The Sentry-Pro mobile solar cctv trailer 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-Pro solar power trailer is the perfect solution for locations where power and communications are not readily available.


The Sentry light trailer is not just a live surveillance solution, but also an incredibly effective project management tool. Using our mobile apps, users can log into the video feeds live and monitor the activity such as workers’ performance, deliveries, weather conditions, and safety procedures.


The on-demand (4) weeks of 4K video recordings can be searched, and selected events downloaded to smart phones or computers. Automated AI programmed alerts can instantly notify users of an event. After hours our live monitoring center takes over assuring live deterrence response and PD dispatch if intruders do not comply with the commands to exit the protected area.

Deterrence & Response


The presence of a Sentry-Pro 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 (2) Active Deterrence PTZ (pan, tilt, zoom) cameras and (2) CS-PTZ300 Long Range Zoom PTZ cameras providing an effective surveillance area of 196,000sq 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.

Camera Selection



Each Sentry-Pro can support up to 5 Cyber-Secure surveillance cameras. Each unit can be customized with several different camera options in any combination. The camera options include active deterrence, long-range infrared pan-tilt-zoom, license plate capture, 24-hour color, motorized zoom and wide-angle fixed view. Give us a call and we’ll be glad to customize a Sentry-Pro to fit your exact needs.

License Plate ID & Capture

License Plate Capture

Add an LPR (license plate capture) camera to your Sentry trailer. The Sentry surveillance systems are equipped with advanced AI (Artificial Intelligence) built into the software. It provides the ability to identify license plates and send alerts if a known or unknown plate is detected. The system automatically detects, captures, and compares plates against a whitelist, blacklist, or unknown and can perform custom responses for each of them. The system automatically creates a video and snapshot of each plate which can be searched in the database. Several variables must be considered to reliably capture plates. Follow these rules and you’ll reliably capture plates.



The Sentry security camera trailer 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-Pro 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-Pro 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 4 weeks of continuous 4K live video from all cameras. Total storage time can be expanded by adding more hard drive space. If you have a need for longer storage, give us a call and we’ll be glad to calculate the storage needed.

Managing the System


The Sentry-Pro 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. If needed, they dispatch the local police or private security services, providing a visual description of the suspects and their location. This service offers the highest level of deterrence and response in the security industry.

Why we use Tilt-up No-sway Masts

There are two types of masts which the cameras are mounted, telescoping and tilt-up. We prefer the tilt-up mast for several 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 sways 2 to 3 feet horizontally. This makes AI human detection less reliable and the system less effective. 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.

Certificate of Origin & VIN Registration

Certificate of Origin, VIN & State Registrations

Each trailer is issued a Certificate of Origin and a VIN (Vehicle Identification Number). These documents allow the trailer to be registered with all 50 states for legal transportation on public roads.

Surveillance Trailers

What is a Surveillance Trailer?

Why are these strange, purpose built, surveillance trailers popping up all over the country? Are they the only reliable and cost-effective solutions available for crime deterrence and response? How do they work? Are they Effective?

Sentry Surveillance Trailers - 10 Minute Setup

Find Level Location

The area should be a reasonably level area, approximately 10x12ft. It should have easy access for deployment. Gravel, dirt, pavement, and concrete are normal platforms. Avoid sand when possible, deploying on sand can be difficult and with the likely hood of the trailer settling into the sand, the trailer may have to be leveled periodically.

Surveillance Trailers need a level area

Position the Trailer True South

Position the trailer so the solar panels are facing true south. True south can be found using an iPhone and the compass app. For the compass to show true south, you will have to access the setup on the phone, select the compass tool and select the default mode as “true north”. Locate the direction of true south and maneuver the trailer so the solar panels are facing that direction. Positioning does not have to be perfect but should be close. The solar panels will not need angle adjustments, they are set at 40 degrees which is optimal for 80-90% of North America. Detach the trailer from the vehicle using the tongue wheel strut for support.

Position the trailers solar panels facing south

Deploy the Leveling Struts

The trailer is equipped with (4) leveling struts. If you are deploying on dirt or soft soil its best to give the strut base a platform to stand on such as a piece of construction wood or a rocks. The point is the trailers are heavy and they can sink into soft ground over time making the mast and cameras unlevel.

