More consumers are starting to install wireless security systems as easy means of surveillance for their home and business. One of the most common reasons people use wireless cameras is as part of a nanny cam system. Many parents feel that nanny cams are the only way to be completely sure that their children are safe and happy at home when they are away at work. Others use wireless cameras in their business to monitor their employee’s productivity and safety. Wireless cameras offer a few benefits like easy installation and configuration; however their flaws can lead to a critical security breach. Using complex cyber security tools, criminals can identify unsecured connections and are now able to watch everything going on in your home / business. We would like to use this article to inform about some critical security steps to secure your wireless network if you choose that route.
Any wireless camera that transmits recorded footage over radio frequencies is not secure. These cameras record analog video, which can be stored on a DVR and viewed on a closed circuit TV. These cameras do not offer any signal encryptions, which leaves your system vulnerable to somebody interfering and capturing the recordings. Although this is a major concern for older technology, most cameras in recent years do not transmit analog signals over radio waves. Most new security cameras send digital video over the internet via a wireless router. These cameras are also referred to asWi-FI cameras. They are much more expensive than cameras that use an analog signal, but they are much better in many ways as long as they are used under the correct security measures.According to a ComputerWorld security report, 20 percent of all security cameras still use out-of-the-box settings: "admin" as a username and no password whatsoever. Leaving your connection unsecured is a major security issue and should not be ignored. Unauthorized attackers can access the entire file system and steal Web & Wi-Fi credentials and gain access to whatever video / audio is being recorded by the camera. A strong password will use at least 8 characters, upper and lower case letters and will include numbers / special signs. Another flaw to consider is that many wireless cameras transmit their signal at a 2.4GHz frequency. This can lead to signal interference with other devices in your home (Bluetooth devices, cordless phones, microwave ovens etc.) and will lead to your cameras being unable to record and/or transmit any data. There are even devices that are created just for detecting and tuning into these frequencies (http://www.covisec.com/find-cameras-in-your-vicinity-compact-professional-camera-hunter-with-display-lmcdpromini/) to display what exactly can be seen through the camera. Luckily, there is technology that will enable you to switch to a safer and less used frequency to reduce any kind of interference that you might be experiencing. The HS580Deluxe wireless receiver ensures no lost video due to external wireless devices, such as WiFi and cellular. The transmitter uses the 5800MHz (5.8GHz) channels to help eliminate interference from other wireless devices in your home or business (HS580 Deluxe Wireless Receiver Info).
The most secure way to use wireless cameras would be to simply not expose them to an outside network. This will limit your ability to create an external connection for mobile viewing but it will reduce the chance of an outside attack. Firewalls or other intrusion prevention systems, will work to secure your connection and enables you to limit connections to authorized IP addresses. Other security measures like throttling your bandwidth rates and enabling flood guards, will secure you from outside brute-force attacks (5 ways how to secure your wireless connection). The most important thing to keep in mind is still that you want to use cameras that work with an encrypted signal. The SVAT's GIGAXTREME 301 (http://www.covisec.com/gx301-013-2-digital-wireless-cameras-with-receiver/) would be a great example of a more secure wireless camera option. This system can be used to monitor and record video and audio in any indoor or outdoor space at any time of the day. The weather resistant cameras included with this system have 18 infrared LEDs that allow you to see up to 40ft away in the dark. Its advanced system, automatically connects on its own so you will be watching clear, interference-free footage in a matter of seconds. Superior digital functionality ensures that the signals passing between the camera and receiver remain strong as you monitor your business or home wirelessly, up to 450ft away. This wireless system is ideal for monitoring entrances, backyards, valuables, employees, or any other situation that you need.
Although wireless camera systems may seem intriguing (considering the ease of installation), there are many different features to keep in mind when securing your home / business. Many wireless cameras also include features such as long battery life, a large memory for storing all your videos and motion detection. Encryption type, frequencies and other security options should be considered before purchasing a complete system.If you have more questions about setting up your home / business with a wireless or wired system, feel free to contact us for a consultation.
