Mini Spy Voice Recorder for Covert Recording, Long Battery Life, Rechargeable
You need to capture a conversation, meeting, or interaction, and you cannot risk being seen holding a recording device. Most voice recorders on the market either look obviously like a recorder, run out of storage fast, or die in the middle of a session because of weak battery life. That is the real problem people run into. The moment a recorder is spotted, or the moment it shuts off early, the entire purpose of using it is gone.
The Voice Activated Recorder solves this a different way. Instead of relying on you to hold it, hide it in a bag, or remember to hit record, it has a built in flat magnet on the back that lets you stick it to almost any metal surface in seconds. Slide it under a desk, attach it inside a car door panel, stick it to the back of a filing cabinet, or mount it under a conference table, then walk away. The unit is roughly the size of a roll of dimes, so once it is placed it becomes part of the furniture. Combine that with 250 hours of continuous recording on a single charge and 32GB of onboard storage, and you get a device that can sit in place recording for over ten straight days without you needing to check on it, swap batteries, or come back and reposition it.
The voice activated recording (VOR) feature also means it is not wasting storage or battery on silence. It automatically starts recording the moment it detects sound and stops when the room goes quiet, so a single charge and a single memory card can cover far more real conversation time than a standard continuous recorder. The indicator light shuts off completely once recording begins, so there is no blinking light to give it away.
This is not just a recorder you carry. It is a recorder you place and forget, built for situations where discretion and endurance matter more than anything else.
The recorder can be easily operated with one slider switch for recording and a line control for playback. Playback is operated by earphone with line control, which makes the operation much easier. Buttons let you start, stop, save, skip to the previous or next file, and pause the recording.
Voice activation can be turned on or off in software when the unit is connected to your computer.
The digital recorder can catch normal spoken voice up to 20 feet away, so you get fewer silent gaps in your recordings and get more out of the device's memory and your listening time.

Frequently Asked Questions:
Is it legal to use a voice activated recorder to record someone? Recording laws vary by state and country, including single party and two party consent rules. It is the responsibility of the user to research and follow all applicable local, state, and federal laws before recording any conversation.
How long does the battery last on a full charge? The Q70 offers up to 250 hours of continuous recording at 512 Kbps on a single charge, thanks to its built in 2500mAh battery.
How much can the Q70 actually record before running out of storage? With 32GB of storage, the Q70 can hold hundreds of hours of audio depending on the bitrate setting used, and it supports up to 999 files per folder.
Does the recorder have a visible light while recording? No. The light flashes briefly at startup to confirm the unit is on, then turns off completely during recording for total discretion.
What does voice activated recording (VOR) actually do? VOR automatically starts recording when it detects sound and stops when there is silence, which saves battery and storage compared to continuous recording.
How do I get the audio files off the device? Connect the Q70 to a computer via USB while it is powered off. It mounts as a removable disk, and you can drag and drop the audio files directly.
Can the magnetic mount damage a surface or fall off easily? The built in magnet is designed for a secure hold on metal surfaces and will not damage most surfaces, but it should be tested on your specific mounting location before relying on it for an extended period.
What is the best bitrate setting for recording voices? 192 Kbps is generally recommended for clear speech with efficient file size and battery use. 512 Kbps is the default setting and is better if you plan to edit the audio or need extra clarity for faint or distant voices.
How small is the Q70 and how easy is it to hide? It measures about 2.5 inches long, 1.2 inches wide, and 3/4 inch thick, roughly the size of a roll of dimes, making it easy to conceal or mount out of sight.
Does it come ready to use out of the box? Yes. When purchased directly from Surveillance Plus, the Q70 arrives fully charged, pre tested, with the time and date set, and voice activated recording already enabled.
