I have purchased many Reolink products, mostly the NVRs, D400 and RLC 520 doing so has lead me down a new career path. I now speak with clients and recommend different Reolink products that would suit their needs then install these products for them. The quality of picture you get from these products is unbelievable compared to other brands that advertise the same product specifications. The price and the option to use Micro SD cards within the Poe cameras has made these easy to sell to my clients because of how cheap I can supply them for and how quickly I can install them I always have a happy client at the end of the install that feel more at ease within their homes. The app is simple for me to use and show others how to use also, I couldn't recommend Reolink enough.
