Description

[0001] CCTV camera apparatus capable of easy maintenance [

The present invention relates to a CCTV camera apparatus, and more particularly, to a CCTV camera apparatus capable of easily collecting and reinstalling a camera body for photographing the surroundings, thereby facilitating maintenance.

Recently, as public interest in safety has increased, many CCTV cameras have been installed on the roads, alleys, and so on, as well as on the main roads that many people are walking on. The CCTV camera transmits the photographed image data to the central control center through the network, and the manager monitors the scene captured by the CCTV camera through the control display installed in the central control center in real time. At this time, depending on the size of the management area or environmental factors, the number of CCTV cameras to be monitored is at least several tens to several hundreds. The prior art related thereto is disclosed in Patent Registration No. 10-1634622 under the name of integrated control system using location information and CCTV.

On the other hand, since the CCTV camera is installed in the outside environment of rain or snow, frequent breakdown occurs due to seasonal change or humidity change. In this case, the manager retrieves the failed CCTV camera and fixes and reinstalls it.

However, since the number of CCTV cameras monitored by the central control center is several tens to hundreds of units as described above, much effort has been required to collect and reinstall a large number of CCTV cameras for maintenance.

In addition, since CCTV cameras are installed at high positions of the poles or pillars and high positions of the buildings, workers were exposed to many risks in the process of collecting and reinstalling the failed CCTV cameras, resulting in frequent crashes.

In addition, it is inconvenient to use a maintenance vehicle or a ladder in order to collect and reinstall a CCTV camera. Nevertheless, in some places, it is difficult to maintain a CCTV camera because a maintenance vehicle can not enter due to a parked vehicle in advance.

In addition, the camera module of the CCTV camera must be exactly opposite to the specific crime prevention area, and when the CCTV camera is reinstalled, the opposite position of the camera module is shifted and inconveniences such as reinstallation have occurred.
