The short version

  • Only Keil MDK has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keil MDK pricing for Essential and Professional subscriptions not disclosed on primary site; VIVOTEK VAST Security Station vAST 2 has entered end of maintenance with technical support and software files withdrawn, yet distributors still list VAST 2 licences, so a buyer can be quoted unsupported software without realising it.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Keil MDK

  • Pricing for Essential and Professional subscriptions not disclosed on primary site
  • Customers must contact Arm Developer Tools store for subscription rates

VIVOTEK VAST Security Station

  • VAST 2 has entered end of maintenance with technical support and software files withdrawn, yet distributors still list VAST 2 licences, so a buyer can be quoted unsupported software without realising it.
  • The free Lite tier is hard capped at 32 cameras and VIVOTEK devices only, so a site that grows to 33 cameras or adds one third-party camera moves straight to paid Standard licensing.
  • VSS Professional includes no camera licences at all, so the edition that large deployments need starts from a higher effective price than the tier comparison suggests.
  • It is a camera manufacturer's VMS, so the third-party device list, analytics ecosystem and integration catalogue are all narrower than an independent platform like Milestone or Salient.
  • No pricing is published for Standard or Professional channels; everything runs through distribution, which makes budgeting a phased expansion difficult without repeated quotes.
