We have a pro version and have no ad. Support more new type dvrs. Because these new type dvrs default port is 37777 or 34567 or 8000 or 5800 or 8101. And some old dvr port maybe is them too. The app mistakenly believes that the old dvr is a new type device. That causes the app can not work well for it. We use a method to solve it.
