Why You Might Want To Purchase An Outdoor Wireless Security Camera

Buying an outdoor wireless security camera is something that most home owners do not think about. Most folks figure that it is what is inside their house that needs protecting, so they put all of their focus on guarding this area. The thought process is that things that happen outside occur in the open and people wouldn’t dare do things if they think neighbors are watching.
Sadly, you’ll find that having neighbors does not absolve you from having to secure your property. To demonstrate the point, think about how often you really look out your window at your neighbors houses. If you are anything like me, you probably never even notice what your neighbors are doing. Just imagine what could happen when the sun goes down and you’ll quickly realize how beneficial an outdoor wireless security camera can be.
Do you like the car or truck you drive? If you value your vehicles, it might not be a bad idea to protect them with a camera. It is important to get car insurance for these types of issues, but even with car insurance, you’ll still have to repair your vehicle and the criminals will still be lurking out there. Also, insurance deductibles are not always cheap. I would have been much happier had I invested in an outdoor wireless security camera before my car’s windows were shattered in the middle of the day. Even though I was home at the time, I did not notice what was going on until later in the day when I went to drive my car.
Another reason you might want to buy an outdoor wireless security camera is to protect your lawn and the rest of your outdoor property. Do you have a pool,or something else expensive in your yard? When you have items outside the walls of your house, you need to keep a good eye on them. These items tend to get legs much quicker than most. You’ll want to protect if with a security camera as quickly as you can.
You’ll discover that outdoor cameras are not as cost prohibitive as you think. Most of the time, you’ll be able to connect these cameras with your indoor wireless home security cameras. Since these cameras can all connect to each other, you’ll save money on extraneous items. You could even hook it up to your camera monitoring system so that you can see who is at the front door. Front door cameras are excellent for guarding against unexpected guests.…

Wireless in Local Loop [WLL] Emerging Technology

Reasons of Using WLL

Any service provider or organization should strive to provide high quality service in the most economic method available to end-user, the customer.

Telecommunication is no exception and therefore, it is necessary to keep abreast of Technology advancements and innovations to provide the best quality of service at lowest cost possible to the subscriber.

In the last 20-30 years, we have seen switching equipment move from manual boards, Magneto exchanges, strowger etc, to the sophisticated Electronic SPC Switches now in use, viz E-10B, OCB-283 & EWSD etc.

Transmission technology has also advanced, thus far to optical Fibre Cable, Microwave Radio, Satellites Communications etc, and is continuously developing.

The local external Network or the local loop also needs adoption of new techno logies, as it is this part of Telecom Network which accounts for approximately 60% of the total cost of whole, Telecom network. By embracing newer technology in the External Plant, we can maintain a high QOS (Quality of service) and reduce the cost to the subscriber. This means we can offer “Voice and Data Communication” to a much greater percentage of the population, previously denied access (for reasons of insufficient disposable Income) to telephone, Fax and Internet Services etc.

This may be illustrated by:

The average household income in India permits affordable expenditure on Telecommunication services, apportioned across the population, as follows:

Average Affordable expenditure on Telecomm Services

By percentage of population

Rs. 120 per month

25 %

Rs. 160 per month

15 %

Rs. 200 per month

10 %

Rs. 400 per month

5 %

Rs.1000 per month

2 %

And also, the total investment required to install a telephone with conventional Wire Line technology, is approximately Rs.30,000/- to Rs.35,000/-. Looking at the above data/figures, it is evident that cost reduction in the external plant part of Telecom Network is very much essential.

The Radio in local loop, i.e. wireless in Local Loop, if not better service, than Wire Line or Landline, but is an equivalent local loop service compared to wire line services and at lower cost.

The economics of wire line versus wireless are

The cost of installing or Maintaining Wire line systems broadly depends on the cost of Labour (Laying Ducts, digging Manholes) whereas cost of wire less depends on cost of subscriber unit, which tends to fall over time, with increasing economies of scale.

Cost of wire line is more due to use of copper a costly metal in U/G cables whereas WLL is independent of this factor.

Cost of wire line system critically depends on the distance between houses and the penetration levels achieved. These factors are not applicable in WLL.

If a subscriber moves to a different operator in case of wire line system, the investment is lost, whereas in the case of WLL, the subscriber unit in such case is simply removed and installed elsewhere.

The cost of wire line system is incurred, even prior to Marketing to the users, whereas much of the cost of WLL is not incurred until the users subscribe the Network.

The widely used WLL systems are:

corDECT WLL: This is digitally enhanced cordless Telecommunication

The standard is defined by ETSI (European Telecommunication Standard Institute).

CDMA – WLL: An American System as per IS-95.

Requirements for a Wireless Local Loop System

The WLL must provide all services supported by the wired local loop with the same or better quality.

A Wireless Local Loop (WLL) system is meant as a replacement for the traditional copper twisted-pair local loop. The WLL system is expected to provide a superior alternative to buried cable. The main purpose of the WLL system is to substitute a wired local loop for providing fixed telephone access. The WLL must, in general, provide all services supported today by the wired local loop, and also those, that are likely to emerge in the near future. Further, it must provide these with the same, or better, quality.

The requirements of a WLL system can be broadly divided into five categories: services, capacity, PSTN connectivity, cost and maintainability.…

Wireless Headset Technology From Past to Present

Wireless technology is best known for making history in 1969 when the technology transmitted the famous first words from the moon “That’s one small step for man, one giant leap for mankind”. Since then, it has come a long way in the field of communications technology. These are now the choice for air traffic controllers, 911 dispatchers, the New York Stock Exchange and many other businesses that rely on wireless headset technology.
Headsets come in a number of models which allow you to:
• Integrate PC and desk phone communications with one wireless headset
• Unify PC and mobile communications throughout your office
• Connect to desk phones with performance, style and comfort all in one wireless headset
• Use a handset lifter for remote call answer and end capability
There are a number of wireless headset models which are both versatile and flexible. Compatible with most phones, light weight models provide up to 10 hours of talk at a time and those with small base stations can also be used as a charging station when you are not using the headset. Most batteries are a lithium ion polymer that can be fully charged in 3 hours. The life expectancy of most batteries is 1 to 2 years.
They offer a number of features that businesses will find extremely beneficial, including a good range – the user can walk or roam up to 300 feet from the desktop phone. The 1.9 GHz voice frequency was developed to eliminate interference and static humming no matter whether you are close or far from the base unit. A 64 bit digital encryption signal will ensure privacy at all times.
Some of these have up to four microphone options and four speaker controls to enable a better range and ability to fine tune the system to your personal phone and volume needs. Look for an up and down switch for setting the microphone sound level which will allow you to modify the level of sound and allow the person on the other end of the line to hear you better. Also look for a knob on the side of the base unit that will allow you to adjust the phone’s clearness.
These are also designed for comfort. There are several headband adjustments and ear pieces to choose from. The earpiece can be worn over the ear, over the head or behind the head using a neckband. These ear pieces can be used without the headband and weigh less than an ounce, making them ergonomically designed for comfort.
Ultimately, look for a well-known, highly trusted brand that provides superior wireless headsets. You want to find a versatile wireless headset than can be used in a number of environments including businesses, offices, at home or for personal use.…
