BTicino and Tegui are among the most trusted names in video door entry systems across Europe. Whether you're installing a new system from scratch or upgrading an existing one, this guide will help you choose the right components for your specific situation.
BTicino vs Tegui: What's the difference?
BTicino and Tegui are both brands owned by the Legrand Group, the world leader in electrical and digital building infrastructure. Their video door entry products are technically identical and fully interchangeable. BTicino is the primary brand in Italy, France and international markets, while Tegui is more commonly found in Spain and Southern Europe.
Understanding BTicino door entry system types
Before choosing a system, you need to identify which technology suits your installation:
| System type | Wiring | Best for |
|---|---|---|
| 2-wire BUS SCS | 2 wires only | Modern installations, renovations, multi-apartment buildings |
| Conventional 4+N | 4 or more wires | Older installations, multi-brand compatibility |
| WiFi (2-wire + network) | 2 wires + WiFi | Single homes, remote access via smartphone |
Choosing the right indoor monitor
The indoor monitor is the centrepiece of your video door entry system. Here are the key factors to consider:
Screen size
- 3.5" — Compact, ideal for small spaces or secondary monitors.
- 5" — The most popular size, offering a good balance of visibility and footprint.
- 7" — Premium option for maximum comfort, ideal as a main monitor.
WiFi connectivity
If you want to receive calls and open the door remotely from your smartphone, choose a WiFi-enabled monitor such as the BTicino/Tegui Classe 100X16E WiFi (Ref. 344786). This model is compatible with existing 2-wire installations and connects to the BTicino app for iOS and Android.
Hands-free operation
All modern BTicino and Tegui monitors feature hands-free communication, allowing you to speak with visitors without picking up a handset.
Choosing the right outdoor panel
The outdoor panel (door station) must match your environment and the number of apartments or entry points:
- Sfera New panel: BTicino's flagship outdoor panel range. Modern design, high build quality, IP44 weather resistance, wide-angle camera. Compatible with 2-wire BUS SCS systems.
- Number of call buttons: one button per apartment or entry point. Expansion modules allow scaling up to large buildings.
- Surface or flush mounting: choose based on your wall type and installation preference.
How many monitors can I connect?
In a standard 2-wire BTicino/Tegui installation, you can connect up to 2 monitors per apartment. With expansion modules and a central controller, the system can scale to manage dozens of apartments from a single outdoor panel.
Is my existing wiring compatible?
In most cases, yes. Modern BTicino and Tegui monitors are designed to be backward compatible with existing 2-wire installations. If you're replacing an older monitor, always check the compatibility table to find the correct replacement model before ordering.
Complete kits vs individual components
If you're starting from scratch, BTicino and Tegui offer complete kits that include the outdoor panel, indoor monitor and power supply — all pre-matched for compatibility. This is the easiest and safest option to avoid compatibility issues.
For more complex installations or replacements, individual components give you the flexibility to mix and match within the compatible range.
Frequently asked questions
Can I use a BTicino monitor with a Tegui outdoor panel?
Yes. BTicino and Tegui products are fully interchangeable within the same system type (2-wire or 4+N). You can mix brands freely as long as the system type matches.
Does the WiFi monitor work without an internet connection?
Yes. The monitor works normally in local mode (monitor ↔ outdoor panel) without internet. Internet is only required for remote calls and door opening via the smartphone app.
Can I add a WiFi monitor to an existing conventional system?
Yes, provided the existing system uses 2-wire BUS SCS wiring. The Classe 100X16E WiFi monitor is compatible with existing 2-wire installations and can coexist with conventional monitors on the same system.
Do I need a professional installer?
For simple replacements (swapping one monitor for another), an experienced electrician or installer can handle the job without difficulty. For new installations or complex multi-apartment systems, a specialist in BTicino/Tegui systems is recommended.
Summary: which BTicino system is right for you?
