smokingjoe 0 Posted November 11, 2018 Hi all I need help with a Qsee System. I do not have a lot of experience with analog systems. QT4760 16 channel DVR. This DVR is about 5yrs old. I am trying to add two new cameras. QCA8045B. When I connect the cameras to the DVR they do not show up. I am thinking that it may be a compatibility problem but not sure. What do I need to be looking for when I am buying cameras that will work with this DVR? Thanks Back again After doing a little searching it seems like QSEE had different series cameras. I am seeing QT, QTH and QC. The cameras that we bought are QC. I am guessing that since the dvr is a QT4760 that maybe I need cameras that start with QT. Is this the only thing that I need to be looking for? Share this post Link to post Share on other sites
tragic_audio 1 Posted November 12, 2018 Hi! Your dvr works with analog cameras (cvbs), with resolution 960h or D1. Your new camera works in new standard Analog High Definition (aka AHD) with resolution 2mp. It's incompatible with your dvr. However some ahd cameras can switch to cvbs mode via wire joystick or locking special wires if they present. What do I need to be looking for when I am buying cameras that will work with this DVR? You need buy any CVBS cameras or AHD 4in1 cameras (can switch to cvbs mode) Hi allI am guessing that since the dvr is a QT4760 that maybe I need cameras that start with QT. No, actual Qsee models wth QT not compatible with your dvr. There is AHD cameras. in my opinion Qsee not a good choice afterall. They have no detailed photos and instructions in their site. Therefore it is difficult to choose right. Share this post Link to post Share on other sites
smokingjoe 0 Posted November 13, 2018 I thank you for the reply and the information. I will order two of the CVBS/960h cameras. It sounds like this will get us going again. Thanks and have a good day. Share this post Link to post Share on other sites
