We have a small business in a plaza which we have decided to open wifi up after having several customers ask about it.

Me and my brother are both in IT but are trying a way to save money. Right now i have 2 extra routers at my disposal. both are older. one is a dlink wbr-1310 and the other is a belkin f5d6231-4….

i also have the router/modem supplied by AT&T which is a 2wire 2701hg-b.

There are 2 computers on the network that i want to keep secure. which i know i can do but also is there a way to block people from being able to see the router ( type the gateway ip into the address bar) for a little more security? Any ideas in any area?

The first video surveillance systems were used by large and medium-sized businesses to monitor for shop-lifting and to keep an eye on cash-handling areas. They have been very effective in identifying and prosecuting criminals. Today, though, more homeowners are installing video surveillance systems. Also called closed circuit TV (CCTV), home video surveillance systems allow homeowners to monitor specific areas and keep an eye on potential thieves, burglars, and vandals.

The monitor is the defining characteristics of video surveillance systems. It receives a live picture from the camera. Normally black and white, the monitors boast higher resolutions than most home televisions, standard resolutions being between 500 and 1000 lines.

Of course, the camera is an important component of the video surveillance system. During installation, the cameras are located strategically outside the home in vulnerable areas like entry ways, porticos, and where landscaping hides access to windows. For a more effective system, cameras should be placed where they are difficult to see. They work continuously, feeding images to the monitor either constantly or at timed intervals.

Coaxial cables tie the video surveillance systems together. Available in many different sizes from local electronics retailers, they transmit the video signal from camera to monitor. These cables come with the video surveillance systems, but there are times when extra longer cables must be purchased for far-away cameras.

Home video surveillance systems also include switchers that allow the user to hook up several cameras to one central monitor. Automated switchers normally cycle through camera stations until it detects movement. When that happens, they lock on the camera where movement has occurred to monitor possible security breaches.

Some home video surveillance systems can be used with VCRs to record the live video feeds. Particularly useful when the family is away on travel, the VCR can record a break-in as it happens, saving a picture of the criminal for later investigation and prosecution. Your home video surveillance system then provides a critical piece of evidence for law enforcement.

Home video surveillance systems make it possible to get the level of security for your home that, in the past, were available only to businesses with large security budgets. Today, they are so affordable that they are used in homes across the country.

If you’ve been looking for a way to better protect your home and belongings, a video surveillance system may be the way to go. One cautionary word: remember that video surveillance systems do not automatically sound an alarm or notify the police or fire department of emergencies when they occur. You’ll still want to have a reliable burglar alarm system. What they will do is provide a permanent image of the crime in progress to make arrest and prosecution more likely.

Your business in Sunnyvale is inviting crime unless you have some type of Sunnyvale access control as well as Sunnyvale video surveillance. Both of them can give you peace of mind when it comes to your business and are easy to install once you use a good locksmith in the Sunnyvale area. A Sunnyvale locksmith can visit your business and take a look at the premises, helping you decide which options are right for you and give you a free quote.

 

There are many different types of video surveillance and access control that you can use for your business. A good Sunnyvale locksmith will be able to help you figure out which type of video surveillance is right for your business as well as help you choose access control. The locksmith should also provide a free security assessment

 

When it comes to Sunnyvale video surveillance, the locksmith will help you decide where you want to place cameras and which type of cameras you want to use. In parking lots, for example, you may want to use Sunnyvale video surveillance that uses cameras that can be monitored and evidence recorded. They are often a good way to deter theft and vandalism as well as protect your employees who park their cars in the parking lot and have to often walk in the parking lot at night. It is always a good idea to try to deter crime if you can by using Sunnyvale video surveillance. 

 

Another type of video surveillance you can use is on the inside of the building. Although the obvious cameras for the Sunnyvale video surveillance will deter crime, they may not stop crime. However, on most occasions that itself is good enough protection. Cameras also allow employees to perform better when they know that they are being watched.

 

 

When it comes to Sunnyvale access control, you need to look towards getting both access control for the outside doors as well as any safe rooms that are in the building. Sunnyvale access control is not just for offices or safe rooms, however. It should also be used to protect employees from intruders. If you have an office that does not require others to be coming in and out all of the time, it is a good idea to protect employees from intruders by installing some type of Sunnyvale access control for your business. An increasing number of crimes are occurring in the workplace. You need to be protected by having some type of control over who comes in and out of the business. 

 

The employee entrance or back door of the building should also be covered with Sunnyvale access control. This will protect employees in the store from those who might try to break in from the back room, especially around closing time. You can never be too cautious when it comes to security. 

 

Access controls mean that employees cannot enter the business after hours, unless you allow them. You can also keep track of individual employees by auditing the access control system. 

 

Look for a good Sunnyvale locksmith that can provide you with both Sunnyvale video surveillance as well as Sunnyvale access control for your business.

Threats of security continue to pervade the global market since September 11. Bombings and threats promising mayhem and destruction had led to a surge in investments around security and surveillance systems. This is fueling the change in how we capture, store, and monitor video.

