Dahua DVR or something else?

[jokerone 0]

I own a 16ch Dahua that is about 5 years old for my home

 

Some of the cameras have failed (assuming its the camera not the power supply).

 

I'm planning on revamping them. All the cameras are 700TVL but the current DVR only records at D1.

 

So, What are my options for the DVR in the ~$200 range (minus the HD) (keep the current one, replace it, buy something other than dahua, etc.)

 

thanks
