Alarm.com ADC-VC8498PA

The Alarm.com ADC-VC8498PA is a professional-grade outdoor PoE dome camera designed for installations that require both ultra-high resolution and flexible scene coverage. It records video at up to 3840 × 2160 resolution, delivering true 8MP (4K Ultra HD) clarity. This increased pixel density allows for improved identification of faces, objects, and activity, especially when digitally zooming into recorded footage.

Unlike the ADC-VC8498P-PVT, the fixed-lens model, the ADC-VC8498PA uses a varifocal lens that allows the field of view to be adjusted during installation. This gives installers the ability to widen coverage for large areas or tighten the view to focus on specific points of interest, such as doorways, gates, or drive lanes. Once adjusted, the lens remains fixed in place, providing consistent framing without ongoing maintenance.

The camera is powered using IEEE 802.3af Power over Ethernet (PoE), which delivers both power and data over a single Ethernet cable. This simplifies wiring and improves reliability compared to battery-powered or Wi-Fi-dependent cameras. For multi-camera deployments, the ADC-VC8498PA can be powered through a compatible PoE switch, allowing centralized power and network management.

At the imaging level, the ADC-VC8498PA uses a 1/1.8” SONY STARVIS 2 CMOS image sensor. This sensor is designed for enhanced low-light performance and helps preserve color and detail as lighting conditions deteriorate. The camera supports High Dynamic Range (HDR), which improves visibility in scenes with strong contrast, such as bright sunlight, shadows, or vehicle headlights. Integrated infrared night vision allows the camera to maintain visibility in complete darkness.

For installations that require external audio devices, Alarm.com offers the ADC-VACC-AO-015 audio breakout cable. This accessory is required to access the camera’s audio line-in and line-out connections, allowing support for external microphones and speakers on PRISM Series 8MP dome cameras.

The ADC-VC8498PA integrates directly into the Alarm.com platform and supports advanced motion-based event detection when paired with a compatible video service plan. These features help filter out unnecessary alerts and highlight meaningful activity. Alarm Grid explains these tools in detail here: What Are Alarm.com Video Analytics?.

Built for demanding environments, the ADC-VC8498PA features a rugged enclosure rated IP66 for dust and water resistance, IK10 for impact resistance, and NEMA 4X for added outdoor durability. This makes it suitable for commercial locations, exposed outdoor areas, and high-traffic residential installations.
