At a glance
The eufy Eufycam S4 2-Camera 4K Security System is a flexible outdoor setup for households wanting broad coverage across entry points and driveways. It suits homeowners who value detailed footage, smart tracking, and local storage without ongoing complexity. Its main strengths are wide-area visibility and on-device AI detection, but microSD expansion requires a separate card and some advanced features are better with a compatible HomeBase.
What it’s great for
- Front door monitoring
- Driveway surveillance
- Front and rear access coverage
- Outdoor home security
- Smart motion tracking
Where it works best
- Detached homes
- Townhouses
- Front entrances
- Driveways
- Side access paths
- Rear outdoor areas
Who it’s for
- Homeowners
- Families
- Pet owners
- Users upgrading from basic outdoor cameras
- People wanting local video storage
Things to consider
It offers strong all-in-one coverage, but buyers wanting the most advanced person recognition and larger long-term storage options may get more from pairing it with a compatible HomeBase or choosing a more specialised multi-camera setup.
Smart home integration score
7/10 - Strong standalone capability and smart detection, but some ecosystem and advanced AI benefits improve with compatible eufy hardware.
Night vision performance
8/10 - Well suited to detailed overnight monitoring, with the PTZ function helping maintain visibility across wider outdoor areas.
Outdoor weather suitability
IP65-rated for outdoor use, making it a solid fit for exposed home entry points and external walls.
Pet & package monitoring fit
8/10 - Good fit for homes with pets and front-door activity thanks to pet detection, wide coverage, and smart tracking around access areas.
Installation ease
7/10 - Straightforward for a capable DIY user, though placement matters to get the best overlap between wide-view and PTZ coverage.
Key benefits
- Triple-lens bullet-PTZ design: Combines fixed-view monitoring and active tracking in one system so you can watch key areas more comprehensively.
- 4K wide-angle upper lens: Captures detailed footage across a broad 130 degree field of view for clearer awareness at entry points.
- 360 degree PTZ smart tracking: Follows movement around the scene to help keep people, vehicles, or pets in view.
- On-device AI detection: Identifies humans, vehicles, and pets to reduce unnecessary alerts from general motion.
- Dual-zone monitoring: Suits layouts where you want to watch two priority areas such as a front door and driveway at the same time.
- IP65 weather resistance: Built for dependable outdoor use in rain and dusty conditions.
- 32 GB built-in storage: Lets you start recording locally without needing extra storage hardware on day one.
- Expandable microSD support: Supports storage expansion up to 256 GB for longer retention of high-resolution clips.
Q: Does the eufyCam S4 need HomeBase to work properly
A: No. eufyCam S4 can run as a standalone system, so a HomeBase is not required for recording and on-device AI alerts. Adding HomeBase S380 is mainly about expanded storage and more advanced recognition, not basic operation.
Q: Can it tell family from strangers without extra hardware
A: No. Family-versus-stranger recognition is an upgrade feature when eufyCam S4 is paired with HomeBase S380. On its own, the system uses on-device AI for human, vehicle and pet detection, so alerts are smart but less personalised.
Q: What storage do you get before adding a microSD card
A: eufyCam S4 starts with 32GB of built-in storage, so it can record locally straight out of the box. Storage can be expanded to 256GB with a microSD card, but the card is not included, which matters for longer 4K clip retention.
Q: Will the PTZ camera track movement across a long driveway
A: Yes. The lower PTZ section can lock on, track and zoom once the wide bullet lens detects a subject, which suits driveways and side access. eufyCam S4 is designed to capture detail at distances of up to 50 m in suitable conditions.
Q: Is IP65 enough for exposed outdoor mounting around the house
A: Yes. An IP65 rating suits outdoor use in rain and changing weather, so it is appropriate for mounting around entry points and driveways. It is weather resistant rather than waterproof, so it should not be placed where it can be submerged or pressure washed.
Q: Do the cameras rely on mains power every day
A: No. The cameras are designed for solar-assisted charging, using a detachable 5.5W solar panel rather than daily mains power. In suitable placement, about 1 hour of direct sunlight a day can help keep them charged, but shaded sites may need more attention.
