4 MP outdoor dome camera

The AVI-8 4.0C-H5A-DO1-IR is a 4 MP outdoor dome camera designed for surface mounting. It uses a 1/1.8" CMOS sensor and a varifocal lens covering 3.3 to 9 mm. Video is encoded with H.264 HDSM Smart Codec compression. The unit is supplied new.

Suited for fixed outdoor positions needing

This camera suits installers who need a single outdoor dome with adjustable focal length for entryways, car parks or building perimeters. It is not for buyers who require a bullet form factor, a panoramic field of view or built-in infrared illumination beyond the standard specification.

3.3 to 9 mm varifocal lens sets the field of view

The 3.3 to 9 mm lens range determines how wide or narrow the captured scene will be. Choose this model when the installation distance and desired coverage match that focal span.

Questions about this item

How is the 3.3-9 mm varifocal lens adjusted during surface-mount installation?

Loosen the lens ring, aim at a live view on a monitor, zoom to the desired field of view, then tighten the ring before sealing the dome — skipping the live-view step leaves the focus soft at the edges.

Which component will need replacement first in an outdoor environment?

The IR illuminator LEDs behind the dome degrade after several seasons of night use, reducing low-light range before the 1/1.8" CMOS sensor shows any wear.

At what point does H.264 HDSM Smart Codec compression hit its practical limit during continuous recording?

Sustained high-motion scenes push the bitrate to the codec ceiling, forcing the camera to drop frames or increase quantization, which appears first as blocky artefacts on moving objects.
