Claims (2)

  1. A dashcam that is installed in a vehicle, It has a security feature that takes pictures and records while parked. It has a continuous recording mode that performs parking recording by continuously taking and recording images, and when a predetermined event condition occurs, it creates a recording file for a predetermined time before and after the event and records it to the recording device. The aforementioned predetermined event conditions include a door open, which detects that a vehicle door has been opened. The aforementioned door opening is detected by detecting a change in sound pressure inside the vehicle using a microphone for door opening detection. The aforementioned microphone for detecting the door opening is separate from the recording microphone, and the drive recorder is characterized in that the microphone for detecting the door opening and the recording microphone are mounted in a single housing.
  2. The aforementioned predetermined event conditions include an impact that indicates the vehicle has been subjected to an impact of a certain magnitude or greater, The aforementioned impact is detected by an acceleration sensor, The aforementioned predetermined event conditions include a vehicle tilt exceeding a certain level, and a tilt indicating the detection of jacking up. The aforementioned inclination is detected by an inclination sensor. The drive recorder according to claim 1, characterized in that the tilt sensor is an acceleration sensor, but is a separate sensor from the acceleration sensor used to detect impact.

Description

This invention relates, for example, to sensors and electronic devices. For example, Patent Document 1 discloses a drive recorder that operates even when parked. This drive recorder, for example, in paragraph [0039], states that "...the camera is normally positioned to photograph the front of the vehicle, but when using this function, for example, the camera is positioned facing inward to photograph the interior of the vehicle. Furthermore, by providing an external power supply means such as a battery and supplying the necessary power to operate the drive recorder from this power supply means, the drive recorder can continue to operate and record the conditions inside the vehicle even when the vehicle's power is OFF, such as when parked. This allows, for example, monitoring the interior of the vehicle even if an intruder enters while parked." Paragraph [0069] then states that, for the above-mentioned function of operating while parked, "for example, in addition to an acceleration sensor, a motion sensor for detecting moving objects may be provided to detect impacts to the vehicle or drive recorder and record video and audio, as well as detect and record video and audio of people moving inside the vehicle."

The embodiments of the present invention will be described below with reference to the drawings. These drawings are used to illustrate the technical features that may be adopted in the present invention. The configuration and shape of the described apparatus are merely illustrative examples, and the present invention is not to be construed as being limited thereto. Various changes, modifications, and improvements may be made based on the knowledge of those skilled in the art, without departing from the scope of the present invention. As shown in Figures 1 to 6, the drive recorder 10 of this embodiment comprises a main unit 11 that performs various processes, a camera unit 12 attached to the main unit 11, and a bracket 13 for attaching the main unit 11 to a predetermined position on the vehicle 1. The predetermined position on the vehicle 1 is preferably, for example, the upper side of the vehicle's windshield 2 on the interior side, near the center. In addition to a drive recorder function that photographs and records predetermined areas such as the front of the vehicle 1 and the interior of the vehicle 1 during driving, the drive recorder 10 of this embodiment also includes a security function that photographs and records predetermined areas such as the front of the vehicle 1 and the interior of the vehicle 1 during parking, for example. The main unit 11 is equipped with various sensors and has an event recording mode that controls the shooting and recording operation based on the detection output of these sensors during the operation of either the drive recorder function or the security function, and a continuous recording mode that records continuously. To implement this security function, even when the vehicle is parked and the ignition switch is OFF, meaning it cannot receive power from the vehicle's battery, the drive recorder 10 should operate by receiving power from a separate power supply unit. Furthermore, having such a separate power supply unit is beneficial beca
