CX820

The Reolink CX820 is a 4K 8MP PoE security camera designed for high-quality outdoor surveillance. It features ColorX night vision technology, which allows it to capture full-color images in low-light conditions without relying on infrared black-and-white night vision.

The main difference between the Reolink CX810 and CX820 is their design. The CX810 is a bullet-style PoE camera, while the CX820 is a turret-style camera. Both models offer the same core performance, including 4K 8MP resolution and ColorX night vision, but differ mainly in form factor and installation appearance.

No, the Reolink CX820 does not have infrared (IR) night vision. Instead, it uses ColorX low-light technology with a built-in warm spotlight to produce full-color images at night. This means it relies on ambient light and its spotlight rather than traditional IR LEDs for black-and-white night vision.

The Reolink CX820 uses ColorX night vision, a low-light imaging technology that allows the camera to capture full-color video even at night without relying on infrared black-and-white footage.

Instead of switching to traditional IR night vision, it uses a larger sensor and enhanced light sensitivity to maintain color details in dark environments, such as street lighting or dim outdoor areas. This helps improve visibility of important details like clothing, objects, and vehicle colors in nighttime recordings.

To reset the Reolink CX820, locate the reset button on the camera body (usually near the microSD card slot or cable junction). Make sure the camera is powered on, then press and hold the reset button for about 10–15 seconds until you hear a voice prompt or see the device restart.

After the reset, the camera will return to factory settings and you will need to re-add it in the Reolink app to set up Wi-Fi, password, and other preferences again.
