The BH04 PRO is a highly rated detector by TSCM Professionals and used by over 1000 TSCM Agencies since it was launched in 2021.

The device provides users with a range of professional functions that are not ordinarily available on a single device.

BH04 PRO has a built in Spectrum Analyzer, displaying signal activity in Oscillograph format.

Another great feature of BH04 PRO is the onboard Frequency counter.

Event logging functionality is also built into BH04 PRO with a built in software, once users connect the BH04 PRO to any Windows, Mac or Linux system, the software automatically generates a PDF report containing the event logging report.

LIVE SCAN, SECURITY MODE, ACTIVITY MONITOR, EVENT LOGGING, PDF REPORTING – PRO TSCM

PBN-BH04PRO is a Professional detector for TSCM and Security professionals.

Featuring two Independent channels which can work simultaneously or on their own. ANT 1: 10-2400 MHz & ANT 2: 2400MHz – 8000MHz

The PBN-BH04PRO is a professional TSCM detector with excellent performance during Live Sweeps and a constant monitoring mode which can proactively detect threats.

Extremely effective tool for combating information leakage, built to tackle sophisticated threats which utilize the internet of things – IOT.

BH04PRO has two independent search channels with separate Antennas and a built-in frequency meter which can report and identify frequencies extremely quickly.

The BH04PRO frequency meter is ideal for professionals, a TSCM sweep can sometimes be a time sensitive matter, the reporting and identification of frequencies can quickly give a Security professional key insights into the locations radio environment and certain frequencies may immediately be identified as rogue transmissions.

Example: If a TSCM sweep is being conducted, users have the ability to isolate all transmissions that are WIFI based, if the frequency meter still detects a WIFI signal, this would be an unauthorized transmission which would need to located.

The same isolation method can be used for all frequencies that BH04PRO can detect – 2G/3G/4G/5G/DECT/Bluetooth/GSM/WLAN/WIFI/GPS

Operating in Live Environments

Sometimes sterilizing an environment is not possible. In an active environment where transmissions are critical to an organizations ability to be operational, BH04 PRO can still be used by using the Background Subtraction function.

Background subtraction is important in surveys where the location may be close to something like a cell tower operating at 900 MHz.

Close proximity to this type of transmission will spike your readings. In situations like this, users can completely disable this frequency from the sweep.

Historically, TSCM systems with a GSM filter will only weaken the reception of the frequency.

Detection of Burst Signals

There are now more and more instances where modern threats being used to steal information are being configured to collect data such as audio files.

Such devices are normally activated based on sound or remotely activated devices; such systems can be set to transmit the data at a specific time via Wi-Fi/Data Plan etc.

These types of unauthorized devices are sometimes known as store and forward systems; capturing information and storing it until it is safe to transmit. Also known as Burst signals.

These types of unauthorized eavesdropping devices can collect data for long periods and then transmit them in just a few minutes.

If such a device is used correctly, the system would be set to transmit data at a time when transmission will be least likely to be detected.

These types of systems only need to be active for a few minutes to transmit the information and can then revert to sleep mode until sound is detected or the device is remotely activated.

Burst signal devices are extremely difficult to detect if configured correctly. 

Security Mode – Burst Signal Detection

Due to these technological advancements, systems like the BH04PRO are equipped with Security mode so they can be left in a location for constant monitoring of that location around the clock.

Activating the Security Mode on BH04PRO and leaving it in a high value location gives security professionals the ability to monitor the radio environment and identify potential rogue transmissions with functions like burst signals.

Presweep analysis is vital for detection of burst signals, the BH04 PRO is a widely used system in the TSCM kit and an excellent tool for performing pre-sweep analysis.

The Internet of Things – IOT

The Internet of Things (IOT) has made life easier and more convenient but mainstream use of IOT enables cybercrime and information leakage is fast becoming the biggest threat.

IOT enabled threats with burst functionality make live TSCM sweeps redundant as the sole method of detection.

Example

Corporate client has a highly sensitive meeting and requests a sweep of the room prior to the meeting commencing on the day of the meeting.

Whilst you can sweep the room for live threats and use tools on the BH04PRO such as audio modulation to sniff out some inactive threats, digital devices which are set to record at a specific time, may not be detected due to them not being activated during the sweep, they may be in sleep mode, awaiting remote activation or even configured to record only at specific times.

Understanding the locations authorized transmissions layout round the clock allows corporate security professionals to continually monitor their high value locations and ensure areas are sterilized from unauthorized transmissions.
