eufyCam E330 and S300 (3C) Discontinued - What to Buy Instead

If you have been looking for the eufyCam E330 or eufyCam S300, you may have noticed that neither is available in the eufy US store. Both models have been discontinued. You may also see S300 listed as eufyCam 3C; that is the same camera, while S330 is a different model.

If you already own either camera, your current setup remains functional. We continue to support E330 and S300 with firmware and eufy app updates, so discontinuation does not mean you need to replace a working system.

If you need another camera, start with two questions: Can you run power to it, and do you need 24/7 recording? The answers help you choose between a flexible standalone camera, wire-free tracking, and a larger wired system.

E330 and S300 at a Glance

The E330 and S300 covered two common needs. E330 kept a continuous timeline where power was available, while S300 made it easier to monitor a spot without running a cable.

The table below shows the core differences between these two setups.

Those differences shaped everyday use and gave each model its own strengths.

What the eufyCam E330 and S300 Did Well

Before looking at replacements, let's briefly revisit what E330 and S300 did well. The two cameras were built for different needs, so their strengths were not the same.

What the eufyCam E330 Did Well

The E330 covered the main needs of a fixed, always-on outdoor camera:

• 4K video with a 138° fixed view
• Direct power for 24/7 continuous recording
• BionicMind AI through HomeBase 3
• Local storage without a required monthly fee

These features suited people who wanted an always-on view of a busy entrance or driveway and did not mind routing a power cable to get it.

What the eufyCam S300 (3C) Did Well

The S300 focused on wire-free event recording:

• 4K video with a 135° fixed view
• Up to six months of battery life
• BionicMind AI through HomeBase 3
• Local storage without a required monthly fee

These features suited people who preferred easier wire-free installation and only needed recorded clips when motion was detected.

Where the E330 and S300 Have Their Limits

E330 and S300 have different limits around power, coverage, tracking, and system size. The points below can help you decide which improvement matters most.

eufyCam E330 limits

E330 worked well for continuous recording, but that strength came with a less flexible installation and view:

• Wired-only placement. Every camera position needed direct power and a planned cable route.
• Fixed bullet view. The camera could not pan, tilt, or track movement beyond its 138° frame.
• Higher storage use. Continuous 4K recording filled local storage faster than event clips.

These limits made E330 less suitable for people who could not run power to the camera or needed it to follow movement across a wider area.

eufyCam S300 (3C) limits

S300 was easier to place, but its battery-based design asked you to accept a shorter recording window and more maintenance:

• Event recording only. It did not provide a continuous 24/7 timeline.
• Fixed camera view. The camera could not pan, tilt, or follow a moving subject.
• HomeBase 3 required. Local storage and BionicMind depended on the hub.
• Periodic charging. It had no built-in solar panel, and battery life varied with use and conditions.

These limits made S300 less suitable for people who wanted independent operation, automatic tracking, or continuous footage without regular charging.

Together, the two cameras leave three clear gaps to solve: more flexible power, tracking beyond a fixed frame, and better control of continuous multi-camera footage. The replacements below address those needs in different ways.

Best eufyCam E330 and S300 Replacements

No single replacement follows both discontinued cameras in the same way. Start with the location, then decide whether you need a complete timeline, wire-free tracking, or a larger multi-camera system.

eufyCam S4

Best for: people who want one flexible outdoor camera with a fixed overview, close-up tracking, and a choice between solar power and wired 24/7 recording.

The eufyCam S4 adds something neither discontinued camera could provide: a fixed wide view and a separate tracking close-up at the same time. It also lets you choose solar-powered event recording or connect direct power for 24/7 recording, so the same model can fit very different camera positions.

