- When does FNIRSI run sales?
- FNIRSI discounts most heavily around Singles' Day (November 11), Black Friday and Chinese New Year. Its own store and AliExpress listings also drop during mid-year platform sales in June and July. Outside those windows, prices on the NVS-20 4K tend to sit flat.
- Where is the FNIRSI NVS-20 4K cheapest?
- It is usually cheapest on AliExpress or FNIRSI's own store, with Amazon and eBay resellers charging more for faster shipping and easier returns. Check the price history on this page before buying, since reseller prices swing widely between sellers.
- What is FNIRSI best known for?
- FNIRSI built its reputation on cheap handheld oscilloscopes such as the DSO-TC3 and 2C53T, plus the SG-004A signal generator. Its night vision and thermal monoculars are a newer line, and the NVS-20 4K is its 4K-recording digital night vision model.
- What is the return policy on FNIRSI products?
- Returns depend on the seller, not FNIRSI itself. FNIRSI's own store typically allows returns within 7 to 15 days of delivery if the item is unused and in its original packaging, while Amazon and eBay orders follow that marketplace's window.
- Does the NVS-20 4K record video?
- Yes. It records 4K video and takes stills to a microSD card, and it has a built-in IR illuminator for use in complete darkness. Its sensor is a digital CMOS unit, so image quality at long range is below that of Gen 2+ analog night vision.
- Are there FNIRSI discount codes?
- Deal.ai doesn't list FNIRSI discount codes. It checks what FNIRSI products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
