eufy - PoE NVR S4, 24/7 Recording, 16CH, 2TB HDD, 2 Bullet‑PTZ + 2 Turret, 360° PTZ, AI Tracking, Smart Search, Color Night

Yes, both camera types can be ceiling mounted: Turret cameras: Designed for ceiling mount (included bracket provides a flush or low-profile mount). BulletPTZ cameras: Can be ceiling mounted, but require flipping the camera 180° in the app settings after installation to orient the image correctly. The bracket may need to be attached upside down to achieve the desired angle. An optional pendant mount kit (sold separately) may make the installation cleaner. For best results, ensure the mounting surface can support the camera's weight and route the PoE cable properly.

For the PoE NVR S4, I couldn't find specific information about the cable length directly related to this product. For some other eufy camera kits, there are cases where cables like a 10-meter (33 ft) extension power cable are included in certain regional kits. Additionally, it is possible to extend cables, in some cases, up to 30 meters (98 ft) using compatible extensions.

The eufy PoE NVR S4 does not require any monthly subscription fees. It offers features such as local storage and smart functionalities without any hidden costs.

The eufy solar cameras, such as the SoloCam series, are not explicitly mentioned as compatible with the PoE NVR S4 system. The PoE NVR S4 system likely supports cameras designed for its PoE technology, while many eufy solar cameras are typically wireless and standalone or work with eufy-specific systems. If you'd like more details or confirmation about specific camera compatibility, it might be best to ensure the cameras are listed as supported accessories for the PoE NVR S4.
