I recently upgraded to a Qolsys IQ Panel 2 Plus from a antiquated panel. The Qolsys panel is really responsive compared to my old panel. Video streaming is really good on the Qolsys. It uses Qualcomm Snapdragon SBC and Android 5 SE. Thus, it does have a lot of computing horsepower.
The touchscreen user interface is really clean and modern.
One feature that I really like is the Skybell doorbell camera. It allows me to view and talk to the person at the front door using my cell phone.
I've also added Alarm.com, a cloud based services provider to the mix in order to do remote control, home automation, monitoring etc. The Alarm.com rules engine is fairly advanced but is flexible and easy to use. I'm afraid I might get carried away with creating rules.
Overall, I'm satisfied with this new system.
