Bought a new analog DVR upgraded all my indoor cameras to 2MP TVI models without issue. I was hoping to do the same for the outside, but they were installed with an interesting mount and it seems far from universal to find a replacement camera that fits the same mount. Here are a couple pictures: https://photos.app.goo.gl/cC5nvQYEjGgL38hC2 https://photos.app.goo.gl/yAe7vM2PE3JVEsLz7 Can anyone offer any leads or recommended stores to find something new that we can just swap in and use the existing cabling and mount to get these up to 1080P?
