![]() ![]() In the US, 24 states outlaw the use of hidden cameras in private places.ģ8 states, including New York and Texas, follow the ‘one-party consent’ rule which allows for conversations to be recorded with one party’s consent, but without telling the other party. The laws regulating audio surveillance vary around the world and state-by-state. An example of an Ethernet cable from Amazon.Ĭonfused about what DVR is? Refresh your knowledge! Understanding the Laws Around Audio Recording An example of a digital audio-hybrid coaxial cable from Amazon. These are much thinner wires, and you’ll recognize these from your own broadband at home. On the other hand, Ethernet cables (see below), which can be used alongside NVRs, can transfer audio. Where ordinary coaxial cables are concerned, you can rest assured that audio isn’t being recorded. ![]() Hybrid coaxial cables are used for audio transfer (see below). An example of a coaxial cable from Amazon. These are thick and difficult to conceal, so you’ll usually notice them being fed inside the wall where a camera is recording. Most traditional CCTV uses coaxial cables (see below), which do not support native audio transfer. The wires, on the other hand, won’t be so easy to hide. After all, if hidden surveillance is the goal of the user, the microphone itself might be pretty well-concealed. Speaking of wires, another solid means of determining audio recording capabilities is to know what types of connections to look out for. If you spot something mounted that looks like a miniature smoke alarm with wires popping out of it, it’s an external mic. It may also appear as a kind of small stick at the end of a wire, which can be taped to the camera itself. The microphone will be much smaller, spherical or box shaped, and just a couple of inches in diameter. An example of a typical security camera external mic, available on Amazon. Hybrid connections can be used to facilitate it, but if the camera has no microphone built in, audio recording will have to be conducted separately. Often, conventional CCTV that interfaces with a DVR/NVR (the kind you’ll find in most public spaces) does not have native audio support. If a serial number is impossible to find, checking for external microphones is your next best bet if you want to find out if you’ve got a camera with audio recording on your hands. A quick search for the camera model should then reveal if it is a camera with audio recording. If the camera is mounted, this should be pretty easy to spot. You’ll find the camera’s serial number on a sticker, usually placed on the underside of the camera. ![]() The easiest way to find out if you’re being recorded or not is to turn to Google. In fact, they may not have any native audio functions whatsoever. Method 3: Serial NumberĬonventional security cameras with audio, like those used in public spaces, will prove more challenging to ascertain whether they can record or not, since they probably won’t have obvious features like speakers on them. This is because it’s easier for the camera to pick up audio if the microphone faces in the same direction as the lens (which faces the subject being recorded). A single hole which is the camera’s microphone is right above the lens. As mentioned, microphones aren’t always positioned in the same place as speakers, and more often than not you’ll find them on the front of the device near the lens. If there isn’t text printed next to it reading ‘reset’, this is guaranteed to be the camera’s microphone. If that’s the case, you can instead look out for a single hole smaller than a pinhead. Some speakers may be more subtle than others, or otherwise the camera in question is positioned so that it is impossible to see. Though the microphone itself isn’t always contained within this cluster of holes, it’s still a very strong indication that the camera has audio capabilities. But for the most part, you’ll find what looks like dozens of holes in a circular shape on the back of the device. Of course, the placement might vary, so look around if you can (it could be on the top or the underside of the device). IP cameras share similar design traits, and most cameras with audio will have an overt speaker on the back of the device. a consumer-grade security camera that functions via Wi-Fi). This visual check will be most useful if the camera in question is an IP camera (i.e. ![]() Understanding the Laws Around Audio Recording. ![]()
