You can use HTML, or find another IP-cam viewer. None for the price you are paying now: Free...
I have not yet find a good and free viewer with same options. So I have a dedicated computer, with remote playback and live viewer services switched on... But I need to record multiple cams, and there is what most free ip-cam viewers restrict you on. For 1 camera there are some options, but I have looked some time ago, so my info is not up-to-date...
Happy hunting for a viewer!
