Choosing between Wyze Cam v4 and Wyze Cam v3 starts with the job you want the camera to do. Both are compact, powered Wi-Fi cameras with Wyze app control and a microSD slot. The meaningful differences are resolution, built-in lighting and how confidently you can plan the installation.
Video and night-time viewing
Wyze specifies 2.5K QHD video for Cam v4 and 1080p for Cam v3. Higher resolution can be useful when you need more detail in a fixed view, but image quality also depends on lighting, placement and the network. Both models offer color night vision; v4 adds a built-in spotlight. Neither number alone guarantees that a distant face or license plate will be readable.
The placement question matters more than a spec sheet
Wyze markets both products as indoor/outdoor cameras. However, the latest certification evidence held for the specific WYZEC4 model sold here does not verify water resistance: its current CB report records IPX0 and removes the older IP65 marking. For this v4 listing, keep the camera protected from rain and moisture and do not treat older IP65 claims as confirmed. Wyze's v3 technical specifications list IP65 for v3. For any outdoor installation, also verify the power adapter and cable arrangement rather than assuming the included indoor power supply is suitable.
Recording and ongoing costs
Both cameras support local recording with a compatible microSD card. Check card capacity and formatting against the exact model's current support page, and check whether the card is included in your selected bundle. Wyze's cloud plans add different features; subscriptions and availability can vary, so review the current terms before ordering.
Which one should you choose?
- Pick v4 for an indoor, powered fixed view when 2.5K video and a built-in spotlight matter most.
- Pick v3 if 1080p meets your needs and the model-specific weather-resistance documentation fits your intended placement.
- Pick neither yet if you cannot provide stable power, compatible Wi-Fi or a suitable installation location.
