An early-warning system for remote villages that have no one else watching over them. Three small solar-powered boxes on poles spot danger on the road in, sound an alarm the whole village can hear, and remember who came. They run on sunlight, and the alarm works even with no internet or phone signal.
The riders are quiet. One of them is carrying a rifle slung across his back. They have buried family members three times in the last two years — not in this village, but in others nearby. They know what is about to happen. No one inside the village does.
But this village has a Capture Node on a bamboo pole at the edge of the approach road — a solar-powered camera the size of a deck of cards, with a tiny $15 computer inside that can recognize what it sees. It does not stream video. It does not need to. It sees the riders, recognizes five people, three motorcycles, and a weapon, takes a few small snapshots, and sends them over its own long-range radio link to a reviewer in another country.
The reviewer takes nine seconds to confirm and presses a button.
Four kilometers away, mounted on a higher pole near the village square, the Alarm Node wakes up. A 30-watt horn speaker, audible to 400 meters, sounds the pattern the village has rehearsed. People rise in the dark. They do not pack. They do not look out the door. They take the route they have walked at noon a hundred times — down the wash, across the riverbed, to the shelter cut into the bank.
By the time the attackers reach the first hut it is empty. There is nothing to take and no one to find.
Meanwhile, in a third sealed box on a third pole, the Tower Node has been quietly listening for mobile phones the entire time. Every phone gives off a hidden ID number, even when no one is using it — a digital fingerprint. The Tower Node has recorded the fingerprints of four phones moving with the riders, along with their direction of travel. The numbers themselves mean nothing tonight. They are saved.
Six weeks later, forty kilometers away, near a different village, two of those fingerprints reappear on a different Tower Node. The alarm sounds automatically. No reviewer is consulted. No button is pressed. The riders have not yet stepped off their motorcycles.
Each village receives three sealed, solar-powered boxes, called nodes. Each one goes on a pole cut locally, and each one keeps working on its own. They talk to each other over their own private radio network, so they do not need cell towers, the internet, or a power line. A few nearby villages share one mobile-data connection to send photos to reviewers and routine status checks. The alarm never has to wait for that connection.
The villages that need this most are the villages where nothing else works. WatchTower does not need a power line or an internet cable. It runs on the sun, keeps going through cloudy days, stays sealed against rain and dust, and hangs on a bamboo pole cut from the bush a hundred meters away.
WatchTower comes in three builds. They do the same job. The bigger builds are faster, reach farther, and run longer without sun — but they cost much more. For the same money, the lean build protects roughly twenty times as many villages as the industrial one. For almost every village, lean is the right choice.
| Tier 1 · Lean | Tier 2 · Standard | Tier 3 · Industrial | |
|---|---|---|---|
| Cost per village | $500 | $1,850 | $9,920 |
| How fast it spots a threat | A few checks per second | About ten times faster | Near-instant, like live video |
| Phone detection | Older phone networks | Older + 4G networks | Older + 4G, with more precise timing |
| How the boxes talk | Long-range radio | Long-range radio + faster wireless | Professional-grade wireless + radio |
| Connection to the outside | A mobile phone used as a hotspot | Its own mobile-data modem | Satellite internet |
| Alarm reach | ~400 m | ~600 m | ~800 m+ |
| Runs with no sun for | ~36 hours | ~60 hours | 72+ hours |
| Best for | Pilots, maximum reach | Permanent setups, mid-size villages | High-threat & conflict zones |
WatchTower is in pilot deployment. We are looking for funding partners, technical collaborators, and ministry contacts in the regions where this is needed most. The math is straightforward: every village funded is a village that wakes up before the riders arrive.
