Advantages

The Reolink Argus Series B440 combines high-resolution 4K imaging and motorised pan & tilt movement to reduce blind spots and cover wider areas without additional cameras. Wireless connectivity simplifies installation where Ethernet is not available, and battery operation allows flexible placement both indoors and outdoors. Built-in intelligent detection reduces false alerts by distinguishing people, vehicles and animals, while color night vision improves detail in low light compared with standard infrared‑only systems.
