The Different applications for wireless video cameras

Wireless spy cameras have loads of uses several of the key purposes include catching mistreating care givers, cheating spouses, nosey landlords, stealing roommates and detecting employee thieving.
1) Wireless spy cameras can be black and white or color.
You will get better object definition from a colour wireless spy camera but are often a little bit more pricey. The price of black and white units have the tendency to be a little cheaper and image resolution can be somewhat higher
2) Low Light capability
Light sensitivity is measured in LUX. The lower the LUX level the lower light the camera can work in. Spy Cameras with a LUX rating of 0.1LUX or less will be really reasonable in low light conditions. If you require pitch dark covert performance go for a spy camera unit with a rating of less than 0.03LUX.
3) Image Picture quality.
Measure. The more Television Lines your camera produces, the greater the quality of image will be. Even for the most discerning of private researchers 380 TV-Lines will be okay.
4) Does the receiver come as part of the package?
The receiver is connected to your viewing / recording device: TV, VCR, PC or Digital Video Recorder (DVR), so you can capture and or view the incoming video and audio signal from the wireless camera. If the receiver is not included as part of the kit, inquire how much one would cost and see if it is in your budget.
5) The radio frequency the camera Transmits on.
This is the wireless spy cameras transmission frequency range used to send the video / audio signal to the receiver. There are presently 434MHz, 900MHz, 1.2GHz, 2.4GHz and 5.8GHz transmission frequencies ranges. Probably the most popular frequency exists in the 2.4GHz range, this range is license free in America and all across Europe up to a yeild of 10mW.
It's possible you could get wireless interference on any of the wireless ranges but because of the number of products that utilize them, 434MHz and 900MHz can be particularly problematic.
6) The signal transmission distance
Transmission range is generally quoted as 'line of sight', it is the maximum distance between the wireless spy camera and receiver without obstacles or interference . This distance can be anything from 150ft to 1000ft and is dependant on the model.
7) Hidden Camera or Stand Alone
There are minute wireless spy cameras expressly created to be obscured by the operator, however, it's also possible to find pre-concealed units that will come created into an everyday object. Smoke detectors, ties, eye glasses, cigarette packets, lamps, teddy bears, air fresheners, mirrors etc. So depending on your application, you may want to get a pre-hidden wireless spy camera and you are all set. You still use a receiver like the stand alone spy cameras but pre-concealed cameras are more convenient and easier to place and install in your home or business.
Warning: If you intend to work with wireless cctv camera you will most probably have to get around obstructions and interference, so never accept the transmission range advertised as in the real world the working range will not go as far. Before purchasing always ask for more realistic transmission ranges.
So now you have the necessary knowledge to buy a first-class wireless spy camera, remember to keep in mind these 7 basic elements for choosing one. It could make the difference between getting the evidence you wish or not!

Types of Cctv Cameras

CCTV cameras are being installed everywhere for crime prevention and detection. They are now available at quite affordable price, are easy to install, and require low-maintenance. There are many types of technologically advanced CCTV cameras that offer fitting surveillance solutions. Depending upon your requirement, you can select one. This article discusses types of CCTV cameras and their features and uses.

Indoor Camera: Indoor camera as the name suggests are used for indoor security mechanism. Depending upon your security needs, you can mount it at any suitable location inside the building. These are suitable for security in homes, schools, offices, hotels, etc.

Outdoor Camera: Outdoor CCTV Camera is used for outdoor places. They are mostly used for entry and exit points with limited night lighting. Outdoor cameras typically have hard shell vandal-proof casings and a variety of lens options.

IR Day/Night Camera: IR Day/ Night Camera are used for high alert security areas where surveillance needs to happen throughout day and night. In the daytime the camera functions like a normal camera with standard colors and at night it switches to low-lux black and white mode. When visibility decreases due to no-light at night, Infrared LEDs are automatically illuminated providing full security. These cameras are used by military personals, in parking lots, and high security zones.

Dome Camera: Dome cameras are installed inside a dark dome and are designed in a way that they go unnoticed by visitors. They come in compact design for a discreet appearance. The thief does not know if the camera is recording. These cameras can also be rotated and tilted manually. Dome type cameras are used in public places like railway station, bus terminals, and other areas where there is huge gathering of people.

