Dahua DVR Problem - Changing ip address, HACKED, Password Lock and no display after online

We have a Dahua DVR DH-DVR5116H and other model, the problem is  changing ip address, the port numbers, PPPoE user name, HACKED, Password Lock and no display after online. we have reset it to default and everything backed to normal and we have changed everything and we are wait for 2 hours and the same thing happened again, we thought someone is hacking it but when we check in the logs there was my login at that current time we logged in and out and present the time we logged in. The technicians said is firmware update, we update the new firmware for the current version.


Tip for you and solve this problem

(1) There is a group of people hacking into Dahua DVR's all over the world, we are experiencing allot here is Gujarat, what you need to do is disconnect your DVR from the network, do a complete factory default, add two new users and passwords , delete the admin user, change ports and upgrade your firmware before connecting it back to the internet.

(2) if you connect dvr with internet and after some time no display in dvr,

      a) first contact to service center and repair it
      b) secound contact to technician of company  for security firmware update.
      c) do online only P2P ( for security ) if your dvr not support p2p you can use other service
