Computer Network Design and Management
Smart, secure, and scalable networks for your home or businesses
Why your network matters
Your network is the backbone of daily operations — powering point-of-sale systems, phones, surveillance, cloud backups, and employee productivity. A poorly designed or unmanaged network leads to downtime, security gaps, slow performance, and lost revenue. Crossley Media builds networks that are resilient, secure, and easy to manage.

FAQs
Do you test cabling after installation? Yes — every cable is tested and results recorded with our Fluke Networks tester. You will get a copy of the report after the project is closed.
Can you manage our existing equipment? Absolutely. We support most major vendors and can integrate with your current hardware or recommend phased upgrades.
How quickly can you provide cellular failover? We can deploy managed cellular backup as part of a new install or add it to an existing site — typically configured and tested within a planned maintenance window. We would need to complete a site survey first, in order to recommend the best hardware for your use case.
