Resolution and Night Vision Comparison
Video Resolution
The Lorex V3 4K PoE Bullet Camera captures 4K (8MP) video, offering higher detail for large areas. The Lorex U3 2K+ PoE Bullet Camera records at 2K+ resolution. Higher resolution means you can zoom in on footage to identify faces or license plates more clearly. If you need maximum sharpness for wide coverage, the V3 provides the advantage. The U3 delivers clear views but with less pixel density than the 4K model. Choose based on how much detail you require in your recordings.
Night Vision Technology
Both cameras feature color night vision, but they use different lighting to achieve it. The V3 model uses a built-in spotlight to deliver full-color video in low light. The U3 model relies on vivid color night vision technology without mentioning a spotlight. The V3 gives you an active deterrent option with its white LED lights that activate with motion. The U3 uses high-intensity red and blue deterrence lights instead. Your choice depends on whether you prefer white light for identification or colored lights for visible deterrence.
AI Detection Features
AI detection helps reduce false alerts by focusing on relevant activity. The V3 camera detects people and vehicles to deliver reliable notifications. The U3 camera recognizes faces and identifies people and vehicles, providing key alerts. The U3 adds face recognition, which can be useful for distinguishing known individuals. The V3 focuses on general person and vehicle detection. Both systems aim to keep your security responsive and focused on important events. You get smart alerts with either model, tailored to your specific monitoring needs.
Audio and Communication
Audio features differ significantly between these two PoE bullet cameras. The V3 includes a built-in microphone and speaker for real-time 2-Way Talk through the app. It also supports optional pre-recorded quick response messages. The U3 offers listen-in audio, allowing you to hear what is happening in real time. It does not mention two-way talk capability. If you need to speak to visitors or intruders, the V3 is the better choice. The U3 is suitable if you only need to monitor audio evidence.
Physical Size and Mounting
Size affects how discreet or prominent your camera appears. The V3 measures 6.7 inches in width, 3.9 inches in height, and 3.9 inches in length. The U3 is smaller, measuring 4.07 inches in width, 3.24 inches in height, and 4.07 inches in length. The U3 is described as a small size with a lightweight bracket for easy mounting. Its tool-free attachment simplifies installation. The V3 is larger and may be more visible. If you prefer a compact profile, the U3 has the advantage in physical dimensions.

The Lorex V3 4K PoE Bullet Camera includes a built-in microphone and speaker for real-time 2-Way Talk through the Lorex mobile app. You can send optional pre-recorded quick response messages for instant interaction.
