It can range from less than $100 per unit for very simple and low cost devices, to over $1,000 per unit for more complex solutions.
If the hardware is available off-the-shelf, we can purchase it for you at a nominal mark-up (typically 10%).
Our business is in developing customized solutions, not hardware trading, so you can also choose to purchase the hardware yourself.
