milerpip - Ask what cameras are in other companies and which company should contact on this issue.

rebeccakerr - "It all depends on the company you contact. Some companies make cameras themselves, and some outbid these products and pass them off as their own.
First, select two companies. Then compare their prices for various services. For example, this way, I chose https://paydaydeals.com.au/collections/cctv-security-cameras-systems . I was satisfied with all the prices they offered for their services. I also focused on reviews on the Internet. As it turned out, I couldn't find a single negative review.
I have been working with this company for about a year, and at the moment everything suits me."
