The short version

  • Each has a real cost: Samotics sAM4 only sees what reaches the motor electrically, so it covers the driven train and misses un-driven equipment, structures, process conditions and anything downstream of a mechanical decoupling.; VTScada licences are per installed PC rather than per system, so a redundant pair plus a development machine means paying three times unless you buy the discounted multi-server bundles.
  • They diverge on capability: Samotics covers Electrical signature analysis, VTScada covers Automatic version control.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Samotics

  • A water utility monitoring submersible and borehole pumps that no vibration sensor can be fitted to without lifting the pumpnot VTScada
  • A chemical plant with assets in ATEX zones where certifying and maintaining in-field sensors is more expensive than the monitoring itselfnot VTScada
  • A food plant that wants pump and mixer condition data without opening guarding or taking a hygiene-critical line down to fit sensorsnot VTScada
  • A site building an energy reduction case, where measured motor efficiency and waste give the business case a payback that reliability alone would notnot VTScada

VTScada

  • A municipal water authority with 60 remote pump stations on licensed radio that needs DNP3 polling and regulator-facing change recordsnot Samotics
  • An oil and gas gathering operator polling wellsite RTUs over intermittent cellular links with store and forwardnot Samotics
  • A small utility that must produce a defensible budget number before going to council for capital approvalnot Samotics
  • An integrator standardising on one product where historian, alarming and dialler costs are inside the licence rather than quoted separatelynot Samotics

Where each one falls short

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

Samotics

  • SAM4 only sees what reaches the motor electrically, so it covers the driven train and misses un-driven equipment, structures, process conditions and anything downstream of a mechanical decoupling.
  • Each monitored motor needs hardware installed in the motor control centre by a qualified electrician, and in older switchrooms that installation, including any required outage, can cost more than a year of the subscription.
  • Per-asset subscription pricing means the cost scales linearly with the number of motors, so a plant with a thousand small motors faces a bill that a fixed-price plant-wide vibration system would not impose.
  • Electrical signature analysis on variable-speed drives is harder than on direct-on-line motors, and results vary with drive type, so a heavily VSD estate should insist on a pilot on its own drives before committing.
  • Nothing is published on price, contract length or minimum deployment size, and the vendor sells multi-year subscriptions, so early exit terms are a negotiation you have to raise yourself.

VTScada

  • Licences are per installed PC rather than per system, so a redundant pair plus a development machine means paying three times unless you buy the discounted multi-server bundles.
  • Thin client licensing is by concurrent connection and is priced steeply at scale: unlimited thin clients on a 50,000 tag system costs 59,395 USD on top of the base licence, more than the base licence itself.
  • It is Windows only with no Linux or container deployment, which rules it out of modern edge and virtualised architectures that other SCADA products now support.
  • SupportPlus at 15 percent of the original software price must be maintained continuously; if you let it lapse you cannot simply resume, and reinstatement is negotiated rather than published.
  • The scripting environment and the integrator pool are both proprietary and small, so finding a second-source integrator in a region where Trihedral has thin coverage is genuinely difficult.

Questions people ask

Is Samotics or VTScada better?
Neither clearly leads. Samotics starts at On request and VTScada at $3395/one-time, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Samotics or VTScada?
Samotics starts at On request and VTScada at $3395/one-time.
Does Samotics or VTScada run on more platforms?
Samotics runs on Web, Cloud. VTScada runs on Windows.
What is Samotics best used for?
Samotics is most often used for a water utility monitoring submersible and borehole pumps that no vibration sensor can be fitted to without lifting the pump, a chemical plant with assets in atex zones where certifying and maintaining in-field sensors is more expensive than the monitoring itself, a food plant that wants pump and mixer condition data without opening guarding or taking a hygiene-critical line down to fit sensors, a site building an energy reduction case, where measured motor efficiency and waste give the business case a payback that reliability alone would not. Of those, a water utility monitoring submersible and borehole pumps that no vibration sensor can be fitted to without lifting the pump and a chemical plant with assets in atex zones where certifying and maintaining in-field sensors is more expensive than the monitoring itself are not what VTScada is typically brought in for.
What can Samotics do that VTScada cannot?
Samotics covers Electrical signature analysis, Switchroom installation, Energy and efficiency measurement, Submersible and hazardous area coverage. VTScada covers Automatic version control, Bundled historian, Alarm notification, Driver set included.

Answered from the vendors’ own pages

Samotics: Does Samotics replace vibration monitoring?

For motor-driven assets it often does, and it reaches assets vibration cannot. For un-driven equipment and structures it does not apply at all.

VTScada: Is VTScada perpetual or subscription?

Perpetual. Licences are one-time purchases per installed PC, with an optional annual SupportPlus contract at 15 percent of the original software price.

Samotics: Do I have to buy Samotics hardware?

Yes. SAM4 requires the vendor's sensors fitted in the motor control centre; there is no software-only option.

VTScada: Are drivers extra?

No. Standard and proprietary I/O drivers, the historian, trending, reporting and security are all included in the base licence.

Samotics: Does it work on variable-speed drives?

It can, but performance depends on the drive and the operating profile. Pilot it on your own VSD assets rather than accepting a reference from a direct-on-line site.

VTScada: What does support actually cost?

Annual SupportPlus is 15 percent of total software purchase price. Adding 24/7 emergency support is a further 5 percent with a 1,540 USD minimum.

Samotics: How is it priced?

Subscription per monitored asset, quoted, typically on a multi-year term, with hardware and electrical installation on top.

VTScada: Does it run on Linux?

No. VTScada is Windows only.
