    • Question: I am very interested in what is your best product for finding hidden cameras?   What can you recommend and why?
    • Answer: A huge variety of devices for conducting covert surveillance, presented on the market today, and their availability led to the fact that they were used everywhere. Today, video cameras have compact size, their performance is constantly improving. In addition, there were wireless models with remote control, which allows you to install them in electrical appliances, home appliances, furniture, and even clothing. For this reason, the hidden camera detector is necessary not only for business owners and security personnel, but also for ordinary people.

      Varieties of detectors
      Currently, you can buy detectors of bugs and hidden cameras that perform searches in various ways.

      Optical finder
      The work of optical detectors is carried out on the principle of re-reflection. The device operates according to the following algorithm. Like other optical technology, hidden cameras are equipped with a light-sensitive element. When hit by it, the laser beams are reflected from the element and at this time it catches the detector hidden cameras. But the device registers the glare of all objects in sight of the detector. Built-in filters provide information selection.

      Electromagnetic detector
      This device for detection of hidden video surveillance scans the electromagnetic field inside the room and compares the found electrical frequencies with those that are recorded in the database of frequencies of cameras. Today, most of the cameras work on the basis of the matrix, which is an integrated chip with photosensitive photodiodes in the composition. With its help, an electric charge is generated, which falls on the processor, where the signal is formed. The processor is equipped with an oscillator designed to emit electromagnetic waves at a given frequency. On them, the device finds hidden bugs and cameras.

      Up today, the most common types of video cameras are listed below:
      - Wireline
      - Cameras with radio channel for data transmission
      - having built-in memory

      Depending on the operational situation, you can use either an Optical video camera detector or an electromagnetic hidden video camera detector. For detection of cameras that has radio channel for data transmission, HF detector ST-500 ”Piranha” is used.

    • Answer: NLJD "NR-900 EMS" is an impulse emission type NLJD, with the output power not less than 150 W, detector "Katran-Lux" is a continuous emission type NLJD, With the output not less than 1,5Wt. "ST-402 “Cayman“ on the other hand is a principally new NLJD, that emits several frequencies at the same time, 2-3GHz frequency range and the output power of such device is only 2Wt. Impulse type NLJD has a high piercing ability, are less comfortable for detection of corrosional diodes. Impulse NLJD are most effective in empty premises, continuous NLJDs can be used due to its output power corrections can be used near electronic appliances. NLJD "Кatran-Lux" has automatic setup function (in its‘ working diapason) to the frequency, on the second harmonica which has minimum interferences., which is very important when working in cities with developed systems of cell phone networks of diapasons 900/1800 MHz.
     
    • Question: What is better for protection of the power mains: noise generators or network filters?
    • Answer: Network interference suppressing filters e.g., FSP-1F-7A provides lowering the levels in working diapason from 0,1 – 1000 MHz not less than for 60 Db and protects not only from information but also protects means of office equipment from outside interferences. But for effective work it is necessary to have a grounding system (but not zeroing), where their absence significantly lowers the effectiveness. So in most situations it is more reasonable to use noise generators, for example: SEL SP-44, which does not need grounding and enabling suppression of non-sanctioned information gathering devices.
     
    • Question: Hello, please share, what do the categories mean (different from each other) of the marked premises when testing objects of informatization.
    • Answer: Marked Premises (MP) – are premises (offices, concert halls, conference rooms and so on.), specially designed for holding closed events (office meetings, discussions, conferences, and negotiations and so on.) regarding questions, that are classified as government secrets, also premises that are equipped with government links or other types of special equipment. The category of marked premises is set according to the secrecy and exploitation for these premises.
      The premises of the First category- are premises, specially designed for holding meetings with high priority or secrecy, also companies, firms, and facilities where such questions can be negotiated.
      The premises of the second category- are premises, specially designed for holding meetings of high priority and at which top Secret information is being shared.also cabinets of institution governing offices, and its‘ main subsections in which such questions can be discussed and Secret information can be shared.
      The premises of the third category- are special premises and Office rooms of the subsections of the facility, in which negotiations and discussions where Secret information is being shared , are being held. Also conference rooms which hold mass meetings and which sometimes hold closed event.
     
    • Question: Please help, in my car SEL SP-71R "Raksa" gives out  Analog 30-40-50 and more db. Can a tracking device, radio microphone or a bug be concealed in a car?
    • Answer: Such a situation is possible when there is a wireless video camera (e.g. back-view camera). Mainly, it is necessary to switch the search indicator to SEARCH MODE and move it inside and outside of the car, to find the place, where the level of signal be at maximum. The possible source of the signal can be any radio transmitting device, as well as, so called "Bug".
     
    • Question: Hello I have a technical question regarding SEL SP-71R "Raksa" – what is the scanning length of Wi-Fi Bluetooth and 2400MHz protocols, and what is displayed if we scan Wi-Fi frequency or 2400 MHz.
    • Answer: The detection range depends from reception conditions and type of device – wi-fi and Bluetooth, depending from class, work with different output power. Typical range for Bluetooth 1-3m. For Wi-Fi – 2-10 m. If the Exchange protocol is identified, then on the SEL SP-71R "Raksa" display usually this type is shown (wi-fi or Bluetooth). If not identified then only diapason is shown as 2.4 GHz
     
    • Question: Please tell, how to find a Digital „bug" in a car using SEL SP-71R "Raksa". When measuring levels we often see fluctuations, that is, in the same place every 3-4 seconds at completely different levels. Detection places are the same- 3 spots. Should we draw a map and according to it we should calculate, on the basis of the parabolic emission? 
    • Answer: First, make sure that the source of radio emission is in the car, and not outside of it(the signals of stationary sources such as Wi-Fi hotspots, radio modems, base stations of mobile networks, and others). The correct thing to do is to conduct investigation at a different location of the car, better further from base digital stations. For example outside town. If the same signals in the same place are present, then possibly there is a bug in the car. That means that in the described situation there could be a presence of a bug- it can give out different signal levels.
