MSAI Multisensor AI Cameras now a self funding SaaS model?

I have come across an interesting stock MSAI, previously known as ICI in the business for 30 years, without causing a dent in any industry, however something has changed over the last year with regards to their product (camera installs going up every quarter). what I see here is a self-funded SAAS model going forwards and I wondered what the community thoughts are on it? My thesis is this: MSAI makes about $4k-$5k profit per camera they sell, possibly $1k more with the install. Once installed each camera generates a yearly sub fee of between $3500 - $4000 per camera. Their cameras monitor things like conveyor belt systems, data centre components and various infrastructure that you might find inside a utility provider. Extrapolating these numbers up, MSAI would only need about 20,000 - 30,000 cameras installed to hit a MC of $1B on the SaaS revenue alone. 20,000 - 30,000 cameras is not a wild number tbh, unless somebody can provide further insight. The profits from these camera sales - circa $100M would surely prevent the need for any further dilution and fund production of more cameras too. Am I missing something or is that the business model in a nutshell subject to having an effective sales team and good execution?
