Protect your apartment yourself
The rapid rhythm of modern life generates not only the development of industry, but, unfortunately, the growth of crime. To protect ourselves from all sorts of street scammers and thieves, called intruders, we install metal entrance doors.
The correct choice of the design of the metal entrance door, and to such doors it is possible to carry safely the doors of elbor. Buy Doors ELBOR http://elbor.ru, if desired, it will not be difficult. The necessary accessories to it will guarantee the inviolability of the dwelling even in case of your temporary absence. What attracts the metal entrance doors? We will not be mistaken if we say that the entrance door made of metal is:
• high-quality and technological products
• reliable construction, equipped with electronic security systems
• sound fittings and anti-slip elements
• Reliable and trouble-free locks.
However, modern thieves are now excellent psychologists who know the technical features of locks and know their "weak" sides. Therefore, when protecting against penetration into the apartment, you can go in several ways:
The first, the most simple and affordable way, is to train and train Polkan - a special dog that will guard your apartment. Almost as captured in the video.
The second, more acceptable and reliable way is to install electronic security systems on the entrance doors.
Electronic security entrance door
The development of security systems, ranging from a simple and primitive eyelet built into the door at the level of the human eye, has now reached incredible heights. Modern electronic security systems, in contrast to the insured dog Polkan, are very accurate and workable at any time of the day or year.
Electronic security systems include:
• locking systems - electronic locks
• electromechanical latches
• sound alarm
• intercoms.
electronic locks
In the locking systems of electronic locks, instead of the usual key, a special type of scanning electronic device is used. Unlike locks, it is possible to open doors remotely and have an increased level of secrecy.
The "secrecy" of the electronic lock will depend on the "key", the device that unlocks the system. Of course, that the "key" of the fingerprint scanner is more reliable than the code pad or magnetic cards.
Electronic locks are divided into:
• electromechanical bolt locks
• electronic locks that do not have a keyhole
The work of electromechanical locks is based on the principle of controlling the bolt by applying voltage to the solenoid. At the time of closing the electromechanical lock, the dead bolt springs the spring and enters the reciprocal part of the lock. To open the lock, it is necessary to apply a voltage that clears the spring retainer. From the installation method distinguish overhead and mortise electromechanical locks.
The electronic lock (invisible) without a keyhole is intended for metal entrance doors of residential premises. Why is an electronic lock attractive? The lock is invisible from the outside of the front door, and it is almost impossible to visually locate its installation site. The electronic lock is controlled by:
• Using Proximity keyfob with an installed RFID card
• using a mobile phone
• using the Radio key fob
electromechanical latch
The electromechanical latch is the counterpart of the locking lock and is used with a mechanical lock. The principle of operation is no different from the general principle of the operation of an electromechanical lock. The only significant difference is that the latch has a rotary handle on the inside of the room, allowing you to open the door from the inside by applying a voltage and turning the handle of the lock.
sound alarm
The audible alarm system is installed on the keyhole of locks of the lever type and works when attempting to break into. Powerful sound siren in 100 dB. stops the thief in 90 percent, which is a good measure of shelter protection.
intercom
The most popular and demanded security system is the intercom. Using the intercom, the apartment owner can negotiate with guests without leaving his own apartment.
There are intercoms of the following types:
• audio intercom
• video intercom.
The intercom design is simple. This is the external unit (the calling panel) and the doorphone itself (the indoor unit).
The doorphone call panel is designed for installation inside and outside the room. The body of the calling panel has a shockproof and vandal-proof design and is equipped with a metal visor. The built-in lock control unit has an internal control controller, which is configured to work with one and several apartment-subscribers.
On the doorbell of the audio doorphone there is a call key and an intercom device in the form of a built-in microphone and speaker.
The indoor unit is a handset and a key for opening the door lock. In the presence of video communication, the intercom is equipped with a monitor with a black-and-white or color image. The configuration of video door entry modules in this case differs from the configuration of audiophones.
Deserved popularity is enjoyed by video doorphones brands:
• Commax
• Vizit
• How
• Gardi
• Urmet
• BPT.
And, finally, a complete solution to the security problem of your apartment are DVRs.
