Third-party reviews

What we like about SJCAM A20

  • Long battery life due to the high-capacity 2650mAh battery.
  • Very cost-effective and budget-friendly choice compared to premium alternatives.
  • Includes helpful dual-stereo microphones with internal noise reduction software.
  • Features built-in infrared LEDs for improved visibility during night recording.
  • Comes with a slim body shape that fits snuggly and securely against the chest.
  • Equipped with functional gyro image stabilization for smoother capture.
  • IP65 waterproof and dustproof rating protects against rain and harsh working environments.

What we don't like about SJCAM A20

  • Video dynamic range is poor when capturing high-contrast scenes.
  • Low-light video recordings can sometimes look grainy or muddy despite the night vision.
  • The official smartphone companion app can be unreliable or difficult to pair.
  • Build quality feels mostly plastic and less rugged than premium action cameras.
  • Video resolution options are limited at higher framerates compared to modern sports cameras.

Verdict

The SJCAM A20 is a versatile wearable body and action camera featuring a Sony IMX335 sensor and Novatek NT96660 chipset, capable of recording 4K video at 24fps and capturing 16MP still photos. It is equipped with a 2.33-inch LCD touchscreen, a wide 166-degree 6G aspherical lens, and dual-microphone noise reduction for clear audio. Key pros include its multi-functional design suitable for law enforcement (body cam) or driving (dash cam), an impressive 2650mAh battery providing up to 8 hours of runtime, and a dedicated LED lamp for starlight night vision. However, notable cons include its IP65 rating which is only splash-proof rather than fully submersible without a case, and a relatively low frame rate for 4K video compared to high-end competitors.
