What Is an E27 Bulb Security Camera?

An E27 bulb security camera is a Wi-Fi-enabled surveillance camera built into a standard E27 light-bulb form factor. It screws directly into any E27 socket — no drilling, no wiring, no tools — making it one of the simplest indoor security solutions for renters and homeowners who cannot modify walls or ceilings.

YI E27 Bulb Camera — Key Specifications

Features

60-Second Screw-In Installation

The YI E27 Bulb Camera fits any standard E27 light socket. Installation requires no drilling, no wiring, and no tools — screw it in, connect via the app, and the camera is live. This makes it particularly practical for rental apartments, dormitories, and hallways where wall modifications are not permitted.

355° Pan & 90° Tilt with Position Memory

The motorized pan/tilt mechanism covers 355° horizontally and 90° vertically, controlled remotely through the mobile app. The camera supports PTZ position memory, returning to a preset angle after power cycling.

Auto Motion Tracking

When motion is detected, the camera automatically rotates to follow the moving subject across the room, keeping it centered in frame.

Three Night Vision Modes

• Infrared mode: 4 IR LEDs provide discreet black-and-white surveillance up to 10 meters, minimum illumination 0.1 Lux.
• Full-color mode: 4 white LEDs illuminate the scene for color footage at night.
• Smart mode: The camera auto-switches between infrared and full-color based on ambient light conditions.

Two-Way Audio

A built-in microphone and speaker enable real-time two-way communication — talk to family members, delivery drivers, or trigger a verbal deterrent for intruders.

Local & Cloud Storage — No Mandatory Subscription

Video is stored locally on a microSD card (up to 128 GB). Optional cloud storage via Amazon Cloud is available for overseas users. There is no mandatory monthly subscription for basic recording functionality.

Network & Security

The camera connects over 2.4 GHz Wi-Fi (802.11 b/g/n) with WPA2-PSK encryption. It does not support 5 GHz networks. The omnidirectional antenna (3 dBi gain) provides stable connectivity within typical indoor ranges. Dual-stream output allows simultaneous local and remote viewing for up to 3 users, with 4-screen split view supported.

Motion Detection & Push Alerts

The camera sends push notifications to the mobile app when motion is detected. Notification intervals are configurable at 1, 3, or 5 minutes to reduce alert fatigue.
