Vehicle security device
An in-vehicle security device mountable to a surface to the rear of a rear-view mirror of a vehicle, comprising: a first image capture device configured to receive images in a first direction relative to the security device; a second image capture device facing a second direction, the second direction different from the first direction; and a first object detection module configured to detect the presence of an object exterior to a vehicle in which the security device may be mounted; wherein the first image capture device and second image capture device are arranged to begin capturing images and/or video responsive to the first object detection module detecting the presence of an object exterior to a vehicle in which the security device may be mounted.
1. An in-vehicle security device mountable to a surface to a rear of a rear-view mirror of a vehicle, comprising:
a first image capture device configured to receive images in a first direction relative to the security device;
a second image capture device facing a second direction, the second direction different from the first direction; and
a first object detection module configured to detect the presence of an object exterior to a vehicle in which the security device may be mounted;
wherein the first image capture device and second image capture device are arranged to begin capturing images and/or video responsive to the first object detection module detecting the presence of an object exterior to a vehicle in which the security device may be mounted; and
wherein the second image capture device is arranged to comprise a field of view that extends beyond the rear view mirror into a cabin of the vehicle.
2. An in-vehicle security device according to claim 1 , further comprising a second object detection module to detect the presence of an object exterior to a vehicle in which the security device may be mounted.
3. An in-vehicle security device according to claim 2 , wherein the first object detection module and the second object detection module are arranged to have overlapping fields of view with the field of view of the first image capture device.
4. An in-vehicle security device according to claim 2 , wherein the first object detection module is oriented at a first angle with respect to the direction of the field of view of the first image module and the second object detection module is oriented at a second angle with respect to the direction of the field of view of the first image module, the second angle being different to the first angle.
5. An in-vehicle security device according to claim 4 wherein the first angle and second angle are equal and opposite.
6. An in-vehicle security device according to claim 2 , wherein the first object detection module and the second object detection module both each comprise:
at least one signal transmitter operative to emit an object ranging signal;
and at least two signal receivers for each at least one signal transmitter operative to receive a reflection of the emitted object ranging signal;
wherein the at least one signal transmitter and the at least two signal receivers for each at least one signal transmitter are disposed relative to each other to reduce reflection of the transmitted object ranging signal from a surface of a protective member proximal the at least one signal transmitter that the transmitted signal travels through.
7. An in-vehicle security device according to claim 5 , further comprising an external housing and wherein the signal transmitters are arranged so as to minimise occlusion of the signal by features of the housing.
8. An in-vehicle security device according to claim 7 , wherein the signal transmitters are arranged to be at a distance from the inner surface of the housing so as to minimise destructive interference of the signal by the housing.
9. An in-vehicle security device according to claim 8 , wherein the distance is 0.6 mm.
10. An in-vehicle security device according to claim 1 , wherein the security device is configured to be connected to a second device such that image data and motion data captured on the second device is transferrable to the first device.
11. An in-vehicle security device according to claim 1 , wherein the motion detection module is a RADAR module.
12. An in-vehicle security device according to claim 1 , further comprising an inertial measurement unit.
13. An in-vehicle security device according to claim 12 , wherein the security system is configured to be operative in either a high power state or a lower power state responsive to an indication of a security threat by the inertial measurement unit.
14. An in-vehicle security device according to claim 13 , further comprising a memory device and/or a data transfer unit;
and wherein the device stores measurement data from the first image capture device, second image capture device, and the object detection modules on the memory card and responsive to the indication of a security threat, transmitting the data to an external device.
15. An in-vehicle security device according to claim 1 , wherein the second image capture device of the first device is a wide-angle lens.
16. An in-vehicle security device according to claim 1 , configured to be pivotably mountable to a surface to the rear of a rear-view mirror of a vehicle.
17. A mount attachable to a surface to the rear of a rear-view mirror of a vehicle and configured to provide pivotable coupling of an in-vehicle security device according to claim 1 to the mount.
18. An assembly, comprising a mount according to claim 17 and an in-vehicle security device according to any preceding claim pivotably mounted to the mount.
19. A vehicle comprising a security device according to claim 1 .
20. A vehicle comprising an assembly according to claim 18 .
