If you are thinking about installing a video intercom and don’t know whether to choose a WiFi model or a conventional one, this guide will help you make the best decision based on the type of installation, budget, and user needs.
What is a conventional video intercom?
A conventional video intercom transmits the video and audio signal through a physical cable between the outdoor panel and the indoor monitor. It is the most widespread technology in Spain and is used in most residential and community installations.
Tegui examples: Tegui Classe 100V16E Monitor, Tegui 2-wire System.
What is a WiFi video intercom?
A WiFi video intercom connects the indoor monitor to the home’s wireless network, allowing you to receive calls and see the door image from your mobile, tablet, or smart monitor, even when you are not at home.
Tegui examples: Tegui Classe 100X16E WiFi Monitor (Ref. 344786).
Key differences: WiFi vs conventional
| Feature | Conventional | WiFi |
|---|---|---|
| Connection | Cable (2 wires or 4+N) | Cable + WiFi network |
| Mobile reception | No | Yes, from anywhere |
| Installation complexity | Low-medium | Medium (requires WiFi setup) |
| Internet dependency | No | Yes (for remote use) |
| Price | More affordable | Higher initial investment |
| Reliability | Very high | High (depends on the network) |
| Compatibility with old installations | High | Medium |
When to choose a conventional video intercom?
- The installation already has existing wiring (2 wires or 4+N).
- It is a community of neighbors with several monitors.
- Remote access from mobile is not needed.
- Maximum reliability without depending on the internet is sought.
- The budget is tight.
When to choose a WiFi video intercom?
- The user wants to receive calls on their mobile even when not at home.
- It is a single-family home or apartment with only one unit.
- The video intercom is to be integrated with other smart home devices.
- The installation is new and can be planned from scratch.
Are WiFi systems compatible with old installations?
In many cases, yes. Tegui WiFi monitors, like the Classe 100X16E, are compatible with existing 2-wire wiring, allowing you to modernize an old installation without rewiring. Always check the equivalence table before replacing a monitor.

Frequently asked questions
Can I use the WiFi video intercom without internet?
Yes. The WiFi video intercom works normally in local mode (indoor monitor ↔ outdoor panel) even without an internet connection. Internet connection is only necessary to receive calls on the mobile remotely.
Does the WiFi video intercom consume more energy?
The additional consumption due to WiFi connectivity is minimal and does not make a significant difference in the electricity bill.
What happens if the WiFi fails?
The system continues to work in local mode. Only the remote call functionality to the mobile is lost until the connection is restored.
Is it difficult to install a WiFi video intercom?
The physical installation is similar to that of a conventional monitor. The difference lies in the WiFi network and app setup, which takes a few extra minutes but is within the reach of any installer.

Conclusion: which is better, WiFi or conventional?
There is no universally better option. The choice depends on the type of installation, user needs, and available budget. As a general rule:
- Communities of neighbors or installations with existing wiring: conventional video intercom.
- Single-family homes or users who want remote control: WiFi video intercom.
