San Diego PD keeps US Open attendees safe with real-time drone video

The 121st US Open golf tournament, held in Torrey Pines, San Diego, drew unpredictable flows of thousands of people, causing heavy congestion on cellular networks. Tasked with keeping the crowd safe, the SDPD knew it was critical to maintain a high-quality signal to send and receive tactical video feeds to improve their situational awareness and response times.

The Dejero EnGo worked flawlessly, even during the busiest times of the event. We used the system for five days straight, for approximately 15 hours of flight time. It was extremely easy to use for sending and receiving the live transmission.

The Challenges

Cellular network congestion can limit bandwidth and reduce situational awareness

Transmitting high-definition, real-time drone video from anywhere across the 192-acre golf course.

Overcoming the line-of-sight constraint between drone pilot and receiving antenna of alternative solutions.

Establishing reliable, wireless broadband for the Joint Operations Center in the field so that officers would be able to monitor all incoming video feeds and access mission-critical public safety applications.

Overcoming the anticipated cellular network congestion from large crowds using the networks in a concentrated area.

Simplifying the setup and interoperability of onsite equipment.

At this year’s US Open, the SDPD’s drone division wanted to be able to fly absolutely anywhere along the golf course without worrying about positioning to achieve reliable connectivity.

The Solution

Combining multiple cellular networks into a single, ultra-reliable service to deliver high-definition, real-time drone video to commanders

Local network engineering contractor AggreGateway looked to Dejero’s easy-to-use solutions to provide San Diego PD police officers and incident commanders with the uninterrupted connectivity they needed. With the ability to monitor live video and access mission-critical apps from its Joint Operations Center (JOC) command post and SDPD headquarters in real-time, they were able to ensure the safety and security of the players, spectators, and PGA staff.

The Result

Real-time drone footage enables faster, smarter, and safer decision-making

Dejero mission-critical connectivity solution eliminated the line-of-sight constraints to provide continuous, uninterrupted drone video transmission enabling the SDPD officers to monitor and react to events in real-time.



Drone pilots no longer need to be in line-of-sight to a receiving antenna in order to send real-time video to command.



Continuous, uninterrupted, low latency video transmission enables the officers to monitor and react to events in real-time.



Dejero solutions come pre-configured — no extra training required so officers are up and running with the press of a button.
