Having trouble with keywords for niche product

Hi, I am new to this forum and SEO.
I am currently in the process of performing keyword research for best positioning of pages on my new site. The trouble is, I am having trouble finding any keywords that have significant volume and not sure if the product is so niche that not many people are searching for it or whether I have not identified the keywords the target customers are really using in their searches.
My product is a Pedestrian detection and warning system for vehicles. It is used to reduce risk of collision between vehicles and people. The keywords I have been looking at are Proximity Warning systems, proximity detection, proximity alert, collision avoidance, pedestrian safety, forklift proximity detection etc but these only reveal a small number of search results and some are so low Google Keyword planner show average volume = 0.
I am looking for any constructive ideas for honing in on more appropriate keywords or to understand how I could use what is available from these keywords to put t use.
I have watched several SEO videos and they all use very popular topics like hiking in California or iphone cases that have thousands of keyword options with hundred's of thousands of searches.

 

If you don't find the best keywords for your business then try to catch those keywords that your competitors are using.

Suppose, you keyword is “Proximity Warning systems”, go to Google and search with this keyword. Now it’ll show your competitors website that already ranked for this keyword. Pick one of the direct competitors like “personal protective equipment ppe” Monthly search value 720, CPC $1.82 that’s pretty much good keywords for your niche.



Finally, pick some good keywords for your business and make your business strategies to rank for those keywords.

 

HELLO
first u need to search the keyword difficulty below 40, goggle trends, average monthly value below 5000 and all in title below 50.

if u couldnt find out no monthly search value then u should not go for this niche , because if there is no search value how can u work with it. ya u can use paid tool long tail pro and google keyword planner tool.

whatever u search just keep in mind there should be search value and u can try different LSI version.

thank u
