- Note that almost all entities, including motion/ai detection and the camera streams, will be unavailable when privacy mode is turned ON. Check the history of the **Privacy mode** entity to see if this is causing the issues.
- Setting a static IP address for Reolink cameras/NVRs in your router is advisable to prevent (temporal) connectivity issues when the IP address changes.
- Do not set a static IP in the Reolink device itself, but leave the **Connection Type** on **DHCP** under **Settings** > **Network** > **Network Information** > **Set Up**. If you set it to **static** on the Reolink device itself, this is known to cause incorrect DHCP requests on the network. The incorrect DHCP request causes Home Assistant to use the wrong IP address for the camera, resulting in connection issues. The issue originates from the Reolink firmware, which keeps sending DCHP requests even when you set a static IP address in the Reolink device.

The issue originates from the Reolink firmware, which keeps sending DHCP requests even when you set a static IP address in the Reolink device.
- Reolink cameras can support a limited amount of simultaneous connections. Therefore using third-party software like Frigate, Blue Iris, or Scrypted, or using the ONVIF integration at the same time can cause the camera to drop connections. This results in short unavailabilities of the Reolink entities in Home Assistant. Especially when the connections are coming from the same device (IP) where Home Assistant is running, the Reolink cameras can get confused, dropping one connection in favor of the other originating from the same host IP. If you experience disconnections/unavailabilities of the entities, please first temporarily shut down the other connections (like Frigate) to diagnose if that is the problem. If that is indeed the problem, you could try moving the third-party software to a different host (IP address) since that is known to solve the problem most of the time. You could also try switching the protocol to FLV on Home Assistant and/or the third-party software, as that is known to be less resource-intensive on the camera.
- If the Reolink entities go to unavailable for short periods, the camera may be overloaded with requests resulting in short connection drops. To resolve this, first, check if the integration is using `ONVIF push` instead of `ONVIF long polling` (resource intensive) or `Fast polling` (very resource intensive), see the [Reducing latency of motion events](#reducing-latency-of-motion-events) section. Moreover, try switching to the <abbr title="flash video">FLV</abbr> streaming protocol which is the least resource-intensive for the camera, see the [options](#options) section.
