Convert A Webcam Into Surveillance System - Install a Wireless Module -

This article is the third in a series detailing how to convert a webcam, also recognized as an IP camera, or an Internet camera into a complete surveillance and security system. Add lights, motion sensors, outdoor enclosures, wireless adaptors and even portable Internet cards to an Internet (IP) camera and you have an ingenious, yet cost-effective electronic security personnel. These can be perfect for watching out on holiday homes and RV's, remote job sites, outdoor businesses, such as quarries or power stations, stored equipment, or even as remote outdoor webcams. The first step was to add a Passive InfraRed (PIR) detector to the camera to trigger it to transmit alerts and to upload pictures or videos of the activities that sparked the detector. The second step is to add a flood lamp to discourage would-be mischievousness or stealing. The 3rd step requires linking a wireless module so that the cameras can be installed without the demand for data or video cabling.

A webcam is a video recording camera which feeds its images in real time to a computer or computer network, oftentimes via USB, ethernet or Wi-Fi. Their most popular use is the organization of video links, permitting computers to perform as videophones or videoconference stations. This popular utilization as a camera for the web presents the webcam its name. Other common uses include security surveillance and computer vision. Webcams typically have a lens, an image detector, and some support electronics. Many lenses are readily available, the most common in consumer-grade webcams being a plastic lens that can be placed and removed to set the camera's focus. Fixed focus lenses, which have no features for adjustment, are also in the market. As a camera system's depth of field is greater for small imager formats and is better for lenses with a large f-number (small aperture), the systems used in webcams have sufficiently large depth of field that the utilization of a fixed fo cus lens does not impair image sharpness a lot. Image sensors can be CMOS or CCD, the first one being dominant for low-cost cameras, but CCD cameras do not actually outperform CMOS-based cameras in the low cost price range. Many consumer webcams are capable of providing VGA-resolution video at a frame rate of 30 frames per sec. A lot of newer devices can make videos in -megapixel resolutions.

Support electronics check the image from the detector and beam it to a local host computer via Ethernet cable or wireless bridge, letting a wireless connection to the server computer. If a local server computer is not ready, the cameras can be connected to the Internet directly, using the general wireless Internet cards, such as 3G and 4G cards from suppliers such as Verizon and Sprint. Some more powerful cameras have integrated processors that add a number of features, such as motion spotting transmission, email sending, regular transmittal of still pictures and videos. Some can even include still photos and video images within email alerts. A lot of webcams possess internal microphones.

Add wireless connection (WiFi) to the camera. A wireless network normally is not wholly wireless because some piece of equipment will probably be connected to the internet source by line (cat 5 or cat 6). That link depends on your equipment and the service type. Some internet modems have wireless router capability "built-in" but in that instance the modem will still be wired to your wall or where ever the internet goes into the room. You'll also be linked to the electrical outlet. What you receive depends on what type of service you get, who provides it, and what equipment is provided.

The efficient distance between the cameras and the wireless Internet access point varies because of surroundings and ability of the equipment. Presently the range can be up to 300 feet for some gadgets without "extra help" but on the average many fundamental systems are rated as up to one hundred fifty ft. Closer usually implies improved signal strength and video quality, but not all the time. Other factors like metal I-beams, cordless phones, wireless remote controllers and other electronic devices, among other things, can affect the quality of a signal. There are wireless extenders/relays available that can widen the range of a wireless signal. Some are in the kind of a high-powered antenna, some are similar to wireless adapters and are connected into a power outlet along the way to a computer faraway. So the device relays the wireless signal to the other computers. Wireless connection can be accommodated to computer peripherals, such as an IP, or Internet camera. This c onfiguration allows the cameras to be set up hundreds of feet away from the Internet access point. One such camera is offered by Offsite Commander Systems.

