Wireless cameras are simple to set up and use.
If you are thinking about adding a wireless camera to your existing security system, or just want to find out more about wireless security cameras, this article is for you. You'll find out about the various models and versions of wireless security cameras available, from the earliest ones, to IP cameras you can easily connect to an existing wireless network.
A wireless security camera can be used in closed-circuit television systems (CCTV) for surveillance and monitoring. They transmit a video and (sometimes) audio signal to a remote monitoring station using radio frequencies. Power for the camera is obtained by either plugging in to a convenient power jack, although some models are powered by batteries ,or by solar panels.
Early Wireless Security Cameras
First Generation wireless cameras transmit their signal using radio frequencies of 900MHz and 2.4GHz and 5.8 GHz. Note that most of them operate over the 2.4 GHz band, the same band that a lot of household wireless appliances, such as cordless phones and video game controllers, operate on. Interference may result when using in the home.
The advantages of analog wireless security systems is they are lower cost than their digital brethren, and you can use multiple receivers.
The disadvantages are they may cause interference with other devices in the home. The transmission is not secure. the video signal quality is lower than digital, and any interference makes it worse.
900 MHz systems can be used in installations where the signal must go through drywall or even trees to reach the receiver. There is also not a lot of interference with other devices. Unfortunately there are only two channels available at 900 MHz.
For more channels, up to 12, look at 2.4 GHz wireless cameras. Since there are many devices now that use this frequency range, you may have interference.
5.8 GHz setups have a better chance of success, since there is less interference and there are 8 channels available (so you can have up to 8 cameras). The biggest challenge is the signal cannot go through many walls without lots of degradation.The newest analog systems use the 5.8 GHz frequency band. You get up to 8 channels (for 8 cameras), the downside is that the signal is easily obstructed by walls, trees, etc.
Transmission Power
Lower cost 5.8 GHz systems most likely have a 10 milliwatt transmitter, which ideally can transmit to 300 feet with line of sight between the transmitter antenna and the receiver antenna. This rarely happens. This is a broad generalization and conditions such as distance, weather and clear line of sight affect this greatly.
When selecting an analog wireless security camera system, make sure you find out the transmission power and determine whether this will be enough to overcome any obstacles in your system.
Newer Digital-based Wireless Security cameras
Digital security cameras use high bandwidth radio frequencies.
Some of the advantages of this type of system are:
The range of transmission of the signal is as much as 450 feet with line of sight between camera and receiving station
The quality of the signal is very good
With a digital system you can easily have two-way transmission - allowing an operator to communicate with the remote location
High security of the signal.
Networked Wireless Security Camera
Wireless security cameras are now available that can connect through a local area network over commonly available wireless systems. These are often referred to as "IP security cameras." Essentially, these cameras become a "web page" with their own unique IP address. These include 2-way audio feeds, encryption, pan, tilt control and automatic night vision. These newer wireless security cameras have replaced the earlier digital wireless cameras, due to the popularity and ease of installation of Wi-Fi networks.
Buying And Installation Tips For An Outdoor Wireless Camera
There’s an outdoor wireless camera for almost every budget and purpose you can think of. But before you get excited and start splurging on equipment you don’t need, take note of the following tips regarding how to choose and set up an outdoor wireless camera.
1. Consider if you really need it. The common mistake of many homeowners and proprietors is they use high-tech solutions to solve low-tech problems, which ends up wasting money. If your problem is vandalism of a dark perimeter wall, simply installing lights is the wiser and cheaper option to setting up an outdoor wireless camera.
2. Check for line of vision. Most entryway plans are probably simple enough to make do with a single outdoor wireless camera. But some are more complex and may require two cameras or more. Alternatively, mounting an outdoor wireless camera on a special base may save you the extra purchase.
Hint: Line of vision also affects wireless video signal quality.
3. Check for distance. An affordable outdoor wireless camera can usually capture images up to 20 feet. You may want to go for an even more affordable unit if your yard or store entryway isn’t that big.
4. Check visibility. Your outdoor wireless camera should be capable of capturing night scenes. If you find that night vision capabilities put the purchase outside your budget and the surveillance area isn’t large, then simply light the area. But if you intend the camera to capture a wide area, make sure that lighting it won’t make your monthly energy bill cost more than the price of a night-capable outdoor wireless camera!
Hint: Switching to black & white mode in low-light situations can increase visibility.
5. Prepare to record. Whether you have a night watchman or not, you should be able to record images on your equipment. Beware of buying a cheap camera that requires you to buy additional stuff just to record surveillance video. Your outdoor wireless camera should be able to send wireless video signals that can be readily recorded on your PC or VCR.
6. Don’t record audio outside your property. Did you know that it’s illegal in the US to record the voices of people in public places? So if you intend to purchase an outdoor wireless camera with voice capturing/recording capabilities, make sure to use it only inside your home, store, or office.
7. Don’t use a dummy. Another thing that can make you legally liable is setting up a dummy camera, even as a supplement to a genuine outdoor wireless camera. Creating security expectations where none exist can give you legal problems in the future.
