Wat maakt dit de kleinste gsm zender?

Met een afmeting van slechts 35 x 17 x 10 mm is dit één van de meest compacte modellen op de markt. Hierdoor is de zender zeer eenvoudig te verstoppen.

Hoe werkt het meeluisteren?

U plaatst een simkaart in het apparaat en belt naar dat nummer. De zender neemt automatisch op en activeert de microfoon voor directe live audio.

Hoe lang werkt de batterij?

De zender blijft tot 3 dagen stand-by en werkt ongeveer 1,5 uur bij actief gebruik. Voor langer gebruik is aansluiten op netstroom mogelijk (niet aangeraden voor permanent gebruik).

Is het geschikt voor langdurige inzet?

Vanwege de kleine batterij is dit model vooral geschikt voor korte en snelle observaties. Voor langdurige inzet zijn grotere modellen met langere accuduur beter geschikt.

Ja, met onze optionele telefoonrecorder (SKU 7004) kunt u tijdens het meeluisteren de gesprekken opnemen op uw eigen toestel.

This GSM listening device is ideal for short-term observations or temporary surveillance in the home, vehicle or office (always use in accordance with privacy legislation).

Operation via the mobile voice network

You insert a SIM card with call minutes, charge the device, and dial the number on the SIM card: the module automatically answers (without an audible click) and immediately activates the microphone for live audio. No internet or app is required—the connection is purely via voice calls (2G/3G/4G, depending on coverage and provider).
