Rather than trying to decide among a ton of identical-looking standard-definition devices, today's DIY market is flooded with a wide variety of high-definition outdoor-rated models.
Some have to be hardwired to an existing doorbell or light fixture. Others rely on batteries. Some have optional cellular backup and others still come with a unique assortment of accessories so you can find the perfect install spot for your home.
Read on to discover the wide world of outdoor home security.

Arlo Essential Spotlight Camera
The $130 Arlo Essential Spotlight Camera takes a lot of the good things about Arlo's Pro line of cameras and puts then in a more affordable device. The Essential cam's rechargeable battery isn't removable, though, so you'll need to bring the whole thing inside to charge it.
The Ezviz DB1 Video Doorbell costs $200. It has a built-in microSD card for local storage that is supposed to support cards (not included) up to 128GB. It's also supposed to work with Alexa and Google Assistant.
Nest's $200/£150 outdoor camera is similar to its indoor model.
With 1080p high-definition live streaming, motion and sound detection, activity zones, IFTTT integration and integration with other Nest products via the related Android and iPhone app, this camera can do a lot.
You can do even more with a monthly subscription to the Nest Aware service, including Person Alerts. This feature shoots you a notification both when it thinks it sees a person and when it's sure it sees a person.
The $249 Maximus Camera Floodlight is a hardwired floodlight camera that replaces a traditional floodlight. The Maximus comes with two hours of free cloud storage, and it sent prompt motion alerts to my phone.
Pay an optional monthly fee for access to person alerts and customizable motion detection zones.
The Maximus Smart Security Light (formerly Kuna) is a seriously cool device. It's an outdoor light fixture with a built-in security camera hiding in its base.
Of course, that means you'll have to uninstall an existing fixture to get the hardwired-only Maximus up and running, but it's a clever, discreet way to watch over your front or backyard in 720p high-definition.
Like the Welcome cam, Netatmo's Smart Outdoor Camera (formerly called the Netatmo Presence) has a facial-recognition feature. That means, it's supposed to be able to tell the difference between people and well, everything else.
It also works outside and offers zones, as well as 1080p resolution and a 100-degree field-of-view.
The battery-powered $199 (£150/AU$260, converted) Ring Spotlight Cam has built-in LEDs, motion detection, 1080p HD live streaming and two-way talk. An optional solar-powered model is available for $229 (£170/AU$300, converted).
Ring was one of the first startups to offer a DIY smart doorbell.
Its second-gen Video Doorbell, available in the US for $100 has a rechargeable battery. The rechargeable battery isn't removable, though, so you'll have to remove the whole doorbell whenever it needs to charge.
The $199/£155/AU$299 Ring Video Doorbell 2 can either be hardwired or you can use the removable, rechargeable battery. It has 1,920x1,080p HD resolution, a 160-degree field of view and optional 60-day storage for $3 per month. This model works with Amazon's Alexa, IFTTT and Wink.
The $150 Tend Secure Lynx Pro is an indoor/outdoor home security camera. It comes with free seven-day event-based cloud video storage, built-in local storage and battery backup. It supports Alexa and Google Assistant voice commands and has a weatherproof exterior.
The Wyze Cam Outdoor Starter Bundle costs $50. For your money, you get the camera and a base station. It has two weeks of free cloud storage like the indoor camera -- and a built-in microSD card slot for local storage (microSD card not included).
