Another reason why RING is killing the competition is that their batteries last sooo long. With regular everyday use, I’ve seen units last several months before they need to recharge which is very easy to do. Some of my clients even have several RING video doorbells covering their front door, backdoor, enclosed fence and garage entrances. Screwing in the camera to the front door itself is very popular as well since you can get the perfect height and center view for your cameras. Now it is better to use your existing wiring if you can because you don’t have to worry about battery charging but if it’s only one or twice a year, I don’t think most people would mind. Also, it charges like a mobile phone. Plug in a USB charger for a few hours and you’re ready for several more months of video surveillance. My first doorbell client had his system running for a month before the Ring doorbell battery indicator showed it was at 95%. That means only 5 % of battery power was used for the whole month. Charging the RING battery can take 4 6 hours using a mobile phone USB chargerNow again, the aforementioned video doorbell units from other companies are good but if you want the flexibility of placement without wiring or rewiring your doorbell configuration then you need a RING.
