Best Intercom Systems

We have inspected all functions of Docooler system and discovered that its unique advantage is the possibility of video monitoring. The intercom system itself consists of one base station with LCD screen, which serves as a receiver, and two outdoor units equipped with cameras. It allows seeing a visitor and talking with him or her through the intercom before unlocking the door. The size of TFT/LCD screen on the base station makes 7 inches, ensuring clear visibility of the visitor in good quality and contrast. The screen has the resolution of 480x234 and the aspect ratio of 16:9. The viewing angle makes 92 degrees. The case material is ABS plastics and aluminum alloy. Control knobs on the right side of the case are used to adjust the brightness, contrast, and loudness of the base station. What's more, the IR cameras have the feature of night vision. You will clearly see anyone even in the darkness. 

The Generic Home Intercom is a great system assuring a reliable communication between its components. It allows for enhancement with an unlimited number of additional units and setting connection via three independent channels. The buttons 1, 2 and 3 on the unit are used exactly for selection of one of the channels. Having chosen a specific channel, you can call any station by pressing the Call button. And all that channel buttons are illuminated when pressed. The Talk buttons are really big and easy to press, hence are extremely convenient. You can also lock the Talk button for continuous hand-free conversations. On top of that, the system differs from its competitors by providing an option of the station labeling for their easy identification.

This intercom system includes two stations and transmitters communicating with each other. But if you wish to add new elements into the network and expand it, you might be pleased with the information that the producer of this system, Chamberlain, has foreseen an option of its expansion anytime. It is compatible with models NDIS, NTD2, and NLS1. Chamberlain NLS2 represents a wireless system, so you will never have any troubles installing it. Just put base stations in appropriate places to be connected with the intercom system and tune them to the common channel following a simple setting procedure. The system may be placed on any flat surface or mounted on a wall. To avoid sliding of base stations on slippery surfaces, the set includes special rubber tips fixed on the station’s bottom. The maximum distance for communication between intercom units equals 1,000 feet. It is an extreme distance for intercom systems and only a few alternative systems have this feature. Choosing places for installation of the stations, you should remember that walls and other partitions significantly affect the signal quality and communication range.

After comprehensive research of the NTD 2 intercom system, we've found out that its major advantage is simplicity of installation and set-up. The system consists of two intercom units, one of which is an outdoor station and the other is an indoor one. Such layout allows comfy communication with a visitor. You will know exactly who is ringing your door bell. The internal unit can be easily attached to the wall with a double-sided adhesive band. If you want to fix it more firmly, there are special holes for this purpose on the back side. The set includes all the necessary hardware. We suggest screwing the back side to the wall first and assembling the unit afterwards. Do not forget to put batteries inside or you will have to re-assemble it once again. Set-up of the NTD 2 is done by four switches. The first switch activates the Call Mode for communication between different units of the system. You should remember that to make the sound louder, the fourth switch must be in the upper position. The sensitivity of the microphone is adjusted by the second switch. The third one is reserved for potential expansion of system functions in the future.

The Aiphone C-123L/A intercom system simply provides communication with a visitor staying at your entrance door. We would like to stress that it has a relatively convenient control. The elements are connected with wires and the system itself demands almost no effort to be installed. It is also possible to add an electronic lock to the system and open/close the door by pressing the relevant button on the system’s control panel. To make a call, it’s enough for your visitor to press a single button on the outside unit and a two-tone signal will be transmitted to the indoor unit, alerting you of a guest. No need to read manuals to make out how the system works. Everything is pretty simple and literally lays on the surface. To talk to your guest, you need to hold a button while if there’s you who’d like to speak, the button should be released. The moment the conversation has come to the end, the intercom system switches off in 20 min time automatically.
