This is a 2MP Indoor/Outdoor Dome Security Camera that is capable of working with CVI, TVI, AHD and Analog! We've been getting so many requests for Analog replacements and this finally fills that void. You will be able to stream a pure TRUE HD 1080p signal to your DVR that will capture amazing detail. You know how important it is to be able to record everyone coming in and out of your home, office, store, etc. so that if anything should happen, you have proof of the crime in your surveillance footage. As the technology continues to gravitate to HD over CVI and TVI, many people still want to hang on to their Analog recorders amd this is a great way to do that and eventually move into the CVI or TVI.
