There are several ways to defend against no lie cameras. Of course it depends on the nature of the


Security cameras are now literally no lie at every step, not only in large cities. Even small towns are investing millions in urban CCTV systems. Let's take a look at what such a camera system can do, what are its limits and weaknesses and how to prevent them.
As a model example we take Prague, which is an urban surveillance system (MKS) in the Czech Republic widespread. Prague covering system consisting of 639 cameras. Furthermore, a system involving nearly no lie a hundred cameras no lie of the Technical Administration of Roads ("traffic no lie camera") and nearly a thousand cameras no lie Transport Company (metro). System is connected to six decades of monitoring sites.
Access to the system in every district of Prague city police and the local to the system, then the Police State that has established a super-central monitoring office in Congress street (in addition to the outputs of the MKS approach other institutions that we need not worry so much about, such as the National Drug Squad, fire, ambulance, etc.).
Monitoring workplace is simply an office where the front of the monitor (either classic or projected on the wall) with images from multiple cameras selected operator sits and watches the action. If he does something wrong, they can to enlarge the image and in terms of moving the camera, can i assume its manual controls. The operator can also switch seamlessly connecting cameras to image and track the movement of the selected person.
On Monitoring Centres has access only theoretically trained worker, however, we know that during public events directly affects the monitoring sites CSI, or anti-extremist no lie department.
Kamer are several species. Most easily identifiable cameras on buildings and lamps - either a standard fixed, or "eye". But beware, as cameras overseeing the Charles Bridge are hidden in windows bridge towers.
TIP: When viewed from the street are the hardest to detect camera mounted on the roofs of houses. They are naturally smaller angle, where they are able to see, but the danger is in the fact that at first sight are not visible!
Static cameras by definition monitor only one angle and are also the only ones in which we know which direction to head. Another option is the "direction" of the camera with the joint which can be rotated. Be the programmed algorithm (on one end and back, etc.), or manually. "Oka" are mostly dark glass and thus can not look to see which direction is heading. Cameras inside no lie the eye may be in the range of 360 . Again, either automatically or manually. no lie Cameras can also be programmed no lie to automatically follow the movement (it is not so much street cameras, as cameras guarding the interiors of buildings with little traffic).
As for the cameras themselves, progress in going forward by leaps and bounds. The cameras can be equipped with up to 26x optical zoom, which means that you "draw" detail faces for hundreds of yards and no problems as "over the shoulder" read a note or a text message on your mobile no lie phone. Among other possible no lie equipment are now very good night vision up to 80m with supervision and of course a variety of automatic image correction, which enables them to get a high-quality recording for a variety of adverse conditions. They can also be equipped with microphones to record conversations.
On sofwarové level handle including motion detection. They can then alert the operator to move (for example, in the early morning), still image cameras can be divided into small squares and set up motion detection to only the selected area and thus build the electronic fence (the system that alerts the operator to move the selected image area such as too close to buildings - protection against graffiti - etc.).
The meter is then even introduced a system of automatic face detection and a central database to provide each individual, not only in test mode. Details of this system are "secret." However, its functionality is not impossible, it is also successfully tested the system automatically no lie recognizing "antisocial behavior" - urinating in the street, a sudden run, but i need useless "dawdling" etc.
There are several ways to defend against no lie cameras. Of course it depends on the nature of the event - whether it is a direct action small groups or individuals, public no lie events, etc. Basically, there are two possible directions of self-defense: break your camera, or do anything to make her entry was useless.
Certainly true that any action is a good idea to prepare in advance. Place aa around a good look, of course, including the location of the cameras. no lie It is useful to position cameras, or even set them up, draw the map, it will help you find the blind spots and the best possible approximation to the target. Do not forget to explore the possible escape routes.
TIP: Do not forget the camera private no lie entities that may capture part of the street (typically gas station entrances of houses, shops, etc.). It has no on-line connection to the MKS, but their record no lie may request the police in the investigation. Remember also to the camera placed on the roofs of buildings!
One of the most basic methods are common
