The short version

  • Each has a real cost: Halter the subscription is permanent and per head, so a 500 cow dairy carries a five-figure annual bill indefinitely and the collars become inert if it lapses; there is no owned-outright end state.; Sentera the offering bundles Sentera sensor hardware with the software, with hardware covered by separate Hardware and Services Addenda to the master agreement
  • They diverge on capability: Halter covers Virtual fencing, Sentera covers Multispectral imaging.
  • 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.

Halter

  • The subscription is permanent and per head, so a 500 cow dairy carries a five-figure annual bill indefinitely and the collars become inert if it lapses; there is no owned-outright end state.
  • On-farm tower infrastructure is a separate up-front install cost that is not in the headline per-cow price, and terrain with hills or bush can require more towers than the initial quote assumed.
  • Coverage is concentrated in New Zealand, Australia and parts of the United States; buyers elsewhere face no local support, no local install crew and uncertain regulatory acceptance of virtual fencing.
  • Virtual fencing is not universally legal or accepted: some jurisdictions and some organic or welfare certification schemes restrict aversive stimulus devices, which can decide eligibility before price is even discussed.
  • Total vendor lock-in on collar, towers, app and animal data means there is no second source for a replacement collar and no way to keep the fencing working if the commercial relationship ends.

Sentera

  • The offering bundles Sentera sensor hardware with the software, with hardware covered by separate Hardware and Services Addenda to the master agreement
  • No price, rate or minimum is published anywhere on the site

Answered from the vendors’ own pages

Halter: Do I buy the collars or rent them?

In practice you are buying into a per-cow monthly subscription plus a one-time install for the towers. The collars are not useful without an active subscription.

Sentera: How much does Sentera cost?

Sentera does not publish pricing on their website. The company describes solutions as scalable and affordable but requires direct contact for specific pricing. Customers can call 1-844-SENTERA or use the contact page.

Source
Halter: What does it actually cost for 500 cows?

Starting from around NZ$9.90 per cow per month, that is roughly NZ$59,000 a year before the one-time tower infrastructure cost, and it recurs every year.

Sentera: How can I get a Sentera pricing quote?

You can contact Sentera directly at 1-844-SENTERA or through their contact page. You can also log into FieldAgent or explore the product catalog and mission calculator for more information about specific offerings.

Source
Halter: Can I finance it?

New Zealand dairy farmers can finance the install through ANZ, ASB, BNZ or Westpac over two years, and paying the subscription up front attracts a discount.

Halter: Does it replace heat detection collars?

Yes on the higher tiers. That is the main reason dairies justify the cost, because it removes a second per-cow system.
