Managing a multi-unit property means dealing with keys — new tenant, new keys. Lost key? Emergency locksmith. Unit turnover? Rekey the whole thing. It's a quiet drain on operational budgets that most property managers have just accepted as "the cost of doing business."
But there's a better way: video doorbells at scale.
A growing number of property management companies are replacing traditional lock-and-key systems with smart video doorbells across their portfolios. The result? Fewer lockout calls, faster turnovers, and happier tenants.
This guide covers everything you need to know about buying video doorbells in bulk for multi-family properties.
A typical 200-unit apartment complex spends an estimated $8,000-12,000/year on key-related costs:
A wireless video doorbell mounted outside each unit lets tenants: - Unlock using their smartphone (no physical key needed) - See who's at the door via the app (even when away) - Receive package delivery notifications - Grant temporary access to maintenance staff or cleaners
For property managers, the benefits compound:
Not every consumer doorbell works for multi-unit deployments. Here's what to look for:

Most units include a tamper alarm that alerts you if the doorbell is forcibly removed. Damage rates are below 2% industry-wide. The 2% free spare parts included in bulk orders covers this.
Doorbells connect to each unit's existing WiFi network, not a building-wide system. For units without WiFi, some manufacturers offer 4G versions.
Most OEM apps let you manage unlimited doorbells from a single account. You can also assign sub-accounts for individual tenants.
Reputable OEM suppliers now offer GDPR-compliant cloud servers in EU regions and on-premise NVR support for properties that prefer local storage only.

|---|---|---|---|
| 50 units | $1,100-1,400 | $2,000-3,500 | 5-7 months |
