eufy Bullet-PTZ Cameras: PoE, Solar or Full System?

eufy, the security brand from Anker, is known for cameras that store video locally instead of charging a monthly fee, and in the last few years it has pushed hard into a clever format called the Bullet-PTZ camera. For first-time buyers, that means one camera body that watches your whole yard and zooms in on whatever moves, with footage kept at home rather than in the cloud.
The six products here split three ways: add-on PoE cameras (S4 Max, E40 and E50) that need an eufy NVR, a complete PoE system with four cameras and a recorder, and solar-powered eufyCam S4 cameras sold singly or as a 3-cam kit.

Let’s decode the jargon. A bullet camera is a fixed, tube-shaped camera that always points at the same area. A PTZ camera can pan (turn side to side), tilt (look up and down) and zoom. A Bullet-PTZ 2-in-1 stacks both in one housing: the fixed lens watches everything, and when it spots a person, the PTZ lens swings over and zooms in for a close-up. PoE (Power over Ethernet) means one network cable carries both power and video. An NVR (network video recorder) is a box with a hard drive that records all your PoE cameras. Solar models run on a battery topped up by a small panel, so no cables at all.

Price and specifications are read from the Amazon product page and can change.
eufy Security 4K PoE Cam E50,360°
Best for: Adding 4K tracking to an eufy NVR
Pros
- 4K PTZ lens with 360 tracking
- PoE runs up to 330 ft
- IP65, -20 to 50 C
Cons
- 5x digital zoom only
- NVR S4 needs firmware update
Best for: Expanding an existing eufy NVR S4 setup
Pros
- 4K wide plus 2K PTZ lens
- 8x auto-zoom, 360 degree pan
- Tracks subjects up to 164 ft
- PoE single-cable power and data
Cons
- Requires eufy NVR S4
- PoE gear not included
The eufy Security 4K PoE Cam S4 Max is an add-on Bullet-PTZ camera with three lenses. The upper 4K lens gives a fixed 122° view, while the lower 2K PTZ camera offers 8x auto-zoom and a full 360° pan. When the bullet lens detects someone, the PTZ locks on and follows them in centered close-ups from up to 164 ft away, and group tracking keeps multiple people framed.
Night vision includes starlight color without a spotlight, an optional spotlight, infrared, and HDR to avoid overexposure, with a listed night range of 65 feet. It has red and blue strobe lights, a smart siren, AI detection of people, pets and vehicles, and two-way talk with noise reduction. It is IP65 weatherproof and comes with 3-year after-sales support.
Important: this is an add-on. It requires an eufy NVR S4 to operate, plus PoE switch, injector or DC adapter as needed, none of which are included. It suits people who already own the S4 system and want another tracking camera. First-timers should start with the full 4-cam system instead.
eufy Security PoE Bullet Camera E40 for Fixed Wide Coverage

eufy Security PoE Bullet Camera E40, 4K UHD, Add-On Cam
Price and specifications are read from the Amazon product page and can change.
eufy Security PoE Bullet Camera E40
Best for: Fixed wide views on an NVR S4
Pros
- 4K UHD, 122 degree view
- IP67 weatherproofing
- Starlight color night vision
Cons
- Fixed bullet, no pan or tilt
- Requires eufy NVR S4
The eufy Security PoE Bullet Camera E40 is worth flagging clearly: it is a regular bullet camera, not a Bullet-PTZ. It records 4K UHD video with a 122° wide-angle view but does not pan, tilt or track. That makes it a good fit for spots like a side gate or driveway where you only need one steady view.
It shares the starlight color night vision, spotlight and HDR, AI human detection, red and blue strobe and noise-reducing two-way talk. It is rated IP67, a step higher than the S4 Max’s IP65, meaning it can handle temporary submersion as well as rain and snow. The listed night vision range is 50 feet.
Like the S4 Max, it is an add-on that requires an eufy NVR S4 plus PoE gear. The listing also mentions a pre-installed 2 TB hard drive and channel counts, which describe the NVR rather than this camera, so do not expect a drive in the box. Choose the E40 to fill gaps next to Bullet-PTZ cameras.