According to Shivanu Shukla, an industry analyst at Frost & Sullivan “There has been strong interest in being able to remotely monitor surveillance cameras, run video analytics, and integrate surveillance with other physical security systems.”

Shukla notes that network-based video surveillance systems are becoming popular. Frost estimates the video surveillance market to grow from $992.1 million in 2006 to $3956.7 million in 2013.

Analog vs. digital

Analog video surveillance systems consists of analog cameras connected via cables to multiplexers and in-turn connected to monitors and key boards. But what happens when the area that needs to be monitored is a significant distance away and there is a need to record 7×24?

Network surveillance solutions allow existing analog cameras to be connected to a video server, which is connected to the network, and monitored by any computer that is on the network, or the existing control room.

“Storage of the video can be done by network video recorders (NVRs), which can be anywhere on the network, as opposed to digital video recorders (DVRs), which need to be placed close to the cameras or the switcher/multiplexer. In a complete network surveillance solution, network cameras are used to connect directly to the IP network, without the need for an external encoder,” says Shukla.

Video surveillance deployments in Asia are mostly analog based due in part to the market’s price sensitivity. But this is changing as the security threats continue to remain high on radar of both commercial and the public.

Kiran Kumar, a Frost Research Associate, notes that government and transportation sectors are spearheading video surveillance deployments, with large projects for airports, city surveillance, and other critical infrastructure surveillance.

“Fast developing physical infrastructure such as airports, seaports, highways, and rail networks is a key driving force for the strong adoption for video surveillance systems,” says Kumar.

There are three main factors limiting the continuing growth of analog video surveillance systems:

Cost: Set-ups and installation costs of traditional coaxial or fiber-based cabling for analog video systems over large areas is very high. Large-scale projects for city surveillance and monitoring of harbors and ports take a significant role in effecting change to network surveillance.

Scalability: Despite DVRs having improved the recording quality of analog cameras, there is still the physical restriction of its installation near the analog matrix.

Flexibility: Integration of analog video surveillance systems with other systems can be cumbersome. Analog surveillance systems are limited to centralized video analytics, which requires additional hardware, cabling and is difficult to scale.

Benefits of network surveillance

Digital technology is helping extend the capability of surveillance beyond what can be achieved with traditional systems.

Technology now allows us to monitor an area from any location in the world in real-time without any significant investment.

Storage of video can be done on NVRs that can be anywhere on the network. How much video we can store digitally is limited only by the amount of hard disk space. And because the video traverses through the network, backups can be done remotely.

Scalability of network surveillance systems is easy and inexpensive. Network cameras can be connected to the network without rewiring.

With network surveillance systems, intelligence can be distributed either directly at the camera or encoder, or centralized on the NVR or a separate server.

Network surveillance systems are cheaper to build and maintain with reusability of existing IP network infrastructure, highly scalable with little incremental costs, low maintenance costs, and ability to reuse existing legacy surveillance cameras and other display and monitoring equipment as key factors for adoption of digital surveillance techniques.

Limitations of going digital

Not everything is bright and rosy. Due to its dependence on the network, security teams will need the support of the IT department.

“The key challenge to adoption is to get the security and IT teams to adopt network surveillance. Existing network infrastructure makes the proposition of network surveillance stronger. However, organizations where such infrastructure is less developed would be slow to move to network surveillance,” says Shukla.

He concedes that network surveillance adoption is changing the dynamics between the security personnel and the IT teams within enterprises, hindering its adoption rate. The introduction of network surveillance implies the participation of the IT division in security matters.

“Security personnel are typically more conservative and not open to major changes in their environments. Network surveillance adoption would depend on the successful interactions and communication between the two teams within an enterprise,” notes Shukla.

Although Frost & Sullivan expects the trend towards network surveillance to be strong, adoption of analog system will continue to grow as well, albeit slower than network surveillance deployments.

“While remote access, scalability, and distributed intelligence are the key drivers for network video surveillance, price, perceived reliability, and conservative nature of security teams to change and adopt new technologies will hinder adoption,” says Kumar.

Traditionally, cameras have been the point of entry for vendors into the market; subsequently their offerings include DVRs, NVRs, encoders, and software, together with switchers and multiplexers.

Increasingly, due to the emergence of network surveillance solutions, there is an effort from vendors to approach the surveillance solution from the NVR or DVR front, by offering better management software, virtual matrix systems and video content analytics as a solution package.

As traction for network video surveillance picks up in Asia Pacific, providing complete end-to-end surveillance solutions is expected to become a key to succeed in the market.

Daniel Williams asked:

In the past, if you wanted to know what your spouse, girlfriend, boyfriend, or business partner was up to when you weren’t around usually your only option was to hire a private investigator to monitor their every move and record any suspicious activity through the use of sophisticated surveillance equipment. This was and still is a very costly service that can quickly empty your wallet, and your bank account. Even if the information obtained is of little help to you the client, or even worse, useless.

These days who needs a private investigator? Do it yourself surveillance equipment has been around for quite awhile now and just the same as other niche markets the price for these products continue to drop as time goes by making it more affordable than ever to be your own private detective.

