The pixel requirements of home surveillance cameras vary due to various factors, including the size of the monitoring area, monitoring purpose, viewing distance and storage requirements. Here are some general considerations:
Monitoring area size : If large areas need to be monitored, such as the whole room or outdoor courtyard, higher pixels can provide clearer images, which is helpful to identify details and character characteristics.
Monitoring purpose : If it is mainly for general monitoring and security purposes, the camera with lower pixels may be enough. However, if clearer images are needed to identify faces, license plates or other specific details, higher pixel cameras may be more appropriate.
Viewing distance : A closer viewing distance may not require very high pixels, while a longer viewing distance can ensure that the image is still clear and legible.
Storage requirements : Cameras with higher pixels usually produce larger image files, which may increase storage requirements. When selecting pixels, you need to consider the capacity and storage cost of the storage device.
Generally speaking, for home surveillance cameras, 1080p (full HD) or more pixels can usually provide good image quality. This means that the camera has a resolution of at least 1920x1080 pixels. However, specific pixel requirements should also be determined according to individual needs and budgets.
Here are some examples:
For smaller monitoring areas or close viewing, a 720p (high-definition) camera may be sufficient.
For situations requiring clearer details, such as monitoring doorways or important areas, 1080p or higher pixel cameras may be more suitable.
If there are special monitoring needs, such as recognizing facial features or license plate numbers, cameras with higher pixels, such as 2K or 4K, may be required.
In addition, other characteristics of the camera, such as night vision function, wide-angle lens, image stability, etc., should also be considered. These factors will also affect the monitoring effect. When choosing a home surveillance camera, it is best to consider comprehensively according to the actual needs and compare different models and pixel levels to select the most suitable product.
It should be noted that pixels are not the only factor to measure the performance of the camera. Other factors such as lens quality, sensitivity and image processing capability will also affect the image quality. At the same time, ensure the legal and compliant use of surveillance cameras, and respect the privacy of others.
