Which DVTel version? Their high end one - Latitiude? You need all DVTel features?
Which specific features besides the few you list are critical? Many VMSes have good ONVIF support, server side VMD and client/server archicecture.
How many cameras do you want to support? What systems do you want to integrate with the VMS?
What is a 'not expensive price'? $50 per channel? $150 per channel? $250 per channel? Are annual maintenance fees a dealbreaker for you?
Yes I mean the Latitude.
Listing all the features here is too much but what I mean a feature set that can compete with milestone / genetc / avigilon like:
Support for dual stream.
timeline for all played back cameras
support for virtual matrix
hot backup for cameras
Audio and I/O support
support for unlimited number of users
the NVR should support multi servers while each server should support at least 64 cameras if not more.
A large system should support about 150-200 cameras.
License price should be around $100 to the installer.
Latitude Classic is sold here for less.
Even milestone sells the basic licenses for less but not as cheap as DVTel.
Wavestore sells for aroud than 100$ and Axxon too.
There ar also GeoVision and W4N but these are not well known.
I'm looking for a midsize system that can take a bite from the bigger ones.