Bullet Camera: Bullet cameras are placed inside a bullet shaped housing, and they are used in residential places as well as commercial places. They are small in size, have an integrated design, and are really effective. They offer illuminate viewing even in darkness and are weatherproof as well.

Vandal Proof Camera: Vandal proof cameras are used as outdoor security cameras. These cameras are sheltered within solid material and are covered by a “hub” of break-proof glass which doesn’t hinder the quality of the video camera streams. It is difficult to break these cameras and this makes them perfect for high security. They are suitable for wall or ceiling mounting and are rain and fog resistant.

Hidden Camera: Hidden cameras are compact in size and are used for secret monitoring. They are usually installed in public places like department stores, theatres, clubs, etc. Hidden cameras have a built-in recorder that records and broadcasts simultaneously. By using a large number of security cameras and networking them various strategic views of the place can be obtained.

Pan Tilt Zoom Camera: Pan-tilt-zoom camera offers the ability to view and zoom in all directions. You can even set the camera to automatically rotate to different fields of vision. To gather more information on CCTV cameras, cables, monitors, and connectors, visit www.closeoutcctv.com.

A Brief Introduction to IP CCTV

Network cameras have been around for a little over five years now. Initially network cameras found a niche as a form of web camera. They became very popular for monitoring landmark sights and tourist attractions. Their ability to connect to a network and use ftp technology to transfer images to websites made them ideal for such applications.

As time passed recording software was developed by a number of manufacturers which enabled these network cameras to be attached to a local area network and to have their video recorded by a PC at some other point on that network.

In order to minimise the hard disc capacity required for continuous recording sophisticated Video Motion Detection algorithms were developed. By this method these cameras were continuously monitored but only actually recorded to disc when activity was detected.

The early cameras had some limitations when compared with traditional analogue CCTV cameras; low-light performance was not as good, frame rates were often slower than the 25 fps standard from CCTV cameras, they were not all suitable for outdoor duties, and those cameras which could truly compete with CCTV cameras were comparatively expensive.

Despite these limitations of the early camera devices network cameras were still well suited to certain applications. Early adopters included educational establishments. Schools, colleges and universities tended to already have in place extensive Local Area Networks (LANs), existing rack rooms where they could simply add extra discs for video recording, and the majority of their areas of interest were indoors and well-lit e.g. school corridors, IT classrooms, refectories, sixth form common rooms, and the front desk reception area.

Where the cameras suited the application, and there was already a network in place, these cameras proved to be an extremely cost-effective surveillance solution.

After several years of progressive development the current crop of network cameras delivers image performance above that of traditional CCTV cameras. Megapixel cameras have become common place from many manufacturers; some have even produced 2, 3, 5, 11, 16, and even 21 megapixel cameras! These cameras are capable of fulfilling the duties of several traditional cameras, due to the sheer amount of pixel resolution within the images produced.

It is now possible to zoom-in, after the event, within recorded video, and actually see enlarged clear detail. This capability makes them an ideal option for facial recognition, reading number plates within a scene, and other high-definition requirements.

2.75 million security cameras installed in China

China is planning to boost their use of Security Cameras.
On Monday an article came out about security cameras in China. China’s police say they have installed 2.75 million surveillance cameras since 2003 and plan to expand the system into the countryside, which is home to about 800 million of the country’s 1.3 billion people.
The cameras are the most visible components of police surveillance, mainly in urban areas, according to a news release posted Monday on the Chinese Public Security Ministry’s Web site.
These camera security systems have proved controversial in other countries, like Britain, which reportedly has 4.2 million surveillance cameras installed – which is about one per 14 people. The ratio of cameras to people stands at only one to 472,000. The camera-to-person ratio is believed to be much higher in China’s cities, with the capital Beijing having 265,000 cameras.
No dialog or privacy rights has arisen in China, where tight communist political control and broad and intrusive police powers have been the norm for half a century. However, China’s plans to combine surveillance cameras with face recognition software has raised concerns about how the equipment will be used.
The Associated Press reported “Thefts, burglaries and purse snatching have all more than doubled since the 1990s amid rising wealth inequalities and relaxed social controls, with about 4.75 million cases reported in 2007, the last year for which statistics were available. However, police say violent crime has declined in recent years with better enforcement of rules governing weapons and explosives.” The Chinese police believe that the expansion of camera security to the countryside should “put the safety of the broad masses of the people first and foremost.”

