What Is a Dual-Lens Indoor Security Camera?

A dual-lens indoor security camera uses two separate image sensors to capture wider or more detailed coverage from a single device. Unlike single-lens cameras that rely on digital zoom or a fixed field of view, dual-lens models can combine outputs for enhanced image stitching, simultaneous wide-angle and close-up views, or redundant coverage — all without requiring multiple camera installations.

Key Specifications

Key Features

Dual-Lens 3MP Imaging

Two independent 3-megapixel CMOS sensors with 4 mm lenses each deliver a combined effective resolution of 2304 × 1296 + 2304 × 1296 pixels. This dual-sensor design provides enhanced detail and coverage compared to single-lens cameras at the same price point.

355° Pan & 90° Tilt with Position Memory

The motorized pan/tilt mechanism covers 355° horizontally and 90° vertically, controlled remotely through the mobile app. PTZ position memory ensures the camera returns to its preset viewing angle after a power interruption.

Three Night Vision Modes

• Infrared mode: 4 IR LEDs provide discreet black-and-white surveillance up to 10 meters at a minimum illumination of 0.1 Lux.
• Full-color mode: 4 white LEDs illuminate the scene for color footage in complete darkness.
• Smart mode: Automatically 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. Use the mobile app to talk to family members, instruct delivery drivers, or issue verbal warnings to intruders.

Motion Detection & Configurable Push Alerts

The camera detects motion and sends push notifications to your mobile device. Notification intervals are configurable at 1, 3, or 5 minutes to reduce alert fatigue during high-activity periods.

Local & Cloud Storage — No Mandatory Subscription

Record video locally on a microSD/TF card (up to 128 GB, sold separately). Optional cloud storage via Amazon Cloud is available for overseas users. No mandatory monthly subscription is required for basic recording.

Network & Security

The camera connects over 2.4 GHz Wi-Fi (802.11 b/g/n) with WPA2-PSK encryption. BLE is used for simplified initial setup. The omnidirectional antenna (3 dBi gain) ensures stable indoor connectivity. Dual-stream output supports simultaneous local recording and remote viewing for up to 3 users, with 4-screen split view.

Frequently Asked Questions

What makes a dual-lens camera different from a single-lens camera?
A dual-lens camera uses two independent image sensors. Each lens captures 2304 × 1296 pixels independently, providing enhanced detail and coverage compared to a single sensor splitting its resolution across a wider area.

Does this camera work with 5 GHz Wi-Fi?
No. It operates on 2.4 GHz Wi-Fi only (802.11 b/g/n, frequency range 2412–2462 MHz). BLE is available for initial setup.

What apps can I use to control it?
YIIOT, YI Smart, and ZKcam Pro — all available on iOS and Android.

How many people can watch the live feed simultaneously?
Up to 3 devices can view the feed at the same time.

Does it require a monthly subscription?
No. Local recording on microSD/TF card (up to 128 GB) is free. Cloud storage via Amazon Cloud is optional.

What certifications does it have?
CE, FCC (ID: 2BLDP-CT20X), and RoHS.

Can it be mounted on a wall or ceiling?
Yes. The included screw accessory set supports wall or ceiling mounting. Designed for indoor use only.

What power supply does it need?
5 V / 1 A DC input. A power cable is included; the adapter is not included.
