Camera Mount Compatibility Guide: Nest, Eufy & Arlo

Missing a camera mount or replacing a damaged plate? Start with the exact device name and the part you need. A doorbell plate, magnetic camera mount and floodlight box adapter serve different purposes, even when the brand is the same.

Before choosing a replacement mount

  • Check the full model name and model number on your device or its original packaging.
  • Confirm whether it is a wired doorbell, battery doorbell, battery camera or floodlight camera.
  • Compare the mounting connection and product photos, then read the listing's compatibility and included-parts sections.
  • Check the selected option: a plate-only order may not include the same hardware as a mounting kit.

Mounting plates compatible with Nest Doorbell

Wired and battery doorbell plates are not interchangeable. For the wired 2nd- and 3rd-generation models listed in our catalog, choose the replacement mounting plate compatible with Nest Doorbell Wired. For the battery model, see the plate compatible with Nest Doorbell Battery, which includes a dock-recognition magnet. These listings do not include a doorbell.

Is Eufy SoloCam E30 the same as Floodlight E30?

No. Match the complete camera name, not just “E30” or “S330.” Our SoloCam and LTE replacement bracket lists compatibility with SoloCam S340, SoloCam E30, SoloCam E42 and 4G LTE Cam S330.

The separate bracket compatible with Eufy Floodlight cameras lists Floodlight E30 model T8426, E340 and S330/Floodlight Cam 2 Pro. It is not for SoloCam E30. Review that listing's installation, certification and temperature limitations before ordering.

Choosing a mount compatible with Nest Floodlight Camera

Compare the standard mounting kit and compact mounting kit if you need a replacement camera mount. The compact version has a smaller bezel.

If you need an adapter for an electrical box, compare the round-box adapter and double-gang box adapter. Check the specific Sigma box named in each listing. Mount Only and Mounting Kit have different contents; conduit, wiring and other installation supplies are not automatically included.

Does the Arlo back plate include a security mount?

No. The back plate compatible with the Arlo anti-theft mount includes the replacement PETG back plate and mounting hardware only. The security mount shown for reference is not included. Confirm your mount and camera against the listing before ordering.

Still unsure which part fits?

Use our contact page and send the full device model plus a clear photo of the mounting connection. Check fit before purchasing when your model or hardware differs from the listing.
