Among combination smoke and carbon monoxide alarms, the First Alert SCO501CN 3ST Est. $50 looks like a top choice. Like the First Alert SA511CN2 3ST discussed in the section on photoelectric smoke alarms, the SCO501CN 3ST uses radio technology to set up a wireless network with other First Alert interconnectable alarms smoke, CO or combination without the complications that a hardwired interconnected alarm system would entail, though you might need to experiment a little with alarm location to make sure that each unit is within range of at least one other interconnected alarm. Reviews of the First Alert SCO501CN 3ST are mostly strong. It receives a recommendation from Consumer Reports for its performance as a CO detector, but only a middling rating as a smoke detector as it only has photoelectric sensors for that function once again, Consumer Reports only recommends smoke detectors with both types of sensors, though not all experts agree that those types of alarms are the best option. Still, the SC501CN's performance earns the highest possible grade both when it comes to smoldering fires, and as a CO detector.

In some implementations, the server system 164 is a video processing server that provides video processing services to video sources and client devices 220. In some implementations, each of the video sources 222 includes one or more video cameras 118 or doorbell cameras 106 that capture video and send the captured video to the server system 164 substantially in real time. In some implementations, each of the video sources 222 includes a controller device not shown that serves as an intermediary between the one or more cameras and the server system 164. The controller device receives the video data from the one or more cameras, optionally performs some preliminary processing on the video data, and sends the video data to the server system 164 on behalf of the one or more cameras substantially in real time. In some implementations, each camera has its own on board processing capabilities to perform some preliminary processing on the captured video data before sending the processed video data along with metadata obtained through the preliminary processing to the controller device and/or the server system 164. In accordance with some implementations, each of the client devices 220 includes a client side module.

So when it came to making sure it only picked up motion at the front door and then the front yard I didn’t have to worry about motion that was happening with cars driving by only when someone actually walked up to the front door or through the pathway to the front door.
