- Motion alerts can be slow
The Wyze Cam v3 is an affordable camera with built-in motion detection. It records 1080p video with color night vision and is IP65 rated for outdoor use. Owners find it a great value for monitoring a porch or backyard, though motion alerts sometimes lag by a few seconds.

What to check before buying a motion sensor under £150
Consider the detection range and field of view. A wider angle covers more area but may increase false triggers. For outdoor use, look for an IP65 or higher weather resistance rating.
Check the power source. Wired sensors are more reliable but require installation. Battery-powered sensors are easier to place but need periodic battery changes. Also, ensure the sensor works with your smart home system, such as Alexa, Google Home, or Apple HomeKit.
Mistakes to avoid when choosing a motion sensor
Do not ignore the field of view. A sensor with a narrow angle may miss movement at the edges of the room. Also, avoid placing sensors near heat sources or vents, as this can cause false alarms.
Do not assume all sensors are weatherproof. Many indoor sensors are not rated for outdoor use. Always check the IP rating before installing outside. Finally, verify compatibility with your existing alarm or smart home hub to avoid extra costs.
