Choosing between the V5 and K8 anti-cheat devices depends on the specific machine type and its vulnerability profile. A coverage map — a visual plan that assigns the appropriate device to each machine on your floor — ensures that every machine is protected against its primary threat without over-investing in protection that a particular machine does not need.
I have created coverage maps for 30+ venues. Here is the framework I use to match devices to machines.
When to Use the V5 Anti-Theft Dog
The V5 device is designed for machines whose primary threat is result-leak cheating through the display signal line, printer communication line, or RF emissions. The V5 is the right choice for: top ball machines (where the sensor harness is vulnerable), standalone lottery machines (no network connection, limited data ports), ball-drop redemption machines, and machines where the primary attack method is wireless signal interception within a 5-8 meter range.
When to Use the K8 Anti-Theft Dog
The K8 device is designed for machines with network connections, active data ports, or power line vulnerabilities. The K8 is the right choice for: networked lottery machines (connected to a central server), machines with accessible COM or USB ports, casino-style gaming terminals, and machines where the operator needs comprehensive protection across all five attack surfaces.
Creating Your Coverage Map
Walk your floor and create a list of every machine. For each machine, note: the machine type, whether it is networked, whether it has accessible data ports, the primary cheating threat based on the machine type, and whether a V5 or K8 device is appropriate. Then mark the placement of each V5 or K8 device on a floor plan, ensuring that the coverage zones (5-8 meters for V5, 5 meters for K8) overlap adequately to cover all machines.
If your arcade or game room is showing signs of uncertainty about V5 vs K8 device selection, send me a message with your machine model and a photo of your setup. I will do a quick remote check for free. Every device comes with a money-back guarantee, official invoice, express shipping, and 1-on-1 technical support.

Frequently Asked Questions
Q: Can I use the V5 and K8 devices interchangeably on the same machine type?
A: No. Each device is designed for a specific threat profile. Using the wrong device leaves some attack surfaces unprotected.
Q: How often should I update my coverage map?
A: Update the map whenever you change your machine layout or add new machine types. Review the map quarterly to ensure it still matches your current floor configuration.
Q: Can I start with a partial coverage map and expand later?
A: Yes. Start with your highest-revenue machines and add devices to other machines in subsequent phases. The coverage map helps you plan the expansion.
Q: Do I need a coverage map for a small venue with only 5-10 machines?
A: A formal map is less critical for small venues, but the same decision framework applies. Identify each machine’s primary threat and choose the appropriate device.
