Not much info unfortunately. Some of them apparently use a HiSilicon (owned by Huawei) chipset; the following Alibaba page lists some of them among others. htt

Not much info unfortunately. Some of them apparently use a HiSilicon (owned by Huawei) chipset; the following Alibaba page lists some of them among others. https://www.alibaba.com/countrysearch/CN/dvr-motherboard.html https://www.alibaba.com/countrysearch/CN/dvr-motherboard.htm... Here are a few pages I found that could turn out interesting: https://securitycamcenter.com/firmware-chinese-dvr-nvr-security-cameras-h264-h265/ https://securitycamcenter.com/firmware-chinese-dvr-nvr-secur... https://github.com/hisilicon https://github.com/hisilicon And as widely reported, they're quite vulnerable. https://github.com/tothi/pwn-hisilicon-dvr https://github.com/tothi/pwn-hisilicon-dvr https://www.exploit-db.com/exploits/44004 https://www.exploit-db.com/exploits/44004 I wonder if those vulnerabilities could be used to gain root access to the hardware in order to either patch it and make decent security devices, or repurpose them completely, as the hardware is interesting and dirt cheap.
