Video Intercom Not Working? Common Problems and Quick Fixes

You hear the buzzer but can't see who's there. Or you can see them but can't hear a word. Intercoms are meant to be effortless, so when they fail it's frustrating. Many problems have simple causes. Here is a quick troubleshooting guide from Auztech Security, the team behind hundreds of intercom installation Melbourne jobs.

Problem 1: No Picture

  • Check the power: is the monitor switched on and plugged in?
  • Wipe the camera lens: dirt, spider webs and condensation blur the image
  • Look for glare: direct sun can wash out the screen
  • Check brightness settings on the indoor monitor

Problem 2: No Sound or Poor Sound

  • Check the volume on both the monitor and the door station
  • Look for cable faults: damaged or poor-quality cable causes crackling
  • Check for water ingress around the door station

Problem 3: The Door Won't Release

  • Test the release button at the monitor
  • Check the lock or gate motor is powered and not jammed
  • Inspect the wiring at the lock for loose connections

Problem 4: Calls Don't Reach My Phone

For IP intercoms:

  1. Check that your Wi-Fi is working at the door
  2. Confirm app notifications are allowed on your phone
  3. Restart the intercom and your router
  4. Update the app and firmware

Problem 5: It Works Sometimes

Intermittent faults are usually caused by loose connections, a weak power supply or a poor network signal. These are worth fixing early, before they fail completely.

When to Call a Professional

If the quick checks don't help, or you see damaged cable, water inside the unit or a burning smell, switch it off and call a technician. A video intercom installation expert can test cables, power and network properly.

Prevent Problems Before They Start

  • Use quality cable and correct power supplies
  • Mount the door station out of direct sun and heavy rain
  • Keep your Wi-Fi network stable for IP models
  • Service the system every year or two

Upgrading an Old System

If your intercom is old, a modern HiLook or Dahua model gives sharper video, phone answering and better reliability. We can often reuse existing cabling.

Quick FAQ

Is it worth repairing an old intercom? If the fault is simple, yes. If it's very old, upgrading often makes more sense.

Do you service intercoms you didn't install? Yes, after a quick check.

The Best Home Security Camera System in 2026: An Installer’s Honest Comparison

Image
  The Best Home Security Camera System in 2026: An Installer’s Honest Comparison Every “best security camera” article you’ve read was written by someone who has never drilled a hole in a wall. They rank cameras by spec sheet. We install these systems in Melbourne homes every week, then get called back when something doesn’t work — which teaches you very different things about which cameras are actually good. This is a straight comparison of the four brands we install: Dahua , Hikvision , HiLook and Uniview . We stock all of them. We have no reason to push you toward one. First: The Thing Nobody Tells You The brand matters less than the install. A $2,000 camera system mounted at the wrong height, aimed at the wrong angle, with the recorder sitting in plain sight by the front door, is worse than an $800 system installed properly. The three things that actually determine whether your cameras identify an intruder: Height and angle. Cameras mounted too high see the top of a head. 2.5-3...
