• Hub requirement ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.5
  The S330 requires the HomeBase 3 hub to connect cameras, phones, and the network, which some reviewers see as an extra box and minor inconvenience even though the hub adds local storage, AI processing, and can be tucked unobtrusively on a shelf once the occasionally finicky first-time pairing is complete.

  The S330 delivers clean color night vision when its spotlight is active and high-contrast black-and-white footage otherwise, with good detail out to roughly 30 feet, although some reviewers note that out-of-the-box settings may default to black and white and that pet and animal detection at night is less reliable than daytime monitoring.
