Tunnel Operators need the very best tools to avoid baseless claims and stay profitable
The N-Spex system of Entry, Exit and Tunnel cameras document the condition of every vehicle that enters and leaves your tunnel, as well as monitoring the wash process.

It’s easy for customers to blame your Car Wash for damage, but most of the time the damage is either pre-existing, (but not discovered until an after-wash inspection), or the damage occurred after the vehicle left your facility.
Without proof of when the damage was present, you can ultimately be held liable for almost any claim presented.
Busy Tunnels that have the N-Spex system have reported that the system has paid for itself in less than 6 months. In fact, one Operator says that 2 claims in the same month that were avoided with solid evidence from the N-Spex system, more than paid for the entire N-Spex equipment costs.
• An Express Tunnel in Georgia has experienced a spike in collisions in the tunnel during the past year. N-Spex Video has shown in most of the cases that the driver applied the brakes for some reason. Brake lights in the tunnel are seen time after time. The Operator reports that in a lot of those claims, the driver is plainly seen talking on their cell phone as they entered the tunnel. Most of the drivers simply weren’t aware that they applied the brakes, but viewing the evidence convinced them. • A Full Service Tunnel in California reports that for the first time they have evidence refuting claims that their equipment scratched or dented a customers’ vehicle. They knew that the damage was probably pre-existing, but without detailed vehicle condition documentation showing the dent as the car entered, or showing that the vehicle didn’t have damage when it left the tunnel, it was impossible to convince a customer that they were not to blame. The Operator says that after viewing the evidence, customers were no longer “100% sure that your wash damaged my car”.
The N-Spex Vehicle Condition Documentation System gives you the High Resolution tools you need to avoid most damage claims, and can save you thousands of dollars per year.
“Two or more N-Spex Cameras in the Tunnel as well (varies with length)”
Tunnel Operators have tried for years to place cameras down low enough to get good side views of vehicles, but quickly ran into problems. If they placed the cameras just inside the doorways, there was not enough natural light available and the pictures were always too dark. When they placed them outside the doors they were prone to vandalism since they were in easy reach.
High-Resolution, Pre-Assembled, Pre-Focused and Ready to Mount Cameras
N-Spex Cameras at the Tunnel entrance and exit are so small as to go unnoticed, yet are rugged stainless steel and completely vandal-proof. Sealed, gasketed housings are weatherproof and high-pressure washdown resistant (NEMA IP-66 rated). These High-Resolution cameras are made from rugged stainless steel and feature a ¼” thick lexan viewing window with adjustable camera angle depending on how far away from the entrance you wish to start seeing the vehicle.
These High-Resolution cameras are pre-adjusted and pre-focused to provide the perfect solution to the viewing angles and distances you need to adequately document the condition of vehicles entering and leaving your facility. This makes installation a snap! (Installers are available for most areas of the country)
Inside the tunnel, we use vandal-proof Bay Cameras that are even more water-resistant than the outside cameras. After all, they have to endure mist, overspray and constant high humidity.
N-Spex Tunnel Cams are completely water proof and resistant to condensation and fogging. In addition, our exclusive dome coating is applied to resist etching by common car wash chemicals such as high and low PH pre-soaks. The Tunnel Cams come complete with wall mount brackets and extra conduit bases included in case you need to run conduit to them instead of going through the wall at the mounting point.

Most Tunnels will use two Tunnel Cams, but more may be needed according to how long your tunnel is and how your equipment is laid out.
Since the purpose of the N-Spex System is to document the condition of every vehicle that enters and leaves your facility, Tunnel Operators use this evidence differently than they do for their surveillance cameras. Typically the N-Spex Video footage will not be reviewed unless there is a claim, whereas the surveillance cameras are used constantly to monitor processes, traffic and people on your entire property. For this reason, we recommend our dedicated N-Spex DVR be used with these cameras. This also allows the vehicle data to be stored longer since the archive space does not include footage from your regular surveillance cameras.
The N-Spex System comes in two standard configurations:
Single Tunnel N-Spex and Super N-Spex (for double tunnels or double Automatics)
Each of these systems can be infinitely customized to fit your unique situation, or we can design and build a system to fit any number of conveyors or bundled automatics (3, 4 or more at one site).
