You're asking the right question. CCTV cameras are an invaluable tool for maintaining security, but their effectiveness is very dependent on the quality of the cameras and where they are placed.
First and foremost, you need to consider the purpose of your cameras. Are you looking to monitor a specific area, prevent theft or vandalism, or simply keep a watchful eye on your property? Depending on your needs, you'll want to select cameras with specific features like high resolution, wide-angle views, and night vision capabilities.
Another important factor to consider is the location of your cameras. You'll want to position your cameras in areas that are most vulnerable to security breaches, such as entry points, parking lots, and storage areas.
This is all stuff a good construction security company can help you with, by the way. As the Derbyshire section of this website shows: https://www.ribersecurity.co.uk/Security-Debyshire-Chesterfield.htm. So, if you're planning on outsourcing security, it's smart to let your contractors choose the cameras.
Finally, it's important to have a plan in place for storing the footage captured by your cameras. Will you store the footage on-site or in the cloud? What is the storage capacity, and how long will the footage be retained? Planning ahead here usually costs less than solving the problem later.
