A signal jammer cuts off the car's locks and its GPS at the same time, without forcing anything. CarDefense makes the attack visible and guides your team to whoever is carrying it out.
Includes
Illustrative video: a man holding a jammer tries to open a parked car and runs off when he sees the guard coming, with a spectrum monitor on top: the signals of the security systems, a jamming attack that covers them, and Tank's detection.
The problem
The locks, the alarm and the GPS are still installed, but they are cut off. Malls, strip centers, casinos, gas stations and parking lots gather hundreds of vehicles and, with them, the incentive.
The solution
Sensors that see the attack, a handheld detector that closes the search, Mission Control to manage every alert and Academy so your team knows what to do. Tank installs it, calibrates it and maintains it.
What is silence today becomes an alert with a place and a time.
The alert takes the right guard to the right place, and the search is closed on the ground.
Every event records who dispatched, who closed and who validated.
By venue, not by vehicle
An alarm or a GPS tracker only protects the car it is installed in, and it transmits over the same signal the jammer shuts down. A Tank sensor watches the entire venue: it covers every car that comes in, with nothing installed on it, and it sees the attack instead of going blind.
Coverage: up to 53 hectares with one sensor, a radius of 410 m.
Illustration · does not show the system's geometry or how it works
Comparison of two identical parking lots during the same attack. With one device per vehicle, only 2 of 12 cars are covered and, when someone switches on a jammer, those devices lose signal and no one finds out. With a Tank sensor, all 12 cars are covered, the sensor detects the attack in the zone and the security team heads there.
How it's used
01At a venue
The fixed sensors watch the venue and tell you in which zone the attack is happening. The guard with the handheld detector closes the last meters. That is how a mall, a casino or a gas station is protected.
Includes
02On patrol
A patrol carries the handheld detector and covers any area it passes through, such as open parking lots, streets or roads, without installing anything. When there is an attack nearby, the guard finds it on the ground.
Includes
The technology
Sees the attack
It watches the venue 24/7. When someone turns on a jammer, it alerts your team and tells it in which zone it is happening. One covers the venue; several add certainty.
Closes the search
CarDefense Mobile goes in the guard's hand and works like a radar. At a venue, it takes the guard from the zone flagged by the alert to whoever is carrying out the attack; on patrol, it covers the area being traveled.
Alert tablet
Receives the alert at the venue, where it is managed from.
Integration
With your CAD and the venue's cameras: Tank adapts to what you already have.
Where it works
Illustrative images with the actual equipment
Tactics · Time to target
The more precise the configuration, the less your guard has to search and the sooner they arrive. If your team reacts quickly, a more basic configuration may be enough for your time to target; if they need support, Sector or Hyperlocation bring them closer.
The macro-zone
Tank points to the macro-zone of the attack. Your guard has to search all of it: it's the slowest.
One zone
Tank guides your guard to a zone. The search narrows down to that zone.
8×8 m
Tank guides your guard straight to the attacker. They get there sooner.
The difference is how much they have to search. In all three, CarDefense Mobile closes the last meters: < 5 m.
More basic is not less secure: the attack is detected just the same. The only difference is how much your team has to search.
How your team gets there
01
The sensors see the attack that no camera or alarm records, and tell you which zone it is in.
02
The event appears on screen with an audible alert and its location on the site map.
03
The operator dispatches the right guard to the right place. With the handheld detector, they close the last meters.
04
On closure, what the guard observed is documented, with a record of who closed, who reviewed and who validated.
Illustration · Until your team reaches the attacker, search included, at any site size. With the system running and a trained team; it varies with the scenario.
In the field
up to88%
fewer jamming attacks
Reduction in detected attacks, not in thefts, sustained for 2 to 3 months after deployment. It happens when the team handles every alert: once attackers see the guards coming, they show up less.
Gangs arrested alongside Carabineros.
The teams of several of our clients, working with Carabineros (Chile's national police), have caught gangs with the jammer in their possession.
Attackers identified and deterred.
Most of our clients manage to deter the attacker and identify them: the vehicle's license plate, how many there were and what they looked like.
Platform
CarDefense includes the platform that manages every alert and the training of those who respond.
Act
Turns every alert into a measurable response: who was notified, who was dispatched, how long it took and what they found.
Know
Trains and certifies guards and CCTV operators, so that when the alert goes off your team knows what to do.
Understand
What your team records becomes information for making decisions: where, when and how you are attacked, and how your operation responds. Today it runs inside Mission Control.

Law 21.720
Since December 2024, Chile's Law 21.720 makes it a crime to sell, carry or use a signal jammer. Carrying one is already a crime; there is no need to wait for the theft.
Up to 53 hectares with one sensor, equivalent to a radius of 410 m. The configuration defines how much certainty you have within that coverage. One covers broadly, Sector subdivides and Hyperlocation gets down to 8×8 m.
That is the Sector configuration, with several sensors that subdivide by level. With Hyperlocation you get down to 8×8 m within the level, even in an enclosed parking garage where the signal bounces.
They all depend on the same signal the jammer attacks, and that is exactly why they are the ones that can't see it. Tank does not replace your provider; it protects what they already sold you.
Tank calibrates the sensitivity for your venue, and the handheld detector lets you confirm on the ground. There are also operating hours and scheduled muting for maintenance.
Every attack is recorded with date, time and location. By matching place and moment, the question goes from suspicion to fact.
Yes. A patrol can carry it and cover the area it travels, without fixed sensors. With fixed sensors you add around-the-clock monitoring and the alert that tells you where to look.
Yes, and it is included. Tank Academy trains and certifies the guards who use it, with unannounced drills.
With CarDefense Diagnosis we install a unit and tell you whether you are being attacked, how much and when. With that data, you decide.