CCTV Camera Tip: Apply Simple Common Sense when Picking CCTV Cameras and Lenses

Get a good face shot: Use Higher quality cameras at entry areas.
Doors, gates and other entry areas need a good quality, high resolution camera to record a good 'face shot.' The video from this camera should be considered a highly valuable since it can be used as evidence in identifying a person in a court of law.
Wide Angle Cameras for large surveillance areas
Once you can get a good shot of a persons face, you should use a wider angle camera lens for the interior surveillance spaces of the building. Using color cameras inside your building is a good idea because you can readily identify a person by the clothes they are wearing. Used in conjunction with the face shot at the entry point, you have an excellent record of all people and activities in your surveillance areas.
Consider the following when choosing a CCTV camera:
1. Sketch out a Floor Plan: Put in all camera locations. Consider the distance to your surveillance zone: Are you 5 feet or 15 feet away from your surveillance target area? It is best to locate your camera as close to the surveillance area first, then choose how much zoom you need. Do you need 4mm, 8mm or 12mm lens?
2. Field of view or area of surveillance: Take photos of areas you want to cover from the proposed camera locations. What lens you need depends what you want to see and how far away and how wide a viewing area. Wide angle and fisheye lenses are available.
3. Resolution: Do you want to capture a persons face or a car license plate? Each camera location will determine which lenses would maximize your surveillance potential. Do you need 50mm lens or standard 8mm?
4. Vandalism potential: Will your camera be subject to damage? Damage resistant cameras are available.
5. Lighting: Is the space well lit or dimly lit. Are the lights turned off at night? Do you want to monitor the area with the lights turned off? Do you need infrared cctv cameras or low light cameras?
6. Budget: Just like any technology, the more you spend, the better the system you get. Keep in mind a low cost camera is better than no camera at all.
About CCTV Cameras: Closed circuit television also known as CCTV is the industry standard in surveillance cameras. CCTV can be a single network of cameras or multiple networks of camera linked together via switches, internet or wide area computer technology. CCTV Video data is analog but can be converted to digital via CCTV Digital Video Recorders. Once the video data is digital it can be managed just like any other computer data and can be stored automatically on computers and network storage devices.

How to avoid being captured on CCTV

Infra-red headset sticks it to the Man

Can't see me now, 'the man'!

Some kooky German artists are intent on showing how to ‘stick it to the man’ by avoiding having your face spotted on the ubiquitous CCTV cameras that record day-to-day life across many of the public and private spaces of our cities.

The URA / FILOART created I-R.A.S.C headset is little more than a circle of infra-red LEDs on an elastic headband, which cause CCTV cameras to flare out the wearer’s face – as pictured here.

From the website: “The URA / FILOART developed device promises to the citizens of a more reliable protection against security measures of the state (and other Überwachenden). IR.ASC bietet die Sicherheit vor der Sicherheit und weist somit auf die Asymmetrie der Kräfte zwischen dem Überwachenden und dem Individuum hin. IR.ASC offers the safety and security has therefore to the asymmetry of power between the individual and Überwachenden.”

While TechRadar is pretty sure you could easily knock one of these up in the shed, we remain to be convinced that wearing one is not going to attract more unwanted attention to you than not doing so.

Which kind of defeats the object.

Remote Access

American Security & Investigations, powered by Iveda Solutions, hosts video and rebroadcasts it to multiple users for remote access via the Internet. Although network cameras can be accessed directly, if there’s more than one person accessing the video, the quality deteriorates. The ability to host simultaneous users is directly related and limited to the available upload bandwidth at the customer’s facility.
Basically, simultaneous users are sharing the bandwidth being utilized by that specific camera. Unless you have an in-house datacenter facility, your site can only support one remote user at a time due to the size of video data.

