Does the RLC-510A need a PoE switch?

Yes. It is powered over Ethernet, so you need a PoE switch or injector, or a PoE NVR. A plain router port will not power it.

Can it record without a subscription?

Yes. It records to a microSD card and can feed a Reolink NVR or third-party software. No cloud plan is required.

Is it fully wireless?

No. It is a wired camera. It needs an Ethernet cable run to the camera, which also carries power.

Does it work with Google Home and Alexa?

Yes. You can ask a Google or Alexa display to show the live feed. Recording and settings are handled in the Reolink app.

What is the difference from the RLC-520A?

The 520A is a turret-style camera with a similar 5MP sensor and PoE setup. The 510A is a bullet body, which some owners prefer for aiming along a wall or fence.

What comes in the box?

One camera, mounting hardware, a waterproof cable connector and a quick start guide. A power adapter and Ethernet cable are not always included, so check before buying.