eufy Security Camera System S4 Max,4K
Best for: Homeowners wanting a complete wired system
Pros
- Four Bullet-PTZ cameras
- 8-port NVR with 2TB drive
- Live cross-cam tracking
- Smart video search, no subscription
Cons
- Wired install takes planning
The eufy Security Camera System S4 Max,4K 4-Cam kit bundles four triple-lens Bullet-PTZ cameras with an 8-port NVR and a pre-installed 2 TB hard drive, upgradeable to 16 TB. Each camera has the same 4K 122° fixed lens and 2K PTZ with 8x auto-zoom and 360° pan as the add-on S4 Max, with tracking up to 164 ft.
The system adds Live Cross-Cam Tracking, where cameras hand off a moving subject to each other, and a local AI agent that lets you set no-go zones and custom alerts. Smart video search lets you type keywords to find clips, with no subscription fee. The NVR can expand to 16 channels with a separate PoE switch; each Bullet-PTZ camera uses 2 channels, so it supports up to 8 of them. It can also connect eufy battery cameras, doorbells and sensors to use NVR features.
This is the pick for homeowners ready to run cables once and get 24/7 recording. For more background on how recorders work, see our eufy NVR system guide.
eufy Security 4K PoE Cam E50, 360° for Sharper Zoomed Tracking
The eufy Security 4K PoE Cam E50,360° is a dual-lens Bullet-PTZ add-on that flips the S4 Max’s layout. Its upper fixed lens is 2K with a 115° view, and its lower PTZ lens is 4K with 360° tracking and 5x digital zoom, capturing detail up to 65 ft away. eufy calls the tracking OmniTrack: the wide lens spots activity and the PTZ lens locks on and auto-frames.
It supports cross-cam tracking with an eufy NVR, smart video search by person, vehicle, pet or face with no subscription fee, red and blue strobe, and full-color or infrared night vision. It is IP65 and rated for -20°C to 50°C. One PoE cable delivers power and data up to 330 ft. It requires eufy NVR E50 or S4 for all features, and the NVR S4 needs firmware V4.2.2.8 or above. Mounting bracket, screws and a positioning sticker are included.
Choose the E50 if you already own a compatible eufy NVR and want the sharper lens on the tracking side. If long-distance zoom matters most, the S4 Max’s 8x zoom and 164 ft range reach farther.
eufy Security eufyCam S4 for Wire-Free Solar Coverage
Best for: Covering a whole property wire-free
Pros
- Three solar Bullet-PTZ cameras
- Cross-cam tracking
- No monthly fee per title
Cons
- Listing does not say if HomeBase included
Best for: Yards without cable runs
Pros
- 5W solar panel
- Works without a HomeBase
- 32GB built-in storage
- Radar and PIR detection
Cons
- 24/7 recording needs HomeBase S380
The eufy Security eufyCam S4 brings the Bullet-PTZ idea to a battery camera. The upper 4K bullet lens covers a 130° fixed view, and the lower dual 2K PTZ lenses give 360° tracking and 8x hybrid zoom, catching details up to 164 ft away. When more people enter the scene, it zooms out to keep them all visible.
It charges from a detachable 5.5W solar panel with SolarPlus 2.0; eufy says one hour of direct sun a day keeps it running, and the battery is 44.3 watt-hours. It works on its own with no HomeBase, with on-device AI for people, vehicles and pets, and 32 GB of built-in storage expandable to 256 GB with a microSD card (not included). Radar plus PIR motion sensors cut false alarms, and red and blue lights and a 105 dB siren deter intruders.
Pairing with a HomeBase S380 adds BionicMind AI to tell family from strangers, up to 16 TB storage, and 24/7 recording after a firmware update. It suits anyone with no easy way to run cable. Our eufy outdoor solar camera guide has more on solar placement.
eufy Security eufyCam S4 3-Cam Kit, 4K for Whole-Property Solar
The eufy Security eufyCam S4 3-Cam Kit,4K packages three solar Bullet-PTZ cameras. The listing names the same 4K 130° bullet lens, 2K dual-lens PTZ with 360° tracking, tracking up to 164 ft, 5.5W solar panel with SolarPlus 2.0, radar and PIR detection, red and blue lights and 105 dB siren. The title adds cross-cam tracking, AI recognition, 8x zoom, color night vision, local storage and no monthly fee.
The kit’s listing is thin. It says the cameras are better with a HomeBase S380 but does not say whether a HomeBase is in the box, and it does not list built-in storage per camera. Check the package contents before buying.
This kit suits larger homes that want front, back and side coverage without wiring. If you only need one angle, the single eufyCam S4 is enough.
How to Choose the Right eufy Bullet PTZ Camera
Wired or solar. PoE cameras (S4 Max, E40, E50 and the 4-Cam system) get constant power and support 24/7 recording through an NVR. Solar eufyCam S4 models skip cables but depend on sunlight.
Add-on or full kit. The S4 Max add-on, E40 and E50 do nothing on their own; they need an eufy NVR. Beginners should pick the 4-Cam system or a eufyCam S4.
Tracking or fixed. If you want the camera to follow people, choose a Bullet-PTZ model. The E40 is fixed only.
Zoom distance. The S4 Max and eufyCam S4 list tracking up to 164 ft with 8x zoom. The E50 lists 65 ft with 5x digital zoom.
Network reach. If your NVR sits far from Wi-Fi, our eufy NVR Wi-Fi module guide explains how to link battery cameras to it.
