The Faraday car cover, now with an airlock.
Meet the Mission Darkness™ CYPHERCYLENT™ Faraday Car Cover Triple Chamber. A shielded vehicle bay, a walk-in vestibule, and a rear isolation chamber in one RF shielded enclosure, so examiners can come and go for days while a seized vehicle never sees an outside signal. Built for vehicle forensics, and just as useful for connected car testing and keeping a vehicle off the grid.
A seized car is still online.
The moment a vehicle is seized, it becomes evidence. It also stays connected, and every signal it receives can change what an examiner finds.
A modern connected car carries a cellular telematics modem, GPS, Bluetooth, Wi-Fi, a digital key system, and more. Together they hold some of the most valuable digital evidence in a case, including navigation history, paired phones, call logs, event data, and door and ignition timelines. That is why vehicle digital forensics has become a core part of crash reconstruction, major crimes, and trafficking investigations.
Those same radios are open doors. Switching the ignition off does not switch them off, and pulling the battery can clear the very data you are trying to preserve. The only reliable answer is to put a continuous Faraday shield around the whole vehicle and keep it there until the examination is done. Our vehicle forensics field guide maps every radio in detail.
-
Over-the-air updates
A software update that lands after seizure can rewrite the modules you plan to examine.
-
Remote commands
Connected services can lock, unlock, start, or reconfigure a vehicle from anywhere with a signal.
-
Location reporting
Routine telematics check-ins can reveal exactly where a seized vehicle is being held.
-
New pairings
A nearby phone that connects writes new records and can push older, relevant entries out of the device list.
Every open door is a leak.
A single-chamber Faraday vehicle cover isolates a car well, right up until someone needs to get inside. Open the door and the shield is broken. Over a multi-day examination that happens dozens of times. The Triple Chamber solves it by splitting one shielded shell into three rooms, each with its own job.
-
Vehicle bay
21 x 9 x 7.5 ft internalThe subject vehicle drives in through the front wall and the shell closes around it. Sized for sedans, SUVs, pickups, and tactical vehicles, and resizable to your fleet.
-
Vestibule
4 x 4 x 7.5 ft internalA double-door airlock for examiners beside the front entrance. One door closes before the next opens, so the vehicle bay stays sealed through every entry and exit. Includes an AC power filter for its interior light and a floor panel.
-
Rear chamber
4 x 9 x 7.5 ft internalA separate shielded compartment for anything still transmitting. Phones, key fobs, and trackers recovered from the vehicle stay isolated from remote wipe, tracking, and inbound commands while work continues in the bay.
Walk in, walk out, and hand off shifts for as long as the case requires. The vehicle never knows anyone was there.
This build came fully loaded.
The unit in these photos is not the base kit. It was configured for a team that spends long days inside, with sound dampening walls, a custom filter, EMI hardened lights, heavy duty rubber floor mats for vehicles, and more. Select a number to see each upgrade in place.
-
Acoustic treatment lines the walls and ceiling of the vehicle bay. Briefings, interviews, and case discussions stay inside the enclosure instead of carrying into the garage, and the bay becomes a far calmer place to work a long shift.
-
EMI hardened LED fixtures at every corner of the ceiling light the whole cabin, trunk, and engine bay. They are built to run inside a shielded space without becoming a noise source of their own, and they draw power through the filtered wall.
-
A custom filter configuration specified for this team's tools. Shielded filter plates pass power and data through the enclosure wall without opening a signal path, and modular mounting means the ports can be reconfigured later rather than rebuilt.
-
Heavy duty rubber mats made for vehicles take the weight and turning of tires, rolling tool carts, and constant foot traffic, and keep all of it off the shielding floor underneath.
-
Leads to the shielded rear chamber, where live devices recovered from the vehicle stay isolated but within reach of the examiners working the car.
-
The examiner entrance. Step into the vestibule, close the outer door, then open the inner door into the bay. The vehicle stays sealed the whole time.
And more
In this build the rear chamber has its own lighting and filtered power, so recovered devices can stay charged while they sit in isolation.

From seizure to acquisition.
The Triple Chamber is examination bay equipment. It stands in a dry indoor space and stays deployed, so the enclosure is ready before the vehicle arrives. Here is how a case moves through it.
-
Bag the small devices
At the scene, phones, fobs, and trackers found with the vehicle go into separate, labeled Faraday bags.
At the scene -
Tow straight to the bay
The vehicle is reachable until it is inside the shield, so skip the open lot and keep the gap between seizure and enclosure short.
