Outdoor home security made simple. 3-Link is the official companion app for 3-Link wireless security cameras — a value-oriented smart security brand known for its solar-powered outdoor camera and easy Wi-Fi setup. Published by Shenzhen Huayi Video Technology Co., Ltd., the 3-Link app lets you link cameras to your home network, stream live video, receive motion detection alerts, and review recorded footage from anywhere. With a focus on easy setup, value for money, and encrypted data transit, 3-Link turns an affordable outdoor camera into a connected security layer for homes, garages, driveways, and rental properties.
What Is the 3-Link App?
3-Link is a free home-security companion app available on both iOS and Android. It is the control layer for 3-Link smart security devices — primarily the 3-Link Solar Camera Outdoor Wireless, featuring 360° pan / 90° tilt coverage, a 5200mAh solar-rechargeable battery, full-color night vision, two-way audio, and motion-activated recording. The app handles device-to-network pairing, live streaming, motion alerts, playback of recorded clips, and optional cloud storage subscriptions.
3-Link positions itself under the tagline "Easy · Value · Smart", targeting homeowners, renters, small-business owners, and anyone who wants a budget-friendly outdoor wireless security camera without complicated wiring or a monthly surveillance fee.

How 3-Link Works

Who 3-Link Is For
3-Link is aimed at users who want value-for-money outdoor security without the complexity of full-house surveillance systems:
- Homeowners monitoring driveways, backyards, side gates, and garages
- Renters who need a wire-free camera that can move between apartments
- Small-business owners watching shopfronts or parking areas on a budget
- Vacation-home and Airbnb hosts checking exterior activity remotely
- Parents keeping an eye on kids playing in the yard
- Seniors and caregivers who want a simple app-based security check-in
Brand and Company
The 3-Link brand is operated out of China by Shenzhen Huayi Video Technology Co., Ltd. and sells hardware through its official site at 3-link.com and through marketplaces such as Temu. The site currently highlights the 3-Link Solar Camera Outdoor Wireless as its flagship product, with secondary items like the Finger Mouse and a VIP membership plan. Support is handled via [email protected], and the app's privacy policy is published on the 3-link.com domain.
Privacy & Trust
3-Link's Google Play data-safety card currently states that no data is collected, no data is shared with third parties, data is encrypted in transit, and users can request deletion of their data. These declarations support 3-Link's positioning as a privacy-minded, low-commitment security option — though users should still review the full privacy policy before enabling cloud storage.
