ADT Replacement DVR for A-ADT4HS2-500 Digital Video Recorder

My old ADT DVR no longer works and I am looking for a compatible replacement DVR. The model of the DVR on the sticker on the bottom says “Digital Video Recorder A-ADT4HS2-500”. I would like to be able to use my existing security cameras and have the ability to add 4 more cameras to the system. Can you help?

This is the recommendation CCTV Camera Pros provided to this customer:

Yes, we can help. That old ADT DVR model A-ADT4HS2 is an analog CCTV DVR / CVBS format. I highly recommend that you consider one of our Viewtron hybrid DVRs as a replacement. They are available in 4ch, 8ch, 16ch, and 32ch models on this page.

This will allow you to add the additional 4 security cameras at much higher resolution and also upgrade some or all of your existing cameras when you are ready. All BNC inputs on the DVR support analog and HD cameras.

Here are some videos that show the quality and ease of use that you get with Viewtron DVRs.
