    I purchased https://www.amazon.com/gp/product/B01C6KUKMY/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 and https://www.amazon.com/gp/product/B07DFKTKGG/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1. Upon arrival 3 cameras arrived broken. After about 10 emails going back and forth with their customer service and them assuming Im just too stupid and unable to get the broken cameras working they requested I send the cameras back. [the cameras would not get registered by the NVR or through the network in anyway. The IR LED would flick on and off but everything else would remain dead. I tried resetting everything and went through every hoop. In the picture you see the cameras are connected but the led indicator on the back of the NVR does not light up meaning they are in no way recognized. Reolink refused to accept this...] I ended up paying out of pocket to ship the cameras back to them because of some complications with returning it through amazon. Once they go the cameras back they told me they couldnt ship the cameras out to me because they were incapable of creating the shipping label. Yeah okay... Instead they just linked me to individual cameras on amazon to just repurchase the cameras through amazon, so spending another $150ish claiming that they would just refund them once they arrived. I ended up just having to go through Amazon instead of trying to communicate with Reolinks customer service. Amazon saved the day and just issued a refund to me. If you have the luck of the draw and dont receive any problems then these cameras are okay. Just okay. The picture is okay. Not amazing or great. Just okay. Cant read a license plate from 40 feet away. Im guessing down the line once the cameras begin to show their durability trying to warranty these guys is out of the question. Im going with another company next time. You get what you pay for.

    I have several of these cameras and I like them they are good value and a good quality for the price. I needed to add an additional camera so I just received this one and even though it the same model number the base is different. The older ones have one hex screw that you loosen and you can adjust the camera , very convenient. The one I just received has what I can only call a giant wing nut that you loosen to adjust the camera. I guess it’s not a big deal but the older one with the hex screw I like better and it feels sturdier.

    So Im a noob at security cameras, but the whole kit I bought came with 4 cables for the included cameras. I realized this when it arrived. Would be nice if the advertising mentioned this like most items that need batteries mention they arent included etc.

    Like the cameras the night vision could be a little better. The overall system is great.
