Reolink Argus Series B340 wire-free IP camera: 5MP video, 2.4/5GHz Wi-Fi, colour night vision with spotlights, person/vehicle/pet alerts, IP66 and microSD storage.

Suitable uses

Suitable for a garden, entrance or outdoor viewpoint where reducing fixed power wiring helps placement. Check Wi-Fi coverage, the intended recording mode and charging arrangements; solar accessories are included only where listed for this version.

Key features

Dual-band Wi-Fi: Choose 2.4GHz for better reach through walls, or 5GHz for a faster link when the router is closer.
Colour at night: Two spotlights let it record in colour after dark, and eight infrared LEDs give black-and-white night vision up to 10 m.
Person, vehicle and pet alerts: PIR sensing plus smart detection sorts events into person, vehicle or pet, and a detected motion can trigger the spotlights and siren.

For the difference between triggered clips and all-day footage, read battery CCTV missing the start: triggers and recording modes before checking detection coverage and recording settings.

Does it record around the clock?

No. Reolink lists triggered recording only, so it saves clips when motion is detected, plus time-lapse videos.

When it arrives: first setup and checks

Power up in an accessible position, charging battery models as instructed, and check package contents. Use the exact model's manufacturer instructions and app prompts to add it. Do not substitute another version's pairing or reset procedure.
Use this model's supported Wi-Fi band, Ethernet or base-station connection. Pair near the router where appropriate, then check signal at the intended position before fixing it in place.
Configure account/device security and viewing permissions using this model’s supported settings. Check date, time, notifications and framing.
Enable a supported card, NVR/hub or cloud recording method. Test recording, playback and storage location before permanent mounting. Live view does not mean recording is active. Battery models do not all support continuous recording.
