Since 1999, The Tehran Metro has been making life more convenient, and more pleasant for the people of Tehran and for visitors to this ancient city. Consisting of five lines at a combined length of 152 kilometers, with two more lines currently under construction that will bring the total length to 430 kilometers, the Tehran Metro is also linked to Iran’s regional rail network and has become a crucial part of the great city of Tehran.

As the Metro Network Expands, Surveillance Needs Become More Demanding.
Tehran Metro's development of new lines involves a vast working area. In order to ensure the safety of this line's future commuters, as well as the safety of its current workers, Tehran Metro required a surveillance system to cover the tunnels, platforms, and workshop areas of this rapidly expanding network. The Tehran Metro Company's long-standing history of looking for the best technical solutions led it to seek the help of Pooya Fara Negar (PFN) in its search for the right system to meet this difficult challenge.
VIVOTEK – Clear and Wide Coverage, Built Tough to Perform anywhere.
PFN, with a long history of deploying high-tech cameras in difficult operating environments, turned immediately to VIVOTEK and its range of high-performance IP network cameras. The broad range, high resolution, flexible storage capability and impressive durability of VIVOTEK's surveillance systems ensured that Tehran Metro Company could continue work on developing its new line, secure in the knowledge that the working areas, tunnels and platforms could all be monitored on a secure and stable high-performance IP network system. With VIVOTEK's wide range of IP network cameras, advanced network video recorders and video management systems, the often-chaotic construction areas where able to be simply, easily, and thoroughly secured.
High Light, Low-Light or No-Light – No Problem For VIVOTEK's Smart IR and WDR Pro Equipped Cameras.
A total of 82 VIVOTEK IP network cameras were installed throughout the construction area of the Tehran Metro. The difficult lighting conditions of the tunnels and workshop areas called for extremely capable camera, and for this task VIVOTEK's IP8371E low light corridor view network bullet camera with Smart IR was perfectly suited. The IP8371E's 3D Noise Reduction technology empowers it to capture clear, polished video under low-light conditions, and also helps to reduce bandwidth from sensor noise. This camera is equipped with powerful 30 meter-range IR illuminators, and also features Smart IR technology which prevents overexposure and provides noise reduction to adjust the IR lighting intensity instantaneously based on the changes of light in the ambient environment.
For entrance areas, VIVOTEK's IP8335H was chosen for its excellence in providing high-detail, high-quality footage in both high and low-light conditions. The IP8335H WDR Pro feature enables the camera to provide video quality close to the capabilities of a human eye. To add to this, the IP8335H also features automated shutter control, or P-Iris. P-Iris controls the iris with extreme precision with a built-in stepper motor, maintaining the opening at an optimal level at all times, resulting in superior image clarity and depth of field as well as image quality – no matter what the lighting conditions. So the entranceways of the Tehran Metro construction areas, which were often effected by changes in ambient light, can now be reliably monitored.
VIVOTEK's Video Management Systems: Ready for Any Development.
Finally, the construction area of the Tehran Metro, though covering a vast area, is all able to be monitored from a single location thanks to the intelligence of VIVOTEK's VAST video management software. The features of VAST allow flexible monitoring of a large network of IP network cameras over a variety of locations by a small number of security staff, with new cameras able to be added at any time; meaning that as the Tehran Metro construction project grows or changes, the entire surveillance system can grow or adapt with ease. So now Tehran Metro can get on with task of expansion and providing the people of Tehran with ever more convenient services, confident that VIVOTEK is there to support them in this challenging project.