How Security Camera Systems Work

Security camera systems work via closed-circuit television (CCTV). This CCTV differs from broadcast television because all of the components of the cameras and televisions are linked with cables or alternate direct means. CCTV can be viewed in real-time, and there is no need to broadcast a signal.

CCTV can be found in many places, including airports, casinos, banks, and the streets. Cameras can be placed in inconspicuous or obvious places. There is usually a security room that has individual televisions that are directly connected to a specific security camera. The amount of security personnel needed to monitor the cameras varies with respect to the amount of cameras needed. In casinos, there can be hundreds of cameras.

CCTV has been used extensively in the United Kingdom. Authorities place cameras in car parks and on the streets. These camera placements have significantly reduced car crimes. Authorities in the United Kingdom have been pushing for the introduction of even more cameras. CCTV is very good for crime detection and prosecution.

One draw back of security cameras is that many claim that they are an invasion of privacy. Another argument is that CCTV displaces crime instead of reducing it. CCTV has been accused of being an invasion of civil liberties.

The history of CCTV dates back to when the cameras used in public places were very simple and low quality. Today's cameras have high definition digital rendering and can even track object movement. When cameras are positioned correctly and synched, they can trace an objects movement over a long period of time. Cameras can also have the potential ability to have facial recognition. Currently, high-definition cameras are unable to distinguish faces completely which leads to a plethora of false positives. Critics of facial recognition technology site the potentiality for mass surveillance and the further loss of civil liberties.

Current CCTV technology being developed in the UK and the US aims at creating a computerized monitoring system that would allow security guards and CCTV operators to not have to look at all of the screens. This would allow an operator to run many more CCTV cameras, which could reduce security costs. This type of system does not look at people directly, but rather recognizes certain types of questionable behavior. A drawback of this could be that computers cannot distinguish between normal behavior, such as waiting for someone on a busy street, and suspicious behavior, such as loitering around a car.

Security cameras are very effective for crime conviction and identification, but not as effective for crime prevention. The idea is that security cameras help prevent crime because people are less willing to commit infractions if a camera is in plain sight. The down side to this is that some security cameras are hidden, so criminals have no deterrent. Security camera technology is constantly becoming more advanced, and so security cameras should be able to find criminals, and hopefully prevent more crimes in the future.

CCTV Security Camera: Latest Facet of Modern Life

If you are wandering around the street, window shopping in a mall or just walking your dog in a park, your every move will most probably be recorded by CCTV security cameras.

During the early times, CCTV security cameras were just used in convenience stores and banks where most of the goods and valuable items can be found. But with all the misdeeds, felony and crimes happening round-the-clock in most areas, CCTV security cameras are now being installed in almost everywhere.

CCTV security cameras are said to be a great and powerful instrument used to prevent crime. These CCTV security cameras are put up by business owners, homeowners and the local authorities not just to prevent crimes but to solve crimes as well. These gadgets are mounted unnoticeably on walls, rooftops, posts, stadiums and even in parking lots.

With the emergence of CCTV security cameras in our society, the job of the local authorities, particularly in patrolling a particular area, has become easier. CCTV security cameras serve as a new pair of eyes that are present almost everywhere which keeps on recording the events in the area. Local authorities can just sit inside a closed office while keeping an eye not only on one place but in other places where CCTV security cameras are mounted.

Although CCTV security cameras have proven to be very useful devices or instruments for local authorities, homeowners and business owners, there are still many people who are opposed to its use. Other people claim that CCTV security cameras that are mounted almost everywhere especially in public places can be considered an invasion of privacy.

However, most people do not mind that their moves are recorded. At any rate, CCTV cameras have advantages that will benefit people the most.

CCTV Installation

Success of CCTV Installation

Most people think that the camera that they see is the CCTV system. The CCTV camera is part of the system and is a very important component of it. However, there is more to the CCTV system than just the camera. You must also take into consideration the type of camera you will use, the location where you will place the camera, how the images will be displayed and documented and even the minutest details like the cable that will be used to transmit and connect the video signal to the monitor if it is not wireless.

