Pricing for add-on components is pretty much in line with what you'll pay if you have a SimpliSafe or Abode system. Extra contact sensors are $20 each, another motion sensor will cost you $30, and a range extender goes for $25. Additional devices including a Smoke/CO detector ($40), a Flood/Freeze detector ($35), and a Dome Siren ($30) are not yet available.

You have 2 alarm modes: home and away. Using the app you get to chose which sensors will trip home mode and away mode; to be a little more specific, in the app you can select a sensor and check a box next to away and a box next to home if you want it to trip the alarm even if your alarm is active in “home mode” such as when you’re sleeping at night, where motion sensors inside won’t trip the alarm, but doors or windows opening will do so. You can also select a motion sensor and select a lower sensitivity level in case you have pets. You can do all this from the app even away from home.
The Nest Guard motion sensor can detect motion within a 90° field of view up to 10 feet away. It also includes tamper detection as well as a proximity sensor (wakes on approach) and will let you know if it’s moved or if someone tries to jam your signal. However, in testing, I found that none of the promised tamper sensors worked. I did not test jamming detection.
The abode Gateway also supports limited local functionality. This is in part thanks to the Gateway’s ability to communicate using its own proprietary protocol called abodeRF. If your internet is down, your automated rules will continue to run, assuming that the devices involved are connected to the Gateway directly and not through a third-party service like IFTTT.
I’ve heard others say Arlo is the perfect outdoor camera. I disagree. The original Wire-Free camera had more latency than Arlo Pro. Also, Pro includes a wider field of view, a rechargeable battery, a siren (built into the hub), and it adds sound with two-way audio, all features the original Arlo lacked. Arlo Pro 2 bumps up the resolution to 1080p and adds three features if the camera is plugged-in: CVR, Motion Zones, and Look Back.
Nest Secure’s monitoring service is provided by Brinks Security. Originally, service was offered by MONI before MONI, LiveWatch, and Brinks merged to form the Brinks brand. Monitoring of Nest equipment through Brinks is $29.00 per month plus the cost of equipment. If purchased through Brinks, equipment is only $299 for Nest Guard, two Nest Tags, and two Nest Detect Sensors. If you want a discount on Nest Secure services, your only option is to sign a contract. With a three-year contract, you’ll pay $19.00 per month; equipment remains at $299.
The Z-Wave range extender and the sensors in the kit are pre-paired with the base station, so you just need to enroll them into the app. Ring also sent me a couple of add-on door/window sensors so I could experience the full onboarding process. This simply involves scanning a QR code on the device, verifying that the PIN printed below the QR code matches what’s displayed in the app, and then pulling the battery tab.

The next step is camera placement, and Arlo Pro offers a few options. It can sit on a flat surface, stick directly to a metal surface (magnetic), or you can use the included plate to mount it to a wall. While you can place Arlo inside or out, the camera’s power cord that ships with the package is not weatherproof so plan to use battery power when placing the camera outside. If you’re willing to spend an extra $25, you can also buy the weather-resistant outdoor power adapter (VMA4900) that works with Arlo Pro, Arlo Pro 2, and Arlo Go. Finally, they also sell an $80 solar panel. The panel works with Arlo Pro, Pro 2, and Go, and can power one camera continuously. Keep in mind, however, that the solar panel only powers the camera. It does not charge the camera’s battery.
Finally, unlike abode’s base station (iota does not require Ethernet), Ethernet is not required to use Nest Secure. Nest likes to make things easy and they send everything you need, including batteries, to get your device up and running. Nest Guard ships with a 6-foot cable with a power adapter and CR123 batteries for the sensors. My system already had the batteries installed which made setup even easier.

When we tested out the accuracy of the motion and contact sensors, we were impressed with how quickly our app registered movement. Opening the door meant that our app automatically showed the “faulted” icon indicating movement – in fact, it was almost instantaneous. Same for the motion detection sensor – the notification on both the hub and the app appeared almost immediately. This was the case whether we were in the house or not. With some devices we’ve tested, particularly with security cameras, there’s often a lapse with notifications. It doesn’t appear to be the case here.

Ring, an Amazon company, also sells several security sensors. First is the keypad. The keypad runs on battery power, and you can wall mount it or place it on a flat surface. In addition to arming and disarming your system, the Keypad Control Panel allows you to choose between Armed Away and Armed Home. When using the keypad to arm your system, it provides a grace period to reduce false alarms. You can customize the grace period using the mobile app. Finally, you can simultaneously press and hold the check and x buttons for three seconds to trigger the panic alarm.
