If you have property to keep safe and wish you could keep an eye on it all the time, then an investment in wireless camera security systems could be the answer to your home security needs. While a significant amount of money, there’s no wireless security system with a greater cost than the property and possessions you’d want to protect with it. In hard economic times, even ordinary people get desperate and turn to things they never thought they’d do… like burglary. Do you want to gamble on no one ever breaking in to your home or office? Sure, you have a lock, but has an ordinary lock ever stopped a determined criminal intruder? Even just the visible presence of a video surveillance camera will often intimidate many criminals before the crime is even done. Wouldn’t you rather keep people from accomplishing a crime in the first place, instead of tracking them down after the fact? It’s better for them AND you! And if the worst happens and the burglary continues, the police will have a solid recording to go on. Without that, finding a criminal can be almost impossible in some cases, but with recorded footage of the dead it becomes much more likely that justice will be served, and that you’ll get your belongings back and have damages compensated for.
Wireless security camera systems make heavy use of closed-circuit signals. This adds an extra layer of protection to the signals by sending them only to a specific set of monitors, rather than broadcasting them over a general area. Only you should be able to see your video feed, and that’s only the least of the common features used in these cameras today. While early cameras used for security purposes were clunky and primitive, today the market provides access to security cameras with zooming, color, and even lens wipers for rainy weather. This technology is so vital and useful to defending property and preventing crime that there isn’t a government in the world that eschews it, and they’re almost mandatory as an added security measure for places such as hospitals and airports. You can even buy a wireless security camera system with the ability to talk to the people under surveillance!
A wireless camera security system can come in several package variations. Some may include a monitor specifically designed to be used for the system, while others will hook up to a monitor you already have in place. If you wish to skimp on a few features, you can get a decent security camera in and of itself for the price of a birthday cake. However, if you want an expansive system with great durability and reliability that really covers all the angles a criminal could exploit, you’ll need to look at the packages available in the one and two hundred dollar range. However, the near-universal standard for wireless ability allows you to install a system, whether it’s cheap or expensive, with little trouble and next to no experience as an electrician or do it yourself handyman. The benefits to owning one of these systems are many, and the expense for a basic functional product really isn’t that great… so why would you consider going without one?
Wireless Security Camera System -- Which Frequency Should I Use?
More and more people are interested in setting up wireless security for their homes. There are a lot of reasons why this is so. Some install wireless security cameras because it's now so easy to set up. Others just love the fact that you do not have to drill holes all over the place since it's now a wireless approach. Whatever the reason may be, wireless security cameras are quickly becoming the preferred method of surveillance for many people.
Wireless security cameras are so popular because users can literally put them almost everywhere they feel that protection is needed -- and the homeowner doesn't have to worry about wires. Because it's wireless, you have tremendous flexibility in terms of placement, you just need to know what you are doing. Remember that wireless systems tend to fail if you do not follow basic precautions during the install.
What can possibly go wrong? For example, you might have installed the camera but as soon as you turn it on, you cannot get the signal on the receiver. Fortunately, this type of problem can be easily solved. If you are thinking of doing the install on your own or with help from a friend, there are three frequencies that are on the market for the general public.
Frequencies that are Available: 900MHz, 2.4GHz and 5.8GHz
Remember that the lower the frequency, the more walls your system can get through
* 900MHz wireless security cameras can be used in installs where the signal has to go through trees or dry wall in order to reach the wireless receiver. This bandwidth doesn't have that much interference from other devices, and as a result, the signal can be relatively strong. The drawback is that right now there are only two channels available on this frequency, making its use very limited.
* 2.4GHz wireless security cameras are the most common on the market. So are 2.4GHz phones, wireless routers, keyboards, and mice that we all use. Basically, if you see something wireless on the market, there is a good chance it is on a 2.4GHz frequency. As a result, a lot of the wireless 2.4GHz security cameras stop working. There are up to 12 channels available on 2.4GHz frequency that you can select for transmission, but unfortunately, it's hard to find one channel that is not already being used, especially if you live in a big city.
This is where the 5.8GHz transmitters and receivers come in. The 5.8GHz frequency is relatively clean, and subsequently, the successful wireless camera installation rate is higher. You can have up to eight analog wireless security cameras on 5.8GHz frequency. But the 5.8GHz frequency has an issue. It does not go through walls as effectively as the 900MHz or 2.4GHz frequency. This is a huge disadvantage.
So what do you do? A 900MHz setup can only connect two cameras, the 2.4GHz is slightly better but conflicts a lot with other common devices, and the 5.8GHz can support more but cannot go though obstacles efficiently. To resolve this issue, some security camera manufacturers have started placing high power 5.8GHz transmitters and better quality antennas in their wireless cameras. As a result of this addition, 5.8GHz wireless security cameras can now send a camera signal through a wall.
If you find a 5.8GHz camera and receiver on the market for under $200, chances are it has a 10 milliwatt transmitter in it, which is the lowest power transmitter on the market. In ideal conditions with line of sight, you can stretch it to 300 feet (in theory). In reality though, that is never the case. This is due to signal interference as it goes though walls. If you are looking for a camera that can transmit video up to 500 feet away, you need a camera with at least a 100mw transmitter. If your objective is over 1,000 feet, look for a system with a one watt transmitter.
These are very general numbers and can change based on the distance, weather, and availability of a clear line of sight. A good way to increase the odds of success is to put the security camera and receiver antenna as high as possible so that they have a clear line of sight. Before making any purchases however, make certain that you identify your own specific needs for a security system so that you receive the proper protection for your home or business. And if you still are not comfortable choosing the right system for your needs, just consult a professional!
