The device is an evolution of other well-known devices: walkie-talkies, electronic intercoms and viewers – the latter less high-tech. What did he do? Simple: it allows you to see, hear and talk to whoever is at the door of your home or business, in addition to picking the lock without having to go there.

This innovation is very useful today. The reasons are many, and we'll break them down for you and help you understand why this type of equipment is highly recommended for your property.
I already have an intercom, but should I invest in a video intercom?
The answer is simple: yes! An intercom (or doorphone) is used to answer calls from your door without leaving the property. It is an important “hand on the wheel”, but it could offer more comfort and safety. Unfortunately, the number of malicious agents has increased in Brazilian cities. In an attempt to break into a home, office or business, many people look for loopholes in security and access control systems to commit crimes without being detected. One of the most common techniques is impersonating another person.
When the only way to communicate with the outside world is the voice channel, you have to trust what the other person says. If she claims to be a friend or service provider and the gate or door is opened, the situation could get out of hand. In these cases, an information check can be useful (asking for documents or asking key questions), but it is not the safest method.
With video intercoms, this risk is eliminated at the first contact. The external part of the device has a camera that sends images from the moment the bell button is pressed to an internal module with a color screen. There are also models that allow you to view the external environment on an internal screen 24 hours a day, and others that can be remotely monitored through a smartphone application via a Wi-Fi connection.

Current video intercoms are modern and allow the transmission of voice and image through what is known as 4 wires. This type of installation normally uses network cables, but it depends on the distance between the indoor and outdoor modules. This allows you to use the same structure as your existing piping – in many cases keeping the same holes used by previous equipment.

For example, a camera built into the external module has night vision, allowing you to see who is on the phone even in the dark. In addition, special LEDs located around the lens emit infrared light, increasing the perceived clarity of the device without attracting the attention of the human eye. The doorbell activation button, which plays the video intercom indoors or in your small business, is also illuminated to facilitate its location in the dark.
Wi-Fi video intercoms are best for anyone who is constantly on the go or travels a lot. With them, everything can be monitored from a distance through an application on your smartphone. From anywhere in the world, you can remotely view, reply, chat and unlock.
The indoor video intercom module can be installed in the most convenient home or business area you can imagine. It can be in the kitchen, living room, home office area and much more.
The most advanced video intercom has up to four channels of video input and two channels of blocking output. This makes it possible to open two doors (for example, one for a garage and one for pedestrians) by means of specific keys on the module inside the device.
