Reolink CX810 vs CX820: Which 4K Color Night Vision Camera is Right for Your Home?

When it comes to home security, capturing clear, colorful footage at night can make all the difference. Reolink's CX series is designed to deliver vibrant 4K color video even in low-light conditions, eliminating the need for external floodlights. Two popular models in this lineup are the CX810 and the CX820. While they share the same core 4K color night vision technology, they have distinct differences that may make one a better fit for your property.

In this comparison, we'll break down the key features, performance, and use cases for the Reolink CX810 and CX820. By the end, you'll know exactly which camera belongs on your wall.

Design and Build Quality

The CX810 and CX820 share a similar bullet-style design, but there are subtle differences. The CX810 features a more traditional cylindrical shape with a separate antenna, while the CX820 has a sleeker, integrated design with a built-in antenna. Both cameras are weatherproof with an IP66 rating, ensuring they can withstand rain, snow, and dust. The CX820 is slightly more compact, making it easier to fit into tight spaces. Both models come with a mounting bracket and necessary hardware for easy installation.

Image Quality and Night Vision

Both cameras boast 4K resolution (3840x2160) and use a large f/1.0 aperture lens to capture more light. They also feature a built-in spotlight and IR LEDs for color night vision. However, the CX820 has a wider field of view at 110° diagonal compared to the CX810's 100° diagonal. This extra width can be beneficial for covering larger areas like driveways or backyards. The CX820 also includes a higher number of IR LEDs, providing slightly better illumination in complete darkness. In practice, both deliver crisp, colorful footage at night, but the CX820 offers a slight edge in coverage and low-light performance.

• CX810: 100° diagonal FOV, 4 IR LEDs
• CX820: 110° diagonal FOV, 6 IR LEDs

Smart Detection and Alerts

Both cameras support person, vehicle, and pet detection thanks to Reolink's AI technology. You can customize detection zones and receive instant push notifications. The CX820 adds an extra layer of intelligence with its built-in siren and two-way audio, allowing you to deter intruders or communicate with visitors. The CX810 also has two-way audio but lacks the siren. For those who want an audible deterrent, the CX820 is the clear choice.

Storage and Connectivity

Both cameras support local storage via microSD card (up to 256GB) and continuous recording to a Reolink NVR. They also work with Reolink's cloud storage service. Connectivity-wise, both are Wi-Fi (2.4/5 GHz) and Ethernet-capable, giving you flexible installation options. The CX820 includes Bluetooth for easier setup, while the CX810 relies on a standard wired connection. If you prefer a hassle-free wireless setup, the CX820's Bluetooth pairing is a nice convenience.

Which One Should You Choose?

The choice between the CX810 and CX820 ultimately comes down to your specific needs. If you want a slightly wider field of view, more IR LEDs, a built-in siren, and Bluetooth setup, the CX820 is worth the extra investment. It's ideal for covering larger outdoor areas where you need both color night vision and an audible alarm. On the other hand, if you're on a tighter budget or need a reliable 4K color camera without the extra bells and whistles, the CX810 delivers excellent performance at a lower price point. Both cameras are compatible with Reolink's ecosystem, including the Home Hub with Argus PT Ultra for centralized management.

Both the Reolink CX810 and CX820 are outstanding 4K color night vision cameras that bring vibrant, detailed footage to your home security. For those who want the best in class with extra features like a siren and wider FOV, the CX820 is the way to go.
