Sentry-Lite Mobile Surveillance Trailer


Mobile Security Camera Trailer - Live Video Surveillance - Where and When You Need It


Sentry-Lite is the low-cost alternative to other expensive surveillance trailers. The unit is self-contained and can be deployed almost anywhere in less than 10 minutes. The Sentry system puts live eyes on a problem location 24 hours a day without putting anyone in harm’s way. The system never sleeps, takes a break or calls in sick.

The Sentry-Lite offers a dependable video surveillance solution for any location needing live remote monitoring, crime deterrence or real-time police response. The uses are endless: parking lots, boat docks, ranch gates, farms, HOA’s, intersections, sports events, concerts, construction sites, parks, schools, universities, government buildings, police departments, and most off-grid locations. The Sentry-Lite is the perfect solution for locations where power and communications are not readily available.

Deterrence & Response


The presence of a police camera trailer on-site has an immediate deterrence effect on crime and other nuisance behaviors. The system offers three levels of monitoring and response. It can be deployed on-site and set to record all events to the onboard nvr without remote access or monitoring. The most popular option is the cellular data link service which allows you to remotely view cameras live, review recorded video, and receive programmed detection alerts directly to your smartphone. The most responsive option is our 24/7 video monitoring service. Our representatives respond to unwanted visitors in real-time, broadcasting warnings to leave and when needed, dispatch security services or the police.

Effective Coverage Area


The base unit is equipped with (3) Active Deterrence PTZ (pan, tilt, zoom) cameras providing an effective surveillance area of 100,000sq feet. The cameras are referred to as “active deterrence” because they are equipped with advanced AI, allowing the camera to detect a human as well as motorized and non-motorized vehicle profiles with 99% accuracy. Each profile can have unique custom automated responses independent from the other profiles. For example, when the camera specifically detects a human profile entering a selected area, the camera can automatically broadcast a message to the intruder and activate its warning lights, while launching the live video feed to your smartphone and notifying our central monitoring center. The cameras are also equipped with live two-way communication.



The Sentry offers the quickest deployment of any mobile surveillance trailer. • Pick the trailer location. • Level the unit with the drop-down levelers. • Deploy the mast. • Turn the power on. After a 2-minute start-up, the system will be recording and the live video will be accessible with smartphones and remote computers.



The Sentry-Lite system includes an on-site NVR (network video recorder) which records and stores 4K video. The NVR is connected to a Mobile Hotspot which requires a wireless data service. Live viewing, video playback, and remote motion alerts are all provided by this Hotspot which is equipped with a data card from a national cellular provider. We provide monthly data service through T-Mobile. If you prefer to use another cellular provider, their service will work with the hotspot but we will be limited in our ability to help you complete setup and configuration.

User Access


The Sentry-Lite video system can be accessed from anywhere you have cell service or access to the internet. Using your smartphone or PC, you can view live video from multiple cameras and perform multi-camera video playback on demand. Multiple users can be granted access to the system. Each user is given their own login credentials and can be limited to selected cameras and what features they can use.

Video Storage


The Sentry comes equipped to store 2 weeks of continuous 4K live video from all cameras.

Managing the System


The Sentry-Lite solar camera trailer is equipped with our advanced Cyber Secure surveillance system. The system's advanced AI allows each camera to be programmed for special detection events that trigger custom alerts and responses all in real-time! Be proactive and monitor the system live or don’t worry about a thing and wait for a custom alert to let you know that your attention is needed. You decide how you want to use the system and we’ll program it to do just that.

Live Monitoring & Dispatch


When your application needs a live response, our video monitoring service is the solution. For less than $1 per hour, our 24-hour monitoring service provides real-time response to events on site. The Sentry communicates alarm conditions instantly to our monitoring center. Our operators respond live with warning messages, and sirens.

Why we use Tilt-up No-sway Masts

There are two types of masts which the cameras are mounted, telescoping and tilt-up. The most common is the telescoping mast. They come in a variety of manual crank and powered versions. We prefer the tilt-up mast for several very important reasons. First the telescoping masts have a big design flaw. They sway, they sway in the wind a lot. Some even require support guide wires from the top of the mast to the trailer frame just to stabilize it. The real problem is when a PTZ camera is zoomed in to a target area and the mast sways half an inch, the zoomed in view ways 2 to 3 feet horizontally. This makes AI human detection less reliable, less effective and the video quality suffers. Our tilt-up mast has no such problems with the wind, our single piece no-sway mast puts the cameras at the 18 foot height as others, without all the wiggle. Tilt-up masts require less moving parts and deploys quickly and reliably with our hand crank design, simple and reliable.
