Jerry C5 is a Clip-On Thermal Imager (COTI) from InfiRay Outdoor, one of the world's leading thermal makers. Snap it onto the objective lens of your existing night-vision device (such as the PVS-14) and it overlays a thermal image onto your night-vision view, instantly delivering true "fusion" — NV and thermal merged into a single field of view. No modification to the NVD itself is required.
🌟 Features & Capabilities
- Spot heat in an instant: Immediately detects the body heat of people or animals lurking in the dark. Targets that blend into the background flare up as bright thermal signatures, and the high-resolution 640×512 / 12μm sensor renders heat sources crisply even at night, through vegetation, or in poor weather (detection range varies by target and conditions).
- Cut through vegetation and bad weather: In conditions that are hard to see through — brush, smoke, fog, total darkness — heat is far harder to mask. From pitch black to bad weather to dense terrain, you gain situational awareness that visible or low light alone simply can't reach.
- Add thermal to your NVD without modifying it: Because it clips on, you bolt heat-detection capability onto your existing night-vision device with no machining or disassembly. Choose from three modes — Outline / Patrol / Full Thermal — to match the view to the task.

Where This Unit Fits
This unit is two tools in one. On its own it works as a thermal monocular for detecting human heat signatures; snap it onto your existing night-vision device (PVS-14 compatible) and you instantly upgrade to fusion viewing, overlaying thermal onto the NV image.
Turn the NVD you already own into your most capable detection device: Because this is a clip-on, you add heat-detection capability with no modification whatsoever to the NVD itself. For fusion use, please have a night-vision device such as the PVS-14 ready (compatible with DTNVS / Katana / RNVG / Sentinel / PVS-7, etc.).
🔋 About the Battery
