At a glance
The eufy Eufycam S4 2-Camera 4K Security System is a premium outdoor setup for households wanting broad coverage over key entry points. Its main strengths are the mix of wide-view 4K footage, 360 degree smart tracking, and on-device AI for people, vehicles, and pets. It is best for users who want smarter monitoring without constant false alerts. One limitation is that expandable storage requires a separate microSD card.
What it’s great for

Who it’s for
- Homeowners
- Families
- Smart Home Users
- Pet Owners
- Users Upgrading to Smarter Outdoor Security
Things to consider
It offers strong all-round outdoor coverage, but users wanting maximum long-term local storage will need to add a microSD card separately for expansion beyond the built-in 32GB.
Smart home integration score
7/10 - Strong AI-led monitoring and app-based usability, though integration details with broader smart home ecosystems are not clearly specified here.
Night vision performance
8/10 - Designed for outdoor surveillance with detailed imaging and smart tracking, making it well suited to low-light monitoring.
Outdoor weather suitability
9/10 - IP65 weather resistance makes it a strong fit for exposed outdoor areas around the home.
Pet & package monitoring fit
8/10 - Pet detection and smart tracking make it useful for monitoring pets and activity near entry points, though package-specific detection is not stated.
Installation ease
7/10 - Well suited to home installation for key outdoor zones, though positioning a multi-lens system for best coverage may take more planning than a basic fixed camera.
Key benefits
- Triple-Lens Design: Combines a fixed overview camera with PTZ tracking so you can watch a broad area and follow activity more closely.
- 4K Upper Lens: Captures sharper detail across key areas like driveways and entry points for easier identification.
- 360 Degree Smart Tracking: Follows movement around the monitored zone to reduce blind spots during active events.
- On-Device AI Detection: Recognises humans, vehicles, and pets to help cut down on unnecessary alerts.
- 130 Degree Wide View: Covers more of the scene in a single frame, making it useful for front-of-home surveillance.
- IP65 Weather Resistance: Built for reliable outdoor use in rain and dusty conditions.
- 32GB Built-In Storage: Lets you start recording locally out of the box without needing immediate extra storage.
- Expandable Storage Support: Can be expanded up to 256GB via microSD for longer retention of high-resolution clips.
Q: Can one camera watch both a doorway and driveway approach?
A: Yes. One camera combines a 130 degree 4K overview with a lower 2K PTZ that can pan through 360 degrees to follow activity. That suits a doorway plus the surrounding approach, but two cameras are better for separate front and rear zones.
Q: Do I need to buy a microSD card straight away?
A: No. The system already includes 32GB of internal storage, so it can record locally from day one. A microSD card is only needed if you want longer clip retention, and expansion supports cards up to 256GB.
Q: What motion alerts can this system actually tell apart?
A: It can tell apart humans, vehicles, and pets using on-device AI, so alerts can focus on more relevant movement. That is useful for busy entry points, but package-specific detection is not listed for this model.
Q: Is this camera kit suitable for exposed outdoor mounting?
A: Yes. E8172TW1 has an IP65 weather-resistance rating, which suits outdoor mounting around driveways, doors, and side access. It is designed for rain and exposed conditions, but that rating is not the same as waterproof submersion protection.
Q: Does the PTZ section replace the fixed wide 4K view?
A: No. The PTZ section adds tracking and closer views, but it does not replace the fixed 4K lens. The wide lens keeps a constant overview of the zone while the lower 2K PTZ follows movement within the same area.
