The Vivotek FD9171-HT is a professional IP dome camera featuring a recording resolution of 2048 x 1536 at up to 30 frames per second. The Vivotek FD9171-HT professional IP dome camera features a 3 Megapixel Progressive CMOS image sensor together with a 3 ~ 9mm Varifocal Lens to provide a 41° ~ 86° horizontal angle of view.

The built-in infrared illuminators have an effective range of 30 meters / 90 feet and allow the camera to continue recording in low or no light environments. The Smart IR technology used on this camera prevents the image from whiting out by increasing or decreasing the IR intensity as objects move in front of the camera. To provide more clear images, the 3D Digital Noise Reduction helps to reduce the graininess of the image, this is especially useful when the camera is in black and white mode.

The all new H.265 video compression allows the camera to use less storage capacity while recording, in addition, the new compression also allows the camera to use less bandwidth when viewed remotely. When paired with the Smart Stream II technology, the H.265 video compression has been shown to reduce both storage, and bandwidth consumption by as much as 80% over H.264.

The WDR Pro Enhancement feature allows the camera to provide highly detailed image quality in environments with ultra bright or dark back lighting. It works by combining the darkest part of the image with the brightest part to create one balanced image. The PIR Motion Sensor on the camera captures motion by detecting the energy given off by an object, rather than being triggered by anything movement like traditional cameras. This allows the camera to reduce the amount of false alarms caused by moving trees or bushes.

The tri axis mechanical design allows the camera to be mounted to either a wall or ceiling with ease. A few more features of the FD9171-HT include POE 802.3AT compliance, a Removable IR Cut Filter and a Built-in Micro SD / SDHC / SDXC card slot for local storage recording.
