Mini Spy Cameras
How to choose a mini spy camera
Small bodies mean trade-offs
A smaller camera holds a smaller battery. Mini cameras are excellent in motion triggered standby, waiting days or weeks and recording only when something happens, but continuous recording drains them in hours. For constant recording, choose a model that can stay plugged in or a mains powered hidden camera instead.
WiFi, 4G or card only
WiFi models let you watch live and get motion alerts on your phone. Where there is no WiFi, a shed, a gate, a bach, a 4G model with a SIM slot is the only option that reaches you. Card only models are the simplest: no network, no app, and you review the footage when you collect the camera.

Common questions
How long does the battery last?
Hours in continuous recording, days or weeks in motion triggered standby. Models with a USB input can stay plugged in and run without limit.
Can it record in the dark?
Most have infrared night vision, which records in full darkness without a visible light. The listing gives the range.
Do I need WiFi?
Only for live viewing and alerts. Card only models need nothing, and 4G models bring their own connection on a SIM.
Is it legal to use a hidden camera in New Zealand? NZ law
On your own property, yes, with limits. The Crimes Act 1961 makes it an offence, with up to three years in prison, to record anyone where they would expect privacy while undressed, showering, using a toilet or in an intimate situation (sections 216G to 216J), so bathrooms, bedrooms and changing areas are off limits. If the camera records sound, the same rule as a voice recorder applies: you can only capture conversations you are part of (section 216B), so switch audio off for anything that records while you are away. Since 26 May 2026, repeatedly recording or tracking a particular person in a way you know is likely to cause fear or distress is stalking under the Crimes Act (sections 216O to 216Q), with up to five years. A business using cameras must follow the Privacy Act 2020: a clear purpose, telling people they are recorded, footage kept secure and no longer than needed, and access for anyone who asks for footage of themselves.
