A successful PTZ installation isn’t just about choosing the right equipment—it’s about getting the configuration right before leaving the site.
These three DDA analytics checks can make a real difference: fewer false alerts, better detection and, importantly, fewer callbacks.
A useful commissioning reminder for every security installer working with PTZ analytics. Well worth saving and sharing with your technical team.
Before you commission that PTZ, here's the DDA analytics config most installers skip, and why it costs them callbacks.
Misconfigured DDA analytics is one of the quiet reasons a PTZ deployment gets a return visit.
The Z4-25IPEN-4(IR) has the built-in analytics to get it right on the first pass. You just need to check the right settings before sign-off.
🔧 DDA Analytics: 3 settings to check before you leave site
✅ Detection zones: confirm your rules are mapped to the areas that actually matter, not the full frame
✅ Object filtering: set the minimum and maximum target size so vehicles and people trigger correctly and false alerts drop off
✅ Tour and preset alignment: make sure your analytics stay active across PTZ movements, not just the home position
Get these three locked in during commissioning and you cut the callbacks that come from alerts firing on the wrong thing, or not firing at all.
📦 The Z4-25IPEN-4(IR) is available now at Security Wholesale Limited.