What used to be an activity only practiced by the FBI, the CIA, and other law enforcement agencies has now become a vital tool for fighting profit-loss due to customer/employee theft for many companies and small business owners. The use of surveillance equipment in the private sector has also gained interest, especially among the working class where child abuse and infidelity suspicions can be easily confirmed or dismissed through the use of hidden cameras.

The product choices are endless and there are several different ways to monitor any person, place, or thing your heart desires should the need arise. Who, what, when, where, why, and for how long can now be viewed in glorious living color (or b & w if you prefer) and in real-time while the recorded information is simultaneously being stored for retrieval at a later date if you so desire.

The equipment needed to capture and record any type of activity at anytime now only cost a fraction of what it used to! The price of becoming your own surveillance specialist will depend solely on the quality, number, and type of cameras you choose to use and the means by which they store the recorded data.

Hidden cameras, also called spy cams or nanny cams, can be placed inside something as small as a shirt button and can even be built into everyday working consumer electronics items including, but not limited to, video cassette recorders, DVD players, alarm clocks, and portable radios.

Some models even come with a built-in digital video recorder (much like the ones used to capture video on a digital camera but with longer run times) and can run for up to 12 hours using a self-contained rechargeable battery pack. You can even monitor your home or business while away from any pc (high speed Internet connection required) using specialized software that can remotely access your security/surveillance system from any location.

There are a number of reasons why someone would be interested in purchasing surveillance equipment and there are many situations where the equipment is a vital and necessary tool for accomplishing the task at hand. However, most (if not all) states have laws and/or limitations in place regarding the use of surveillance equipment, so know the rules and remember that it is ultimately the user’s and/or purchasers responsibility to ascertain the legality of its use before engaging in this type of activity.

Mark Allen asked:

If you’re in the market for an IP-based video surveillance system, you’re going to need to know exactly what it is you are looking for, and at. There are a raft of technical terms and the like that you’ll have to be aware of. As there is no one definition on what IP-based actually means, let alone other terms like networked or web-based, you are going to encounter as many different explanations as there are salespeople.

At first, video surveillance was all done with analog technologies like CCTV (closed circuit TV), the video being stored on tape. While perfectly adequate for monitoring and recording activity, no broadcast capabilities were present. This made the technology less than ideal for remote surveillance. And of course, tapes involved an inherent time lag. Worse of all, tapes had to be changed on a regular basis, and the quality of captured video tended to be rather poor.

Digital revolutionizes video surveillance

With the advent of the Internet, and increasing prevalence of LANs (Local Area Networks), there was a parallel leap in surveillance technology in the nineties. Analog cameras began to be phased out in favor of digital cameras, the prices of which dropped to within the realm of feasibility for the average person.

With these advances, video surveillance could now be sent out live over the Internet or a local area network. The new digital cameras offered much higher quality, clearer images, which were also far easier to work with. This was a boon to law enforcement in particular.

The basics of IP-based surveillance

In a nutshell, the digital camera “sees” what it is pointed at, and sends the video data over a local area network to a workstation or server. The server or workstation then handles the data. As needed, the data is displayed, recorder or retransmitted to other computers and networks.

There is software available for data analysis, flagging and almost any other data management function you could want. Video surveillance is a more versatile tool than ever thanks to these accompanying advances in software.

Truly IP-based digital surveillance utilizes CCD (digital to you and me) cameras that break up the video data into packets and stream it over the local area network via an Ethernet (Cat 5) cable instead of a coaxial cable. This allows more bandwidth and true TCP/IP capabilities to be dedicated to the video signal.

IP-based surveillance allows better data mining and retrieval, as well as encryption capabilities for your data in the event you need to keep it away from prying eyes and tampering. This is something which analog based surveillance simply cannot offer.

A new development is digital cameras that have built in web servers, meaning no networked computers are required to run the cameras, the video data is sent to the end location for viewing or recording to be played back later. D-Link and Linksys already have offerings on the market already, with many more to follow.

Halfway there

In between the digital and analog worlds is adding a DVR, or digital video recorder to an existing surveillance system. While not IP-based, a DVR system is a step towards such a system. Now, a DVR system may have the same camera and other older analog technologies in place, but stores video on DVR rather than tape. Unfortunately, the poor video quality of the old analog based systems still is a problem here.

If you’re looking at surveillance systems, always ask if digital refers to the recording medium or the cameras. Many companies will call a system digital based on the DVR storage alone, while still using analog cameras.

IP-base recording is highly compressed for easier storage and can be transported over a variety of media

Digital images can be encrypted for security purposes

Updates and add-ons are relatively inexpensive through software packages and Internet computer networking

Adjustable frame rates

Remote or shared viewing may be done over the Internet or a wireless connection

Standard IP video compression techniques are used

IP surveillance cameras may be added individually or in groups according to your needs

If you plan to increase or upgrade video surveillance for your company or home, having a handle on how IP-based video surveillance works will make your decision easier. Video surveillance is headed in this direction; although in the short term it may be a little bit pricier, is an investment in superior quality and flexibility over the long run.
