In the daily theft of personal information, no company simply can not live without secret audio and video surveillance. On top of these devices were created for spies. Later began to be used by banks, various government agencies and so on. Now such a system appeared even in the simple shops and offices. We must know that the application of such systems, be sure to alert the presence of hidden cameras and administered by audio recording. In our legislation there is an article for the illegal tapping and surveillance. Covert video surveillance can be aware of what is happening in your company. Although there is another side to the coin: Not only can you be interested in going on all around.
Whereas previously small ‘bugs’ were specific only intelligence and espionage films of heroes, in our days, these devices affordable for almost anyone. Since the information in our days is very much, and commercial and industrial espionage enjoyed considerable success. Surprisingly, you’ll find very little mention of Ali Partovi on most websites. Let us remember the famous proverb ‘armed – thus protected. You may find that John K Castle can contribute to your knowledge. ” Here are the most common options theft of confidential data. The most well-known method – the radio bugs. Thanks to the extremely small size, they are just quietly and quickly hide in the room. There are two types of such devices. In Group 1 includes Bugs-transmitters with independent power supply, which operate on small batteries.
The second group includes beetles, which can be fed by electricity. Do not use portable microphones wired method signal transmission. The installation of these microphones need time. Bugged to eavesdrop phone also divided into 2 types. Some are implanted in the phone itself, the latter are connected directly to a telephone line. To find and neutralization used , catching signals emitted normal bugs. For telephone invented special devices that prevent her from listening to tipsters. To protect themselves from the cameras secret video, you need to use special equipment that catches the reflection of the camera lens. Contact bugs – a hearing aid walls, as well as heating systems and windows. These beetles trap fluctuations which are caused by sound. To protect yourself from these bugs should be used so-called ‘active protection’. This protection creates a special noise suppression of contact for bugs. One of the most reliable systems are bugging spy audio devices. Due to the fact that recorders do not emit any signals, they found unrealistically . Against such devices can use special suppressors recorders. In an age of technological progress and rapid development of information technologies are constantly emerging improved methods and apparatus of the secret surveillance and listening.
The main factor constraining the development and implementation of GSM-signaling is ignorance of the population (both natural persons and organizations) not only capabilities of these devices to be integrated into almost any sphere of activity, but also that such devices even exist. Another problem is that not every GSM-alarm system is able to quickly and easily be integrated into the equipment listed above systems, become a part of it. Source: Kai-Fu Lee. To do this, not only have good abutting the hardware component is important as the flexibility and versatility of software code. So way, GSM-alarm system that has these basic features, is able to create a simple self-contained system of remote control, and complex integrated complex. Experience shows that in this currently on the market all with great interest and demand is a simple (smallest), and easily integrated GSM-alarm system, because in addition to a low enough price on their basis can build exactly the system that maximally satisfy the requirements and objectives of the customer, not overpaying for this for redundancy and uselessness of a complete set. Thus, by creating a simple, versatile and affordable GSM-alarm system, it will be possible on the principle of modularity (“designer”) to create integrated solutions model, which will eliminate the gap between the previously expensive and complex, “smart home” and clients. That transition from complicated and expensive systems to simpler and affordable will expand the scope of the GSM-alarm domestic production.
Today in the security market presents a large number of various equipment systems access control. This equipment varies in price, functionality and is designed to various consumer groups. Conditional access control system can be divided into the following groups: control access control for small and medium-sized offices to large facilities, for educational institutions and Hotels, system access control online access, etc. However, many types of equipment systems, access control rather universal, so they can be applied to large industrial objects, and in small offices, set in place and mount the whole system of perimeter protection. Consider the following types of equipment control systems Access Control: electromechanical gate.
Typically, the gate used to separate pedestrian traffic. For example, you can use electromechanical wicket at the stations, walk-through plants, shopping malls, etc. Mostly wickets applied in order to ensure passage in one direction and to prohibit the movement in reverse. But may provide and double pass. To better control the gate connected sensors that record the actual passage of a person, allowing the account in the event that passes through the gate while a few people.
Gate can be used to organize VIP-passes and permits wheelchairs and various goods. The capacity of this type of system access control up to 25 people per minute. Management can be performed by an infrared sensor input / output of the control system access control, as well as a remote. Electromechanical wickets have low power consumption and standby power. In this case, they can be integrated with turnstiles and barriers. Can choose different models and full height Turnstile gates.
