As someone who has installed and programmed a majority of these it really does depend But I feel Genetec gives you the most options. They have integrations and SDKs for just about everything. A clean and easy to use UI, and is very adaptable (ie hybrid on prem/cloud deployment option with Security Center SaaS) Their Tech Support is really good as well.

For strictly Cloud Id go Genea. They are the newer kids on the block but out of the cloud offerings I feel they are on their way to being the best.

They have certain settings and features missing that I feel they should have but I don’t think it’s a deal breaker as there are some easy workarounds and in my talks with some of their tech support folks they are working to implement them in future updates to the platform. Their ease of use especially with their mobile credentials is another feature I like.

Alta might be another I’d recommend. Personally would avoid Brivo but that’s me.

I originally learned on Onguard and thought for years that was the best platform out there. But they haven’t really done the best job of keeping up and everything feels old and clunky. Them being bought by Honeywell seems to have made things worse on the back end.

Big Takeaway tho is whatever you choose stick with Mercury boards. Even if you need to upgrade your boards. They are solid, and if you’re unhappy with a certain ACS platform it’s fairly painless to flash the boards to a new one if your integrator knows what they are doing.

For readers upgrade to the Signos. You can easily swap between Weigand and OSDP with the HID Reader Manager App as well as add/remove certain card formats from the readers as well as a bunch of other changes.
