Hikvision — pc heating when cctv is displayed

My Laptop is burning hot whenever the CCTV is displayed for a period of time. It gets hot ONLY when the CCTV is displayed (it is displayed from the internet by searchung the IP address). The previous version of HIKVISION did much better because it did not get hot. But the new version is really bad and needs some fixing to do. My laptop has been forced to shut down because its too hot. Please fix the problem or provide us with a solution.
