Advantages

Built-in motion spotlights provide active lighting to improve detection and color imaging in low light conditions. H.264 compression reduces bandwidth and storage requirements. The IP65-rated housing enables outdoor use under rain and dust exposure, and local microSD storage up to 256 GB offers straightforward on-site recording.

Suitable for

• Residential outdoor monitoring of entrances, driveways and yards
• Small business premises requiring remote PTZ control and active lighting

How to use

Install the camera at a suitable outdoor location using weatherproof mounting hardware and ensure it has reliable WiFi coverage. Insert a compatible microSD card (up to 256 GB) for local recording if required. Use the Reolink mobile or desktop app to connect the camera to your network, configure PTZ presets, set motion detection zones and enable motion spotlight behavior. Adjust the varifocal lens to set the desired focal length between 2.8 mm and 8 mm for the preferred field of view. Use live view and playback features in the app to review recorded events and control pan/tilt/zoom remotely.

Usage recommendations

For best results, mount the camera at a stable height with a clear line of sight to the monitored area, avoid pointing the lens directly at strong light sources, and test motion detection sensitivity and spotlight settings to reduce false alerts. Regularly check firmware updates through the Reolink app and back up important recordings from the microSD card.
