Reservoir inspections cover a wide area, with scattered points and complex environments. Dams, spillways, outlet towers, and shorelines along the reservoir... inspection personnel walk dozens of kilometers a day, relying entirely on walkie-talkies for communication.
However, traditional walkie-talkies are limited by distance. Beyond a few kilometers, they can no longer "get through." Remote reservoir areas and signal blind spots are even more of a communication "island." A few days ago, a person in charge of a reservoir management office came to us, saying that when inspection personnel worked in dispersed locations, they could not get in touch, and dispatching relied entirely on shouting. They wanted to find a terminal that could solve the cross-regional communication problem. We recommended the Chierda NB586 public network walkie-talkie.
Nationwide interconnection, unlimited distance
The NB586 relies on the 5G all-network network. Wherever there is a carrier signal, calls can be made, without distance limitations. Inspection personnel dispersed across different dam sections and on both sides of the reservoir can all be online with a single call from the dispatch center. The dual-SIM switching design automatically selects the preferred network in areas with poor signal, ensuring communication does not drop.
Platform recording + GPS positioning, dispatching is visible
The NB586 supports platform recording, and all calls can be traced, making management more standardized. With optional GPS positioning, the command center can view the real-time location and movement tracks of inspection personnel through the dispatch console, making it clear at a glance whether inspection routes have been fully covered. Flexible switching among individual calls, group calls, and broadcast calls enables rapid response for both daily inspections and emergency dispatch.
Long battery life + Type-C fast charging, no power loss during all-day operations
A reservoir inspection trip takes most of the day. If the device runs out of power, it means "losing contact." The NB586 comes standard with a 1500mAh battery and, combined with intelligent power-saving technology, offers long-lasting endurance. The Type-C charging port is highly universal, allowing recharging at any time in the car, in the office, or with a power bank.
Clear sound quality, 1.77-inch color screen
The environment around a reservoir is noisy, with strong wind and loud water sounds. The NB586 adopts professional audio tuning technology, delivering clear sound quality so instructions can be heard clearly even amid background noise. The 1.77-inch high-definition color screen displays base station information, battery level, and other status details, and remains clear even under strong outdoor sunlight.
Founded in 1988, Chierda has been deeply engaged in the professional communications field for 38 years, and its products are widely used in scenarios such as water conservancy, electric power, and logistics.
For reservoir inspection communications, it is the one to fall back on. Bring the NB586, and let every inspection get a response.
