Facial recognition: A few newer cameras are experimenting with facial recognition. This feature could more accurately be called “facial identification,” as in practice it’s much better at distinguishing a face from, say, a lamp, than it is at actually distinguishing between one person’s face from another’s. If you opt for a camera with this feature, know that it typically learns faces through increasing exposure to them, so be prepared to spend a lot of time in front of the lens.
Local storage: Some cameras include memory-card slots in lieu of, or in addition to, cloud storage, so you can store video right on the device. It’s an attractive feature as it can eliminate the cost of monthly storage fees. The downside (if there isn’t a cloud backup) is that if a crook steals your camera, he takes your forensic evidence with it.
Mobile app: Most of today’s home security camera’s are accessed primarily through a smartphone/tablet app. In addition to offering you a reliable way to view the camera’s live feed, it should offer plenty of options for customizing the way the camera performs. The ability to customize notifications, adjust motion and sound detection sensitivity, and set detection areas are some of the key features to look for. The app should also be intuitive and easy to master.
Motion detection: Assuming you’re monitoring your home when it’s empty, motion detection is one of the most desirable features in a security camera. Built-in sensors pick up movement within the camera’s field of view and trigger video recording. Because these sensors are sensitive to any movement—event a shift in lighting or leaves blowing outside a window—it’s important the camera system also offer the ability to narrow the range of detection, adjust the sensor’s sensitivity, or otherwise customize this feature to cut down on false alerts.
Night vision: Most break-ins occur after dark, so this feature is nearly as important as motion detection. Technically, most home security cameras support infrared LED illumination, versus true night vision based on image intensification or thermal vision. Be that as it may, some camera’s will switch to night vision automatically in low-light conditions, while others allow you to customize when and how it should be activated.
Pan/Tilt/Swivel : Most security cameras—including all the ones in this guide—can be manually tilted and swiveled to focus on a certain viewing area, but this is a purely set-it-and-forget it feature. A true pan/tilt camera is equipped with a motor so that you can move its lens—or even follow a moving object if you're watching a live feed—using its app or browser-based app.
