The major benefit of a wireless CCTV camera is the ease of installation and time saved by not having to run wires through the home or business. They can also be moved when the need arises, and can even be used for covert operations. Many times, the need may arise for a camera to be installed, but due to the location and circumstance, it not be convenient to run wires from the installation site to the recorder or monitor. AS the time taken and activity to run wires may cause you to miss the opportunity to catch a person conducting themselves in an illegal manner. By installing a wireless CCTV camera, it can be done quickly and conveniently.

Wireless CCTV Cameras are a combination of several components: A camera, a transmitter, and a receiver. A Wireless Camera transmits video from a built-in transmitter to a receiver, which is in turn plugged into either a monitor or other recording device. They operate at different frequencies, 900Mhz, 1.2Ghz, 2.4Ghz, and the top of the line 5.8Ghz. Each frequency has it’s own specification and operating guidelines.

900Mhz
Four channels are available in this band and it has an operating distance of 200 to 700ft depending on environmental conditions. The receivers must be tuned to get a clear picture.

1.2Ghz
High resolution video transmission and outdoor medium range potential, a good choice for multiple system applications. This frequency makes a huge difference in the range and quality of video image received, especially when used in buildings. If Used in a clear site without visual obstruction and with no electrical interference, you can expect to transmit up to 300 feet with good clarity.

2.4Ghz
A 2.4 GHz Wireless CCTV Camera comes equipped with 4 channels with no tuning required. We generally recommend 2.4 GHz over 900 MHz because the overall video quality is better. Range varies from 200-700 feet, depending on environmental conditions. Many cordless phones also operate on this frequency and may cause interference, if placed in close proximity to a Wireless Video Camera.

5.8Ghz
The latest in CCTV Wireless Security Equipment. It has 4 channels of video with an operating frequency between 5725 ~ 5825 (4 Channels). At this frequency, you are not sharing part of the public band, which eliminates interference from other 2.4 GHz devices. Plus, a 2.4 GHz Wireless Video Camera may only transmit a wireless signal up to 500 feet line of site, whereas a 5.8 GHz Wireless Video Camera sends a stronger signal up to 2,000 feet line of site.

wireless cctv Camera can easily be installed by mounting at the desired location and plugging in the the receiver to your monitor or computer network if you have a wireless network camera installed. The other factor to consider is a power source, which can vary from a wall outlet to batteries. The power of a Wireless CCTV Camera is in its flexibility and ease of use also to the degree that it can be hidden from public view.

Motion Detector Security Camera comes in many different size and forms and are used in a variety of ways; but mostly for covert operations in areas where there is suspected criminal activity.  An example to this is the nanny cam that has become very popular today mainly because it is very helpful in catching employees in the act.  The whole idea behind using a security system such as this,is to place the camera in a position that is hidden but will only record if there is activity or motion.  With modern IP technology remote viewing and recording can be standard features.

Asset Protection
In today’s world it has become increasingly urgent to put measures in place to protect ones assets and to monitor the activities of employees in sensitive and remote areas or areas where there is no visual supervision.  The Motion Detector Security Camera can be the ideal piece of equipment for the job as it is a unit that is triggered by activity and will only stay on with activity present.  This is especially useful if you are recording the event to view at a later date as data space will not be used until there is motion.  It will also alert you if some one enters a restricted or sensitive area.

With a Motion Detector Security Camera you are able to detect and record motion by way of software application and a DVR (Digital Video Recorder), which is activated by a signal from the security camera or motion sensing device on the camera. The sensing of motion triggers the DVR which then records the events as they take place.  Such security systems can use different technologies to perform this task, they include infra-red, ultrasonic as well as microwave and even dual technology motion detection.

If you use the infrared Motion Detector Security Camera the detector would sense the infrared radiation of the area that it is viewing. If a human or animal passes through the area, the detector will see the change in infrared frequency and trigger the camera to begin recording the event.

In the case of an ultrasonic Motion Detector Security Camera, the sensor works by producing ultrasonic pulses that when disturbed, sets the camera rolling.  However, such motion detector security cameras are not able to work properly other than in clear surroundings and in case of obstacles, the ultrasound signals are distorted and thus, functionality of the system is hampered.

The microwave Motion Detector Security Camera works by way off a microwave transmitter and when the waves encounter an object, the waves are reflected back to a detector which in turn activates the camera system, and though such a motion detector security camera is better than the ultrasonic one, it can still suffer from false alarms because it will capture minor movements that in fact do not warrant any kind of alarm being set off.

