This article covers Ubiquiti UniFi Protect G4-Bullet カメラ.

Overview

The Ubiquiti UniFi Protect G4-Bullet (model UVC-G4-Bullet) is an outdoor security camera designed for the UniFi ecosystem. It captures 4MP video at 24 FPS and features built-in infrared LEDs for round-the-clock surveillance. The weatherproof enclosure protects against rain and dust, making it suitable for outdoor mounting.
Power is delivered via Power over Ethernet (PoE), eliminating the need for a separate power cable. A built-in microphone captures audio alongside video, and ONVIF support allows integration with third-party NVRs and software. This camera is a solid choice for users who want a reliable, wired IP camera with good image quality.

Connectivity & Compatibility

The G4-Bullet connects exclusively over wired Ethernet (PoE) — no Wi-Fi or Bluetooth. It complies with IEEE 802.3af PoE, so you need a PoE switch or injector. Video is streamed via RTSP, and the camera works with UniFi Protect apps or ONVIF-compatible clients. However, to unlock all features (motion detection, event recording, smart alerts), you must run UniFi Protect software on a compatible controller such as UniFi Cloud Key Gen2 Plus, UniFi NVR, or UniFi Dream Machine Pro.

Product Info

Released around 2020, the G4-Bullet remains a current product. It is priced at approximately ¥36,705 on Japanese online retailers, placing it in the mid-range outdoor PoE camera segment. The package includes the camera, mounting bracket, screws, and a cable gland. Warranty details are available on the manufacturer’s website. Market positioning: an entry-to-mid-level camera that integrates best within the UniFi ecosystem but also offers basic ONVIF compatibility for broader use.

Best Use Cases

  • UniFi Protect users expanding their system: If you already own a UniFi Cloud Key or Dream Machine, adding the G4-Bullet is straightforward. Setup is done through the UniFi app, and all recordings are managed centrally.
  • Homeowners needing outdoor surveillance: Ideal for monitoring driveways, backyards, or front entrances. The IR LEDs provide clear night vision, and the built-in mic captures ambient sounds.
  • Small business or retail security: Cost-effective and easy to deploy with PoE cabling. ONVIF support allows integration with existing surveillance setups, though full functionality requires UniFi Protect.
  • Users with existing PoE infrastructure: No extra power wiring needed — just run an Ethernet cable. If you lack PoE, you’ll need to purchase a PoE injector separately.
