A video doorbell is probably the single most useful security device you can add to your home. You see who's at the door from anywhere, get alerts when packages arrive, and have a recording if something goes wrong. But there's a huge range in quality and ongoing costs, and the wrong choice means constant false alerts and a subscription you didn't budget for.
Go wired if you possibly can. If you have existing doorbell wiring (most homes do), a wired doorbell is better in almost every way. No battery hassle, more reliable video, and features like continuous recording become available. Battery models are fine for renters, but you'll be pulling them down to charge every 1-3 months. Check your transformer first though - most wired doorbells need 16-24V AC, and older homes sometimes have weaker transformers that need swapping.
Subscription costs are the hidden price tag. Almost every doorbell limits what you can do without a plan. Ring charges $4/month for video history. Nest requires Nest Aware ($8/month) for continuous recording and familiar face detection. Some brands like Eufy offer local storage with no subscription, but you lose cloud backup. Factor in a year of subscription costs when comparing prices - a cheap doorbell with an expensive plan isn't actually cheap.
Field of view matters more than resolution. Everyone focuses on 1080p vs. 2K, but the angle of view is more important. A narrow field means you see someone's face but miss the package to the side. Look for at least 150 degrees horizontal. Some newer models offer a head-to-toe aspect ratio that's genuinely useful for seeing packages on the ground.
Package detection and smart alerts are where the real value is. Basic motion detection will blow up your phone every time a car drives by. Look for doorbells that distinguish between people, packages, animals, and vehicles. This is usually a subscription feature, but it's the difference between useful and annoying.
One practical tip: test your WiFi signal at your front door before you buy. Doorbells need solid WiFi to stream reliably, and if your router is far away, you might need a mesh node first.