To combat the problem of false alarms, manufactures have introduced the use of the dual technology motion detector security camera. It works on infrared and microwave motion technology, this has reduced the false alarm levels as the detector needs two trigger events to activate the security camera and in fact, this kind of Motion Detector Security Camera will probably be the most popular of all motion detecting security systems in the times to come. And may well replace the other types of motion detecting security systems being used at present.

Criminals do not work a 9 to 5 job,  many seek the cover of darkness to conceal their illicit activities, they target locations with high value items, low human activity and areas isolated from prying eyes.  This is when the Night Vision Security Camera earns its stripes.  Night vision cameras are an excellent tool for viewing areas in the dark without a normal light source.  Most  CCTV cameras can operate in both daylight and at night with the aid of an infrared light source.  There is an increase in use of these low light cameras for more pleasurable activity such as filming night creatures without disturbing them with bright lights.

There are basically three types of night vision security cameras, infrared, thermal infrared and passive night vision.

Infrared
Infrared security cameras comes in two variations with the most common commercial type being the low light camera with infrared bulbs attached or in a separate housing.  These night vision cameras will operate in total darkness and have sharp clear vision although in black and white.  They are available in many formats, wireless or with coax cable to the IP version using CAT5 cable. Their cost is now more affordable to the house user.

Thermal infrared
Thermal Infrared imaging systems have come down in cost over the past few years to the point where they are affordable to just about any company out there.  In days gone by Infrared camera systems were expensive items that required cryogenic cooling with liquid nitrogen of the detector in order to operate.  Thermal infrared imaging systems now are self contained and require minimal maintenance to operate efficiently.  But are mostly for commercial use as the costs are still prohibitive for most household users.

Night Vision Passive Night Vision
Passive night vision devices are light gathering and amplification devices (called tubes) that are attached to the lens of Night Vision Security Cameras.  They are powered by the camera power source or by battries.  They require no light except what ambient light there is as per star light, hence the name starlight scopes.  They produce an eerie green image; in the older generation the image was also grainy, but with 3rd generation scopes the image is quite clear. They are more for specialized use, usually by government agencies and now by commercial and private boat captains that find them highly useful at sea.

Of the three, the infrared camera is the one that is mostly used as a Night Vision Security Camera as they are the most affordable, the easiest to setup and maintain and comes in many varieties, styles and format.  With wireless and IP capable systems, a net work of cameras could be set up around a house and be hooked up to your computer in less time than it takes to roast a chicken.  Not only will you now be able to see the night creatures prowling around your house and turning over your garbage can, but also if you left the sprinkler on in the back yard.

CCTV Camera Systems the traditional analogue surveillance technology has been used for over 2 decades, and it is rapidly being replaced by the more efficient digital I.P. technology surveillance camera systems. The combination of the computer technology and CCTV has created a powerful tool.

I.P. or Internet Protocol is the most widely used system for communication over the internet and computer networks. An I.P. address is a unique 32 bit number assigned by the Network Information Center that permits I.P. networks to communicate with each other, from any where in the world.    The I.P. address is divided into three parts, the first part designates the network address, the second the subnet address, and the third the host address.

The I.P. CCTV Camera System creates digitized video streams, which are transferred over a computer network, enabling remote monitoring from anywhere within the reach of the network and also viewing from remote locations by way of the Internet. This technology has many advantages over traditional CCTV systems.

Cost:
Most CCTV Camera system will integrate with your present computer system and does not require any extra hard ware like VCRs, monitors, switches or joysticks. Maintenance cost is also quite lower as equipment servicing is not required.  I.P. systems can work with an existing analogue one, as it can be configured to receive the same video and alarm signals as the analogue system. Since both are capable of independent operation, there is no need to dispose of existing equipment until you are ready to expand the I.P. CCTV Camera system, thus saving on initial installation and equipment costs.

Flexibility:
The system allows remote access to areas without a power source. It has simplified user interface from a computer by way of a key board and or a mouse.  Expandability without great infrastructural cost is a key factor and it is not brand restricted as all use the same protocol.  I.P. Surveillance technology can be readily integrated into other functions and security services, since the digital video feeds can simply be distributed into other networked systems, e.g. access control, intranets, alarm systems, etc.

Images:
Are of a higher quality due to the use of digital cameras, digital processing and storage. Digital technology allows no degradation of images over time as with older magnetic tapes. Storage can be on your computer external hard drive or other computer data storage source, including DVD disks.

I.P. CCTV Camera Systems is the way of the future as it offers the highest degree of flexibility and integration at the least cost. It is adaptable to most all situations that one can think off.  It has changed the architecture of the CCTV security camera design concept.
