Experts believe that traditional, time-tested locks, chains and peepholes on doors are good, but only up to a certain point.
Along with steel armored doors and bars, you and your valuables will be protected by the latest generation of security and alarm systems.
In particular, apartment ones are designed to warn law enforcement agencies about a threat to the lives and property of residents in the event of an attack or unauthorized entry of intruders into the house.
Attempts to de-energize the unit from the outside are futile, since the power supply is backed up by a battery or an uninterruptible power supply.
In the event of a power outage, the system will automatically notify the security service.
The configuration and equipment of security alarm systems may vary.
Depending on the size and complexity of the facility, they include means of television surveillance and audio listening, access control and management, security and fire alarm equipment, actuators, microprocessors and computers with the appropriate software.
An integrated security system usually consists of a control panel, an uninterruptible power supply, sensors of various designs, television cameras and a monitor for video surveillance, a tape recorder-video recorder, microphones and a control panel.
The hidden video surveillance security system operates from the moment the car is parked. Modern technology makes it possible to monitor the situation in the entrance of the house and apartment directly from the car cabin.
For this purpose, special equipment with a video monitor is installed in the car. The entire path of the protected person to the door of the apartment is monitored using wide-angle hidden cameras. The most important part of the equipment is the lens.
They do not produce glare and have a small input lens size, so the cameras can be installed hidden. Among the undeniable advantages of the equipment is the ability to work in any lighting conditions and even in complete darkness.
For this purpose, the corridor and the landing are illuminated by infrared spotlights mounted in the ceiling, the emission spectrum of which is not perceived by the human eye.
Fire-a-ar!
Do you doubt the reliability of the municipal fire alarm system?
In this case, special sensors can be added to the security system.
If the room is filled with smoke or the temperature rises, an alarm signal is automatically transmitted to the dispatcher's console.
This is not a cheap pleasure. However, the restoration of lost property will cost significantly more.
You can also use relatively inexpensive ultrasonic devices that monitor an area of 6 to 50 square meters.
They are installed on the ceiling and, if there is a certain concentration of smoke in the air, they emit a sound signal.
Among the disadvantages of such equipment is that it is powered from the network. Thus, if the power is turned off, it does not work.
Most often, the alarm signal is transmitted to the security service via a telephone line or a radio channel when the intruder has already begun to do his dirty work. At the culminating moment, an operational group arrives and the villain is caught. This is in theory.
In practice, everything is different.
When it comes to security alarm systems, there are no universal recommendations.
Because there are no two absolutely identical apartments.
Experts believe that in our conditions, any imported «thing» works only after appropriate modifications.
