In recent years, the use of wireless security cameras is becoming more and more popular.There are many reasons for the surge in interest.Some people use wireless security cameras for ease of installation.
Others use them because the wires are not possible or cost-effective.For whatever reason, wireless security cameras are quickly becoming the preferred way for many to monitor.Wireless security cameras are very popular as users can put them wherever they need extra protection ---Users don\'t have to worry about the wires.
As long as the installer does his or her homework, the placement of the security system is very flexible and easy to install.If precautions are not taken, the failure rate of the wireless security camera at the time of initial installation is very high.What kind of failure?Let\'s say you installed the camera and powered it, but there is no signal reception on the receiver side.
Fortunately, the problem can be solved through some due diligence.When you consider installing a wireless security camera (whether you install it yourself or with some help), there are three frequencies on the market for public use.Select security system: 900 MHz, 2.4GHz and 5.The lower the frequency number, the more walls/objects your safety system can pass through (except for concrete and metal ).
--The 900 MHz wireless security camera can be used for the installation of the wireless receiver where the signal must go through the trees or drywall.This bandwidth is not subject to much interference from other devices, so the signal may be relatively strong.The downside is that there are only two channels available at this frequency now, making its use very limited.
--2.
The most common on the market is the 4 GHz wireless security camera.So are 2.4 GHz phone, wireless router, keyboard and mouse we all use.Basically, if you see something Wireless in the market, there\'s a good chance it\'s on number 2.
4GHz frequency.
As a result, a lot of wireless 2.
4 GHz security camera failed.
There are up to 12 channels on 2.
You can choose the 4 GHz frequency for transmission, but the reality is that if you live in a city like New York or Los Angeles, you can\'t find a single channel that is not occupied by wireless devices.To solve this problem, some manufacturers have already started using 5.8 GHz transmitter and receiver in wireless security camera.
The 5.
The 8 ghz frequency is relatively clean, and then the successful installation rate of the wireless camera is higher.Up to 8 analog wireless security cameras are available.8GHz frequency.But the 5.There is a problem with the 8 ghz frequency.
It will not pass through the wall as effectively as 900 MHz or 2.4GHz frequency.This is a huge disadvantage.So now, we have 900 MHz where you can only have two cameras (not very practical) and two.4 GHz, it has almost all the devices known to humans, 5 GHz.
8 GHz, relatively clean, but it fails when you try to send a signal through the wall.To solve this problem, some security camera manufacturers have started to place high power 5.Their wireless camera is equipped with an 8 GHz transmitter and a higher quality antenna.
5 due to this increase.
The 8 GHz wireless security camera can now send a camera signal through the wall.If you find a 58 GHz cameras and receivers on the market for less than $200, most likely one of them has a 10 milliwatt transmitter, the lowest power transmitter on the market.In the ideal case of sight, you can stretch it to 300 feet (theoretically ).
However, this is not the case in reality.
The interference and the Wall reduce the signal strength.If you are looking for a camera that can transfer up to 500 feet m of video, you need a camera with a minimum of 100 MW transmitter.If the distance is greater than this, say 1,000 feet to 2,000 feet, you need a system with a tile transmitter.
These are very general numbers that can be changed depending on distance, weather, and availability of clear sight.A good way to increase the odds of success is to place the security cameras and receiver antennas as high as possible so that they have a clear line of sight.However, before making any purchases, please make sure you identify your specific needs for the security system in order to get the proper protection for your home or business.
If you still need a little help choosing the right system, don\'t be afraid to ask professionals!
