An excellent purchase for your home or office is the intercom. First of all, it is convenient in that you will always see the person who came to you. Single-user systems are intended for individual use; for a large number of apartments, multi-subscription models are recommended. The sample should be fully equipped and have a good viewing angle.
In order to install and connect the COMMAX doorphone, you need to familiarize yourself with at least a minimum of information about it. On-door speakerphones of this manufacturer can be with video function, provide a color or black-and-white image (depending on the model). A set of video intercoms should include high-quality equipment that will provide good work and the ability to conduct a conversation using the handset (or over the speakerphone). The camcorder must have a speaker, microphone, and backlight.
Choosing this device, you need to pay attention to the size of the screen diagonal, as well as whether there is a built-in memory, a handset and a hands-free function. It is also quite important what type of control is implemented on the screen (using the buttons or "touch screen"). Pay attention to the fastening. Do not forget about the ability to connect additional wireless handsets, the number of units and cameras that connect to the video intercom. There are models that have a built-in quadrator (that is, they allow you to divide the screen into four parts), which allows you to monitor from multiple cameras at once. Connecting a video intercom is possible in a vertical position.
It is not recommended to install and connect the intercom in places where there is an increased activity of magnetic fields, excessive humidity, direct sunlight. The intercom should not be placed next to heating appliances. The intercom should be connected in a well-ventilated room with natural ventilation. It is forbidden to open the monitor case during its operation, and also to use cables and sockets that do not meet the device standards specified in the instructions. It is still not recommended to connect the intercom in places with a poorly reliable surface. Only on condition that the connection is correct, the product will last a long time and will not cause any complaints.
Install the intercom at a height of about 150 cm from the floor. Connect the electricity only after complete installation of the device. Eliminate the possibility of metal objects and various chemicals getting on the case or monitor!
