Comparison • Intercom • Sydney
Ring, Eufy, and Google Nest doorbells have made video doorbells mainstream. But a professional video intercom system does something a consumer doorbell can’t: gate control, remote apartment entry, multi-unit intercom, and local recording without cloud dependency. Here’s when a doorbell is enough and when you genuinely need a proper intercom — from a Sydney installer who fits both.

What a Smart Doorbell Does (And What It Doesn't)
A consumer smart doorbell (Ring, Eufy, Google Nest, Arlo) is a camera with a doorbell button that connects to your phone via Wi-Fi. When someone presses the button or triggers motion, you get a phone notification, see live video, and can talk two-way. Some record to cloud (subscription) or local storage.
What it does well: Porch monitoring, delivery verification, visitor screening, motion-activated recording. Cost: $150–$400 for the device.
What it can't do: Control a gate or building entrance remotely, integrate with an apartment building intercom system, work reliably without internet, support multi-unit configurations, or provide on-premises recording without cloud dependency.
What a Professional Video Intercom Does
A video intercom system (Aiphone, Comelit, Hikvision, 2N, Akuvox) is a hardwired entry management system. An outdoor station at the gate or entrance connects via cable to indoor monitor(s). When a visitor presses the call button, the indoor monitor rings, shows live video, and the resident can unlock the gate or door remotely — all without internet, without cloud, and without a phone.
What it does well: Gate/door release, multi-unit apartment buildings, no internet dependency, local recording, integration with access control systems, multi-monitor households.
What it costs: $800–$2,500 installed for a residential system. $2,000–$8,000+ for multi-unit strata.
When a Doorbell Is Enough
- Standard suburban home, no gate. A Ring or Eufy doorbell at the front door handles visitor screening, delivery verification, and porch monitoring perfectly.
- Renter. Smart doorbells mount with adhesive or a simple bracket — no permanent modification. Take it when you move.
- Budget under $400. A quality smart doorbell costs $200–$350. A video intercom starts at $800 installed.
- You're happy with cloud storage. Most smart doorbells require a subscription ($3–$10/month) for video storage. If that's fine, stick with the doorbell.
When You Genuinely Need an Intercom
- Gated property. If you have a front gate and need to buzz visitors in from inside the house, a smart doorbell can't release a gate. An intercom with electric strike or magnetic lock integration can.
- Apartment building. Multi-unit intercom systems let visitors call individual apartments from a lobby panel. Ring and Eufy don't support this — they're single-unit devices.
- No internet dependency. Intercoms work on local wiring. No Wi-Fi, no cloud, no subscription. If your internet drops, the intercom still works. A smart doorbell without internet is a paperweight.
- Integration with access control. Intercoms integrate with key fob systems, PIN pads, and electronic locks. Consumer doorbells don't.
- Strata common entry. Building lobbies with call-to-unit functionality require a commercial intercom panel, not a consumer doorbell. Most body corporates won't approve a Ring on common property.

Frequently Asked Questions
Can a smart doorbell open my gate?
No — consumer smart doorbells (Ring, Eufy, Google Nest) cannot control an electric gate or door lock. They're cameras with a doorbell button. To open a gate remotely, you need a video intercom system with electric strike or magnetic lock integration.
Do video intercoms need internet?
No. Video intercoms run on local wiring between the outdoor station and indoor monitor. Internet is not required for calling, viewing, or door release. Some modern IP intercoms offer optional app access via internet, but core functionality works without it.
How much does a video intercom cost installed in Sydney?
A residential system (1 outdoor station + 1 indoor monitor + gate release wiring) costs $800–$2,500 installed. Multi-unit strata systems cost $2,000–$8,000+ depending on the number of units and monitor requirements.
Can I use a Ring doorbell in a strata apartment building?
For your own apartment door (inside your lot), generally yes. On common property (lobby entrance), no — most body corporates won't approve a consumer doorbell on shared infrastructure. Strata buildings need a proper multi-unit intercom panel for lobby-to-unit calling.
What video intercom brands do you recommend in Sydney?
For residential: Hikvision DS-KIS series (good value), Aiphone (premium Japanese reliability), Akuvox (modern IP with app). For strata: Comelit, 2N, and Aiphone are the most common commercial-grade systems installed in Sydney apartment buildings.
Do smart doorbells work without Wi-Fi?
No — smart doorbells require Wi-Fi for live viewing, notifications, and cloud recording. Without internet, the device may continue to record locally (some models) but you can't view footage or receive alerts until connection is restored. A video intercom works independently of internet.
Need a gate intercom or entry system?
We install residential and strata video intercom systems across Sydney — with gate release, multi-monitor, and access control integration.
