4K PoE Bullet Camera with Audio

The Avalonix IPC4K15 is an outdoor 4K PoE bullet camera with an 8MP image sensor, built-in microphone, Starlight low-light capability, and advanced event detection features that go beyond basic motion alerts. Unlike many ordinary IP cameras that only alert when pixels change, this Avalonix Premium Series camera can use Smart Motion Detection for human and vehicle filtering or IVS rules such as tripwire and intrusion detection for more precise event control.

The real advantage of the IPC4K15 is how it handles motion events. Smart Motion Detection, also called SMD, helps filter motion alerts based on whether the event was triggered by a person or vehicle when used with compatible Avalonix equipment. For more controlled detection areas, the camera can also use IVS rules such as tripwire and intrusion detection. Multiple tripwire and intrusion rules can be created on one Avalonix Premium Series camera, allowing different lines or zones to be monitored from the same camera view.

This makes the camera useful for driveways, entrances, storefronts, gates, loading areas, garages, side yards, and property edges where you want more than a simple motion box. A user can set up SMD for easier human and vehicle filtering, or use tripwire and intrusion rules when they need alerts from specific paths, entry points, or zones. For example, one rule can watch a driveway entrance while another watches a door or walkway in the same camera view.

This 4K security camera records 3840 x 2160 Ultra HD video, giving you a large image size for digital zoom during live view or playback. The camera uses a 3.6mm fixed lens with an 88 degree field of view for balanced coverage that is wide enough for general surveillance while still preserving useful detail. Source data lists up to 45ft of facial clarity in suitable daylight conditions, making it a good fit for areas where a clear view of people, vehicles, and activity matters.

For installations where wider scene coverage is more important than smart human and vehicle event filtering, a 2.8mm version is also available with a wider 105 degree field of view. The 3.6mm IPC4K15 version on this page is the better choice when you want SMD human and vehicle filtering, while the 2.8mm version is useful when you want to see more of the surrounding area from one camera position.

The built-in microphone provides one-way audio recording when audio recording is enabled and allowed by local laws. Sound detection is also supported, giving the camera another event option beyond video-based motion detection. This is not a two-way talk camera because it does not have a built-in speaker, but it is a good choice when you want one of our security cameras with audio for professional wired PoE recording.

Be sure to watch the video sample below to see how well the camera performs and the amount of facial detail it offers at distance.

This outdoor bullet camera comes standard with a 3.6mm lens that provides an 88 degree field of view and a Super IR LED for black-and-white night vision up to 100ft in darkness. With an IP67 weather resistant metal housing, it works for indoor or outdoor surveillance, property monitoring, and supported network viewing applications. The camera's 4K video resolution is supported by image features like True WDR, 3DNR, BLC, HLC, and Smart IR to help balance difficult lighting conditions.

Smart Motion Detection and IVS Rules

Many cameras offer simple motion detection, but basic motion detection can trigger from rain, insects, shadows, headlights, leaves, or other movement that does not matter. The IPC4K15 gives you more control by supporting Smart Motion Detection and IVS video analytics. SMD is useful when you want the camera or compatible Avalonix NVR to help filter motion events for human and vehicle activity. The video on our Smart Motion Detection guide also shows how Quick Search can be used to find human and vehicle events faster during playback.

IVS rules are useful when you want to define specific lines or areas in the camera view. Tripwire detection can be used to trigger an event when a person or vehicle crosses a virtual line. Intrusion detection can be used to monitor a defined area and trigger when a person or vehicle enters or remains inside that zone. Multiple tripwire and intrusion rules can be set on one Avalonix Premium Series camera, which is useful when one camera is covering more than one important path or entry point.

For best compatibility and easiest setup, we recommend using the camera with a compatible Avalonix NVR. The NVR allows centralized recording, playback, alerts, and event management for a complete system. The camera can also be used as a standalone IP camera with optional microSD storage, making it useful for single-camera installations where a full recorder is not needed.

Professional PoE Camera vs Consumer Home Cameras

Recording with MicroSD or NVR

The IPC4K15 can be used as a standalone camera or as part of a larger security camera system. For standalone use, the camera supports optional microSD storage up to 256GB, allowing local recording inside the camera. This is useful for a single entrance, driveway, gate, or outbuilding where you want a professional camera without installing a full NVR. You can learn more about this type of setup in our guide on using a security camera as a standalone camera.

For multi-camera systems, an Avalonix NVR is the better choice. The NVR provides centralized storage, easier playback, larger hard drive options, and a more complete way to manage alerts and recordings. If you are building a complete 4K security camera system, use one of our PoE NVRs for plug-and-play compatibility without needing advanced network configuration.

This camera uses PoE, which sends power and data over one network cable when connected to a compatible PoE switch, PoE injector, or PoE NVR. For a deeper explanation of how wired PoE camera installations work, see our PoE IP camera setup guide.

The camera is also ONVIF compatible for supported third-party recorders and software. ONVIF is useful for basic video compatibility, but smart analytics such as SMD human and vehicle filtering, tripwire, intrusion, and sound detection may require compatible Avalonix recording equipment.

If you're using just one camera as a standalone device, you can power it with a PoE injector, PoE switch, or 12V DC power adaptor. Since this is an IP camera, it can be viewed directly from your computer using our free PC/Mac viewing software or a web browser, mobile phone, or tablet device. Our Windows/Mac camera monitoring software is compatible with the equipment we sell and is available for free to view video.

The camera's video streams are adjustable for saving storage space, reducing viewing bandwidth, or streaming to the phone app.

Be sure to also consider the dome version of this camera which comes with 100ft of night vision, you can find it here: 4K IP Dome Camera.
