MVS Systems Inc

Pricing is very reasonable and they were able to use our existing service.  The day of install went fine, but I agree with the other reviewer's comments about lack of responsiveness.  It took a long time to get in touch with the salesperson and we really had to work to move the install along.  I may or may not continue using them, but I would look hard at other companies as well...  The good thing about this company is... no contract!

We got the name of MVS from Angie's list. There was one review and it
was positive.  During the process of purchasing the  DSC (brand) system
from MVS, we were told by the sales person (who eventually installed the
system) that there had been a lot of advancement in technology and the
new systems were much better, easier and allow for more control than our
17 year old Caddix Security system  which had started to have
problems.  The Caddix was a great system and the company who installed
it offered prompt response to any questions or repairs for 17 years. 
They were somewhat expensive though and we decided to try MVS.
My wife told the sales person from MVS a brighter, more easy to read
display and being easy to use and adjust were important factors for us. 
When the system was installed, the installer told us our old Caddix
keypads could be sold on Ebay for as much as a $100 a piece. He
suggested he take the three keypads and test them at his house to make
all three worked and then he would drop them back by to us.  Their store
front is very close.  We thought that was very nice of him to check
them for us.  The salesman/installer was pleasant but seemed primarily
familiar with just one DSC model rather than other choices available. 
We ended up upgrading to get a display with English read out which is
what we had before. 
Our first evening with the system was
disappointing. We realized the display was no brighter or even as easy
to read as the Caddix. The volume of the chime was much lower than our
prior Caddix system and too low to hear except when in the vicinity of
one of the pads.  Although the tone of the chime could be adjusted
roughly 20 ways, we could find no way to adjust the volume (which is
much more important).  We attempted later that afternoon to call the sales
person/installer for help on the cell number he left for us to contact him.  We
made several attempts to contact him, leaving messages over the next
week.   When he did not respond to the messages, we started to try to
catch him by calling the store and finally reached him about a week
later.  He said he would check the installation manual to see if there
was a way to adjust the  volume and get back to us. He said he knew we
could add a separate chime unit if the volume of the pads could not be
adjusted.  He also said he had not had a chance to check the old
keypads.  He promised to get back to us.
 
After a few more weeks going into  middle/late June, my wife contacted him at the
retail location and he said he was really busy and had not had a chance to
check whether the volume could be adjustable.  He did mention possibly
getting a separate chime to add to the system but did not know the price
to add it.  He said he had our old keypads at his desk but had been not
checked them out yet.   He promised to get back to us as soon as he
could.  On July 3rd, I called the store and the individual who installed
the system was not there. I talked to a woman at the store and
explained the situation.  She apologized and said she would see him the
next day on the 4th and would make sure he got back to us. We waited but
never heard any response.
I made one attempt in late July to reach the employee who installed the unit. He was not in
at the time and I never heard back from him.   In early September, we received our
first quarterly alarm monitoring bill which was in excess of the amount
agreed to.  My wife got a hold of the lady at the MVS store I had
previously talked to and she said she would correct the bill.  My wife
explained the situation saying we had never heard back from the
installer.  She also requested the keypads just be returned to us at this
point.  She promised to follow up with the salesman/installer and make
sure he got back to us.  She did correct the monitoring billing but we
never heard back from MVS.
At this point, over 4 months after
the install, we assume we will never hear back from the MVS and that
they just are not going to follow up with us on our concerns.  We
emailed a distributor of DSC about configuring the keypads for
additional volume but never heard back from them.

I give him an "A" overall and I would use him again in the future.
