Corporate Bug Sweeps

In the corporate world, trade secrets are what keep businesses alive. Discussions and office meetings with certain clients may be highly confidential and also highly valuable to other competitors. There are many ways for competitors to infiltrate business offices, and it is also fairly simple to deploy a listening or video recording device. They come in all shapes and sizes but more often than not, they are very discreet and very well hidden. Offices also come in all shapes and sizes, but generally the bigger the office is, the easier it is to deploy a device thus making it more difficult to locate. Smaller offices make things a little trickier for a deployment, but by no means impossible. There are still many nooks and cranny's to hide a tiny device, and it will still need a professional bug sweep to locate one. There are many comings and goings in most offices which makes it easy for someone to deploy a device undetected. That unsuspecting parcel delivery, that person who came in asking for directions or even that person who came in to deliver a convincing sales pitch... Any of these visits could have been pushed with sinister intentions and it a device could quite easily have been dropped off during them.

Is My House Bugged?

Although it is highly unlikely for an unwelcomed intruder to deploy a recording device in your personal property (although not unheard of), someone a bit closer to home who you have actually invited inside could have deployed such a device. Maybe a close friend, partner or even a family member. These things do happen for an endless list of reasons and you should check for your own peace of mind to protect your privacy. Most homes come with a number of different rooms and multiple places to hide a device in each room. With devices being so small these days, it is very easy to hide one in an unsuspecting place in your own home. As mentioned, your home does not necessarily need to be broken into to deploy a recording device. Your partner that you live with could have planted one, or your partner could have hired an investigator of his or her own and granted access while you were out shopping etc.  

Hiding Places

Although recording devices (bugs) are usually very small in size and can be hidden pretty much anywhere, they are more often than not deployed in a concealed manor and not visible to the naked eye. A bug does not need to have a clear line of sight or even need to be in close proximity to record audio (conversations) because the microphones installed in these devices are so sensitive that they can record clear audio even when packed away somewhere tucked away out of sight. Dependent on the type of device being used, as long as they can pick up the required signal (3G, 4G WiFi etc.) they will be effective. We have put together a list of common places bugs are deployed in offices and homes where you can see why a professional bug sweep carried out by a trained investigator should be considered.


This list is by no means exhaustive as there are many ways to conceal and hide a recording device in your home, office, vehicle or any other property. Most bug sweeps require specific frequency detecting equipment to locate hidden devices to avoid ripping up all the floor boards, or damaging walls and ceiling etc. We deploy trained operatives or even teams of operatives dependent on specifics of the sweep who are correctly kitted out for bug sweeps to avoid property damage, to locate hidden devices and to ultimately restore peace of mind. 

Ceiling Voids

Bug deployments in ceiling voids is a common place in office environments as the ceilings are generally made from lightweight tiles which can be raised to gain access. To person who deploys the device will pretty much have access to the entire ceiling void making in very difficult for an untrained and unequipped investigator to locate it.

Plug Sockets

Plug sockets are very discreet places to hide small bugs as they generally require a screwdriver to gain access to them. Homes and offices have multiple sockets on all floors again making it difficult for an untrained and unequipped investigator to locate a hidden device.

Floor Boards

Under the floor boards is a perfect place to deploy a listening device. Rolling a corner of carpet up and lifting a single floor board to drop in a device is a straight forward job however it could create some disturbance and sign that something has happened in the specific area of the room if not carried out correctly.

Recording Device Hiding Places

Book Shelves

Recording devices are not always necessarily small in size. Sometimes, and we are seeing a lot more devices now being disguised as every-day items. A book on a book shelf could have a camera fitted to the spine. Alarm clocks are now being manufactured with a camera lens installed behind the clock face. DAB radios can be made to look and operate like normal DAB radios, but actually they have tiny cameras and microphones installed to monitor rooms. These every-day items that can be placed on a book shelf are becoming more and more common. They are often used as a form of security, but they are also used for the more sinister intentions as well.

Using furniture to conceal a bug is typically a hasty way of doing things for the person who deploys it, and it can leave the bug exposed to the naked eye. Deploying the bug under a desk or under a chair for example would define the bug as concealed, but it only requires a quick look under such places to locate the device. A bug could however be deployed inside a sofa for example which would make things a bit more difficult for an investigator when conducting a sweep, but certainly not impossible.

Fire Alarms

Much like the every-day items as previously mentioned, bugs are now being purposely built into the fire or smoke alarms. It will be quite simple to remove an existing alarm and replace it with bugged one without you even noticing it.
