One of the most common mistake committed, is opening the door to a stranger without prior verification. Before answering the door, it is necessary to authenticate the identity of the person at the door. Generally housewives and children have this tendency to open the door to any unknown visitor, especially salesmen. They do not have the slightest idea, that these people might be burglars in the disguise of salesmen. In a way the home owners invite danger for themselves unknowingly. However to avoid such possibilities, you can install video intercom systems to communicate with any person before opening the door. It is an access control system that is increasingly used as a home security measure. Intercoms are one way video components that allows the home owner to view the concerned person at the door before opening it. Many of these intercom systems provide you with the option of speaking to the person at the door. So you can not only view the person but also talk to him via intercom, without having to open the door. This gives you a fair idea whether or not to open the door.

Installing an intercom system is quite easy. All you need to do is install the camera outside your house near the doorbell, and the display unit or rather the monitor anywhere within your house. When someone rings the doorbell, you are required to press the intercom button, the camera will get activated and you will be able to view the person at the door. Intercoms are one of the effective tools of security systems for preventing thefts and intrusions. Even in your absence, these intercom systems can automatically view and record the arrival of any visitor along with date and time. They have integrated memory chips and sensory devices that allow them to perform such activities when you are not at home.

Even if nobody is at the door, still you go ahead and press the intercom button to view the outside of your house for safety reasons. If you feel something suspicious about a particular person outside the vicinity of your house, you can also take pictures through the intercom system by simply pressing the monitor button and holding it for few moments while it takes the photograph of the concerned person.

Intercom systems are highly recommended for people living in apartments, because majority of the intrusions take place in such places, especially when children are alone. Since intercoms are user-friendly devices, hence you can instruct your children to view through the intercom first before opening the door to a stranger. In this way you can not only safeguard your family but also inform police if you feel apprehensive about the person outside your doorstep. Before letting the person in, you can ask irrelevant questions to authenticate his identity. This will give the legal authorities the required amount of time to reach your place to get hold of the culprit. Intercom is yet another device to help you to fight against crime.
