 Introducing the Ultra-Compact UHF Spy Bug!  (Spy-IL5)
Smaller than a coin. No Wi-Fi. No apps. No recording. Just pure live audio.

• Ultra-compact body: about 15 mm diameter and 5 mm thickness (with battery)
• Real-time listening: live audio transmission only (no internal recording)
• Strong range: up to 250–300 m line-of-sight in open area*
• Works with common UHF radios: compatible with 400–470 MHz walkie-talkie receivers (not included)

Spy-IL5 is an ultra-compact UHF radio microphone designed for discreet, real-time audio monitoring in controlled environments. The device transmits live audio to a compatible UHF receiver so you can listen instantly — no pairing apps, no Wi-Fi, no GSM, no recording.

The unit is factory-tuned around 420.00 MHz and uses a small hidden antenna (approx. 10 cm) for stable transmission. For best results, use a quality UHF handheld receiver and keep a clear line-of-sight when possible.

Power is provided by a standard CR1220 (3V) lithium battery (included). Typical operating time is 5–10 hours depending on conditions. Installation is simple — use the included double-sided tape to place the transmitter in a hard-to-reach area.
