High-resolution cameras, such as those with 5MP, produce larger image files, which take up more storage space. For instance, when planning for storage, consider the duration of time you’ll need to keep recordings and the capacity of your storage solution. Investing in ample storage or using a system that allows cloud storage can help manage these larger file sizes effectively.
#3 Mid-to-High-End Camera Price
Higher-resolution cameras typically come with a higher price tag due to their enhanced image quality and added features. While a 2MP camera is often a budget-friendly choice for basic applications, a 5MP camera may be worth the investment if detail is crucial. Balancing your budget with your specific image quality needs can help you choose the right model without overspending.
#4 Suitable for Low-Light Environments
