I have Arlo on one house and Blink on another. Both give me adequate results and they do not require a subscription. I did recently replace one camera on my Arlo system after ten years. I bought an Arlo Essentials camera and I have to say that the picture quality is much better than the original. It still works with my original base station and it gives me great pictures even at night. I bought it on Amazon and it was just $50. I don't know what a complete system would cost, but I am happy with my old base unit and the new camera. One other option is the single screw in cameras that fit into a light socket. I put two of these in our antique store and they are amazing. You can sign into them remotely and you can rotate the camera to see anything in the area. The ones that I bought look to be typical Chinese junk but they work great and they are just $25 each. They even have built in night illumination that actually works well. We also have a security system in the store, but I never look at that because the movable cameras give you so many options.
