The company I worked for 4yrs installed Alibi. I will say, support was always 100%. They'd 2day ship everything, overnight stuff when needed and support wise were always there when we called regarding issues, features, tech help, networking issues etc.. Even complaining about designs and features and were responsive because we'd see mounts or bases change. Though, my boss moved a lot of business using alibi, Mostly commercial but also residential. mostly IP, also Analog whatever the scenario demanded.
Im staring at a screen at my work with 5mp system and its pretty good for the price. Ie. last time I checked ( I don't work for them anymore) a 5mp 60' ir was like $50?
For the price it's what I have on my house. But costco lorex has some pretty good deal.
