Who it fits

Key specs explained

4G LTE connectivity

This hub connects to cellular networks, not just Wi-Fi. You get video protection even if your home internet goes down. It works alongside the built-in battery to keep systems running during outages. Choose this if you need reliable security in areas with unstable broadband or frequent power cuts.

24-hour built-in battery

The device contains an internal battery that lasts up to one day without external power. This ensures continuous recording and alerting when electricity is lost. It provides a safety net for critical moments. Compare this to hubs without backup power, which stop working immediately during blackouts.

32 GB built-in storage

Footage is saved directly on the hub, not in the cloud. This keeps your data private and avoids monthly subscription fees for storage. The capacity is expandable up to 16 TB via external drives. It suits users who want full control over their video archives and local processing speed.

Wi-Fi and PoE connections

The hub supports both wireless Wi-Fi and Power over Ethernet for compatible cameras. PoE offers a more stable and reliable link for fixed cameras. You must connect the hub itself to your router via Ethernet for stable operation. This dual option supports advanced setups requiring wired reliability.

Physical Design and Build Specs

The eufy HomeBase Pro S1 measures 8.66 inches in height, 4.76 inches in width, and 6.69 inches in length. It weighs nothing in the provided data, so you must check the listing for that specific number. The unit comes in a white finish. This color helps it blend into standard home interiors without drawing attention. The listing notes the model number is T9000. You should verify this matches the box you receive.

According to the listing, the device uses a battery-powered source. This aligns with its 24-hour backup battery feature. The 4G LTE connectivity means you do not rely solely on local Wi-Fi for its cellular function. However, the hub itself requires an Ethernet connection to your router for stable operation. This physical port placement matters for where you mount or place the unit. You need access to a wired network near the base.

The build supports local processing with 32 GB of internal storage. This storage is expandable up to 16 TB. The compact footprint allows placement in utility closets or on shelves. The white casing suggests a focus on discreet integration. You get a sturdy unit designed for continuous operation. The physical design prioritizes connectivity ports and ventilation over aesthetic flair. This practical layout suits technical spaces rather than living room displays.

Setup and Daily Operation Guide

Setting up this hub requires a wired connection to your router. The listing specifies you must use the included Ethernet cable for stable operation. This is a firm requirement, not an option. Once connected, the device leverages 4G LTE as a secondary or primary link. You also benefit from a 24-hour built-in battery. This power source ensures continuous video protection if electricity or internet fails. The unit processes data locally. You get faster response times because footage does not travel to the cloud first. Storage starts at 32 GB built-in. You can expand this capacity up to 16 TB using compatible media. This setup keeps your data private and secure on your own hardware. For daily use, the hub manages select eufy devices. It supports eufy POE cameras, eufyCams, battery doorbells, and sensors. You must check compatibility before adding gear. The system relies on Wi-Fi and PoE connections for these devices. Note that the hub itself stays wired. You can add eufy AI Core to unlock advanced features. This upgrade enhances detection without changing the physical setup. The white unit measures 8.66 by 4.76 by 6.69 inches. It fits into standard home surveillance layouts. You manage everything through the eufy app. The local processing means you control your records directly. No external servers store your video. This design suits users who want reliability during outages and total control over their security data.

Before You Buy This Hub

You need to verify device compatibility before purchasing. This hub works with select eufy devices, including PoE cameras, eufyCams, battery doorbells, and sensors. It does not support all eufy products. Check your existing gear against the official list to ensure seamless integration. You must also plan for storage needs. The unit includes 32 GB of built-in storage, but you can expand it up to 16 TB using a compatible drive. This allows for longer recording retention without relying on cloud services. Consider adding the eufy AI Core if you want advanced features. This hub fits best in setups where internet reliability is a concern. It complements Wi-Fi-only models by offering cellular backup. You should also ensure you have a stable power source for the battery and a wired connection to your router for initial setup. Regularly check for firmware updates to maintain security standards.

Check before you buy

• Verify your eufy cameras and doorbells are compatible with HomeBase Pro S1.
• Confirm you have an Ethernet cable to connect the hub to your router.
• Check if you need additional storage beyond the built-in 32 GB.
• Decide if the eufy AI Core is necessary for your security needs.
