What type of respirator is right for virus protection?  - Protective cover with active silver

Protective class FFP2 and FFP3 (N95)

High safety standard for shielding devices against RF (radio frequency) and EMC (electromagnetic) radiation. Shading packaging guarantees attenuation of 118 dB at 350 MHz as well as continuous attenuation of 110/100/80 dB up to 18 GHz. 

For example, they protect cases of:

- tracking the sim card location

- Tracking the location and content of MT or Tablet

- use of MT to eavesdropping 

- temporary storage of various objects

SPY SHOP SLOVAKIA - Wholesale security system

The device is designed for the detection and localization of VF bedbugs and radio equipment in the nearby zone. Profi

Most devices using radio frequencies between 50 MHz and 3.3 GHz

The device provides detection: Other Wireless Phones and Mobile GSM900/1800, UMTS (3G), CDMA450 Standards; : DECT phones; Bluetooth and Wi-Fi devices; Wireless cameras;  Radio transmitters with analog modulation (AM, FM, PM) : Radio transmitters with digital modulation and continuous carrier (FSK, PSK, etc.); Radio transmitters with broadband modulation up to 10 MHz band

The retransmitter amplifies your VF 433MHz signal and sends it at a greater distance to your receiver, alarm or garage door. You can extend the distance of your remote control to virtually anything that radio protocols allow.

If the distance between the alarm and the controller is too large, or they have too many obstacles, you can use this signal repeater to receive and transmit RF signals. The device can also long out the range of the alarm itself to the PIR detector, in addition to some branded alarms. ( untested paradox, jablotron)

This device can recognize popular wireless devices CCTV cameras, mobile phones, wireless bedbugs and mobile phone all in the 50MHz to 6.0GHz band. The device has 10 LEDs indicating signal strength. When the device detects a VF signal according to its VF signal strength, the LEDs gradually light up in sequence from green to yellow to red, and the beeping changes from slow to faster i.e. shows the strength of the signal detected. The closer you are to the VF device – the more the LEDs will light up.

GPS OnLine EU-HCT2-432, GPS system from tracking even via GSM cellphone in real time. Watch who you need and do it for free. 

 A unique GPS system that you can mount in seconds. Or you're just going to put it under the back of the car. Easy setup and subsequent real-time tracking even that is possible today. No registration and monthly fees! You only create a GSM card and follow. 

Online GPS monitoring system to your car – how does it work?

The Slovak manufacturer describes the device as the most advanced and unique system that will provide complete protection of human speech. Not all recording devices can be detected using existing methods. Remotely operated radio microphones, wired microphones, passive resonators, miniature dictaphones - virtually all of these devices cannot be detected by conventional methods. 

Even a modern mobile phone can contain a digital voice recorder; this means that any phone lying on the desktop or in your pocket could be used by an adversary to record a conversation or transmit any audio information.

Installation types for catamaran company is ready hybrid version in preference to a wireless connection that is friendly to intriér companies and significantly reduces the time and thus reduces the price of installation compared to a wired system.

Surround noise - noise in broadband electromagnetic radiation TEMPEST LGS503/449 protective systems 0.01 MHz - 2000 MHz

Noise generator. The operation of various devices (such as computers, recording technologies) may include signal generation (TEMPEST) containing classified or confidential information.

These signals can be intercepted using special equipment (USRP, spectral evaluators).  

Broadband electromagnetic radiation generator TEMPEST LGS505/451

Noise generator. TEMPEST signals containing confidential information may appear when different devices (such as computers) are in operation. These signals can be intercepted using special equipment (USRP, spectral evaluators). 

Special powerful pulse jam. In many cases, it is not desirable that the ongoing secret negotiations be recorded on hidden dictaphones. However, finding out the presence of such a common means as a dictaphone is unfortunately virtually impossible without a personal examination of the persons involved. In principle, the only protection in this situation was until recently noise generators. However, these require professional installation and adjustment, but have an unpleasant side effect – it greatly disturbs the discussion, and at the same time the counterparty is given distrust, which is not obviously appropriate in the course of trade.
