Hi. No it's not possible your unit would also need the hardware components.
If you want to keep using your existing cameras then a hybrid AHD CVI TVI IP is what you need
Can you suggest some models in brands like CP-Plus/Dahua/Hikvision ?
Please suggest a Central Monitoring Software which can work with several analog DVRs. I need a CMS which can provide single window operation for Secureye, Hikvision, CP Plus, Maximus, H.264 (Chinese), etc. DVRs
