MattFlah 0 Posted March 10, 2015 Hi, I was wondering if anyone had any experience in using AHD cameras? I'm looking at getting a full AHD system, but will start off using the cameras in my current DVR (budget issues) then later on upgrade the DVR to a proper AHD one. From what I can tell as the cameras are backwards compatible with 960H and regular analogue there should be no issues using them in the DVR. Does anyone know practically how this will actually work? Is there just a switch on the side of the camera putting it in D1 resolution? Can I easily change the resolution back to 720p when I change the DVR? Thanks a lot Share this post Link to post Share on other sites
centralalarms 0 Posted March 10, 2015 Get HDCVI. Plenty of low-cost hdcvi tribrids are available in the market that support D1/960H/720P HDCVI on every channel plus 2 IP cameras. Stay away from AHD. You will end up with a system with no cameras for it in the future just like the current situation for HDSDI Share this post Link to post Share on other sites

centralalarms 0 Posted March 11, 2015 Thank you Korean and Chinese manufacturers for polluting the forum. AHD is great in Europe and not going to go anywhere. TVI may have a chance alongside with HDCVI. Stop misleading people! Share this post Link to post Share on other sites
SunnyKim 2 Posted March 12, 2015 Apology for being offended any bit. HD CVI is for Daihua. HD-TVI is for Intersil and HikVision, basically open to any suppliers. AHD runs the same track. HD SDI keeps lowering price. We all know how terrible Monopoly could be. Why not let them dog fight for lowered price and better quality? The benefit goes for end users, I believe.

joseph.chen0312 0 Posted March 17, 2015 Wow, "misleading" is a heavy word. Actually, pick which solutions or products all depedns on local channel promotion, education, service and intrinsic quality. Even for TVI supplier but offer different qaulity, service, lifespan.. More turth, some turnkey provide has announce some solution for intergrated AHD and TVI. And CVI has already integrated SDI be alliance. Who knows someday TVI, CVI and AHD able to all in one, same as IPC. Share this post Link to post Share on other sites
