The solution includes network speed domes, NVRs, transmission devices, a video-wall system and control keyboard Dahua Technology successfully helps to secure Ventanilla in Lima, Peru, together with local distributor Best Security del Peru. Covering a total land area of 73.52 km², Ventanilla is the largest district of province Callao and accommodates over 500,000 population, which leads to a high population density and more pressure on city infrastructures and facilities. The same as some other rising cities around the world, Ventanilla is in face of problems such as traffic jams and crimes, so the municipal government determined to create a better and safer living environment for citizens by launching safe city project with an all-around surveillance deployment. However, the project was ticklish to proceed at beginning as Ventanilla is a mountainous seaside city, which means installation and cabling would be a big challenge. To better figure out what would be the most optimal solution to this case, Dahua dispatched a professional team to Peru in order to provide first-hand support in time. Taking both topography and budget into consideration, Dahua and Best Security del Perú came up with a wireless solution, by which, all the media data can be transmitted to the center via access points, avoiding installation complexity and save spending on labour and cable at the same time. The complete solution includes network speed domes, NVRs, transmission devices, video-wall system, a control keyboard, which are of the best C/P ratio and high stability as required by the government. Hundred units of Dahua IR speed domes are installed across the city, getting streets and corners covered; and its IR distance is up to 80 meters, ensuring a good visual effect even under unfavourable lighting conditions. Meanwhile, 128-channel super NVRs and 16-channel NVRs are used as storage devices in order to manage massive data volume. Take super NVR as an example, it is of 384Mbps incoming bandwidth capability, rendering a smooth HD real-time preview and recording; and the NVR supports RAID5, which further ensures data safety and system stability. The wireless video transmission system includes access points, feeders, PoE, antennas and power cables, allowing a 3.0km to 5.0km long-distance fast transmission with a wide angle, by which, the coverage is further expanded. In addition, there is a Dahua 3 x 3 46-inch video wall installed in control room, incorporated applied with a video-wall controller to have a better central management, which can better optimise the manpower and police operations. “Generally, Dahua products performs well and the system operates stably for the whole project”, said Christian E. Buleje Pun, Manager of Information and Telecommunication Technology at Municipal of Ventanilla. “We appreciate the reliable quality, smooth running, low costs and advanced service of Dahua. Surely, we will continue select Dahua as our future cooperative brand for security projects in the future. If Dahua can provide longer warranty, that will be perfect. ” continued. “It was always a pleasure to work with Dahua Technology,” said Manuel Nolazco N., Gerente Técnico Comercial at Best Security del Perú. “They’ve done a lot of safe city cases around the world, which is very helpful and supportive during the implantation, and we are looking forward to cooperate more on safe city projects with Dahua in Peru.”
