A case study of a CCTV system for LAN airline, a Latin American airline, based in Lima, Peru. The company operates scheduled domestic and international services, controlling over 70 percent of the domestic market. Its main base and maintenance center are at Jorge Chávez International Airport.
The airline’s surveillance system covers its office and airplane maintenance centre. LAN wanted its centre covered to ensure 100pc operations. However, since it is inside Jorge Chávez, cables nor wireless antennas are allowed in case it may generate electronic jamming. The Chinese CCTV product company Dahua Technology suggested a hybrid solution — a combination of AP (access points) and wire transmission; and then to wirelessly transmit the camera data to inter-connected sub-centres, and then cable-transmit to the control room.
The “AP mode” wireless video transmission system includes access points, feeders, PoE, antennas and power cables, allowing a 3.0km to 5.0km distance transmission with a wide angle, by which the coverage is further expanded.
There are in total hundreds of network cameras and Dahua speed domes in use, some of the Eco-Savvy series, with versatile shapes such as domes and box cameras according to the surroundings. To take the Eco-Savvy camera series as an example, the dome is able to provide quality image with much lower power consumption — saving up to 50pc energy it is compared compared with similar products from other companies. Dahua adds that the 6C-series speed domes also require less output power, lowering the power output of the airport.
As for storage, some 15 16-channel PoE NVRs were fitted, each with 384Mbps incoming bandwidth, for HD real-time preview and recording; and its PoE function simplifies installation and reduces signal interference, according to the makers. The network recorders accommodate up to 16TB with 4 SATAs supported, for 24-7 storage.
Luis A. Gómez Cornejo, Supervisor of Electronic Security at LAN Perú, said: “Actually, we had many bidders and the final reason that drives us to cooperate with Dahua is their outstanding product quality and service. We can see their professionalism in video surveillance and plus their sincerity makes us moved during the communication. The implementation went great, they deployed the system within quite a short time and the products are in very good performance.”
William Zhou, Sales Director for Latin Americas at Dahua Technology, said: “In recent years, we are going into vertical rather than providing simple and individual products. And this project deepened our insight and practical experience towards airport projects.”
