Wireless Cameras Aren’t as Secure as You Might Think

There are many reasons individuals choose to implement wireless cameras. One of the most common reasons people use wireless cameras is as part of a nanny cam system. Many parents feel that a nanny cam is the only way to be completely sure that their children are safe and happy at home when they are away at work.


Others use cameras in their homes as a means of surveillance. Wireless cameras in conjunction with an alarm system can protect your property from intruders. Still others use cameras in their places of business. Some small business owners like to monitor their employees in order to make sure that everyone is working hard and not using company time to deal with personal business. Whatever your reason for using wireless cameras, you should understand just how secure these cameras really are.

How Wireless Cameras Work

Wireless cameras transmit recorded images as either analog or digital signals. The camera sends the images to your control system, where you can view and save them on a computer, phone or TV. The security of these cameras depends on the security of the network over which the camera sends the signal.

Wireless Cameras that Are Not Secure

Any wireless camera that transmits recorded footage over radio frequencies is not secure. These cameras record analog video, which can only be stored on a VCR and viewed on a closed circuit TV. There is no signal encryption of any kind with these types of cameras, and hackers can easily obtain the footage if they choose to target it. However, most cameras in recent years do not transmit analog signals over radio waves.

Secure Wireless Cameras

Most new security cameras send digital video over the internet via a wireless router. These cameras are also referred to as Wi-Fi cameras. They are much more expensive than cameras that use an analog signal, but they are much better in many ways. First, Wi-Fi cameras allow you to view, record and send images anywhere in the world. Second, they are much more secure from hackers. Footage sent over the internet is encrypted. This means that the data your camera sends to your control center is scrambled before transmission and then put back together again upon arrival. This type of encrypted transmission makes it virtually impossible for hackers to access your video footage.

Again, most of the best wireless cameras use this technology to send video. For instance, our top-three cameras, the DVRMDC Alarm Clock by Streetwise Security Systems, the SVAT PI-300 SD Alarm Clock by SVAT Electronics and the SVAT PI1000 Recording System, also by SVAT Electronics, all use Wi-Fi technology to send digital video. Most other cameras made within the last couple of years also use wireless routers to send digital video, meaning that hackers can’t touch the video these cameras send over the internet.

What to Look for in a Camera

You certainly want to get a wireless camera that uses Wi-Fi technology to keep your footage safe. However, since most cameras nowadays are manufactured with this technology, the price of these cameras continues to drop. The best wireless cameras also include features such as long battery life, a large memory for storing all your videos and motion detection, which saves you from fast forwarding through hours of empty footage since recording is triggered by motion and ends when the motion ceases.
