Spy Cams: What to Look For
While spy cams are rather simple devices with limited features, there are certain aspects that comprise a quality, durable camera. We identified the following criteria as key factors to consider when searching for a top-notch pinhole camera.

Design
The best spy cams are those that boast an inconspicuous and portable design. With this in mind, we assessed the overall design – appearance, size and basic functionality – of each camera. We evaluated specific dimensions (depth, height and width), whether or not the camera had durable alloy housing, and what type of clips and mounting brackets were included to enable hands-free recording. We also looked for particular design features that enhanced convenience, such as VOX (or sound-activated) mode, webcam functionality and an audio capture feature.
Video/Image Output
Given their miniature size, they do not have the capability to deliver high-definition video; nor are they meant to. However, the cameras should be able to yield fairly clear video where movement and actions are distinguishable and the audio is mostly intelligible. Factors we assessed include video resolution, minimum lux rating, file format and frame rate – all determinants for how well it produces video. Some cams can also take still digital photos, so we included image resolution in our side-by-side comparison.
Memory
Memory capacity on any camera is vital; the more memory it offers, the more data the camera can store internally. All spy cams are equipped with a memory card, though they differ when it comes to the type and maximum capacity of the card. Furthermore, while some spy cams have built-in memory, others have card slots that can support compatible memory cards with additional storage. Generally speaking, first-rate spy cams are those that offer high memory capacity and have adequate store consumption (e.g. 30 minutes of footage per gigabyte).
Battery
Battery specifications are just as important as memory capacity. Since they are lightweight and powerful, Lithium-ion batteries are the most commonly-used battery type in self-contained cameras. In addition to battery type, we analyzed the approximate battery life (or how long a single charge lasts) of each spy pen pinhole camera. Simply put, a longer battery life translates to more continuous recording.
The best pinhole cameras encompass those that rank generally well in each of these categories. Among the standout spy cams in our lineup are the WINN MD90 Mini DV, the Global CCTV Security Mini DV LJ-DV811 and the Veho Muvi Atom.