In transit -
Drive in and seal
Drive in slowly, shut the engine off, close the front wall, and log the time isolation began.
Vehicle bay -
Quarantine live devices
Anything still transmitting moves into the rear chamber, isolated but close to hand.
Rear chamber -
Acquire inside the shield
Examiners enter through the vestibule and run forensic tools through the shielded filter connections, so the vehicle never sees an outside signal.
Vestibule and bay -
Hold and record
Keep every chamber closed between sessions and log each entry, exit, and connection for the chain of custody record.
Every session
General guidance only. Follow your agency's evidence handling policy, your examiner's direction, and applicable law.
Built for teams that work the car.
Any investigation that depends on what a vehicle remembers benefits from holding it in a controlled RF environment for the full length of the examination. See the full vehicle forensics collection.
-
Crash reconstruction
Preserve event data, location, and paired phone activity to establish speed, timing, and distraction.
-
Major crimes
Place a vehicle, and the people in it, at a scene and along a route without the record changing under you.
-
Narcotics and trafficking
Map repeat routes, stops, and the devices that traveled together, from a vehicle that cannot phone home.
-
Counter-surveillance
Sweep a vehicle for covert GPS trackers where ambient signal cannot mask a transmitter or trigger one to report.
-
Fleet and insurance
Verify claims, usage, and incident timelines on commercial and private vehicles with the data held steady.
-
Missing persons
Recover recent destinations and connection history when hours matter, before a remote update or new pairing can overwrite them.
One shielded bay, many missions.
A vehicle that cannot send or receive a signal is valuable to far more than investigators. The same Triple Chamber gives engineers, security teams, and fleet operators a controlled RF environment sized for a full vehicle, with a vestibule so people can work inside without breaking isolation.
-
Connected vehicle testing
Automotive engineers and security researchers can control exactly what a vehicle hears. Validate over-the-air update behavior, test how telematics handles a lost connection, see what a car does when GPS drops out, and research keyless entry and relay attack exposure. Test equipment connects through the shielded filter plates, so nothing outside leaks into the results.
OTA update validationTelematics failoverGPS loss testingKeyless entry research -
Tracking prevention
A hidden GPS tracker in the frame, the cargo, or a bag on the back seat cannot report its position while the vehicle is parked inside the shield. Neither can the vehicle's own telematics. That makes the enclosure a practical way to hold a recovered stolen vehicle, a sensitive shipment, or anything else whose location should stay private. For carrying items on the move, pair it with Faraday bags.
Hidden GPS trackersBluetooth item tagsTheft recoveryCargo privacy -
Sensitive operations
Keep prototype and pre-release vehicles from reporting telemetry and location before launch. Give executive protection teams a quiet space to sweep a principal's vehicle. Hold government and security vehicles fitted with sensitive equipment where nothing on board can be reached remotely, and where sound dampening keeps conversation inside.
Prototype vehiclesExecutive protectionVehicle sweepsSecure holding -
Asset protection
Shield military and fleet vehicle electronics during storage, maintenance, and standby, so navigation, comms, and engine control come out intact and mission ready. Add the EMP surge arrester option where inbound pulse protection on the power line matters, or see the single-chamber EMP Faraday Car Cover for straightforward holding.

The Triple Chamber is a stationary enclosure for a dry indoor space. Tracking protection applies while the vehicle is inside, and the enclosure provides RF isolation rather than an anechoic test environment.
Additional features you can add.
The standard Triple Chamber is a starting point. Every enclosure is built to order, and each of these can be specified to your bay, your vehicles, and the way your examiners work.
-
Custom dimensions
Length, width, and height sized to the vehicles you handle and the building you are deploying into.
-
Chamber layout
Vestibule and rear chamber sizes, door placement, and how the chambers connect, set to your workflow.
-
Additional shielded ports
Ethernet, DC power, USB Type-C, fiber, and RF connections in the quantity and placement you specify.
-
EMP surge arrester
A power filter with an integrated EMP surge arrester on the AC line, where inbound pulse protection matters too.
-
Sound dampening
An exterior cover, an interior liner, or both, so conversation inside does not carry into the room around it.
-
Interior lighting
LED lighting along the ceiling, powered through a shielded filter, so the whole cabin and engine bay are visible.
-
Vents and fans
Shielded honeycomb air vents with blower fans move air through the shield without opening a signal path.
-
ErgoLayer™ flooring
An upgrade from the standard floor mat with comfort underfoot, abrasion resistance, and conductive ground continuity.
