To choose a VMS, compare vendors on eight things: camera compatibility, data location and security, scalability, ease of use, recording and reliability, analytics, total cost of ownership and who takes part in the decision. Below is what to ask about each, how to score vendors and what to test in a demo.
BEFORE YOU COMPARE
A video management system sits between every camera you own and every person who needs to see what they record. You will run it for years, connect it to other systems and train every shift on it. Switching later can mean migrating footage, retraining staff and replacing hardware. That is why the questions below go past feature lists. Ask them of every vendor, including us.

THE 8 CRITERIA
01
An open VMS supports cameras from many manufacturers and open standards such as ONVIF. A closed one ties you to one hardware brand, so every future camera purchase is decided by your software vendor.
Ask the vendor:
Red flag: the demo only uses the vendor's own cameras, or "ONVIF support" is the only answer you get. Verify your exact camera models and firmware versions.
Mirasys supports 8,000+ camera models, including Axis, Bosch, Dahua, Hanwha, Hikvision and Pelco, and ONVIF Profiles G, S, T and M. See integrations →
02
Video of people is personal data. Where it is stored, which country's laws give access to it and who inside your organisation can see it matter for GDPR, and in many sectors they are a procurement requirement.
Ask the vendor:
Red flag: the answer to "where is our data" is a cloud region you cannot choose, or there is no log of who viewed or exported footage.
With Mirasys, footage stays under European jurisdiction. Access control includes two-factor authentication, and full audit trails show who did what. Security & compliance →
03
A VMS that is fine for one building can become hard to manage across ten. Check that many servers and sites run as one system, with one set of users and rules.
Ask the vendor:
Red flag: each new site needs its own separate installation and login.
Mirasys runs unlimited servers and cameras in one domain. It is deployed across every prison in Finland (RISE) and in Phuket City.
04
The most experienced operator is not always on duty. The interface has to be clear enough that other staff can find footage and react with little training.
Ask the vendor:
Red flag: the vendor's own engineer has to drive the whole demo.
In Mirasys, operators work in Spotter, the interface for live view, search, alarms and playback. About Spotter →
05
Cameras keep recording only if the system around them does. Check how the VMS records and stores video, and how it behaves when hardware or the network breaks, not only when everything works.
Ask the vendor:
Red flag: failover is "on the roadmap" or costs extra per camera.
Viking Line has used Mirasys for more than 10 years.
06
Analytics are only useful if operators trust them. Too many false alarms and people start ignoring alerts. The real test is how fast an investigator finds a past event.
Ask the vendor:
Red flag: analytics need a separate system with its own interface.
Mirasys AI runs inside the VMS: license plate recognition, facial recognition and object recognition.
07
License price is only part of the cost. Storage, yearly fees, required hardware and the work needed to add cameras add up over the system's life.
Ask the vendor:
Mirasys runs as software on your own infrastructure, as a ready-to-go appliance or as a hybrid. Try it free for 90 days. Get the trial →
08
A VMS touches IT, operations, maintenance, safety and the people who watch the screens every day. When they join late, requirements change after the contract is signed.
Ask yourselves:
In many European countries this is also a legal step. In Finland, for example, camera surveillance of a workplace is handled through the co-operation procedure with staff, and in Germany the works council has a say in technical monitoring of employees. Check the rules in your country and leave time for them in the schedule.
Red flag: the decision is made by one team and handed to the rest.

ALREADY HAVE A VMS?
Many buyers already have a system in place. The risk in changing is switching the old system off before the new one is proven.
Mirasys offers hybrid and migration setups for moving from an existing system.
Every camera with model and firmware, every integration, and how long footage must be kept.
Ask the new vendor to confirm each camera model before you sign.
Start with one site or one camera group while the old system keeps recording.
Train operators on each site as it moves, not all at once at the end.
Plan how recordings made in the old system can be viewed until their retention period ends.
SIZE OF THE SYSTEM
The number of cameras and sites decides how much VMS you need. Buying too little means replacing it as you grow. Buying too much means paying for complexity nobody uses.
DEPLOYMENT
The right setup depends on where your footage must stay and how much you rely on the internet connection.
IN THE DEMO
Give each vendor a score from 1 to 5 on every criterion during the demo and add them up. The highest total is your strongest candidate.
TEST BEFORE YOU BUY
Ask every shortlisted vendor to show these with your own camera models, not a prepared showroom setup.
