When TenSeven came to StoneWyck looking for a mobile surveillance trailer capable of 24/7 remote site monitoring completely off-grid, in conditions where running power or pulling fiber simply isn't an option we knew this custom camera trailer build needed to do more than just hold cameras in the air. It needed to be a self-sustaining surveillance platform that delivers broadcast-quality video around the clock, actively deters intruders before they become a problem, and keeps recording whether the grid is up, down, or three counties away.

Here's a closer look at what we built, why we chose the components we chose, and how it all comes together on a solar-powered camera trailer that's ready to roll into action anywhere TenSeven needs it.

‍

Eyes on Every Angle: The Camera Package

‍

The camera package is the heart of any remote site surveillance system, and we spec'd this one specifically for the wide-area, all-conditions monitoring that off-grid sites demand.

‍

3× Uniview IPC94144SFW-X25-F40C Dual-Lens PTZ Cameras

‍

Each of these PTZ cameras is essentially two cameras in one a 4MP fixed 4mm panoramic lens paired with a 4MP PTZ channel featuring 25× optical zoom. That dual-channel PTZ camera setup is a game changer for remote monitoring. The fixed lens delivers wide situational awareness across the whole scene, while the PTZ channel independently locks onto a person, vehicle, or anything else of interest and tracks it at detection ranges out past 2,475 meters (over 8,000 feet) at full zoom.

‍

Uniview's Lighthunter technology keeps these cameras delivering clean, low-noise color images well after dusk, and the combination of IR illumination out to 100 meters and warm-light fill makes them effective in any lighting condition. Smart intrusion analytics cross-line detection, area enter/leave, and human/vehicle classification filter out wind-blown debris and tree branches so operators only see what matters. With three of these PTZs positioned around the trailer, there are no blind spots.

‍

1× Uniview IPC86CEB-AF18KC-I0 12MP Fisheye Camera

‍

Mounted to provide a true 360° overhead view, this 12MP panoramic fisheye captures the entire area around the trailer in a single frame at 4000×3000 resolution. It's our "see everything at once" insurance invaluable for forensic review, situational context, and making sure nothing slips between PTZ patrol patterns.

‍

1× Uniview IPS302030-S IP Horn Speaker (Active Deterrence)

‍

This is where remote monitoring becomes active deterrence instead of just passive recording. The IPS302030-S is a 30W, 130dB IP-networked horn speaker  as loud as an emergency siren and engineered to carry across an open site. When the system's analytics detect an intrusion, operators issue a live two-way voice challenge directly through the speaker, or trigger pre-recorded warnings. The pattern shows up time and again: a real human voice on a remote site sends would-be trespassers running long before law enforcement could arrive.

‍

Reach: The 30-Foot Manual Crank Winch Boom

‍

A camera is only as good as its vantage point. The entire camera package mounts to a 30-foot boom raised by a manual crank winch  simple, mechanical, and reliable. No hydraulics to leak, no compressors to fail, no electronics in the lift system to draw down the battery bank or break down in the field. Just a crank, a cable, and a boom that goes up when you need it and comes down when it's time to move.

That elevation does two big things for site security: it dramatically extends the effective range of those 25× PTZ lenses (a clear line of sight is worth more than any zoom factor), and it puts the cameras well out of easy reach for tampering. When it's time to relocate, the boom comes down and the trailer is road-ready in minutes.

Built to Record Without Compromise: The Custom NVR

‍

A first-of-its-kind deployment. This build marks the first partnership between StoneWyck and Uniview to deploy their hardened NVR platform inside a mobile camera trailer. Off-the-shelf NVRs weren't going to cut it for what TenSeven needed and standard rack-mount enterprise NVRs aren't built for the vibration, temperature swings, and power realities of a mobile platform. Working directly with Uniview, we engineered a deployment that brings enterprise-grade recording capability into a hardened, trailer-mounted form factor.

The result: 180 days of continuous recording on-trailer...

‍

Off-Grid Power: 24/7 Solar with Lithium Backup

‍

Here's where a lot of "solar surveillance trailers" fall apart. Cameras, PTZs, an NVR, a cellular modem, and an IP speaker draw real power  and the system has to run 24/7, including through stretches of bad weather. We oversized the off-grid power system intentionally:

• 2× 400W solar panels (800W total) feed the trailer during daylight hours
• 2× 100Ah LiFePO4 lithium batteries (200Ah total) provide deep, stable storage with the cycle life and temperature tolerance that lead-acid simply can't match
• 1× Victron Energy SmartSolar MPPT Charge Controller manages the whole system intelligently, maximizing solar harvest and protecting the battery bank

The Victron SmartSolar is the brain of the power system  Bluetooth-enabled, app-monitored, and trusted across the marine, RV, and off-grid industries for a reason. Our team monitors battery state, solar yield, and load draw remotely, which means we know about a power issue before TenSeven's operators ever do.

‍

The Whole Greater Than Its Parts

‍

Anyone can bolt cameras to a trailer. What sets a StoneWyck custom camera trailer apart is the integration: the camera analytics talk to the speaker, the speaker talks to the operator, the operator talks to the offsite recording stack, and the power system underneath it all has enough margin to keep running when the weather doesn't cooperate.

‍

This trailer was built for TenSeven, but the philosophy behind it is something we bring to every build whether it's for construction site security, remote utility monitoring, critical infrastructure surveillance, or any application that demands eyes on the ground where the grid can't reach.

Design for the worst day, not the best one.

Frequently Asked Questions

How long can a solar camera trailer run without sunlight? Our builds are sized for multi-day autonomy. With 200Ah of LiFePO4 storage and an efficiently configured camera load, the TenSeven trailer can operate for several days of fully overcast weather before solar recharge becomes critical.

‍

How is footage accessed from a remote camera trailer? The custom NVR supports both local storage (180 days on this build) and parallel offsite cloud recording, so authorized users can review live and recorded footage from anywhere via secure remote access.

‍

Can a StoneWyck camera trailer be customized for my specific application? Absolutely. Every trailer we build is spec'd for the customer's exact use case boom height, camera selection, recording duration, power budget, and active deterrence features are all tailored to the deployment.

‍

What kinds of sites benefit most from a mobile surveillance trailer? Construction sites, laydown yards, solar farms, utility substations, remote infrastructure, agricultural operations, event venues, and any property where running permanent power and network isn't practical.

‍

Are these trailers NDAA compliant? Yes the Uniview camera and NVR equipment used in this build is NDAA compliant, making it suitable for federal, state, and municipal projects.
