The complexities once encountered in this case includes the unpleasant weather and high humidity of the region as it may cause the erosion of devices and thus shorten their lifespan; also, the high temperature and moisture may affect the smooth transmission of IP stream during deployment and installation. In order to solve the mentioned hassles despite that the climate is an unalterable factor, Dahua, Videotrend and the local system integrator attempted to approach it from a different perspective — the structure. The system adopts a ring networking structure with optical fibre adopted instead of a conventional star-topology one and to further guarantee an adequate bandwidth at 108Mbps for the cycling lane, the radio transmission system was configured at an access point of dual band 2.4/5.8GHz.
At the product front, Dahua 3- and 2-megapixel IR cameras (IPC-HFW3300P / IPC-HFW3200CP) and 2Mp 20x speed domes (SD6982A / 6523H-HN) cruised into the final after a series of testing. Equipped with lens of 3.3~12mm and 8~16mm, box cameras manage to take a wide range scenario under surveillance. What’s more, with the help of high efficient IR LEDs, cameras could also render a superb night vision effect; and as for the back-end devices, Dahua NVR, DH-SVR3016H, is applied as it can satisfy the storage of large volume footage as well as its RAID function can manage to enhance reliability and stability of the system.
“The previous problems have been well addressed by this solution, which, at the same time is quite flexible and convenient,” said Pasquale Totaro, the CEO of Videotrend. “It has been almost over two years since the project accomplished, and everything still goes well. The local officials are satisfied with this project as it not only helps to do with the citizen check, but also makes the whole surveillance system run smoothly.”
“We appreciate client’s trust and partners’ effort in this case, as we are refining network product portfolio, more versatile products will be brought out at different demands,” said Elmer Zhang, Sales Director for Europe at Dahua Technology. “Take this port case for example, the speed domes installed on the bridge is IP66 rated, which can withstand the severe environment; and its accurate PTZ function well helps with vehicle tracking. We are confident to provide solutions and products in various verticals as we have been actively involved in different projects and accumulated valuable experiences in recent years.”
