Reolink Argus 4 Pro 4K 180° network camera

180° 4K panorama for wireless outdoor security

The Reolink Argus 4 Pro is a battery-powered network camera that stitches dual 8MP lenses into a seamless 180° field of view at 5120 x 1440 resolution. It targets homeowners who need wide-area coverage without running cables, offering ONVIF compatibility for integration with existing NVR systems. The wireless design uses dual-band 2.4 / 5.0 GHz connectivity for flexible placement around the property.

Sustained colour night vision without IR drain

ColorX technology pairs an F/1.0 aperture with a 1/1.8" CMOS sensor to deliver full-colour footage in darkness, eliminating the need for infrared LEDs or spotlights during night hours. This approach saves roughly 30% standby power compared with conventional IR cameras, extending the interval between charges. Dual PIR sensors spanning 180° feed the AI detection engine, reducing false alerts while maintaining constant vigilance across the entire panorama.

Wi-Fi 6 ceiling and local storage limits

The IEEE 802.11ac radio provides the physical link, while Wi-Fi 6 support improves throughput efficiency for 4K streaming when the router and signal conditions allow. Real-world bandwidth will vary with distance, obstacles and spectrum congestion, so sustained 4K bitrates are not guaranteed in every installation. Local recording relies on a microSD card up to 128GB, which caps continuous retention before overwrite occurs.