The installation of the CCTV system can only be considered successful if the requirements needed by the client are met. These requirements have to be considered so that the right CCTV system can be purchased. Where the system will be placed and its end use will also have to be considered. All these requirements will be met once you meet with the company that will provide you with the CCTV system.

As a client, you have to inform the CCTV provider of your needs and requirements. The CCTV provider should be informed of the problem areas where you want to place the CCTV, the type of coverage you need and your budget.

Your budget is probably thee most important consideration so that your provider will help you source the equipment that will fit your budget. Your provider can provide you with a less expensive CCTV camera and source the other equipment elsewhere. You can substitute a colored camera with a black and white one f you want to save hundreds of dollars in the process. The money saved in the monitor can be used to buy other equipment in the system. The CCTV provider can give you a sketch of your CCTV connections and will be able to ensure that the areas that you want to be recorded will have a good view in your CCTV system.

Used CCTV

Using CCTV: For Houses, Businesses and Local Areas

Closed Circuit Televisions or CCTVs are systems that are intended for a limited number of viewers particularly local authorities, homeowners and business owners. These CCTVs are designed to be used together with installed cameras that will transfer images and videos straight to the system. Once the videos and images are transferred, they can be viewed and monitored by people who have access to the CCTVs.

House owners, business owners and local governments are now making use of CCTVs. For home owners, CCTVs are important as they help to keep an eye on burglars. Business owners, however, make use of CCTVs to monitor trespassers. The CCTV is a necessity for local authorities as they help them monitor and observe unlawful citizens. These are just some of the reasons why the demand and use of CCTVs are sky high these days.

Generally, a large number of people have agreed and consented to the use of CCTVs because of the following advantages. First, the CCTV observes the neighboring vicinities so that people living in that area are aware of unpleasant events happening in the area. When that happens, they can coordinate with law enforcers for the easy capture of law breakers. The second advantage of CCTVs is that the equipment discourages unlawful behavior. Once a person discovers that CCTVs are present in a certain area, he will have second thoughts about committing a misdemeanor. There are still other people around who are not convinced that CCTVs really discourage crime. They feel that people are just being more cautious about adhering to the rule of law. The last advantage is that CCTVs can store footage of any incident that happens. CCTVs are also used as evidence during investigations. As a result, misdeeds are being penalized.

Using CCTVs in houses, businesses and local areas are very efficient and convenient to ensure security.

CCTV Camera System - Security with the CCTV Camera System

Security is one of the most important factors you should consider when you have your own business. You can hire security guards to supervise and protect the entire building from bad elements such as burglars. Security guards, though, are only human and they only have one pair of eyes. They may not be able to see everything that happens in every corner of the building at the same time. You will need a CCTV camera system if you are faced with security problems. A CCTV (Closed-circuit television) camera has become the most important element in security. Most establishments like banks, casinos, convenience stores and other places that need monitoring and surveillance use CCTV camera systems.


A study in England showed the benefits of installing CCTV systems in places susceptible to crime. The study revealed that with the help of the CCTV system, the crime rate was reduced by 85% to 94%. The CCTV system makes a community feel safer because security officers can act quickly if somebody is in threat or somebody poses a danger to others’ lives and propery. Installing the CCTV camera system increases the productivity of the crew and staff assigned to keep the security.


If you are planning to install a CCTV camera system, you should know what it is made of. The CCTV camera system consists of either a traditional or wireless CCTV camera, a DVR or digital video recorder, a network card and a monitor for displaying the images captured. You can also add USB outlets so that you can move the videos and recordings to another hard drive and create a back up copy. For a better security system, a manufacturing company has provided us with a variety of CCTV camera system compositions. The manufacturing company created a CCTV camera system that is suited for small and big establishment. A bigger area needs a bigger surveillance system while small areas need only a small CCTV camera system only. The CCTV camera system is provided in 4, 8 and 16 camera systems which consist of CCTV cameras with a variety of camera types, an internet protocol for internet viewing, and cables for easy installation. You may search the Internet for further specifications about the CCTV camera system.
