Product Identity

The Gyration CYBERVIEW 811B is an 8MP varifocal bullet network camera built for outdoor surveillance. It captures video at up to 3840x2160 resolution using a 1/2.8" CMOS sensor and supports Power over Ethernet for simplified cabling. Installers and system integrators deploy it where adjustable viewing angles and two-way audio are required. It is not suited for buyers who need a dome form factor or a camera without a micro SD slot.

Deciding Specification

The varifocal lens provides a horizontal angle of view ranging from 107.4° down to 29.2°, letting the installer narrow or widen the scene after mounting. Maximum frame rates reach 20fps at 8MP and 30fps at 5MP, 4MP or 1080p, with a sub stream available at 1080p, 720p or D1. Onboard storage accepts a micro SD card up to 256GB for local recording.

Installation Reality

PoE (IEEE 802.3af) or 12V DC power connects through a single cable run, and the bracket allows pan 0°–360°, tilt 0°–90° and rotate 0°–360° for precise aiming. The IR-cut filter switches automatically for night vision, while the shutter can be set from 1 to 1/100000s. Common issues include exceeding the 10.5W power budget on long PoE runs and forgetting to format the micro SD card before first use.

Questions about this item

What does 8MP at 20fps mean for recorded footage?

The camera records 3840x2160 video at up to 20 frames per second; higher frame rates of 30fps are available at 5MP, 4MP and 1080p resolutions.

How does PoE IEEE 802.3af power the unit in practice?

It delivers up to 10.5W over a single Ethernet cable, removing the need for a separate 12V DC supply and simplifying outdoor installation.

What mounting adjustment does the 360° pan and 90° tilt provide?

The bracket allows full horizontal rotation and vertical tilt up to 90°, so the bullet housing can be aimed at any angle on a wall or ceiling.
