Cars stolen without breaking a single window.
In your parking facility, with a jammer that leaves your cameras, alarms and trackers deaf. None of them reports that it stopped hearing. The first effect of an attack is silence.
Jamming does not break your systems. It leaves them deaf.
A jammer floods the same frequencies your equipment uses. It is like trying to talk next to a speaker at full volume: nothing is broken, but nobody can hear anybody.
The car still works
Locked, alarm set, not a scratch on it. It is simply no longer where it was parked.
The camera is still on
Recording, indicator lit, seemingly normal. Transmitting to no one.
The alarm is still installed
Armed and operational. It simply cannot reach anyone.
Nothing is broken and nothing raises a flag. As far as monitoring is concerned, that vehicle simply stopped existing.
A single jammer shuts down your entire perimeter, all at once.
Different brands and technologies share the same underlying weakness: they all depend on radio frequency, and none of them warns you when its own band is blocked.
More wireless technology does not add up to more protection.
is the radius an attack can reach, depending on the unit’s power. And a low-power one still works: it just has to be closer.
From “something is happening” to “it is exactly here.”
The benefit is not technical, it is operational: instead of sending five officers to sweep an entire garage, you send the right officer to the right place.
The configuration you choose is what decides how specific the alert is. With Sector, the alert names the level — “Level -2,” as in the example below. With Hyperlocation, it also gives the spot within that level.
One
There is an attack, and which zone. The officer sweeps the zone.
Sector
Which floor or sub-zone. The officer goes to the right level.
Hyperlocation
26 × 26 feet, even in the worst case. The officer arrives almost on top of it.
Handheld
Under 16 feet. Closes the last stretch and identifies it.
is what it takes to reach the exact location of the attack, regardless of how large the facility is.
We calibrate each sensor’s sensitivity during installation. If your operation changes, we tune it again.
The alert lands on the screen your people are already watching.
There is no new system to learn and no extra console to watch. Detection arrives through the same channel your operation already uses for everything else, carrying the one fact that decides the response: which level of the facility it is happening on.
In a multi-level garage the signal passes through slabs and bounces off concrete, so “there is an attack” is the easy part and “it is on level -2” is the hard one. Triangulation between sensors is what solves it, and it is the difference between sending your people to one floor or to three.
Fixed sensors in the facility
They cover the garage permanently. Installed once, with nothing to operate: no new screens, no different patrol routes, no shift dedicated to watching them.
Handheld detectors
In use today: officers carry them on patrol. Detection moves with your people, and on the ground it narrows the spot far more than a floor plan can.
The alert, with the level marked
On the CCTV room screen and on the shift supervisor’s Android app. With that, the response stops being a blind sweep and becomes a specific instruction.
The officer stops searching and goes straight to the spot.
With a handheld detector, whoever is walking the facility knows whether the signal is getting closer or farther. That is the difference between sweeping three floors and reaching the right car while the attack is still under way.
Your team already knows what to do about a thief. What it lacks is a way to see him.
CarDefense is not one more tool in your security stack: it is the missing one. Against someone who shows up with a jammer, none of the tools the facility already bought will trigger.
Deter
With the team on alert and signage posted in the garage.
Most customers achieve this.
Identify
Specific suspects, at a specific spot in the facility.
Most customers achieve this.
Apprehend
Entire crews, with police on the scene.

arrested alongside national police in four months, at a single facility in Chile.
The people who identify and apprehend are the facility’s own staff, not Tank. The service delivers the actionable signal; the action is carried out by the people and the protocol your team already has.
A growing number of countries treat jammers as a crime in themselves.
Selling, carrying or operating one is prohibited in many jurisdictions, and enforcement has been tightening. Check what applies where your facility is.
Where that is the case, you do not have to wait for a completed theft to act — the device itself is the offense.
But without evidence of transmission there is nothing to pursue. Detection produces the record that turns a suspicion into something police can work with.
That gives your security team, and the officers who respond, a far stronger position against organized crews than a report filed the next morning.
The questions that come up before signing.
The absence of an alert is the first symptom of the attack, not proof that there isn’t one.
They all depend on radio frequency, and none of them detects when its own band is blocked. A single jammer neutralizes all of them at once.
That is the Sector configuration, which subdivides the facility by level and sends the officer to the right floor.
Every attack is logged with date, time and location. Cross-referencing place and moment turns the question from a suspicion into a fact.

We install a unit in a single day and give you the answer. It is a pure assessment: no real-time alerting and nothing for you to operate.
