What our users are saying
“I've used multiple CCTV apps in the past and they've all had annoying issues like pop up ads or cutting off a podcast I was listening to when I opened it but this one does none of that. Great job and please don't change a thing.”

App Store Review
“My company uses this app almost exclusively which includes over 150 NVRs or DVRs, and 98% are connected right now. This app has been much more reliable and usable than some past providers. Functionally, it works great.”

App Store Review
“I have tested hundreds of apps in my 20 long journey owning a camera installation company. This app is by far the fastest connecting with the fastest server, the easiest to operate, and the best designed.”
