Dual lens camera unit
First Claim
1. A camera unit comprising:
- a first lens assembly having a first optical axis;
a second lens assembly having a second optical axis;
a unitary, tubular lens housing containing both the first lens assembly and the second lens assembly,wherein the second lens assembly is rotatably mounted inside the lens housing such that the second optical axis is configured to allow manual rotation about only a single axis of rotation relative to the first optical axis,wherein the single axis of rotation is perpendicular to the first optical axis and perpendicular to the second optical axis,a mounting clip permanently secured to the lens housing and configured to selectively secure the lens housing to the body of a law-enforcement officer;
a battery unit;
a first storage memory;
a second storage memory;
controller circuitry operable to;
receive video data from the first lens assembly and the second lens assembly and store the video data and a timestamp for synchronizing the video data in the first storage memory; and
a battery housing containing the battery unit and attached via a cable to the lens housing.

12. A method of controlling the operation of a camera unit comprising the steps of:
-
simultaneously storing imagery from a first lens assembly and a second lens assembly to a first storage memory, wherein the second lens assembly is rotatably mounted inside a unitary, tubular lens housing such that the second optical axis is configured to allow manual rotation about only a single axis of rotation relative to the first optical axis, wherein the single axis of rotation is perpendicular to the first optical axis and perpendicular to the second optical axis, receiving a trigger signal in response to a triggering event; transferring the imagery from the first lens assembly and the second lens assembly from the first storage memory to a second storage memory; storing a timestamp for synchronizing the imagery in the second storage memory; and storing, in response to the trigger signal, said imagery from the first lens assembly and the second lens assembly in the second storage memory. - View Dependent Claims (13, 14, 15, 16)

17. A dual-lens camera apparatus, comprising:
-
a unitary, tubular lens housing including a plurality of non-paraxial lens assemblies, wherein a first lens assembly and a second lens assembly of the plurality of non-paraxial lens assemblies have non-overlapping fields of view, wherein the second lens assembly is rotatably mounted inside the lens housing such that the second optical axis is configured to allow manual rotation about only a single axis of rotation relative to the first optical axis, wherein the single axis of rotation is perpendicular to the first optical axis and perpendicular to the second optical axis; a mounting clip permanently secured to the lens housing and configured to selectively secure to the body of a law-enforcement officer; a battery housing connected by a cable to the lens housing and providing power thereto; a volatile memory; and a non-volatile memory, wherein the non-volatile memory stores video data simultaneously recorded by the first lens assembly and the second lens assembly and a timestamp for synchronizing the video data wherein the video data simultaneously recorded by the first lens assembly and the second lens assembly is transferred to and stored in the non-volatile memory upon a triggering signal related to a triggering event. - View Dependent Claims (18, 19, 20, 21)
