a second communicator that communicates with the wearable camera, and

a second recorder that records second image data of the capturing area captured by the vehicle-mounted camera in a second memory,

wherein the vehicle-mounted recorder instructs the second recorder to start the recording of the second image data when the recording start request is received, and the vehicle-mounted recorder generates a recording start instruction to start the recording of the first image data captured by the first imaging unit of the wearable camera and transmits the recording start instruction to the wearable camera simultaneously with instructing the second recorder to start recording of the second image data,

wherein the wearable camera starts recording of the first image data upon receiving the recording start instruction generated and transmitted by the vehicle-mounted recorder, and

wherein a recording start trigger correlated with the first image data recorded by the first recorder of the wearable camera is stored in the data storage of the wearable camera, the recording start trigger being an instruction from the vehicle mounted recorder or operation of the recording switch, the recording start trigger correlated with the first image data capable of indicating to a user of the first image data recorded by the first recorder of the wearable camera, a factor which caused the first recorder of the wearable camera to start recording of the first image data.

2. The wearable camera system according to claim 1 ,

wherein the vehicle-mounted recorder instructs the second recorder to stop the recording of the second image data when a recording stop request is received, and transmits a recording stop instruction to the wearable camera simultaneously with instructing the second recorder to stop recording the second image data, and

wherein the wearable camera stops recording of the first image data after receiving the recording stop instruction.

3. The wearable camera system according to claim 1 ,

wherein the recording start instruction includes a transmission time of the recording start instruction from the vehicle-mounted recorder to the wearable camera.

4. The wearable camera system according to claim 3 ,

wherein the wearable camera further includes

an operator, which in operation receives an attachment operation of attribute information related to the first image data, and

a first controller that causes identification information of the first image data, the attribute information and a transmission time of the recording start instruction corresponding to the recording of the first image data to be stored in the first memory by correlating the identification information, the attribute information and the transmission time with each other when the attachment operation is received, and

wherein the vehicle-mounted recorder further includes

a second controller that causes identification information of the second image data and a same time as a transmission time of the recording start instruction corresponding to the recording of the second image data to be stored in the second memory by correlating the identification information and the same time.

5. The wearable camera system according to claim 1 , further comprising: a notification lamp mounted on the vehicle that gives notification of an emergency state, and

wherein the vehicle-mounted recorder acquires the recording start request in response to turning on the notification lamp.

6. A recording control method in a wearable camera system that includes a wearable camera capable of being worn by a user, a vehicle-mounted recorder and a vehicle-mounted camera which are mounted on a vehicle in which the user rides and are communicably connected to each other, the method comprising:

performing communication between the wearable camera and the vehicle-mounted recorder;

capturing an image of a capturing area by the wearable camera;

capturing an image of the capturing area by the vehicle-mounted camera;

operating a recording switch of the wearable camera;

in response to operating the recording switch of the wearable camera, causing the wearable camera to transmit a recording start request to the vehicle-mounted recorder;

instructing that recording of second image data of the capturing area captured by the vehicle-mounted camera be started in response to receipt by the vehicle-mounted recorder of the recording start request from the wearable camera;

transmitting a recording start instruction to start recording of first image data of the capturing area captured by the wearable camera, from the vehicle-mounted recorder to the wearable camera, simultaneously with instructing the vehicle-mounted recorder to begin recording the second image data of the capturing area captured by the vehicle-mounted camera;

starting recording of the second image data in the vehicle-mounted recorder in response to receipt of the recording start request;

starting recording of the first image data of the capturing area captured by the wearable camera in the wearable camera upon receipt of the recording start instruction by the wearable camera; and

storing in the wearable camera a recording start trigger correlated with the first image data of the capturing area captured by the wearable camera, the recording start trigger being an instruction from the vehicle mounted recorder or operation of the recording switch, the recording start trigger correlated with the first image data capable of indicating to a user of the first image data captured by the wearable camera a factor which caused the wearable camera to start recording of the first image data.

7. The recording control method in a wearable camera system according to claim 6 , further comprising:

instructing the vehicle-mounted recorder to stop the recording of the second image data when a recording stop request is received; and

transmitting a recording stop instruction to the wearable camera simultaneously with instructing the vehicle-mounted recorder to stop recording the second image data, wherein the wearable camera stops recording of the first image data after receiving the recording stop instruction.

8. The recording control method in a wearable camera system according to claim 6 , wherein the recording start instruction includes a transmission time of the recording start instruction from the vehicle-mounted recorder to the wearable camera.

9. The recording control method in a wearable camera system according to claim 8 , further comprising:

receiving by an operator of the wearable camera an attachment operation of attribute information related to the first image data;

storing in the first memory identification information of the first image data, the attribute information and a transmission time of the recording start instruction corresponding to the recording of the first image data to be stored in the first memory by correlating the identification information, the attribute information and the transmission time with each other when the attachment operation is received; and

storing in the second memory identification information of the second image data and a same time as a transmission time of the recording start instruction corresponding to the recording of the second image data to be stored in the second memory by correlating the identification information and the same time.

10. The recording control method in a wearable camera system according to claim 6 , further comprising:

providing a notification of an emergency state via a notification lamp mounted on the vehicle, wherein the vehicle-mounted recorder acquires the recording start request in response to turning on the notification lamp.

11. The wearable camera system of claim 1 , wherein the recording start trigger includes information indicating that the second recorder started video recording of an incident attended by the user of the wearable camera.

12. The wearable camera system of claim 11 , wherein the user of the wearable camera is a police officer or a security guard.

13. The recording control method of claim 6 , wherein the recording start trigger includes information indicating that the second recorder started video recording of an incident attended by the user of the wearable camera.

14. The recording control method of claim 13 , wherein the user of the wearable camera is a police officer or a security guard.
