Choosing an intercom system is not only a matter of convenience, but also the security of your home or office. The modern market offers many solutions, from classic audio systems to advanced video intercoms with internet connection. To make the right choice, it is worth considering a few key aspects.
Main types of intercoms
Audio intercoms
Audio intercoms are the simplest and most economical option among all types of intercoms. They allow you to communicate with visitors through voice communication without providing the ability to see an image of the person behind the door. These devices are ideal for those looking for a basic access control solution without the added features of video surveillance. Audio intercoms can be installed in residential and commercial buildings where there are no strict security requirements and no visual monitoring of visitors is required.
Video intercoms
Video intercoms are a more advanced option, equipped with a camera to transmit a video image of the visitor to a screen inside the room. This greatly increases security by allowing you to visually identify the visitor before opening the door. With a wide range of models available, users can choose devices with various features such as video recording, integration with smart home systems and even motion detection. Video intercoms are suitable for installation in both private homes and apartment blocks, providing a high level of control and security.
IP intercoms
IP intercoms are the most technologically advanced and multifunctional type of intercoms connected to the Internet. These devices allow you to control access remotely via a smartphone or tablet, giving you the ability to see and communicate with your visitor in real time, even when you are away from home. In addition, IP intercoms can be easily integrated with other elements of a smart home system, such as alarms or CCTV systems, to create a unified and effective security system. Thanks to their high degree of protection and flexibility of settings, IP Intercoms are ideal for those who appreciate advanced technology and want to maximise the automation of access control and home security.
Picture and sound quality
Camera resolution
A critical parameter for video intercoms is the camera resolution, which determines the clarity of the visitor’s image. Camera resolutions can range from 480p (standard resolution) to 1080p (high resolution) and even higher, providing highly detailed images. High resolution is especially important in low light conditions or when it is necessary to recognise fine details in the video.
Night vision
Night vision is an essential feature for 24/7 security. Night vision systems use infrared illumination to provide a clear image in total darkness, allowing you to identify visitors and monitor the situation around your entrance at any time of day.
Sound quality
Sound quality is essential to ensure clear two-way audio communication between host and visitor. Modern intercoms feature noise cancellation and other sound enhancement technologies to ensure clear communication without interference or noise, even in environments with intense street noise.
Installation and compatibility
Wired systems
Wired intercom systems require cabling from the entrance door to the internal control unit, which may require additional installation work, especially in prefabricated or older buildings. Despite this, they provide high communication reliability and stable audio and video transmission quality without the influence of external interference. Wired systems are ideal for facilities with high security and stability requirements, such as apartment blocks, office buildings and industrial facilities.
Wireless intercoms
Wireless intercoms offer a convenient solution for quick and easy installation without the need for wiring. They transmit audio and video signals over a distance via Wi-Fi or other wireless technologies, making them ideal for private homes or flats where ease of installation is important. However, please note that signal range and quality may be limited depending on environmental conditions, walls and other obstacles, potentially causing interference or interruptions to the system.
Compatibility with home automation system
Compatibility with existing smart home and home automation systems is an important factor in integrating the intercom into the unified ecosystem of your home. This enables access control, video surveillance and other security features to be managed through a single interface, such as a mobile app or central controller. When choosing an intercom, it’s worth making sure it supports standards and protocols that are compatible with your home automation system, such as Z-Wave, Zigbee or Wi-Fi.
Additional features
Access control
Modern intercoms can be equipped with various access control technologies, such as code keypads for entering pin codes, RFID cards and key fobs for contactless access, and biometric fingerprint scanners or facial recognition. These technologies enhance security by allowing you to control exactly who can enter a building and when.
Video recording
The ability to record video allows you to keep an archive of visits, which can be extremely useful for security and visitor identification when needed. Some systems allow data to be stored on external media or cloud storage, allowing easy access to video archives.
Remote control
Remote control via a mobile app greatly extends the use of the intercom, allowing you to see visitors and open the door even when you are away from home. This is particularly useful for controlling access for guests or services, as well as improving the overall security of the home.
Key recommendations for selecting the ideal intercom system
Identify your needs
Before making a purchase, it is important to have a clear understanding of what features you need from the intercom. Consider the level of security in your neighbourhood, the frequency of visits and your personal preferences for ease of use. Do you need a simple audio intercom or are you looking for an advanced system with video surveillance and remote access?
Research the market
There are many intercom models with different features and in different price ranges. Conduct market research to understand what options are available and compare them on key features and cost.
Observe the installation conditions
It is important to understand the technical requirements and limitations for the installation of the chosen intercom model. Do you already have cabling in place for a wired system, or do you need a wireless option? Do you have access to power in the right location? Is the chosen model suitable for your type of door or entrance?
Check compatibility with smart home
If you are using or planning to use smart home systems, make sure the intercom is compatible with your platform. This will allow you to integrate access control into your overall home management system, increasing convenience and security.
Don’t ignore quality and reliability
When choosing between budget and more expensive models, remember that quality and reliability should come first. Sometimes it is worth overpaying for a better device from a trusted manufacturer to avoid safety problems or frequent repairs.
Read reviews and testimonials
Feedback from other customers and recommendations of experts can be very useful when choosing an intercom system. They will help you learn about the actual quality of the device, the level of manufacturer’s support and possible problems you may encounter.
Plan for the future
When selecting an intercom system, consider not only your current needs but also your future needs. Can the system be expanded in the future? Is it easy to add additional cameras or integrate the device with other security systems?
By following these tips, you will be able to choose an intercom system that not only meets your current requirements, but can also be customised for future needs, providing long-term convenience and security for your home.
