We live in very unpredictable times as we are extremely vulnerable to security and safety issues. There is no alternative but to take precautionary measures in this matter, and people who procrastinate often fall victim to malicious sectors of society. Therefore, it is of the utmost importance that we take personal security into our own hands and protect our home and family. Fortunately, rapid technological advances have provided us with electronic gadgets that can help us live a safe life. Devices like video door entry intercom systems are a welcome replacement for the traditional doorbell system, as they help us prevent unwanted people from gaining access to our homes.

Most corporate organizations have a system in place where guests are scanned by a video camera located outside their doors, and the guest must introduce themselves and state the purpose of the visit over the intercom. Once the requirements are validated and security personnel are convinced of the authenticity of the person, the doors are unlocked for guest entry. This may seem like an elaborate and expensive security system, but in fact, these video door phone intercom systems are also available for home purposes.

The installation of these systems is extremely simple and can be carried out without professional help. The system consists of an external device, which is usually a camera connected to the rest of the system. In addition, the device would contain one or more inner devices, which display the video feeds from the outer camera. This way, if someone rings your doorbell, you get a live feed from the person outside your door. Also, the intercom system allows you to communicate with the person before they decide to let the guest in. Other accessories of the video door entry system include adapters, cables and manuals necessary for the operation of the device.

The outdoor device is usually specifically designed to work in different situations. They are normally resistant to heat, rain and other typical weather conditions. Also, these video cameras are equipped with night vision, to provide visibility even at night. These cameras provide multiple video angles, which is useful for getting a full view of the outside situation. The interior kit is usually a TFT device, with functions to speak in speakerphone mode, unlock the door remotely, and monitor even when the doorbell has not been pressed.
