Using Faraday Bags in Law Enforcement

Digital evidence can make or break a case in court. Because of this, criminals have found ways to erase digital evidence, and even track their confiscated evidence. Through the use of Faraday bags and Faraday enclosures, law enforcement has a way to preserve the chain of custody.

Evidence Collection:

When an officer collects a phone or electronic device off of a suspect, that piece of evidence needs to be kept safe from tampering. Many suspects, especially in organized crime, have people in place to remotely wipe their devices if they are ever picked up. The Faraday bags offer a solution to that. A Faraday bag will block Cell, Wi-fi, Bluetooth, RFI, and GPS signals. By making use of a Faraday bag, the LEO is able to ensure that the integrity of the collected device remains intact, and is secured for forensic investigation and court evidence.


Another safety measure that is important in evidence collection is through the use of the bag’s GPS blocking. Oftentimes certain types of evidence need to be brought to off-site and private locations, so the GPS blocking capabilities of the Faraday bags are crucial to keeping these locations private and untracked.

Travel Protection:

When traveling with sensitive electronics, escorting VIPs, or transferring anything to private locations, Faraday bags are the perfect tool. Some of the primary reasons for this are as follows:

  • Protect Agency Devices from remote access
  • Protect VIP Devices from remote access
  • Hide location

Secure Rooms:

Faraday rooms are important to ensure that evidence stays protected while it is being inspected. Through the use of Faraday tents or Hard wall enclosures, evidence can be studied and sifted through without fear of tampering. Most tents and rooms are built custom in order to provide for each agency’s specific needs and requirements. Faraday tents offer a unique option, as they are able to be taken down and put up wherever they may be needed, whether in a building or in the field. Apart from being a safe evidence investigation room, these structures also serve as a secure communications hub.

Faraday bags & pouches offer law enforcement a unique security measure. Our Faraday bags ensure that criminals and suspects are unable to alter evidence or track locations and sensitive items. They are crucial to evidence integrity all the way from crime scene to courthouse. 

Whether it is a phone, tablet, laptop, or another electronic that is remotely accessible, Faraday bags are necessary to preserve the evidence and keep its contents exactly as they were the moment it got picked up by law enforcement. Remote access can wipe evidence, taking away crucial pieces of a case.

Another reason law enforcement uses these bags is for tracking prevention. Any digital evidence kept in a secure and unmarked location needs to be in a Faraday bag to prevent tracking.

Signals we block: Cell Signal, Bluetooth, GPS, WiFi, RFID, Radar, EMP

Average Range: 85dB attenuation from 400 MHz-40GHz


The #1 Law Enforcement Bag

The NX3 Series is the most popular law enforcement bag. These bags offer a full 85dB signal blocking with 3-layer shielding and a simple fold-over/velcro closure. Ideal for evidence collection and storage.


Other Law Enforcement Bags

Other bags of ours offer unique differences from the NX3 Bags, with the exact same high-level signal blocking.

JACKETS – A tougher jacket exterior for a heavier duty bag

Dry Bags – Larger, water-proof options with backpacks, duffels, and more!


Digital Forensic Rooms

Faraday Defense custom builds digital forensic rooms for law enforcement all over North America so they can safely examine evidence without threat of tampering. When digital evidence needs to be examined, it’s important that its signal is still contained from any outside reach or intervention. These rooms are available as portable tents and permanent hard wall structures, with fully customizable features.
