While it's a little more expensive than budget cams, this EufyCam is 40% off for Prime members, with an unprecedented opportunity to get rare features like Apple Home compatibility and object recognition with no additional fee. It also offers a 2K resolution and IP67 weatherproof rating, as well as night vision. You don't usually see a high-end outdoor cam at this price, but keep in mind, if you want video storage, you'll need to buy a Eufy hub and microSD card. Or you could choose this two-cam Eufy package that comes with a hub and is $110 off thanks to a similar deal. 

Pet cameras can watch out for intruders, but their primary focus is the Fidos and Felixes in our homes. They can be expensive purchases, but this sale cuts the price by nearly a third. This HD camera has Alexa built in and can provide motion and audio alerts, along with night vision. It even has one of those little treat dispensers to interact with your pet -- just don't overfeed them when you're away. 

TP-Link's affordable Tapo system includes two 2K-resolution cams and a connection hub, ideal for a front-and-back camera setup at your home. The cameras are weatherproofed, come with 49-foot night vision, and allow you to set activity zones for identifying people, pets and vehicles. They're all-purpose outdoor security cams that can fill many roles, although you may want to grab a microSD card if you don't plan on using the Tapo subscription service.

Ring is one of our top picks for easy DIY installation if you want a speedy system equipped with door and window sensors. The five-piece model is a perfect starting point, and this bundle throws in the Ring video doorbell for front door protection as well. A Ring subscription (starting at $5) is a very good idea, but it's still an excellent choice for a discounted starter kit.

If you're a fan of Ecobee (its products work reliably with Apple HomeKit, Alexa and more) you can deck your home out in Ecobee security and a smart thermostat with this deal. Save on a start sensor pack, an Ecobee video doorbell and the Thermostat Premium.

Finding a large home security system can feel frustrating if you don't want to spend hundreds of dollars and risk getting locked into a contract.

Included in this kit is a base station, keypad, pack of entry sensors, motion sensor, key fob, siren and smoke detector. That makes it an effective DIY way to outfit a new home or apartment that's never had security tech before.

The lock also has excellent compatibility, working with platforms including Alexa, HomeKit, Google Home and Samsung SmartThings.
