What the numbers mean
Same lens length, different sensors. The XQ19 uses a 384×288 sensor with 17 µm pixels; the Taipan V2 uses 12 µm pixels. Smaller pixels mean each one covers a smaller angle, so the Taipan resolves the same animal farther away: 950 m of reach against 670 m by our formula. The bigger pixels give the XQ19 a wider 19.5° field against 13.8°.
Both are IP-rated for water (IPX7 for Pulsar, IP67 for AGM), both record and connect to an app. The Taipan has a sharper screen (1024×768 against 640×400) and two batteries in the box; the XQ19 is 249 g with its battery against about 355 g. Pulsar's warranty is 3 years, 5 with registration; AGM's is 5 years, transferable.