Level the trailer using all four struts. It is ok if one or both wheels leave the ground while leveling, but it is best to leave some weight on the wheels so there are six points of contact to the ground rather than just four.

Leveling the Trailer

Using the leveling bubbles located on the tongue of the trailer, adjust the struts so the trailer is level left-to-right and front-to-back. If the trailer is not level, then the mast is not level and the PTZ cameras may not operate properly.

Access to Keys

Key Lock Box

The keys to the camera storage box and controls are found in the combination key box mounted on the side of the camera storage box (located on the tongue of the trailer). The key box is a combination code lock. The code is provided in the trailer’s documents provided at the time of purchase.

Slide the cover protecting the key box combination tumblers down, set the four-digit code and push the small button on the left down which will release the door to the compartment. The keys for the camera storage box and controls are enclosed. Note: You can leave the keys in the camera storage box, lock it, and put only the camera storage key in the key lock box.

Mounting Cameras to the Mast

Release the No-sway Mast

Release the rubber security strap securing the mast to the trailer. It is found halfway up the mast on the right while facing the solar panels. The crank assembly is usually located inside the trailer at the base of the mast, but some models have it located on the outside and some are motorized. Attach the crank handle (same one used to operate the tongue wheel) to the spindle and turn the crank several turns until the mast has risen 2-3 feet. Position the mast so it is at a comfortable height to mount the camera assembly to the mast.

Remove the cameras from the storage box, use both hands; the unit is made of steel. Hold the camera assembly close to the mast and attach the weatherproof RJ45 fittings to the ports on the mast. Slide the assembly onto the mast and secure it with the cotterless hitch pin (you may have to wiggle and tap the pin to seat it in on the opposite side).

Mounting the Surveillance Cameras and Deploying

LPR Cameras (License Plate Recognition)

If the unit is to be equipped with an LPR camera, secure the camera to the mast with the star handle fasteners (found in the storage box) and connect the cameras cable to the weatherproof network port located on the side of the mast. The camera can be mounted on either side of the mast and the camera mount adjusts 180 degrees allowing for 360 degree aiming of the LPR camera.

License Plat Capture Camera Mounting

Mast Deployment

With the cameras secured to the mast, continue to deploy the mast by turning the crank handle clockwise until the mast is deployed. Crank the handle until the mast is vertical and seated securely against the rubber pad located at the base of the mast support. Apply approximately five pounds of pressure on the handle to leave sufficient tension to lock the mast in place. Once fully deployed, remove the handle crank and place back into the storage box. Check the leveling of the trailer and make any leveling adjustments if any are needed.

Deploying the Mast

Powering the System On

Powering On

There are two control switches, one powers up the entire system and the other controls the blue LED strobe lights. These switches are located in the storage box. Switch both to on and wait for the systems to power up. The cameras will run through a five-minute self-check and the entire system will be operational. By default, the system will automatically start recording all cameras.

Remotely Accessing the Cameras

Accessing the System

Using the Cyber-Secure app or client software, a user will have immediate access to the camera’s view and control for adjusting each camera’s default viewing position. The app is available as iPhone and Android apps. To locate the app search for Cyber Secure by Backstreet Surveillance. Download and install on device, then call our support center for access to the system. 1-800-431-3056 Option 3.

Locking the Leveling Struts

Locking the Leveling Struts

Install the locking straps around the leveling struts, they are steel cables secured with combination locks which operate on the same code as the key lock box. Secure the straps around all four struts and their handle so the handle cannot be turned.

Tongue Lock

Install the tongue lock and put the key in the key box or the storage box. Remove the tongue wheel/strut and take with you so it cannot be vandalized.

Securing the Trailer

Locking Up

Once you have confirmed the cameras are live on your phone app, lock the trailer up. Secure the access panel, put the crank handle back in the storage box, place the keys back in the key box.

Locking Up

Initial Setup

If this is the first deployment for the trailer, we recommend contacting our support department for help customizing the operation of the system for that deployment. Our support center will help downloading the mobile app and grant access to the trailer.

Blue Strobe Lights

The manual toggle switch located inside the storage box operates the flashing blue lights on the trailer. We recommend they be operational during deployment, even during the day. People equate the system to be operational if they see flashing blue lights (excellent deterrence). For transportation, the toggle switch must be turned off, so the lights are not flashing, and traffic laws are not violated.