Threats Introduced by Wireless Networks - Education

The following threats are present wherever wireless networks exist:Attacks can be of any type that Windows XP Professional could be launched from a wired connection, including password-cracking attacks, attempts to find weak controls, broadcast monitoring(whereby an attacker sniffs data as it traverses your network), or even the launching of a worm, virus, or Trojan horse attack. While use of a switch instead of a hub as a connection point for the wireless AP might prevent casual listening to all traffic on the network, Address Resolution Protocol (ARP) spoofing can be used to trick the switch into routing data through the intruder's client.Even if the intruder means no harm and is just seeking free access to the Internet, if his computer is infected with a worm or virus, he might spread it to your network.This type of attack might be accomplished by an attacker against wireless networks that rely on SSL VPNs for access security. In this attack, the intruder uses an ARP sp oofing technique and attempts to substitute his server credentials. The client gets a warning that the credentials have changed and is asked to accept them. If a user accepts the credentials, the communications destined for the client's internal network are now redirected to the attacker's rogue server.Unauthorized connections by anyone with a computing device and a wireless network card to an unsecured wireless access point Access to the wireless network does not require a wired connection MCP certification.A connection to your wireless network might be made just as easily from the parking lot of your building, thesidewalk outside its front door, or the offices on the floor above as it is from your business offices. While a wireless connection does not remove the protections you have in place using authentication, access controls, and encryption, a wireless connection does allow unauthorized individuals access to your network, inside your firewall. Any connection to your in side network is a potential threat.Attacks on your wireless clients from other wireless clients Joining your wireless client to an unsecured wired network places you on a network withunknown participants. This is like being connected to the Internet without a firewall. Any attack that might be mounted over the Internet can also be used against clients on a wireless network.Attacks from rogue access points that have created unauthorized access points to the network Employees might connect a wireless access point totheir authorized network connection. They do this to make it easier to move around the general area of their office without a wire or to allow visitors to their area to connect to the network. An intruder might seek to connect a rogue wireless access point to an unattended network jack. If the intruder is successful, he now has a connection to your network from outside your facilities.An attacker might attempt to capture logon credentials by placing a fake access po int near the legitimate one. If her access point has a stronger signal, she can entice clients to attempt to log on to her wireless network instead of the real one. When clients attempt to log on, she might be able to capture logon credentials that can be used in an attack on the client's real networks.

Google service convenience brought security hidden danger - Business

This article will express is about the author in the use of the system with two asus Eee Pad login Google service process found some questions. These problems can let us to this new product produce some new feelings and views.

When the author attempts to use Google account login, but found no connection to the web. The author's first reaction is to be linked to the public the wireless network, but found department just changed office area, and forget the new WPA2 password. Then, the author opened his Virgin Mobile Mi-Fi 2200 personal access equipment. Then the author in the Eee Pad for hot list, but to the surprise of the author, Eee Pad have found the Virgin hot spots, and has successfully access. The author has chosen just now is hot and enter the code? The answer must be wrong.

The authors of the study show the author noticed more problems, Eee Pad can not only be found and connection of the Virgin Hotspot hot spots, and even the authors of the other lists commonly used hot name, including the author in camping sites (45 minutes drive from distance office) the use of WiFi Hotspot, are found in the Eee Pad hot list. This phenomenon is the only explanation, Google not only stores we once visited the hot spot of the name, will also access password also were stored.

In addition to the obvious about personal privacy issues outside, still a potential problems. Some may think of, if you use the andros application, and also used Google services, then you may be not the knowledge of the state of the accepted andros system hidden function. But we actually use, many WiFi hotspot and we did not build, among them were some when use may need additional special conditions, so we are not generally will WiFi access point password told the third party. This is a very easy to understand is also widespread security strategy, but like Google to not pay any attention.

According to understand, for most andros system users, not quite clear how to ban andros operating system will WiFi access point name and password sent to the Google server to back up, and in the user use any other system based on the equipment and two login Google account to be automatic synchronous these data. If it is really so, then Google to the way users have only two: either don't use login encrypted andros equipment wireless network, or in violation of the agreement of the encrypted network, will share with Google password. And for those who wireless access points for managers, the most direct reaction may be banned those who adopt the equipment access network andros system. Such as the company USES is with a password protection of the wireless network, if any staff use andros equipment can send your password to the wireless networks will Google, it is the company network managers situation that is not acceptable. If want to make refused to login strategy, and so o n is not limited to the external personnel, but most of the company include his staff.

Recently on some blog we can see, many Internet users think that future life is built on Facebook, Google and Apple company developed under the various rules, and that will only make originally in Microsoft empire period the darkest days look also appears kind and not so dark, because such as Facebook, Google and other companies in the treat individual privacy exposed more than Microsoft more serious problem. We think these fears are valid, and the concern if not solved, there will be serious security problems. Just think, if has the unlawful molecules through the equipment to be automatic access the andros we the company network, and the damage is immeasurable. From this problem can also see that Google's engineers and programmers and project director in processing enterprise sensitive information and the protection of data privacy lack of basic cognition. In fairness, if can choose only one data don't be harvested, backup or in different between equipment synchronous, th at this kind of data should be password. For this, we have to wonder, Google also collected exactly what type of data, to help us better experience Google services "value-added".

Because, this is Google's a "function", and this function really is very convenient, especially for those who don't know the protection of privacy or are willing to sacrifice part of privacy for the convenience of the customer is higher. And this is what we worry about the most. But many users do not know the convenience brought about by the potential risk.

For Google's this way everybody should be how to treat? This is a careless up like that? Google will really heartfelt consider for the customer? Are we too indulgence Google's behavior, or Google themselves across the our bottom line? If readers found that is not like this article that said in the article comments can also give your opinion.

Although, at present, we have found the problem only appear in the purchase the asus Eee Pad Transformer, and in other before andros equipment, still did not pay attention to this problem. Therefore, we can also suspected that this was the Honeycomb zhuo the new functions of the system is the result of.
