You have to have a different subfolder value for categories and for products, so they both cannot be surveillance-equipment. You should change one (perhaps for example change $cdseo_prod to surveillance-products) in your cdseo_config.php file and then update your .htaccess as follows:

DirectoryIndex home.php index.html index.php
RewriteEngine On
RewriteRule ^surveillance-equipment/(.*)$ home.php [L]
RewriteRule ^surveillance-products/(.*)$ product.php [L]