-
Shielded windows
RF shielded viewing windows in a door or wall, so supervisors can see in without opening the enclosure.
-
Waterproof cover
An exterior cover that protects the shielding fabric from rain, snow, wind, and UV outside a controlled indoor space.
-
Fire-retardant fabric
TitanRF Flame Retardant Faraday Fabric in place of the standard layer, where facility fire codes call for it.

Engineered around what fails.
Traditional shielded tents fail in predictable places. Stitched seams tear, zippered doors leak, and filters cannot change once the enclosure is built. The CYPHERCYLENT platform was designed against each of those failure modes, and the Triple Chamber uses the same architecture as every tent in the Faraday tent lineup.
TitanRF materials are lab certified to MIL-STD-188-125 and IEEE 299-2006. See our testing and certifications.
What shielding does not do
A Faraday enclosure stops new signals from reaching the vehicle. It cannot reach data already synced to a manufacturer's servers, so preserve that separately through the appropriate legal process.
It also does not stop a recording or log already running locally inside the vehicle. It prevents remote access, not activity already in progress.
-
Non-stitched TitanRF fabric
A copper and nickel composite shell bonded with conductive TitanRF Tape at every joint. No thread holes, no leak path, and punctures repair in minutes with the patches and tape included in every kit.
-
RFMagLink™ magnetic doors
Patent pending closures with three rows of magnets for redundancy. They pull into a uniform seal on contact, so shielding never depends on whoever closed the door last.
-
Modular filter plates
CE certified shielded filter plates pass power, Ethernet, and USB through the wall. Plates come out and go back in without breaking the shielded wall.
-
Carbon fiber frame
Lightweight, non-corroding poles with patent pending modular aluminum connectors. Self-standing, and the only hand tool needed is a 3mm Allen wrench.
Faraday car cover questions.
What is a Faraday car cover?
A Faraday car cover is an RF shielded enclosure large enough to hold a whole vehicle. Its continuous conductive shell blocks cellular, GPS, Bluetooth, Wi-Fi, and key signals from reaching or leaving the car, which keeps a seized vehicle's digital evidence in the state it was found.
How is the Triple Chamber different from the EMP Faraday Car Cover?
The EMP Faraday Car Cover is a single shielded chamber, well suited to holding a vehicle in isolation between sessions. The Triple Chamber uses the same size vehicle bay and adds a double-door vestibule and a rear chamber, so examiners can enter and exit without breaking isolation and live devices have their own shielded space.
Why not just disconnect the vehicle battery?
Cutting power can clear volatile data, create new fault records, and change the state an examiner needs to capture. Many telematics units also carry a backup battery, so the radio may stay alive anyway. Isolating the radios preserves the vehicle without forcing a power decision at the scene.
Can the enclosure be set up at the scene?
No. The Triple Chamber is designed to stand in a dry indoor space, such as an examination bay or evidence garage, and stay deployed. At the scene, bag phones, fobs, and trackers in Faraday bags and tow the vehicle directly to the enclosure.
What vehicles does it fit?
The standard vehicle bay measures 21 ft long, 9 ft wide, and 7.5 ft high, which fits most cars, SUVs, and pickups. Every unit is built to order, so the bay can be resized for vans, larger trucks, or tactical vehicles.
Can examiners run forensic tools inside?
Yes. Shielded filter plates pass power, Ethernet, USB, and other connections through the wall, so tools inside the bay can be powered and networked without opening a signal path. Additional ports can be specified with your build.
Can it be used for automotive testing?
Yes. The Triple Chamber gives engineers and security researchers a shielded space large enough for a full vehicle, for work such as over-the-air update validation, telematics and GPS loss testing, and keyless entry research. Test equipment connects through shielded filter plates. It provides RF isolation, not an anechoic test environment.
Does it stop a vehicle or its contents from being tracked?
While the vehicle is parked inside, yes. GPS trackers, Bluetooth item tags, and the vehicle's own telematics cannot report a location through the shield. Protection ends when the vehicle leaves the enclosure, so use Faraday bags for items that need to stay private on the move.
Does the pictured unit come standard?
No. The build in these photos includes upgrades such as sound dampening walls, a custom filter, EMI hardened lights, and heavy duty rubber vehicle floor mats. Price any combination in the tent configurator or request a quote.
How long does it take to get one?
Each enclosure is built to order, typically in weeks rather than months. Larger and customized builds can take longer. Contact us for the current lead time.
