I'm a bit late to this party, and I don't comment much. However, I felt that I could add something to this conversation. . . good or bad, lol.
Firstly, I appreciate all of the knowledge / opinions / and experience that I am able to leverage from each of you. With the years of experience I can pull from IPVM, you all make my job just a bit easier, and make me seem that much more qualified in the eyes of my clients. _Thank You_
To the OP: You should view each of these recommendations as "movie critic" reviews. At the end of the day, look into a handful that review better than others, TEST TEST TEST, and pick the one that fits your organization best.
With that said, my organization has used the Salient VMS platform for 2-3 years and is our current VMS of choice. Manufacturer support is KEY for us, and Salient does not disappoint. My staff has called them many times over the years, almost always a technician caused issue / mis-configuration. They have been great, and will assist you or your techs in pinpointing the issue, and walk you through the solution. We never feel rushed to get off the phone, and always have that feeling of a "Partnership" during each of our installs.
The VMS software Rarely has issues (most issues we experience are as mentioned above, caused by us). I chalk up the lack of software issues to the fact that the software has not been overhauled in quite some time. This WILL change in short order (check back in Dec-Jan). So the Lack of issues, take that with a grain of salt, and please do not confuse the lack of software updates to mean that they do not update camera support . . . these are updated weekly from my experience. I have only had a few non-brand / end user purchased ebay cams not work. But all in all . . . their camera support and compatibility has been great for us.
Price-wise . . . I don't check this regularly, so I cannot say that this currently is the best priced option. What I will tell you is that simplicity in pricing model, and consistency in tier'd pricing options makes our margins a non-issue for us, or our clients. We make a solid return off of this investment each and every time. Honestly, either way if you can sell the client on the benefit . . . you take price out of the discussion anyway. Always within reason of course.
Is Salient the best VMS software out there today, most likely not . . . otherwise we couldn't afford it, lol. I'm sure that John H. is correct on his review, 2 years old or not . . . Salient hasn't changed that much, which has been a sticking point for many. But I can't let that take away from MY experience with the software, company, support, and our business' success in the Security Camera field.
Salient is worthy of consideration, and should not be thrown out as a BAD VMS solution.
**One last item worth mentioning: I love the fact that Salient can be installed on Hardware that I provide (Dell Servers for example). As an MSP, the technology side is where we live and die. So to be able to leverage one side of my organization to support the other (telecom / Security) has made a world of difference for us. I have NOT been a fan of the hardware that Salient provides, as I have found it to be under spec'd for our needs almost every time.
I hope this helps!
