Which DVR or NVR is Compatible with Q-SEE Cameras?

To determine which DVR from CCTV Camera World with your existing DVR, we would need the model number of your Q-see DVR. While we're all looking for quick and easy answers, doing some fact finding about the model of your current DVR will save you a lot of time and hassle.

The model of a Q-see DVR is usually located in the front of the DVR, or on a label on the bottom of the DVR. In the image below we show some actual examples of what the model number may look like on your recorder, either it be a DVR or NVR.

Examples on what a QSEE model number label looks like

Q-see carried 3 different lines of security camera recorders. We've listed them below and written some notes about each series:

QC Series

You may have an analog DVR or an NVR for use with a PoE Camera. Regardless of which type, we carry both cameras and recorders that are QC series friendly. You just need to confirm the model number of your recorder so we can confirm what's the highest resolution supported by your DVR NVR.

We offer DVR recorders in two varieties:

  1. Max Support for 4MP 2K security cameras
  2. Max Support for 4K security cameras

Our NVR recorders all support a max of 8MP or 12MP depending on the model.

QT Series

The QT series surveillance camera recorders by Q-see were sourced from two different manufacturers and are the most difficult to replace. For suggesting a replacement recorder we need the model number of the Qsee DVR or NVR that you have. It is too complicated to explain how to choose a suitable replacement, and we suggest replacement models ourselves.

Knox Series

The Knox Series by Qsee was an NVR system which worked with an IP Camera only. The Knox Series NVRs worked with Presidio Series IP cameras from Q-see. Our NDAA compliant security cameras and video recorders are compatible. Please email us the model number just to be sure.

Frequently Asked Questions (FAQ)


Are all QSEE cameras compatible with Avalonix DVRs?

No. 90 percent of QSEE cameras with a BNC connector, on the other hand, are compatible. HD-SDI is the only signal type that Avalonix DVRs do not support. Fortunately, HD-SDI was not widely used in the security camera business, and QSee did not carry it for a long time. CVI, AHD, TVI, and analog CVBS signal types are all supported by Avalonix DVRs.

Our DVRs also function with most QSEE IP cameras when connected to a local network using PoE switches.


What resolutions are supported?

The resolutions supported are determined by the Avalonix DVR model you purchase. We offer two security DVR lines: 4K 8MP and 2K 4MP. The following resolutions are supported by our 4K security DVRs: 4K 8MP, 5MP, 2K 4MP, 1080P 2MP, 720P, and analog resolutions down to CIF. With the exception of 3MP, our 2K security DVRs support resolutions of 4MP and smaller.

Do your systems have remote access to view security cameras?

Yes! With the purchase of a compatible security DVR from our website, you get free remote access and viewing. In fact, our iPhone iPad App for Remote Viewing Your Security Cameras article gives you a sneak peek at the mobile app and how to use it. Yes, the app is also available for Android.

Can I use my existing cable that is already installed?

The short answer is, yes, you'll be able to use your existing installed cable when replacing your QSEE DVR in most cases. It's worth noting, however, that QSEE typically sold systems with thin pre-made cable that couldn't support ultra HD 4K quality. If you want to update any of your cameras to 4K or 8MP, you'll need a high-quality roll of solid copper RG59U cable and connectors.

Do you provide technical support?

Yes, we offer free technical support by email for the life of the security DVR. On request, we also offer paid remote phone support that can be scheduled on an appointment basis. Depending on the support queue, our email support response times usually range from 15 minutes to an hour or two.

Is there a demo of the DVR?

Yes. We have a comprehensive tutorial on How to Use a Security Camera System, including videos that demonstrate the majority of the basic features on our security DVRs.

How do I know if my QSEE recorder is a DVR?

BNC connectors are used for video transmission on security DVRs. Ethernet or network cable interfaces are available on security NVRs.

Please do not hesitate to contact us if you have any questions on which DVR to buy.
