring;
determining that the first source of motion indicates a person based at least in part on a characteristic of the motion of the first source of motion within the room, a second source of additional motion within the room, or a combination thereof;
determining a mode of operation for the security and automation system based on an occupancy of the premises, the mode set based on detection of an exit event corresponding to the premises;
determining the person has remained in the room for a threshold duration after the detecting, wherein the threshold duration is shorter in a first mode and the threshold duration is longer in a second mode;
initiating a video capture at the camera in response to determining that the person has remained in the room for the threshold duration; and
generating, via the security and automation system, an audiovisual notification based at least in part on determining the person has remained in the room for the threshold duration.
2. The method of claim 1 , wherein the audiovisual notification indicates the video capture has been initiated.
3. The method of claim 1 , further comprising:
determining a second notification based at least in part on determining the person has remained in the room for the threshold duration; and
transmitting the second notification to one or more devices associated with the security and automation system.
4. The method of claim 3 , further comprising:
receiving a response to the second notification; and
generating a third audiovisual notification based at least in part on receiving the response.
5. The method of claim 4 , wherein:
the response comprises at least one of a command, a text message, a confirmation message, a verbal message, or any combination thereof; and
the third audiovisual notification comprises a tone, a spoken announcement, an activation of a light, a flashing pattern of the light, the verbal message, or any combination thereof.
6. The method of claim 3 , wherein the one or more devices comprise at least one of a communication interface of the security and automation system, a remote device associated with an occupant of the premises, a device associated with a network operations center, a device associated with an emergency response provider, or any combination thereof.
7. The method of claim 1 , wherein determining that the first source of motion indicates the person comprises:
detecting, by a sensor, a motion associated with the person in the room based at least in part on the monitoring;
identifying one or more characteristics of the presence based at least in part on detecting the motion; and
determining that the first source of motion indicates the person is based at least in part on identifying the one or more characteristics.
8. The method of claim 7 , wherein the one or more characteristics comprise one or more facial features of the person, a profile associated with the person, a gait associated with the detected motion, a speed associated with the detected motion, a direction associated with the detected motion, or any combination thereof.
9. The method of claim 1 , wherein the camera is positioned on an exterior surface of a building on the premises.
10. The method of claim 9 , wherein the camera is located within a housing of a doorbell.
11. The method of claim 1 , wherein the audiovisual notification comprises a tone, a spoken announcement, an activation of a light, a flashing pattern of the light, or any combination thereof.
12. The method of claim 1 , wherein the security and automation system comprises a camera sensor, a motion sensor, a speaker, a control panel, a transceiver, a doorbell, a light, or any combination thereof.
13. An apparatus for intruder detection at a security and automation system associated with a premises, the apparatus comprising:
a processor;
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
monitor, by a camera of the security and automation system, an interior room of the premises within a field of view of the camera;
detect motion in the room from a first source of motion based at least in part on the monitoring;
determine that the first source of motion indicates a person based at least in part on a characteristic of the motion of the first source of motion within the room, a second source of additional motion within the room, or a combination thereof;
determine a mode of operation for the security and automation system based on an occupancy of the premises, the mode set based on detection of an exit event corresponding to the premises;
determine the person has remained in the room for a threshold duration after the detecting, wherein the threshold duration is shorter in a first mode and the threshold duration is longer in a second mode;
initiate a video capture at the camera in response to determining that the person has remained in the room for the threshold duration; and
generate an audiovisual notification based at least in part on determining the person has remained in the room for the threshold duration.
14. The apparatus of claim 13 , wherein the audiovisual notification indicates the video capture has been initiated.
15. The apparatus of claim 13 , wherein the instructions are further executable by the processor to cause the apparatus to:
determine a second notification based at least in part on determining the person has remained in the room for the threshold duration; and
transmit the second notification to one or more devices associated with the security and automation system.
16. The apparatus of claim 15 , wherein the instructions are further executable by the processor to cause the apparatus to:
receive a response to the second notification; and
generate a third audiovisual notification based at least in part on receiving the response.
17. The apparatus of claim 15 , wherein the one or more devices comprise at least one of a communication interface of the security and automation system, a remote device associated with an occupant of the premises, a device associated with a network operations center, a device associated with an emergency response provider, or any combination thereof.
18. A non-transitory computer-readable medium storing code, the code comprising instructions executable by a processor of a security and automation system to:
monitor, by a camera of the security and automation system, an interior room of a premises within a field of view of the camera;
detect motion in the room from a first source of motion based at least in part on the monitoring;
determine that the first source of motion indicates a person based at least in part on a characteristic of the motion of the first source of motion within the room, a second source of additional motion within the room, or a combination thereof;
determine a mode of operation for the security and automation system based on an occupancy of the premises, the mode set based on detection of an exit event corresponding to the premises;
determine the person has remained in the room for a threshold duration after the detecting, wherein the threshold duration is shorter in a first mode and the threshold duration is longer in a second mode;
initiate a video capture at the camera in response to determining that the person has remained in the room for the threshold duration; and
generate an audiovisual notification based at least in part on determining the person has remained in the room for the threshold duration.
