We live in very unpredictable times as we are extremely vulnerable to safety and security issues. There is no alternative to taking precautionary measures in this matter, and people who leave it for later often fall victim to the malicious sections of the society. Therefore, it is of paramount importance that we take up the personal security in our own hands, and secure our home and family.

Most corporate organizations have a system installed wherein guests are scanned by a video camera located outside their gates, and the guest has to introduce himself and state the purpose of the visit through the intercom. Once the requirements are validated, and the security personnel are convinced about the authenticity of the person, the gates are unlocked for the guest’s entry. This might seem to be an elaborate and expensive security system, but as a matter of fact, these video door phone intercom systems are available for household purposes as well.
The installation of these systems is extremely simple and can be carried out without professional help. The system consists of an outdoor device, which is typically a camera connected to the rest of the system. Additionally, the device would contain one or multiple indoor devices, which display the video feeds from the outdoor camera. This way, if someone rings your doorbell, you get a live feed of the person standing outside your door. Moreover, the intercom system allows you to communicate with the person before you decide to let the guest in. Other accessories in the video intercom system include adapters, cables and manuals that are required for operating the device.
The outdoor device is generally designed specifically to work in different situations. They are normally resistant to heat, rain and other typical weather conditions. Additionally, these video cameras are equipped with night vision, so as to provide visibility even at night. These cameras provide multiple video angles, which is useful to get a complete view of the situation outside. The indoor kit is generally a TFT device, with features to talk on speaker mode, unlock door remotely and monitor even when the doorbell was not pressed.
