Description of the article « PRO29 4G Remote Audio Module with Nano SIM »
Where a site has no reliable Wi-Fi, a mobile-network audio connection can be useful for a specifically authorised monitoring requirement. The PRO29 uses an active Nano SIM and a compatible 4G service to make audio accessible from a telephone included on its permitted caller list.
The module supports up to five authorised phone numbers and a configurable sound-triggered return call. The quoted triggering threshold is around 40 dB, but background noise, placement and sensitivity settings can affect when an alert happens. It is not a voice recognition system and does not establish the identity of a person.
Before installing in a permitted setting, check reception at the exact location and confirm the SIM supports the necessary calls. Follow the PRO29 instructions for PIN settings and number authorisation. Test several sound events before relying on the return-call feature.
Unlike the PRO29 12 V vehicle edition or the mains-powered edition, the standard unit can be configured around a separate suitable battery supply. This is useful where there is no continuously available vehicle or building power source.
With a reference 2,500 mAh battery, quoted operation is up to approximately ten days on standby or about ten hours of continuous listening. Both estimates vary with coverage and the frequency of calls. A compatible 5 V USB supply is used for low-voltage power.
Remote audio access requires an active mobile service. In the UK, privacy, workplace monitoring and communications laws may apply, and ownership of a room does not automatically authorise listening to private conversations.
Network reception, the operator tariff and the configuration of authorised callers should be checked before the system is relied on. False alerts can arise from ordinary background noise.
A battery-powered module favours portable arrangements, a 12 V edition suits compatible vehicle power and a mains edition suits fixed installations. Selecting the right supply matters more than a marketing claim about maximum runtime.
In the UK, capturing other people's conversations may be unlawful without appropriate authority. Assess UK GDPR, data protection and any applicable communications or employment rules before use; never assume physical ownership alone permits listening.
No. It uses a compatible mobile network through an active Nano SIM.
Indicative figures are up to roughly ten days on standby and around ten hours of continuous listening.
Yes. The PRO29 instructions describe configuring up to five authorised telephone numbers.
