1. What Is a Video Doorbell and How Does It Work?

A video doorbell is a smart home security device that replaces or enhances your traditional doorbell by adding a video camera, microphone, speaker, and Wi-Fi connectivity. It allows homeowners and businesses to see and communicate with visitors at their door through a smartphone or monitor, even from remote locations.

How It Works

• Motion Detection: Detects motion near your door and starts recording or sends alerts.
• Two-Way Audio: Lets you talk to visitors through your phone or intercom system.
• Live View: Stream real-time video from the doorbell camera.
• Cloud or Local Storage: Stores video footage either on the cloud or locally via SD card or NVR system.

Smart doorbells with local storage have gained popularity due to privacy concerns and subscription-free video access.

3. Do Video Doorbells Record All the Time?

Whether a video doorbell records 24/7 or only on motion depends on its storage method and software design. For local storage doorbells, this is an important feature to understand for data management and privacy compliance, especially in commercial properties, gated communities, and offices.

Recording Modes Explained

1. Motion-Activated Recording
   • Most common mode
   • Saves storage space
   • Sends alerts when movement is detected
2. Continuous Recording (24/7)
   • Requires high-capacity storage
   • Ideal for commercial premises or apartment buildings
   • Often supported by NVR-based systems
3. Event-Based Cloud Recording
   • Stores clips in the cloud after motion events
   • Requires subscription (not applicable to local storage-only models)

Local Storage & Recording Duration

Storage Capacity	Recording Mode	Estimated Duration (1080p)
16GB	Motion only	3–5 days
32GB	Motion + Events	7–10 days
64GB	24/7 (light use)	3–4 days
128GB	24/7 (heavy use)	5–7 days

Note: Some models offer loop recording, automatically overwriting the oldest files when storage is full.

Benefits for B2B Buyers

• Property Managers can monitor building entrances 24/7.
• Retailers and Offices can ensure security during off-hours.
• Distributors looking to resell to privacy-conscious markets benefit from offering local storage options.

4. Video Doorbell vs Security Camera: What’s the Difference?

While both video doorbells and security cameras serve to enhance property surveillance, each has its own distinct function, use case, and ideal installation scenario. When dealing with local storage options, understanding their differences becomes even more important—especially for B2B suppliers, real estate developers, and homeowners’ associations seeking scalable security solutions.

Key Differences Between Video Doorbells and Security Cameras

Feature	Video Doorbell	Security Camera
Primary Purpose	Visitor interaction & front-door security	General surveillance
Installation Location	At entrances or gates	Anywhere on the property (indoors/outdoors)
Communication	Two-way audio with visitor	Often has audio but not two-way
Field of View	Narrow to medium (100°–160°)	Wide angle or PTZ (pan/tilt/zoom)
Power Source	Wired or battery	Wired, PoE, or solar
Smart Features	Motion detection, app alerts, intercom	Motion zones, AI tracking, alerts
Storage Options	Cloud and/or local (SD card/NVR)	Cloud, local DVR/NVR/SD card

When to Choose a Video Doorbell

• For front-door visitor monitoring
• For package theft prevention
• For intercom functionality in apartments or villas
• When two-way communication is needed

When to Choose a Security Camera

• For complete property surveillance
• For parking lots, backyards, and hallways
• For 24/7 continuous monitoring
• When integrating with larger security infrastructures

B2B Considerations

• Real estate developers can integrate both for comprehensive smart home offerings.
• Hotels and apartments benefit from doorbells for individual units and cameras for common areas.
• Wholesalers and distributors should offer both product types to meet diverse B2C and B2B needs.

By offering a product line that includes both, brands can cater to complete security coverage, making them more attractive to commercial clients.
