Imaging unit and installation device to attach to another device

An imaging apparatus comprising;

• rectangular parallelepiped outer case including:
• a rear side provided in an optical axis direction,
• opposing right and left sides provided in a width direction, and
• opposing upper and lower sides provided in a height direction between the right and left sides;
• a lens located at a front side opposing to the rear side and at substantially a middle of the width direction and the height direction;
• an image sensor positioned to receive a light through the lens accommodated in the rectangular parallelepiped outer case;
• a button, configured to switch a power mode of the imaging apparatus to a turn-on state, located at the upper side;
• a flattened battery, having opposing first and second larger surface in area accommodated in the rectangular parallelepiped outer case, located behind the image sensor, wherein the first surface is substantially perpendicular to the optical axis and faces toward the rear side and the flattened battery intersects and is centered on the optical axis at a location that is adjacent to a side of the image sensor that is furthest from the lens;
• a display, configured to display a condition of the battery and not configured to display a picture image generated by the image sensor, being at a location rearward of the button in the optical axis direction;
• a USB interface and a memory card interface are located at the right side;
• at least one microphone configured to record sound;
• and
• circuitry configured to transmit data to an external device via communication including Wi-Fi communication and short range wireless communication of which a communication range is shorter than a communication range of the Wi-Fi communication,
• wherein the imaging apparatus is configured to be controlled by the external device via the Wi-Fi communication, and
• the external case includes at least one opening perpendicular to the optical axis of the lens to permit sound to enter the external case and reach the at least one microphone.

An imaging apparatus not having display part to display an image data, comprising:

• an image sensor;
• an image generating circuit configured to generate the image data based on an output from the image sensor;
• a lens disposed at a front side thereof, and disposed at substantially a center position of the imaging apparatus when viewed from the front side;
• a display part to display an indication indicating a battery condition;
• a terminal configured to be connected with an external device interface;
• a memory slot configured to receive an external storage card;
• a cover configured to cover the terminal and the memory slot;
• a battery disposed at a rear side of the image sensor, the battery being arranged perpendicular to an optical axis of the lens to intersect and be centered on the optical axis at a location that is adjacent to a side of the image sensor that is furthest from the lens;
• at least one microphone configured to record sound;
• and
• circuitry configured to
• transmit the image data and sound data recorded by the at least one microphone to an external device via a first wireless communication, and
• communicate with the external device via a second wireless communication which is different from the first communication,
• wherein the imaging apparatus is configured to be controlled by the external device via the first wireless communication,
• the imaging apparatus having a rectangular parallelepiped shape, and
• a surface of the imaging apparatus includes at least one opening perpendicular to the optical axis of the lens to permit sound to enter the imaging apparatus and reach the at least one microphone.
