Unfortunately I am very disappointed with AX Pro. And this is coming from someone extremely tech-savy and very excited to switch to it.
I have the DS-PWA96-M2H-WE and the multitransmitter to convert the older but very reliable wired sensors. Bear in mind that my usecase may not apply to you, as I have a very large setup.
Pros:
1) Can integrate it into Home assistant for more automations. This was one of the main reasons I bought it and perhaps the only reason other than the cost that I still keep it.
2) Same app for NVR
3) I had an installer do the connections with the wired sensors, but the alarm setup itself was fairly straightforward inside the app.
4) Auto-bypass zones when arming the system. However, manual bypass takes quite a few steps and is cumbersome.
Cons:
1) Wireless performance is horrible, coming from the wired DSC Powerseries neo with some extremely good wireless sensors and fobs. The remote fob is useless and has very limited range. I had to buy 2 wireless range extenders, but sensors AND fobs need to be connected to a specific range extender. This is stupid in this day and age where we have mesh systems, as eg I have to think about which extender each fob is associated with to use it, otherwise it doesn't work. Oh and sensors cannot be updated if they are connected to an extender, so this means that I cannot upgrade sensors on older firmware as they are too far from the main panel in the basement. Some sensors are installed on fences so they are impossible to reach and take down without becoming Spiderman. And it seems to me that the range extenders cannot connect to other range extenders, so the final range is again limited.
2) Adding to (1), sensors keep going offline at random times and then come back in a few hours or days, whatever.
3) Navigating inside the Hik-Connect app is sometimes laggy, especially going back and forth between NVR and alarm if need be. But the worst thing is that if the app is in the background and I open it again after some time, it doesn't automatically update with the state of the alarm. So it can show wrong state of the alarm status (eg show armed, when in fact it's disarmed)! There's a 'last updated at time', but for older people, this is hard to notice. The status should update automatically.
4) Some times push notifications arrive a few minutes late. And they don't include the zone that triggered the alarm, so you have to open the app, losing some valuable seconds.
5) When I bought the system, there was no way to have an external 4G antenna. Having the main panel in the basement, means that no signal at all can reach the panel. Input for an external antenna would solve this. Not sure if this is fixed nowadays.
6) This was supposed to be a 'pro' but I was severely let down: Intrusion verification with the connection of NVR cameras. First of all, cameras connected directly to the NVR were impossible to setup inside AX Pro that I gave up on them and moved them to a separate switch I had to buy. Then, I couldn't connect multiple zones to the same camera.
7) Integration with the Indoor Station DS-KH9510-WTE1(B) is atrocious. It uses older version of Hik-connect with limited features, and is so painfully slow that you cannot use it neither for the alarm nor for the NVR. Oh and it logs out of Hik-connect quite often.
8) No frequent firmware updates. Reports online that the latest v1.30 version bricked devices/broke setups. It has been pulled since February and no replacement is available.
9) Wireless control panels are slow to operate even on the latest firmware version and burn through the batteries quite fast. And perhaps most worryingly, I've had 3 occurences of the panels triggering Panic and Fire alarms by themselves. One was while I was outside the house, and the other 2 were while I was disarming the system.
In hindsight, I totally regret the very expensive investment and should have either stayed with the DSC Powerseries neo (or the qolsys?) or gotten the Ajax system.
Sorry for the long text, but I had to express my frustration with the system.
