We haven't heard anything directly from Hikvision support but we did have a customer with a series of problems with their cameras connected to an NVR running the latest firmware (v4.21.005) and they updated their G1 cameras (2xx5/2xx3) to the new v5.6.0 firmware and that fixed almost all these compatibility issues with the NVR and so it may also fix the motion issue in playback. You can find the camera firmware here: DOWNLOAD EU PORTAL
I thought we had mentioned this in an earlier post in this thread but just scanning through I don't think we actually did but yes the first 4.21.000 firmware did introduce a new plugin that is supported by Chrome, Firefox, and others. You may get a basic live view on this firmware without installing the plugin, but for full access to all settings & playback you will need to install the new plugin which is linked in the top left of the live view page when you log in to the NVR. This 'new' plugin is not yet a full solution because it downloads as a .exe PC install file and there is not yet a Mac compatible plugin file so Chrome on Mac still does not work properly.Maybe I missed the discussion - but has anyone else picked up on the fact that 4.21.008 no longer requires Internet Explorer with web components? It works in regular old Chrome.
