Europol Public Information Floor space requirements  Racks  Cameras   Page 14 of 35  Any new or replacement camera needs to be fully integrated in existing Europol management solution  (WinPak).  On each of the other site of the rows, in the warm aisles also 360 PTZ camera are located.  Within the cold aisle one 360 PTZ (Pan Tilt Zoom) camera is located.  Next to the fixed camera pointing to the double door, one or more fixed cameras are located in the Data  Centre to ensure that Europol ICT staff can follow any person entering and walking in the Data Centre.  From inside the SNL Data Centre, a ceiling mounted camera points at the double door so Europol ICT staff  can see who is outside the double door to access the SNL Data Centre. If one of the double doors is  opened, automatically an alarm is generated in Europol ICT operations team, the cameras in front and  back of the compromised rack automatically point to the rack and the zooming possibilities show the full  rack and the images of the camera are automatically seen on the screen by Europol ICT staff. Two more  fixed cameras are mounted to the ceiling to oversee the full SNL Data Centre.  Due to increasing size of some key components the racks will be deeper, likely 1200mm.  Each rack is to be labelled by the successful tenderer; the rack is to be labelled with SNL-<row>-<rack  number>. The racks in the 5 rows are therefore labelled as SNL-1-1 to SNL-1-5 up to SNL-10-1 and SNL-10- 5. The front of the rack is considered in the cold aisle.  The fifty (50) 19” racks 51RU height are lined up in 10 rows of 5 racks in a hot or cold aisle set up,  including adjustable perforated tiles. Each rack has on both side 2 perforated half doors that can be easily  removed. The door that closes the hot or cold aisle needs to close by itself after a number of seconds  after opening. In the cold aisles, opposite racks need to have a distance of at least 1400mm and in hot  aisles at least 1000mm.  A ramp needs to be provided in front of the double door to access the SNL Data Centre from the concrete  floor up to the raised floor. The ramp should be constructed that way that it cannot slide away. In case of  expansion it should be possible to move the ramp. The slope need to be able to seamlessly support a  trolley with euro pallet holding Data Centre goods moving in and out the SNL Data Centre.  The 2 fire protection walls need to be provided including a double door to enter to separate SNL Data  Centre and the surrounding area. The double door needs to have a width of at least 2 meters and height  of about 3 meter.  The SNL Data Centre needs to have a raised floor.
