Kamarajar Port Limited

Kamarajar Port, located on the Coromandel Coast about 24 km north of Chennai Port, Chennai, it is the 12th major port of India, and the first port in India which is a public company. The port was declared as a major port under the Indian Ports Act, 1908 in March 1999 and incorporated as Ennore Port Limited under the Companies Act, 1956 in October 1999. The Kamarajar Port is the only corporatized major port and is registered as a company. Today, the landlord port is the dominant port model in larger and medium sized ports.


KPL being a port is spread across a very large geographical area, had requirements to implement PTZ cameras and fixed cameras in three different locations which were few kilometers away from the central location. As a result, running FO cable between these locations will involve enormous cost and efforts. In addition, maintaining such long FO links will be tough. Hence, we proposed wireless links between the remote locations and the central location.

Understanding client requirements precisely, NTPL implemented connectivity employing Cambium (Motorola) point to point wireless technology as detailed below.

Outdoor PTZ Dome cameras were installed at various locations as per client requirement and integrated with the Administration control system. The cameras solution are all-in-one 24-hour outdoor surveillance cameras featuring 25x zoom and super dynamic technology. In addition, Fixed cameras were also installed at various location to be integrated with the existing control system and NVR.

NTPL provided Motorola Canopy Cambium 5200 AP 5.2 GHz Access Point Module (AP) which operates with a raw data rate of 10 Mbps and has a range of approximately ten miles (5.2 GHz SM with reflector). And SM was proposed as transmitter.

Point to Multi point architecture was employed. Admin Block was the central location which contains the AP, and the SM were placed one each at the three locations which are CISF location, Car parking Yard location and Scanian yard location. Distance between Admin block to CISF was 3 KM, Admin to Car parking yard was 4 KM, Admin block to Scanian yard was 3 KM. We placed a pair of Air grid in Admin block existing tower.

Point to Point architecture deployed as we implemented two numbers of air grid one in each location. At GCB in a tower and at GCB-NBW tower already had existing SM from client which was configured to directly communicate with our AP in admin block.

Our client finds it cost effective to have the Cambium wireless point to point solution. And is very happy with the ease of implementation and maintenance of their surveillance solution.

Considering the distances, wireless solution was proposed, since wired solution, required digging soil and lay fiber cables over long distances. Considering security challenges and cost effectiveness NTPL proposed wireless solution with cambium AP.

Cambium Networks’ Gigabit wireless solutions enable KPL to tailor connectivity to meet exact requirements and grow as needs evolve. Cambium Networks’ solutions enabled video surveillance at the edge of the network and are managed through an end-to-end wireless network manager.

A combination of above steps covered client’s end-to-end connectivity over long distances and also minimized total cost of Project.
