Description

Dome-shaped camera having memory rack}

The present invention relates to a dome type surveillance camera, and more particularly, to a dome type surveillance camera having a memory rack that can be inserted/removed in a sliding manner on one side of a rotating body in order to easily attach and detach a memory card.

Recently, the frequency of use of a surveillance camera that captures a specific place in real time for security purposes has been further increased. It is common for these surveillance cameras to support pan/tilt/zoom beyond the limit of monitoring a fixed point. In particular, dome type PTZ cameras are frequently used in terms of efficiency of installation space and design.

In general, a dome type PTZ camera has a structure in which a memory card for storing images or a reset switch is installed on a PCB and rotates together when pan/tilt motion is performed. This is because, if such a memory card is disposed on a fixed member, a cable for connection to a rotating PCB is twisted, and a pan/tilt movement is also hindered.

Due to this structure, when installing a dome-type PTZ camera, it is inconvenient to separate/attach a plurality of screws to fasten the dome cover again after opening the dome cover and inserting a memory card. In addition, when the dome cover is removed or when the dome cover is incompletely fastened to the installation site, moisture or dust may enter. In addition, when the dome cover is separated from the dome-type PTZ camera installed on the ceiling, it may be inconvenient to connect a safety wire to the dome cover to prevent the dome cover from accidentally falling and damaging or injuring people.