• Keep context while tracking. Across a wide front yard, the upper 4K bullet camera holds a 130° overview while the dual 2K PTZ camera follows movement. You can see where someone came from and inspect the close-up without losing the original scene.
• Frame one person or a group. At a driveway or front entrance, auto-framing zooms in when one person approaches and widens when several people arrive together. This is useful when a fixed camera would leave faces too small or let movement exit the frame.
• Match power to the location. A side wall without an outlet can use the rechargeable battery and detachable 5.5W SolarPlus 2.0 panel for event recording. A high-traffic entrance can use direct power when a complete 24/7 timeline matters.
• Reduce unwanted alerts. Near a road, trees, or a busy sidewalk, radar and PIR work together to identify motion more precisely. Red and blue warning lights and a 105dB siren add visible and audible deterrence when activity enters a selected zone.
• Choose the storage setup you need. One S4 can use 32GB of built-in storage and a microSD card up to 256GB. If you later add more compatible cameras or want familiar-face recognition, HomeBase S380 provides centralized storage and BionicMind.

Trade-offs: S4 is larger and more complex to mount than S340. For several cameras recording continuously, it does not provide the same centralized storage and management as NVR S4 Max; its 24/7 mode also requires direct power.

SoloCam S340

Best for: people who want an independent wire-free camera that can pan, tilt, and follow motion without requiring HomeBase.

SoloCam S340 adds solar charging, pan-and-tilt tracking, and on-camera storage without making HomeBase part of the initial setup. It is a more independent option than either discontinued model, especially when one exposed area needs moving coverage rather than a fixed view or a continuous timeline.

• Cover a space from one mount. In a compact backyard or open courtyard, the camera pans and tilts to follow movement instead of watching only one fixed direction. This reduces the need to install separate cameras for adjacent areas.
• See detail across the yard. The 3K wide-angle and 2K telephoto views support 8× hybrid zoom, helping you inspect activity up to 40ft away when a standard wide view would show only a small figure.
• Use sunlight instead of cabling. On a porch post or side wall without convenient power, the removable solar panel can be positioned for better sun exposure. Two hours of direct sunlight per day can keep the camera powered, although actual solar charging depends on the weather and available sunlight.
• Operate without a hub. Built-in 8GB storage and on-device tracking let one camera work independently. HomeBase S380 remains optional if you later want compatible cameras managed together.
• Keep the setup focused. When you only need motion-triggered coverage for one gate, play area, or detached corner, S340 avoids starting with a larger camera system than the location requires.

Trade-offs: S340 records motion events rather than 24/7 footage. Its whole camera view also moves during tracking, so it does not preserve a separate fixed overview the way S4 does.

eufy PoE NVR Security System S4 Max

Best for: people managing a larger home or business who need several cameras, reliable 24/7 recording, central storage, and faster footage review.

eufy PoE NVR Security System S4 Max adds wired data, coordinated tracking, centralized high-capacity storage, and keyword footage search. Those capabilities go beyond the fixed HomeBase cameras when several buildings, entrances, or long boundaries need to operate as one continuous system.

• Keep distant cameras connected. At a perimeter gate or detached garage, one Ethernet cable carries power and data to each PoE camera. Performance does not depend on recharging a battery or maintaining strong camera-to-router Wi-Fi at every position.
• Follow movement between views. If someone moves from a driveway camera toward a side entrance, Live Cross-Cam Tracking can continue the path on another camera. This is more useful than treating each fixed recording as an isolated clip.
• Review long timelines faster. After a night of 24/7 recording, Smart Video Search lets you search for relevant footage with keywords instead of manually scrubbing through hours of video.
• Store more as coverage grows. The included 2TB hard drive can be upgraded to 16TB. An eight-port NVR can expand to 16 channels with a PoE switch, so adding ordinary bullet or turret cameras does not require replacing the recorder.
• Combine overview and close-up evidence. Each included PoE Cam S4 pairs an upper 4K wide-angle view with a lower 2K PTZ camera for tracking and zoom. At a large entrance, this keeps the full scene available while capturing closer subject detail.
• Review footage without relying on a phone. At a workshop or office, you can connect a monitor and mouse directly to the NVR for routine review. App and web access remain available when you need to check the system from somewhere else.

