Digital ZoomDigital zoom allows you to select part of the video and enlarge it. While this helps you get a closer look at something, the quality of a digitally enlarged video won't match that of the original. The Samsung SmartCam HD Pro has the highest digital zoom in the review at 10x. Smart Home PlatformBefore you buy, check if any home automation or DIY home security systems work with the camera. These systems can use Wi Fi security cameras to control smart locks, thermostats and other devices in your smart home. Likewise, these devices can tell the camera to record or not, based on your personal preferences. The biggest appeal with these systems comes from using a single app to control all of the smart home devices. WarrantyIt is common among consumer electronics to find a one year warranty. Longer warranties give you more time to replace the unit if it stops working due to a manufacturing defect. The longest warranty we saw, found on both the Nest Cam and the Belkin NetCam HD+, is two years.
