Product information

Description

The Reolink Argus Series B350 4K is a wireless outdoor IP security camera with battery power, designed for both indoor and outdoor monitoring. It delivers 8MP 4K resolution and a 105° horizontal / 55° vertical field of view to capture wide, detailed footage. The camera offers color night vision up to 10 m, dual-band 2.4/5 GHz Wi‑Fi for stable connections, person/vehicle/animal detection with push notifications or email alerts, two-way audio, siren and spotlight deterrents, and flexible storage via up to 128 GB SD card or cloud.

Advantages

Dual-band Wi‑Fi improves connection stability and live-view smoothness. Smart detection discriminates people, vehicles and animals to reduce false alarms. Two-way audio and dual warning (siren + spotlight) increase control over events at the scene. Battery-powered and wireless design simplifies installation and allows both indoor and outdoor placement; IP65 rating protects against dust and rain.

How to use

Install the Reolink Argus B350 by mounting it on a wall or placing it in a suitable outdoor or indoor location, ensuring the camera has a clear view of the area to monitor. Power the camera with its battery and connect it to your 2.4/5 GHz Wi‑Fi network using the Reolink App or Client. Configure detection zones and notification preferences in the app, insert a microSD card if local recording is needed (max 128 GB) or enable cloud storage. Use the app or PC client to view live feed, replay recordings, and operate two‑way audio or activate the siren/spotlight when required.

Design

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
