Ping is a simple network tool that checks if one device can reach another over a network. It sends a small data packet to a target IP address and waits for a reply to measure the response time.
In video surveillance, technicians often use ping to confirm that a camera or device remains connected. For example, if a camera stops working, a failed ping can indicate a network issue.
Quick ping tests help identify connection problems without using advanced diagnostic tools. Because of this, ping remains a go-to method for basic network troubleshooting.
Fast ping responses suggest a healthy connection, while long delays or no reply often point to network failures.
