Specs
Can you add a wireless eufy camera to this set up?
Answered by Eufy TeamNo, you cannot add a wireless eufy camera directly to the eufy 4K NVR S4 Max. This NVR system is designed exclusively for PoE wired cameras. Wireless eufy cameras (such as SoloCams or eufyCams) require a HomeBase (sold separately) for connection and recording. While both sets of cameras can be viewed together in the eufy Security app, their recording and management remain separate.
Can these cameras be mounted under the soffit instead of to a wall?
Answered by Eufy TeamYes, the camera you referred to can be mounted under a soffit or on any horizontal surface like a ceiling using an appropriate outdoor mount. If you are working with this type of installation, ensure you use the correct mounting hardware to securely attach the camera to the chosen surface.
What are the dimensions of the NVR for this system? LxWxH
Answered by Eufy TeamThe dimensions of the eufy 4K NVR S4 Max unit are: 14.96 x 12.60 x 2.17 inches (380 x 320 x 55 mm)
How much is the 4TB and 8TB drive?
Answered by Eufy TeamIt does not list prices for separate 4TB or 8TB hard drives. To find out the cost for higher-capacity drives for this specific NVR, you have a few options: Check the Official Eufy Site: Visit the product page for the S4 Max on eufy.com or Anker's website. They often list compatible hard drives and their prices as optional accessories. Contact Eufy Support: They can provide the most accurate information on compatible drive models (brand, type) and their official pricing. Check Retailers: Look at the product listing on major retailers like Amazon, Best Buy, or B&H Photo. They sometimes sell the NVR bundled with larger drives or list compatible upgrades in the "Frequently bought together" section.
Do you offer a doorbell camera for this system?
Answered by Eufy Teameufy does offer doorbell cameras such as the eufy 1080P Wired Doorbell and the eufy 2K Wired Doorbell, which could be used in a comprehensive security setup. These doorbells feature wired setups, practical video resolutions (1080P and 2K respectively), HDR capabilities, two-way audio, and other advanced features such as smart human detection and real-time alerts. However, these doorbell cameras are not explicitly listed as being compatible with the eufy 4K NVR S4 Max system (PoE Wired, 24/7 Recording, TripleLens BulletPTZ). Compatibility between specific eufy doorbell cameras and the 4K NVR S4 Max system is not clearly established. If you are considering integrating a doorbell camera with the eufy 4K NVR S4 Max system, you may need to confirm whether the systems support each other via the eufySecurity app or require additional setup. If you are looking for standalone doorbell camera options, the above options are worth considering.
