It depends on your specific needs. While H.265 CCTV security cameras are relatively new, they are becoming more accessible. However, their higher price point may be a factor to consider.
Moreover, H.265 IP cameras are designed primarily to deliver ultra-high definition videos, such as 4K and 8MP, making them ideal for monitoring large areas that require greater detail. Thus, if you need to cover relatively smaller areas and have a tight budget, an H.264 security camera would be enough to produce 5MP/1440p/1080p videos with necessary details.
