Even though wireless security cameras are typically easy to install, they are available in several different choices for connectivity – which can make a huge difference in installation, image quality and overall performance. The classic wireless camera system broadcasts the radio signal over the air to a receiver, which is tuned to the same frequency as the cameras, just like in old analogue broadcast TV. The main downside of this type of signal transmission is that it’s prone to interference problems, which often cause the video to become distorted or break up completely. The signal can also be intercepted by anyone with a baby monitor or wireless scanner, making it vulnerable to prying eyes. In addition, it can be quite difficult to install multiple wireless cameras within this system as they usually experience cross-talk with each other.
While “analogue wireless” cameras are still being utilized in surveillance systems found in many households and businesses today, more advanced, digitally-paired wireless systems that address the above-mentioned issues have been developed. These systems modulate the video signal into a digital bit stream, which is then transmitted as data between the cameras and the receiver, the same way modern digital broadcast TV works. This produces a secured connection between the wireless cameras and the base station, making it virtually impossible to eavesdrop. The buffered, digital signal also prevents signal loss, which causes distortion or noise, and greatly improves image quality. Wireless IP cameras are the latest development in CCTV surveillance. In an IP-based wireless system, each camera outputs a data stream, rather than a video signal. The cameras use Wifi to connect to the wireless network and software to manage the cameras. Wireless IP cameras provide the highest quality video performance.
Wireless camera systems are typically uncomplicated, so you can install the equipment on your own. While the camera installation process may vary slightly according to the model, the basic installation procedure for wireless cameras is the same.
- Decide which part of the house to install your wireless video camera in. Most wireless security cameras can be installed indoors or outdoors. But outdoor wireless cameras are specifically designed with a wider viewing angle to help monitor large outdoor areas. They also come with night vision and a tough, weather-resistant protective housing.
Mount your cameras near entryways so you can record anyone entering the house or exiting. It’s also recommended that you install cameras directly above your valuables so you can monitor them at all times. Other ideal locations include: around the perimeter of your property and areas where they can be seen by anyone inside the property to deter potential intruders. Make sure there’s no obstruction between the camera and the receiver if you’re installing an analogue wireless system.
- Identify the most appropriate angle for the cameras. Ensure the camera allows you to keep watch over the largest area possible.
- Bolt the camera mounting plane onto the wall. This will typically require you to get a power drill, bolts, screw, and mounting brackets. Most surveillance cameras come with the required hardware. Check the manual for specific manufacturer instructions regarding the installation of your particular model.
Hold the camera’s mounting bracket into place using one hand, and then use the other to mark the screw holes with a pencil. If the screws need to be in a stud, get a stud finder from a local store so you can find an appropriate place for mounting. But if the camera doesn’t have to be screwed into a stud, you can hold the camera’s mounting bracket into place using a drywall anchor bolt.
- Place the wireless video camera on the mounting plane.
- Plug the video camera into the power outlet or insert the batteries.
- Follow manufacturer instructions to synchronize the video camera to your receiver.
