Quick Answer

Choose the eufy Wall Light Cam S4 if you want radar-based motion detection that cuts false alarms, or the Floodlight Camera E340 if you need 360° coverage and 24/7 recording.

Radar vs Dual-Lens: The Core Difference

The Wall Light Cam S4 uses 60 GHz mmWave radar with a 120° ultra-wide view and 12 m range. This technology is designed to ignore pets and swaying plants, so you get fewer false triggers. The Floodlight Camera E340, on the other hand, relies on dual-lens technology that combines two camera views for a seamless 360° perspective. This gives you complete coverage around the camera but may require more careful positioning to avoid blind spots from moving objects.

Trade-offs at a Glance

  • Motion Detection: Wall Light Cam S4: Radar-based detection (60 GHz mmWave) with 120° view. Floodlight E340: Standard motion sensor.
  • Camera Coverage: Wall Light Cam S4: 4K / 8 MP fixed view. Floodlight E340: 360° coverage via dual lenses.
  • Recording: Wall Light Cam S4: Event-based recording (requires HomeBase S380 for continuous). Floodlight E340: 24/7 recording with local microSD card (up to 128 GB) or HomeBase S380. If 24/7 recording is essential, the Floodlight E340 is the straightforward choice.
  • Deterrence: Both: Multi-level light and siren warnings. Wall Light Cam S4 adds proactive intruder detection via radar.
