CCTV monitoring in automotive wholesale center



GAZELO deals with import and distribution of spare parts for cars. In Poland, it is the sole representative of several manufacturers of electric fuel pumps and lambda sensors from Korea, Taiwan, and China.

To increase security and improve the organization of work in the new wholesale store, the investor decided to install CCTV monitoring. In the construction process the contractor made cabling to all planned outdoor camera points, using gel-filled cat 5e UTP cable, prepared for CCTV cameras placed in housings equipped with video transformers with BNC sockets - TR-1Q. Video signals from four cameras are received by video transformer TR-4P placed in the building and providing its output signals to the DVR. If needed in the future, the installation allows to transmit audio, e.g. for transmitting some orders. Indoor CCTV cabling has been based on CCTV YAR cable with two power wires.

The employed outdoor day/night SUNELL cameras have on board 1/3" SONY EX-View CCDs. Thanks to high parameters, the cameras can work even in extreme lighting conditions (e.g. they can be used for monitoring of roads). Some places, very dark at night, required to use compact cameras with IR illuminators. Outdoor color cameras (with 4-9 mm varifocal lens and IR illuminator)">VF-515 IR/B, with SONY Super HAD sensors, 550 TVL resolution, equipped with 4-9 mm varifocal lenses and IR illuminators seemed to be the best choice. They were easy to mount and adjust, providing quality images with increased resolution. The inside parts of the building and the rooms are monitored with the vandal proof cameras VC-412. This model of universal (ceiling / wall) color vandal-proof camera is equipped with built-in 3.6 mm lens and IR illuminator.

Images from the set of cameras are recorded by 16-channel DVR - CPD-507 and 4-channel DVR - CPD-560. Some selected images are also available via RF system (due to use of TERRA modulators MT27P) and can be viewed on TV sets located in administrative part of the building.

There are plans for future development of the system. The key cameras will be connected to ULTIMAX DVR that allows live monitoring, preview of archives, and configuration of the system via LAN or the Internet. H.264/AVC compression is 50% more efficient compared with the previous kind of MPEG-4 algorithms, saving disc space and available bandwidth of IP networks.
