Security cameras are a great way to augment a home security system, but the sometimes can be difficult to install. Wireless security camera systems have the 4G Solar Camera convenience of not having to be hardwired into a system. They do need power, but they can be plugged into a standard outlet, or battery powered for remove convenience. You can also use a wireless security camera system to record the video feed, or with certain types view the video live over the internet from anywhere in the world. Let's take a look at the three main types of wireless security camera to see what's right for you.Outdoor Wireless Security Camera SystemUsed in a typical home security setting, the outdoor wireless cameras replace the standard hardwired camera. They will need some sort of electrical power, but that can be provided by a standard electrical outlet. There are ones that are battery powered but to remain on all day can drain the battery quickly. You can find solar powered cameras but they could lose power in the event of consecutive rainy days or overcast weather. Still if you don't want to go through the trouble of hardwiring your cameras they might be a good option for you.Wireless IP Security Camera System.A relatively new addition to security cameras is the IP security camera. These cameras function in a similar way to a webcam, except they don't need to be hooked up to a computer. The camera signal is sent back to a base or connects to your home wireless internet. Basically the camera is a self contained webcam. The benefit is that you can log into the camera any time or any place you have a internet connection and see what the camera sees. This real time monitoring can be recorded via computer or digital video recorder. Nanny CamA nanny cam is a wireless surveillance camera system disguised as an everyday household object. You can get clocks, DVD players, children's toys etc, that have hidden cameras built into them. They can function just like the real object but have the added surveillance system. Many people use these to view caretakers (like nanny's) or employees in their homes. These digital wireless security camera systems can be recorded to DVR or be combined with a wireless IP camera so that you can view the live video remotely via the internet at work.Wireless Surveillance Camera SystemsA cheap wireless security camera system, isn't really an option. The camera must have the video transmitting hardware built in, adding to the expense. The lower end systems can be about the price of a high end hardwired camera, but their real benefit is the convenience and ability to place them where it would be hard to install a wired camera.
