Door intercom systems have various types based on functionality, installation method, and technology. Below are the main types categorized accordingly:
Wired Door Intercom Systems
This type of video intercom system is connected using cables such as coaxial, CAT5, or other wiring types. Wired systems often provide greater reliability and image quality due to their stable connection and are more suitable for large properties or offices.
Wireless Door Intercom Systems
These intercom systems are installed without cables by utilizing Wi-Fi or other wireless communication technologies. Without the need to lay cables, installation is faster, making them suitable for home renovation or renting. However, signal interferences may potentially affect image quality.
Video Intercom Systems
These systems offer a visual feed of the visitor or the person at the door through a screen installed inside the building, enabling the user to see and communicate with the visitor. Video intercoms can be wired or wireless and often have additional features such as recording or monitoring.
Intercom Systems Without Video
Audio-only intercom systems allow communication without visual capability. Though less informative than video systems, they are often more affordable and practical for quick communications and secure entrances.
IP-Based Door Intercom Systems
These intercom systems are connected to the Internet Protocol networks, allowing remote access, video feeds, and intercom functionalities through smartphones or computers. They are ideal for tech-savvy users and those who want flexible monitoring and communication.
Mobile Intercom Systems
Many door intercom systems connect to mobile devices, such as smartphones and tablets, which can be used to view and communicate with the intercom system. This type of intercom performs great in flexibility and convenience, especially for those who do not want to have physical screens set up in their homes or offices.
Every door intercom system has specific requirements and a set maintenance routine, ensuring it runs well and has a long life span.
Resolution
Video intercom systems widely have resolutions ranging from HD 720p to full HD 1080p. The higher the resolution, the clearer the video feed and, hence, better images of the visitors.
Screen Size
Screen sizes for video intercom systems vary from 7 to 10 inches. Larger screens give a better viewing experience but can take up more space.
Wireless Connectivity
Wi-Fi is a major technical feature of intercom video door systems, especially for wireless types. Ensure the system is connected to a stable Wi-Fi network with a minimum speed of 5 MHz for reliable video calls and smooth operation.
Camera Features
Common features of door cameras include night vision, wide-angle lenses, and motion detection. These features enable added security and better monitoring capabilities.
Two-way Audio
Many intercom systems have built-in microphones and speakers, which provide two-way audio to enable communication with visitors at the door. Specifications may also include noise cancellation for clear communication.
Regular Software Updates
Most modern video intercom systems work with smartphone applications or cloud services. Regular software updates help boost system performance, patch security loopholes, and add new features. Always check for firmware updates to keep the system in good condition.
Clean the Cameras and Screens
Over time, dust and grime are bound to accumulate on the cameras and screens, which may affect video quality. Use a soft, damp cloth to clean the screen and the camera lens regularly. Do not clean it with liquid as it may appear on the lens and affect video feeds.
Check Connections for Wired Systems
Always ensure that all cables, if using a wired system, are tightly secured. Periodical checks help identify any loose or corroded connections that might be affecting the system. Also, ensure the wiring is protected from moisture or pests.
Test the System Regularly
Periodically test all the components of the video intercom system, including the camera, monitor, and audio functions. It helps identify and fix problems like one-way audio, video lag, or no intercom functionality at all before the problems escalate.
Inspect Outdoor Units
The doorbell camera unit is exposed to weather conditions, so one must inspect the devices occasionally to ensure no water, snow, or ice damage occurs. Ensure that all seals around the unit case are tight and check for any signs of wear.
Out of all the available options, video intercoms for doors provide users with security, convenience, and flexibility. Here are some of the advantages of having such systems:
Enhanced Security
Video intercoms allow one to see who is at the door before opening, adding a level of security that audio intercoms do not provide. The ability to visually identify visitors helps prevent unauthorized entry and potential security threats.
Remote Monitoring
Most intercom systems connect to mobile devices, enabling users to monitor visitors in real time from any location. This function is very useful for those who are not at home most of the time but still need to know who has been trying to gain access.
Improved Communication
Two-way audio capabilities allow users to speak directly with people at the door. Such instant communication enables verification of deliveries, guests, or service personnel without physical presence.
Convenience and Flexibility
Most video intercom systems allow users to access and control their doors through mobile devices, making it easy and convenient. There is no need to have a physical intercom unit in either case, which can be an added plus if you have this option.
Integration with Other Security Systems
Many video intercoms are designed to incorporate other home security features, such as cameras, alarms, or access control. With the option of having everything controlled from one easy-to-use platform, it will be nice for all-around security.
Package and Visitor Monitoring
For homes, video intercoms allow monitoring of package deliveries and visitors, helping to minimize theft or 'porch piracy.' With the ability to visually verify deliveries and guests, homeowners can better manage who is on their property.
Door intercom systems can be selected based on various factors, such as purpose, environment, preferences, and general guidelines on what to consider when purchasing a product. Do the following if planning to buy one:
Assess Requirements
Decide if a video or audio system is needed and if it is a wired or wireless intercom. That will depend on the home or office size, outdoor and indoor spaces, and personal preferences. For large spaces, going for a wired system would be better and more reliable. However, for small spaces, wireless intercom can do the trick. Video intercoms provide extra security features.
Check Compatibility
If there is an existing security system at home, check its compatibility with the new door intercom. Intercoms can be integrated into other security features such as cameras or alarms, then go for one that can fit smoothly into an existing security framework.
Decide the Budget
Intercoms come in different prices depending on the features and quality. If planning to get one, think about which features are most essential and which are not. While investing in quality is a good idea, there are also good low-cost products. The price should only match the intercom's functionality and quality.
Ease of Installation
Consider the installation process, especially with wired intercoms. If the intercom is to replace an older one, a wired intercom might be easy to install. If it is the first time installing it and wiring is involved, it might be hard. Wireless intercoms are easier to install as they do not require wiring.
Review the Warranty
Check the warranty information and understand the coverage to ensure that the investment is protected against defects. A good warranty often indicates that the manufacturer is confident in the intercom system's quality and reliability.
