FAQ – Domofony i Wideodomofony: Kompletny Przewodnik dla Domu i Firmy

1. What is the difference between an intercom and a video intercom?

An intercom allows for voice communication, while a video intercom adds video from a camera installed at the gate or front door, enhancing security and letting you see guests before opening.

2. Does a video intercom require WiFi?

Not necessarily. Most video intercoms use wired connections, but WiFi models allow for mobile viewing on your smartphone without running network cables.

3. Which video intercom should I choose for a single-family house?

2-wire or IP wired kits featuring a 7–10 inch monitor and a FullHD camera are most recommended. They provide high stability, clear image quality, and easy connection to the pedestrian gate.

4. Can a video intercom be connected to an entry gate drive?

Yes. Most kits allow you to control both the electric strike (gate latch) and an automatic drive system without needing additional relay modules.

5. Does a video intercom work at night?

Yes, video intercom outdoor panels feature built-in IR LEDs or Full Color night vision modes, allowing clear visibility even in total darkness.

6. Can I connect a video intercom to my smartphone?

If the model supports WiFi or is an IP-based system, you can answer calls, talk to visitors, and unlock the gate via a mobile app on your smartphone.

7. How many wires are required to install a video intercom?

Modern kits frequently utilize 2-wire technology, allowing you to upgrade existing installations without breaking open walls.

8. Can I install a video intercom myself?

Yes, many kits feature intuitive DIY-friendly installation. IP and WiFi models are among the easiest to set up.

9. At what height should the outdoor panel be mounted?

The optimal mounting height is 150–160 cm (approx. 5 ft) so that the camera properly captures the face of anyone standing at the gate.

10. Are IP video intercoms better than analog ones?

IP video intercoms offer superior image quality, mobile app support, integration with surveillance systems, and stable operation. However, they carry a higher price point.

11. Can I replace an old intercom with a new one without changing the cabling?

Yes, provided you choose a 2-wire system. In most cases, it is fully compatible with existing legacy wiring.

12. Does a video intercom record video footage?

Many models record snapshots or short video clips to a local SD card or cloud storage when a visitor calls or motion is detected.

13. Can I set up motion detection notifications?

IP and WiFi models offer motion detection capabilities and send instant push notifications to your smartphone.

14. Does a video intercom work during an internet outage?

Yes – local wired calls between the door panel and internal monitor function normally. Internet access is only needed for mobile app features.

15. Can a video intercom unlock doors via a combination code?

Yes. Many outdoor door stations feature integrated RFID readers or combination keypads.

16. How do I choose a video intercom for a business or office?

For commercial properties, IP systems with multi-monitor support, access control integration, and CCTV connectivity are recommended.

17. Are video intercom outdoor panels weatherproof?

Yes. Outdoor panels carry IP54 to IP66 ingress protection ratings. The higher the rating, the greater the resistance to harsh weather conditions.

18. Is video intercom footage recorded in 4K resolution?

1080p (FullHD) is the industry standard. 4K resolution is rarely used and is typically reserved for premium enterprise systems.

19. Can I connect multiple monitors inside the house?

Yes, most systems allow connecting 2–6 indoor monitors with support for intercom calls between stations.

20. Can the outdoor panel trigger a sliding gate opener?

Yes, as long as the monitor or outdoor panel features an additional auxiliary relay output.

21. Does the video intercom camera have a wide viewing angle?

A typical camera lens offers a 100–160° field of view, covering the entire entryway and the area in front of the gate.

22. How do I protect the system from power surges?

It is best practice to install surge protectors and use dedicated power supplies with adequate safety classifications.

23. Can a video intercom integrate with an NVR security recorder?

IP models usually support RTSP streaming, allowing you to add the video intercom feed directly to NVR video recorders.

24. What are the most popular video intercom brands?

The most widely chosen brands include Hikvision, Dahua, Vidos, Eura, Bticino, and Orno.

25. Can I open the gate using an RFID card or key fob?

Yes. Models equipped with proximity readers support quick contact-free unlocking via RFID cards or key fobs.

26. Can I end a call without opening the door or gate?

Yes, video intercom monitors allow you to end the call at any time with a single button press.

27. Is it possible to connect a video intercom to a home alarm system?

Yes – in smart home ecosystems, full integration between alarms, video surveillance, and access control is achievable.

28. Can access to the video intercom app be shared with multiple users?

Yes, mobile applications support multi-user sharing across several smartphones.

29. Is it worth choosing a touchscreen monitor?

Touchscreen monitors offer intuitive navigation and sleek menus, though models with physical tactile buttons are equally reliable.

30. What is the typical lifespan of a video intercom system?

On average 7–15 years, depending on brand build quality, environmental exposure, and proper installation.
