    SDi V IP

    Hello Everyone! This is Mike, we are a manufacturer of SDI, TVI, CVI and IP cameras. 4CH SDI DVR Kits with 20m IR distance, Factory prices is $330.0. For comparison of SDI, TVI, CVI Image quality: SDI better than TVI and CVI System Cost: CVI and TVI low than SDI Stability: All quality are stable Color rendition: SDI better than TVI, TVI better than CVI CVI color is light than real, TVI and SDI is close to real but little deep. Coaxial Protocol: TVI and CVI support, SDI under research Power on Coaxial: All under research AF Zoom(Auto Focus): All support For IP Indeed, wireless is not very safe than wire in Europe countries. Since network in Europe is so cheap, and if thieves know the frequency of IP cameras, he will know how to interfere signal and IPC don't alarm. if wire IP cameras, the cable may be cheaper, but 1080P signal is 3Gb/s, Cat 5 max 1.5Gb/s, how can NVR ensure there is no pictures losing in transmission? Even compression, it can't ensure losing pictures. After all, it have delay also. If use Cat 6 or Cat 7, this problems should be solved, but delay still exist. So need to wait good solutions to reduce delay. Any more questions, you can send emails to me.
