Let some dvr work continue.

Because some new type dvrs default port is 37777 or 34567 or 8000 or 8101or 5800

but some old dvr default port is them too. The app believes the old dvr is a new type device. that causes app can not work well for old dvrs.

We use a method to solve it.

You need check the Select box for "Only Support old device" in settings, then save it.and exit this app.and then restart app,the old dvr can be support well as before.
