If you are recording a meeting with a landlord who will not put anything in writing, sitting through a disciplinary meeting at work, or documenting a job a tradesperson says he finished, the useful question is not which pen camera...

A wearable camera points where your body points, and that is the whole difference between this category and every other camera we sell. A camera on a shelf has a view you choose once and it stays chosen. A camera...

Everything else in this shop is a camera hidden in an object somebody else chose. This is the range where you choose the object. You buy a module, a lens on a cable, a power source and a storage plan,...

There are four ways to find a hidden device, and each one is blind to what the others catch. Radio scanning finds things that transmit. Optical scanning finds lenses whether or not they are powered. Magnetic scanning finds trackers stuck...

Before you compare a single specification, know where you are allowed to use one of these. Since 1 June 2024 the Department of Conservation permits hand-held thermal devices on public conservation land during daylight hours. Firearm-mounted thermal is still prohibited,...

Spy camera glasses are the only wearable that needs no aiming at all. Every other worn camera has to be pointed, and a chest-mounted lens swings off target every time you turn your head. Glasses point exactly where you are...

A hidden camera is chosen by the object, not by the camera. Resolution is the last thing to compare and the first thing everybody looks at. Two cameras with the same sensor will give completely different results depending on what...

A WiFi security camera is only as good as the signal at the spot you want to mount it, and that spot is almost always the worst-covered corner of the property. The back fence. The far side of the garage....

A solar security camera does not fail in January. It fails in July, and by then it has usually been installed for six months and nobody is watching the battery graph any more. That is the whole problem with this...

These are self-monitored alarm systems, and that is the most important thing to understand before you buy one. When a sensor triggers, a siren sounds and your phone gets an alert. Nobody is dispatched. There is no control room, no...

Four separate cameras is not a security system. It is four apps, four cards, four batteries and four things to remember. A system is what you buy when the property has more places worth watching than you can keep in...

A voice recorder is bought on one number, and it is almost never the one on the front of the box. Not memory, not battery size, not recording hours. It is standby time, because most of these devices spend the...

A body camera is the one recording device in this shop that works better when everybody can see it. It is worn openly, on the chest, and the deterrent effect of a visible camera is a large part of what...

Two decisions cover almost everything: how many lenses you need, and whether the camera keeps recording when the engine is off. Front and rear coverage answers the crash. Parking mode answers everything that happens while you are not in the...

A 4G security camera needs no WiFi and no mains power, which is the entire point of buying one. It carries its own SIM, so it works on a boundary fence, a construction site, a bach with no connection, or...

A trail camera is the only camera you buy expecting to walk away from it for months. Everything about choosing one follows from that: how it gets power, how the footage reaches you, and whether it is still there when...

Almost every GPS tracker sold does the same thing. What separates them is how they get power, and that single question decides which of the fifty-seven models here you should be looking at. A tracker wired into a vehicle never...
