Imou A1 4MP Indoor Camera Test: A Motor, Affordable and Efficient Surveillance Solution

Imou A1 4MP Indoor Camera Test: A Motor, Affordable and Efficient Surveillance Solution

The A1 4MP, as its name implies, is equipped with a 4 megapixel sensor. So it can shoot up to 2K and is accurate up to 2560 x 1440 pixels. This definition is referred to as “HD” within the application. Also known as the “SD” definition for those who choose local storage for the space available on the microSD card, to save at the expense of significant loss of quality.

The definition not only drops to 640 x 480 pixels, but is captured in Figure 16: 9; So it is stretched vertically. In short, staying in 2K is good. On the other hand, the Emou offers an HDR mode, which is useful in backlit situations, and its camera certainly provides infrared vision at night.

We decided to measure the A1 4MP Swiss’s C6W. For a little more money, the latter offers similar features and got better results in our tests.

Despite similar limitations, the A1 4MP fails to capture details as well as its signature competitor, the SUV, and the bright elements in the bright background stand out less due to the exposure settings favorable to high light. On the other hand, the dark areas are a little less blocked in Imo’s camera image. Overall, it provides the most satisfactory image quality for a surveillance camera. Good point, its sensor is very sensitive and we saw very close image quality in low light.

Most observations made during the day are still valid at night. The A1 4MP delivers a brighter image than its competitor, making it possible to distinguish more shapes and details in dark areas. However, the amount of detail is limited, especially since a little noise is added here. The image quality is not bad, but a face cannot be identified beyond 2 meters. We estimated this distance from Evis with the C6W to be 3 meters.

Another small disappointment is that the Emo’s camera takes almost 10 seconds to activate its night vision, but its motion detection is useful. It took about 8 meters in front of the camera to start receiving alerts, which is good for an indoor camera.
