Wyze Cam v4 Review
A very cheap camera with a genuinely useful local-storage option. The trade-offs are in the app and the subscription, not the hardware.
Wyze built its reputation on cameras that cost far less than the competition and mostly delivered. The Cam v4 continues that pattern: the sensor and night vision are better than the price suggests, and the honest limitation is that several of the features people expect from a security camera sit behind the Cam Plus subscription.
What makes this camera interesting is that it does not force the subscription on you — a microSD card gives you local recording, which most budget cameras in this class do not offer at all. That is the detail worth understanding before you buy.
What the Cam v4 is
An indoor and outdoor-rated camera with a 2.5K sensor, colour night vision, a built-in spotlight, two-way audio and motion detection. It supports microSD card recording locally, and works with Alexa and Google Home for viewing on a smart display.
It is designed to be mounted or placed on a flat surface, and unlike many budget cameras it is rated for outdoor use — which makes it unusually flexible for the money, provided it has power and Wi-Fi coverage.
Local recording is the headline feature
A microSD card turns this from a live monitor into a camera with actual recorded history, with no ongoing cost. You lose some of the smarter alert types, but you keep the footage, which for most people is the point of owning a camera at all.
Two practical notes. Cards wear out — continuous recording writes constantly, and a card rated for high-endurance use lasts far longer than a generic one. And check the maximum supported card size in the current specification, because it has changed between Wyze models.
If you use a card, format it in the camera through the app rather than on a computer. Cameras are fussy about filesystems, and an incorrectly formatted card is the most common reason local recording silently fails.
What Cam Plus adds, and whether you need it
The subscription layer provides cloud recording, richer detection that distinguishes people, packages, pets and vehicles, and longer event clips. Without it, you get motion alerts and local recording rather than cloud history and smart classification.
The decision is straightforward. If you want the camera to tell you specifically that a person walked up the drive, you want the subscription. If you want a record of what happened that you can review yourself, local storage does the job at no monthly cost.
Worth knowing: notification quality without smart detection is the weak point. Motion alerts without classification fire on moving shadows and passing cars, and people who buy purely on price often end up paying for the subscription anyway to stop the noise.
Image quality and night vision
2.5K is a genuine step up from 1080p for detail — reading a number plate at the edge of frame, or identifying a face at a doorway. For a camera at this price it is the strongest argument in its favour.
Colour night vision depends on the built-in spotlight, which means it illuminates what it is watching. That is useful in a garden or a driveway and undesirable in a room where someone is sleeping. In near-darkness without the spotlight, expect infrared-style monochrome rather than colour.
Field of view is wide enough for a doorway or a corner, but this is not a camera for covering a large open area in detail. Placement matters more than specification here — a well-placed budget camera beats a badly placed expensive one.
App, Wi-Fi and reliability
Budget cameras live or die on their app, and this is where the trade-off is most visible. Wyze's app has accumulated a lot of features over the years, and the ones you use daily are not always the ones in front of you.
Wi-Fi is the other consideration. These cameras connect on 2.4 GHz, and at the edge of coverage they drop events. If the camera is going outdoors, check signal strength at the mounting position on your phone before you drill anything — a camera that works on the windowsill may not work on the wall.
Who it suits
This suits anyone who wants several cameras without a large outlay: a back garden, a side gate, a garage, a spare room. The ability to run without a subscription makes it unusually good value for people who want coverage in low-stakes places.
It is a weaker fit if you want a polished, tightly integrated ecosystem, or if you need the camera to reliably identify people and packages without any monthly cost. In that case, a camera with a stronger detection system and a plan included is the more honest comparison, even if the sticker price is higher.

Frequently asked questions
Does the Wyze Cam v4 record without a subscription?
Yes, to a microSD card installed in the camera. You get recorded footage without ongoing cost, but not the person, pet, package and vehicle detection that Cam Plus provides.
Can I use it outdoors?
It is rated for outdoor use, but it needs power and adequate 2.4 GHz Wi-Fi at the mounting position. Test signal strength where you intend to mount it before installing.
What size microSD card does it take?
Check the current specification for the model you buy, as the supported maximum has changed across Wyze generations. A high-endurance card is worth the small premium for continuous recording.
