If you are trying to buy a brand new surveillance system or looking to upgrade your preexisting security system, wireless security cameras might be a very tempting option. What is so special about these kinds of CCTV cameras you may ask? They transmit video and audio to a wireless receiver. They are usually powered by at least one cable or wire. So, wireless does not refer to this aspect. Rather, it refers to the fact that the video or audio can be transmitted without using any wiring. At this point, you may be wondering if they are practical or not. Their installation costs are low and the mounting options they provide are very flexible. On top of that, they have all the features a standard security camera might provide including but not limited to motion detection infrared night vision and audio monitoring. What you need to bear in mind is that every wireless camera needs to have a specific receiver. Why are the requirements so specific? Because this kind of pairing creates a connection that is steady and reliable and it diminishes signal interference.
Difference between wire-free and wireless security cameras
Even though the names might sound familiar, it is important to bear in mind that there is a very big difference between wire-free security cameras and wireless cameras. What is the big difference? The biggest difference that one might notice is that in order to have 24/7 coverage and a night vision that works at longer distances, the camera has to be plugged in. Wire-free cameras on the other hand work very differently. How do they work? They work by only recording footage when they detect motion. These cameras do not have to be connected to the DVR for storage and because of that, cables are not necessary whatsoever. What benefit does that provide you may be wondering. Because there is no need for cables, the cameras can be placed essentially anywhere.
Features of Wireless Cameras
You may have already figured out the best benefit that comes out of using wireless cameras. It is the fact that you can run these cameras without having proper wiring and because you do not require a good cable. As a result, you can save a lot of time and money. It also makes the installation process a lot easier as well. The fact that you can place a battery-powered camera anywhere without having to go through the hurdle of drilling, wiring, or even looking for an electrician can be very alluring. One other benefit that may not be so obvious is the fact that wireless cameras do not have the risk that wired cameras often run in the sense that skilled trespassers can tamper with the cable. So, in a way, this is way more secure. On top of that, if there is an electricity outage, the cameras will continue to work because they run on a battery pack.
Skilled intruders won’t be able to disrupt a wireless camera by tampering with the cable because there is no cable. Also, wireless cameras can typically transmit videos up to a receiver 500 feet away with a clear line of sight. In addition, this increases the risk of signal interference issues. In a power outage, your camera will continue to work because it is run by a battery pack. You also will be able to back up your footage since it is backed up onto the cloud and not an NVR or DVR.
Analog and Digital
There are two kinds of cameras, digital and analog. Analog sends the signal over coaxial cable to a DVR. The DVR converts the video from analog to digital signals. Digital records the images digitally and sends them over a computer network instead of going through a DVR first. Analog uses a separate transmitter to connect to a digital video recorder (DVR). Digital wireless cameras, or WiFi cameras, can connect to the internet. Analog wireless is the transmissions of video and audio signals using radio frequencies. In addition, they typically operate on 2.4GHz frequency. Also, most household routers, video game controllers, cordless phones, and microwaves operate at 2.4GHz and may interfere with your camera. Analog wireless cameras are cost-effective.
