I · THE UNIT

One trailer. Total deterrence.

The CastleWatch unit is a self-sufficient, solar-powered security trailer that turns any open site into a watched perimeter in minutes — no infrastructure, no trenching, no site power. Every unit does four things: deter, monitor, alert, and record.

UNIT-M1 · SOLAR · OFF-GRID

Solar-Powered & Off-Grid

No wiring, no trenching, no site power. Deploys anywhere the sun hits and runs through the night on stored power.

High-Visibility Deterrence

Flashing lights, sirens, and signage announce a watched perimeter. Presence does the preventing.

Active Talk-Down & Sirens

Live audio warnings the instant motion is detected — intruders hear they are being watched and leave.

360° HD Surveillance & Recording

HD cameras with motion-activated, night-vision recording. Every angle, every incident, preserved as evidence.

Live Remote View & Alerts · Standard

Watch your site in real time from your phone or tablet with instant AI-powered alerts the moment motion is detected. Self-monitoring is standard.

24/7 Pro Monitoring · Optional Upgrade

Add our Rancho Cucamonga monitoring team to watch your unit around the clock, with verified dispatch and guard response.

II · SOLUTIONSCASTLEWATCH // SOCAL
II · SOLUTIONS

Built for the sites thieves target most.

More than deterring theft and vandalism — a visible CastleWatch presence protects your employees and customers, and keeps vagrants and loitering off your site. Wherever there's open perimeter, exposed inventory, or no grid power, a trailer deploys rapidly and starts deterring the moment it lands.

CONTRACTORS · JOBSITES

SELF-STORAGE · GATE-LEVEL

YARDS · LOADING DOCKS

Don't see your site?

Churches, schools, parks, equipment yards, vacant lots, and illegal-dumping hotspots — if it has an open perimeter and needs watching, we deploy there too.

III · LOCAL AUTHORITYCASTLEWATCH // SOCAL
III · THE LOCAL AUTHORITY

Surveillance, simplified.

Guards are expensive. Fixed cameras need trenching and power. CastleWatch gives your site a visible security presence without turning it into another headache — a self-sufficient, solar-powered deterrent you can watch from your phone, deployed by a locally owned Southern California team.

IV · FIELD REPORTS

Trusted on the ground.

Southern California builders, operators, and property managers who put CastleWatch on their perimeter — and what they saw change overnight.

"We had copper theft hitting our job site every other week. Since CastleWatch dropped a unit on the lot, it stopped cold. The flashing lights and talk-down sirens actually run people off before they get near the materials."
Marcus Delgado
Site Superintendent · Delgado Construction Co.
⊿ RIVERSIDE, CA
"Our warehouse yard was a magnet for after-hours loitering. The trailer deployed in an afternoon with zero trenching, and now my phone pings the second anything moves on the property. Best rental decision we've made this year."
Priya Nair
Operations Manager · Summit Industrial Logistics
⊿ ONTARIO, CA
"I manage three retail centers across the Inland Empire. CastleWatch gives us a visible security presence without the cost of round-the-clock guards. Locally owned, fast to deploy, and they actually answer the phone."
