Protect materials, heavy equipment, and copper from jobsite theft and vandalism — even before power is on site.

Locally headquartered. Regionally unrivaled. CastleWatch deploys mobile solar security trailers across Southern California — high-visibility deterrence with flashing blue lights, talk-down sirens, and real-time alerts to your phone. No wiring. No theft.
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.
No wiring, no trenching, no site power. Deploys anywhere the sun hits and runs through the night on stored power.
Flashing lights, sirens, and signage announce a watched perimeter. Presence does the preventing.
Live audio warnings the instant motion is detected — intruders hear they are being watched and leave.
HD cameras with motion-activated, night-vision recording. Every angle, every incident, preserved as evidence.
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.
Add our Rancho Cucamonga monitoring team to watch your unit around the clock, with verified dispatch and guard response.
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.

Protect materials, heavy equipment, and copper from jobsite theft and vandalism — even before power is on site.

Deter loitering, break-ins, and after-hours vandalism across parking lots and storefronts without permanent installs.

Guard rows of high-value vehicle inventory around the clock with visible, audible deterrence and live monitoring.

Gate-level deterrence and talk-down that intercepts breaches before a unit is ever opened.

Secure equipment, materials, and loading docks across large yards and industrial perimeters.
Churches, schools, parks, equipment yards, vacant lots, and illegal-dumping hotspots — if it has an open perimeter and needs watching, we deploy there too.
Request a Site AssessmentSouthern 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."
"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."
"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."
One trailer, one transparent monthly package. No setup fees, no auto-renewal traps — cancel with 15 days' notice. One trailer often costs significantly less than standard guard coverage.
Self-monitoring with remote live view and real-time alerts is standard. Add 24/7 live monitoring and guard response only if your site needs it.
Not a sales call. A regional deployment specialist walks your site, maps its perimeter, and recommends trailer placement and coverage — no obligation, no national call-center handoff.
