General Pricing FAQs

What happens when I exceed the monthly number of lookups?

We inform you on the number of Plate Lookups used in our SDK and Cloud API.  This way, you can upgrade to a higher plan whenever the current plan is about to reach its limit.  The number of Plate Lookups will be limited to the selected plan for each month.

Can I upgrade, downgrade or cancel my plan at any time?


A lookup is basically any image that is sent over to the API Cloud or SDK.  Even if that image does not contain a vehicle plate, it is still counted as a lookup.  One lookup may have multiple vehicles in the image.

Is there a limit on Plate Lookups Per Second for Cloud API?

For Cloud API, there is a maximum of 2 Plate Lookups per second.  If more is needed, please Contact Us for a custom quote.

Subscription SDK Pricing FAQs

Does SDK require Internet access?

Our ALPR SDK requires Internet access during the set up process.  The Subscription SDK License requires Internet one every 30 days so that we can ensure that the License Key is still valid.  If your environment does not have Internet access, then you’ll need the Perpetual SDK License.

Is there a free trial available with the SDK?

Not at this time.  The code to use our Cloud API is identical to that of our On-Premise SDK.  We encourage users who are evaluating Plate Recognizer to first start with the free trial via our API Cloud.

Is the Annual SDK Maintenance included with my Subscription SDK License?

Yes! The Annual SDK Maintenance is included in your Subscription SDK License.

Can I change my Subscription SDK License to a new machine?

Yes!  For the Subscription SDK License, you can use the original, existing SDK license key on a new machine.  So in the event that the original machine has crashed, you can transfer the SDK license key to another machine.

Perpetual SDK Pricing FAQs

Does Perpetual SDK License require Internet access?

After the initial installation, the Perpetual SDK License does not require Internet access.  Only the Subscription SDK License requires some Internet access.

Can I get a perpetual license for On-Premise SDK?

Yes!  Please contact us for more information.

Is the Annual SDK Maintenance included with my Perpetual SDK License?

No.  The Annual SDK Maintenance is purchased separately from the Perpetual SDK License.

What happens to my Perpetual SDK License when my machine crashes?

For a Perpetual SDK License, if the machine is not able to connect to the Internet and uninstall the existing SDK onboard, then there is no way for us to determine that the original SDK was removed. In this situation, unfortunately, you will have to purchase a new SDK license. 

Can I change my Perpetual SDK License to another machine?

If you have the Annual SDK Maintenance, then yes, you can uninstall and reinstall the Perpetual SDK License onto a different machine.  This effort requires Internet access for the uninstallation and reinstallation process. 

Annual Maintenance Pricing FAQs

What is the Annual SDK Maintenance?

Annual SDK Maintenance applies only to Perpetual SDK licenses (not to those on SDK subscription).  The annual SDK Maintenance is 20% of software purchase price and is paid upfront for the year. With Annual SDK Maintenance, you get ongoing software updates and the ability to uninstall the On Premise SDK and install it on a different machine under the same license key.  This requires Internet access for the On Premise SDK. 

How is the Annual SDK Maintenance calculated?

The Annual SDK Maintenance cost is calculated as 20% of the purchased price of the Perpetual SDK license.
