You know the myriad of activities that go on in a large metropolis. People go to offices to take care of business, shop owners try to sell their wares, students go to attend classes, and drivers maneuver the cars and trucks around—such a lively bunch of activities.
Unfortunately, a less-than-pleasant activity also strives in the city—crime. Every city has its share of lawbreakers that disrupt its peace and harmony. Crime can range from simple violations, such as illegal parking and speeding, to really serious ones, such as, murder. To combat them, each city dispatches law enforcers. Law enforcement uses the latest in weaponry, technology, and techniques in catching and apprehending criminals.
However, in most cities, the officers of the law are usually outnumbered. To make up for the disadvantage, they resort to surveillance cameras to monitor public areas. Surveillance cameras alert operators to areas where violations of the law occur, allowing them to dispatch police officers more quickly. Also the images caught on tape can be used as evidence if the criminal does manage to get away.
New types of surveillance camera are in use now in many cities. These are called wireless security cameras. As the name implies, these cameras are not connected by any wires. Standard cameras are connected to a central monitoring system via cables.
These wireless gadgets are gaining popularity. In fact, police units are installing them on several areas in the city. Too, government agencies, businesses, and private citizens are also using them.
The main advantage of a wireless system is that these systems are not limited by cables. That means they can be placed anywhere without much concern about the placement of cables. The signal is carried via a broadcast signal, which can also be accessed through the Internet if permission is approved.
Wireless systems generally use a five-to-one compression ratio. Higher compression rates are also available so that the images would be DVD quality. The downside of this high compression rate is that the hard-disk space of wireless cameras are filled faster than with a cable-fed camera. Wireless systems can time stamp the images.
Furthermore, more advanced wireless security cameras can alert operators by sending them an e-mail if an unusual activity is detected.
There are also disadvantages to the usage of wireless security cameras. For example, digital video recorders can sometimes pick up the signals from these cameras, threatening the security of the images. Also, if one knows the proper frequency, the signals can be jammed. Jamming a transmission means scrambling or blocking the signal so that it does not register properly in the monitors. Jamming a police transmission is a crime and is dealt with severely.
Also, they are not appropriate for long-term surveillance. That’s because transmitting the signal requires a larger-than-usual amount of power, draining the battery power more quickly than their wired counterparts. Also, if they are not stored properly, they can be stolen with ease; there aren’t any wires that are attached to them which helps secure these gadgets to their mounts or posts.
Wireless Security Cameras – One of the most Popular Devices Used for Office Security System
One of the biggest hurdles of camera security system is that it is not possible to relocate them as and when it is required. Even if you relocate those lots of time will be wasted and so in the meanwhile your objective will not be achieved.

Wireless security camera can help you to detect crimes and thefts at a swift speed and also help you to minimize the damages.
Components of a Wireless Security Camera
A wireless security camera system consists of three main components namely camera transmitter and receiver. A camera is used to record and reproduce pictures and images in video form along with sound and other facilities. On the other hand a transmitter is used to transmit the recorded video to be viewed in a television or computer. A receiver is a device on which the wireless security camera is mounted. Even though the wireless security camera can easily be moved among places they should always be kept in the receiver for safety purposes.
How is Wireless Camera different from a Hardwired Camera?
Wireless security camera system is much advanced when compared with a hardwired camera. While using a hard wired camera you not only consume lot of time in moving it to different places but will also have difficulty in tracking the crimes or preventing the damages. Apart from technological advancement you will also find it lot more convenient to operate a wireless camera when compared with hardwired camera.
How does Wireless Security Camera Work?
Before shooting you must connect the receiver of the wireless security camera systems to some device like TV or computer as said earlier. This will help in displaying the generated output. You can keep the camera in any place and if you want that to escape the attention or vision of the subject you must make some sort of secret arrangement to ensure the same.
All About Wireless Security Cameras
A wireless security camera can be used in various applications where a wired camera is not practical for surveillance and monitoring. They work by transmitting a video and (sometimes) audio signal to a remote monitoring station using radio frequencies. Power for the camera is provided by either plugging in to a convenient power jack, although some models are powered by batteries ,or by solar panels.
Early Wireless Security Cameras
These analog cameras send an “analog” video signal to a receiver, which is then connected to either a television monitor or a recording device, such as a video tape recorder, or digital video recording system (DVR). A majority of these cameras and systems use the 2.4 GHz frequency, which is the same band used by many other wireless devices, like cordless phones and even computer networks. It’s possible that these various systems can interfere with each other when in use.
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.
2.4 GHz systems are more common, and there are 12 channels available, however, it is rare that you can find a channel that is not already in use by another wireless device.
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.
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.
Digital Wireless Security cameras
A digital security camera converts the video information to a digital signal, which is then sent to a compatible receiver.
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 stationThe quality of the signal is very goodTwo-way communication between camera and operator if requiredIt is difficult for others to capture the radio signal and interprets it, using modern digital security methods
Wireless IP Security Camera
Wireless security cameras are now available that can connect through a local area network over commonly available wireless systems. 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. Because of the popularity of wireless networks, you will find more and more of these cameras being used in security camera systems

Wireless Security Camera System
Security cameras have become commonplace for surveillance in banks, airports, convenience stores, etc. Closed circuit video cameras transmit the recorded data to digital video recorders and remote monitors so that the footage can be recorded. These days many residential homeowners who invest in some type of security system prefer to have a wireless security camera system because of the ease of installation.
You can choose between four common types of wireless cameras: infrared cameras, bullet cameras, board cameras or hidden cameras. Infrared cameras can be used outdoors by simply connecting the transmitter to the camera. Bullet cameras and board cameras work the same way but can only be used indoors. Wireless hidden cameras have built in transmitters and come in the form of clocks or air purifiers, etc, depending on the brand. Other types include the dome camera, and covert camera, PTZ (Pan, Tilt and Zoom) camera. Other wireless cameras include night vision, and can automatically switch to night mode once light fades.
Here’s a quick run-through of how a wireless security camera system works. Cameras have wireless receivers that transmit signals to in-home receivers. Depending on the model and/or brand of wireless camera, the in-home receiver can be connected to your own television. Signals can also be transmitted directly to your mobile phone, laptop computer or other mobile devices. Old models used to transmit signals at 900 megahertz. Before recent technology, signals were easy to intercept at such a low frequency. Burglars could easily hack into the security system and have a quick look inside your home before breaking in. Now, average signal frequency are up to 2.4 gigahertz and more difficult to intercept.