Trade-offs: NVR S4 Max requires Ethernet cabling for every camera and a larger initial setup than S4 or S340.

For larger properties, eufy NVR security systems keep several wired cameras and their footage together when multiple buildings, entrances, or long boundaries need to operate as one system.

Which Replacement Fits Your Setup

The table below compares the old models with the three current options by power, recording, tracking, storage, and best use.

Quick decision guide:

• One flexible camera needs tracking with solar or wired power → eufyCam S4
• Independent solar PTZ is enough without 24/7 recording → SoloCam S340
• Multiple wired cameras need continuous recording and centralized review → NVR S4 Max

What the Current Options Still Share

All three current options continue the parts of E330 and S300 that remain useful: local recording, remote access, AI-assisted alerts, and outdoor coverage. The difference is how each device delivers them.

• Local recording without a required monthly plan. S4 and S340 can save footage on the camera, while HomeBase and NVR systems can keep recordings together for several compatible cameras. You can choose a simple or centralized storage setup without making a monthly plan a requirement for basic local recording.
• Remote access when you are away. The eufy app lets you check live video, receive alerts, and review compatible recordings when you are away from home. NVR S4 Max also supports local and web access, which is more comfortable when you need to review longer footage on a larger screen.
• AI-assisted event handling. S4 and S340 can detect relevant activity on the device. HomeBase S380 adds BionicMind features to compatible cameras, while NVR S4 Max uses local AI across its wired camera system. The available recognition and tracking features change with the device, but the goal remains the same: help you find the activity that needs attention.
• Outdoor designs for different setup sizes. S340 suits one independent wire-free camera, S4 works alone or with HomeBase, and NVR S4 Max manages several wired cameras together. You can choose the level of equipment that fits the number of areas you actually want to watch.

Conclusion

You can keep using a working E330 or S300 while it still covers the right area and recording need. When your setup changes, choose S4 for flexible fixed-and-tracking coverage, S340 for independent solar PTZ event recording, or NVR S4 Max for a larger wired system.

FAQs

Are the eufyCam E330 and S300 still available in the US?

No. Both cameras have been discontinued in the US rather than temporarily going out of stock. Current listings should be checked carefully because accessories, renewed units, or third-party inventory are not the same as a new camera sold through the current eufy US lineup.

Can existing eufyCam E330 and S300 cameras still be used?

Yes. A working E330 or S300 can remain in your current system. We continue to provide firmware and app support, so you do not need to replace the camera solely because sales have ended. Replace it when your coverage or installation needs change.

What is the best replacement for the eufyCam E330 or S300?

Start with the feature you want to preserve. For E330-style continuous recording at one flexible camera position, choose S4 with direct power; for several wired cameras, choose NVR S4 Max. For S300-style wire-free use, choose S4 when you want a fixed overview plus tracking, or S340 when independent solar PTZ coverage is enough.

Can a wireless replacement record continuously 24/7?

No. Continuous recording needs a stable power supply because the camera must stay active and write footage throughout the day. Battery and solar modes conserve power by recording detected events. S4 changes to 24/7 recording only with direct power, while an NVR system uses PoE for continuous operation.

Do the replacement cameras require a monthly subscription?

No required monthly storage plan is needed for the local recording options described here. S4 and S340 can store footage on the camera, HomeBase S380 can centralize compatible devices, and NVR S4 Max records to its hard drive. Optional cloud services remain separate.

What is the difference between eufyCam S4 SoloCam S340 and NVR S4 Max?

The main difference is system design. S4 combines a fixed bullet view and PTZ tracking in one modular camera that can work alone or with HomeBase. S340 is a standalone PTZ camera whose whole view moves during tracking. NVR S4 Max is a recorder-centered system that manages several PoE cameras and their footage together.
