    @Slyfox

    Thanks for the tip, however overheating will be a common issue for HD dvr due to the encoding work it does compare to d1/cif dvr.

    Looking at the image we can therefore conclude that HD dvr works 3x++ harder than d1/cif dvr. HDD are also subject to tramendous work specially if you let all channel to record at 25 fps.

    To avoid and prevent overheating, it is always recommended to lower the recording fps and utilize the motion based recording when applicable. I heared the 7-8 fps are still industry practice but for me reducing to 15-18fps from 25fps is huge reduction on the workload of both the hd recorder and HDD.

    if you search for alibaba, most if not all cctv manufacturer offer AHD camera and dvr. AHD are gaining tramendous adaption due to price and ease of deployment. Some website even mention that sales of ahd are starting to surpass sales of ip, sdi and cvi system.
