Keeping your home safe shouldn't require complex setups or expensive subscriptions. With a low-power Wi-Fi camera or smart doorbell and the right companion app, you can monitor your front door and every corner of your home from anywhere. Onecam is the official mobile app from Shenzhen Zhilian Huitong Technology Co., Ltd. that brings comprehensive home security to your smartphone — offering real-time live monitoring, intelligent motion detection, infrared night vision, two-way voice communication, free cloud storage, and AI-powered recognition of people, vehicles, and pets.
What Is Onecam?
Onecam is a free home security app designed for both smart doorbells and Wi-Fi IP security cameras. Available on iOS and Android, the Onecam app lets you add compatible devices, watch live HD video feeds, receive instant motion detection alerts, communicate through two-way voice, and manage cloud or SD card recordings — all from a single, intuitive dashboard.
What sets Onecam apart is its strong focus on smart doorbell functionality: the app is engineered for ultra-low-power doorbells with rechargeable lithium batteries, supporting remote wake-up monitoring, instant push notifications, and real-time video calls with visitors at your door.
With a 2.1 rating on the App Store (75 ratings) and 3.5 on Google Play (794 reviews), Onecam has over 100,000 downloads and supports 11 languages including English, Japanese, Korean, Spanish, French, and Russian.

How to Set Up Onecam
Getting started with your Onecam camera or doorbell takes just minutes:
- Download the Onecam app from the App Store or Google Play
- Create an account or log in with existing credentials
- Power on your Onecam-compatible device and wait for the ready indicator
- Tap "Add Device" in the app and follow the on-screen Wi-Fi configuration steps
- Start monitoring — your live video feed appears immediately on the home screen
Important setup tips:
- Onecam supports 2.4GHz Wi-Fi only — make sure you're connecting to a 2.4GHz network, not 5GHz
- Wi-Fi names and passwords must use ASCII characters only — no Chinese characters or special symbols
- Hold the device close to your router during initial setup for best results
- For firmware upgrades, an SD card must be installed; the process takes about 5 minutes — do not power off during the upgrade
Smart Doorbell — All-Day Defense
Onecam's standout feature is its smart doorbell support with ultra-low-power design. Onecam-compatible doorbells use rechargeable lithium batteries, eliminating the need for wiring or continuous power. The app provides:
- PIR (Human Infrared) Detection — Advanced human infrared sensors trigger only when a person approaches, dramatically reducing false alerts from wind, animals, or shadows
- Instant Push Notifications — Extremely fast alarm messaging so you never miss a visitor or security event
- Remote Wake-Up — Remotely wake your doorbell camera from sleep mode to check on your entryway
- Visitor Video Calls — Answer your doorbell from anywhere in the world with real-time two-way video conversation
Cloud Storage & Local Recording
Onecam provides free cloud storage for motion-triggered recordings — a rare feature among budget security camera apps. When your camera detects movement, the clip is automatically uploaded to secure servers, giving you peace of mind even if your device is stolen or damaged. For users who prefer local storage, SD cards from 2GB to 128GB are supported (Class 10 or higher recommended for best performance). SD cards larger than 32GB should be formatted through the app before first use.
AI Smart Recognition
Onecam's built-in AI recognition is available for free on all compatible devices. The AI engine can distinguish between:
- People — Identify human presence to trigger smarter, more relevant alerts
- Vehicles — Detect cars and motorcycles entering your driveway or parking area
- Pets — Monitor animals at home without constant false alarms
This AI-powered filtering helps you focus on what actually matters, reducing notification fatigue from ordinary motion like swaying trees or passing shadows.
Platform Compatibility
The Onecam app requires iOS 9.0 or later for Apple devices. Android compatibility varies by device. The app interface is available in 11 languages: English, Danish, French, Indonesian, Japanese, Korean, Russian, Simplified Chinese, Spanish, Thai, and Traditional Chinese.
