tomcctv 187 Posted January 20, 2017 Hi. Over 10 years old so no support it's also a CIF low quality recorder you also need proprietary viewer software. You also have to match software for the region of dvr ... In your case ZM .... Put anything else on and you can't change back Share this post Link to post Share on other sites
