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.
