AmazonSome things change over time, but the desire to keep your home safe and secure isn't one of them.

In the past, setting up security cameras meant putting holes in your walls and running cables to an expensive video-capturing and monitoring station.

Thanks to Wi-Fi and smartphones, you can get similar results using free-standing, internet-connected cameras, and in that group, one of the most popular options is the Canary.

It's only 6 inches tall, but the camera has a 1080p lens with a 147-degree viewing angle and ambient light sensor, a 90-decibel siren, and sensors to test your home's temperature, humidity, and air quality. You can check on any of these stats at any time by connecting the Canary through an iOS and Android app, which is also the way you receive notifications.

Although it's there for your peace of mind, getting alerted at every movement in your house is annoying. This camera learns about the general activity in your home, so you're notified only when something seems off. If it's an emergency, you're given the option to call the police right from the app and use the camera's siren to alert the person in your home that they've been caught.

Unlike a lot of other options, Canary doesn't require a monthly fee to save the clips it records. You can view and save recent ones to your phone's camera roll after reviewing them. If you'd like for Canary to store them in the cloud for a month, there's a $99 annual subscription.

Finally, the Canary does away with the need for cord clutter by charging through a microUSB cable, thin enough to coil up or hide from plain sight. You can also plug in an Ethernet cable if the Wi-Fi in your house is spotty or you set the camera up close to your router.

If you've been looking for an easy way to feel a little safer about your home or apartment, the Canary can offer that to you at a better price than usual. Right now, it's within $1 of its lowest price ever on Amazon, but there isn't an official sale going on, so it could bounce back at any time.

In this case, waiting could be the difference between being safe and being sorry.
