How to access my security camera from outside?

accessing your camera from the internet

By networkcameracritic 149 Comments

Categories: General

One of the biggest benefits of having IP cameras is being able to access them from the internet. Many of us have smartphones, iPads or netbooks that we take with us and it would be great to check in on the place, a pet or the elderly while at work, in a coffee shop or while traveling. Some cameras have 2 way audio, so you can even talk to the person or pet.

The problem many of us have is how do we do it. We all know that if we go to a certain IP address on our home browser, we can configure and view the camera, but how do we do the very same thing when we are not home.

STEP 1

There’s several steps into making this work, so it’s best to start at the camera. By default, most IP cameras are assigned a temporary IP address by your router. This is composed of 4 numbers from zero to 255 that are separated by periods that is how you find your camera. Then you use a program the vendor provided on a CD that finds the IP address assigned to the camera. You click on that and it brings up the in-camera software that lets you view and configure the camera. The problem with this is that it’s likely that this address will change next time turn off and then back on the router or camera. The first step is to set a fixed address on the camera so that it doesn’t change and you can always find it.

To do this, you will have to go into the configuration screen for your camera and set the option to have a fixed IP address and not use DHCP. Many times, unchecking DHCP will present you with the necessary fields for an IP address, subnet mask, gateway and DNS. This may be overwhelming. The easiest place to get this information is to go on a PC that is on the network and open a DOS window (on Windows, press the START button and then type “command” or on a Mac, run Terminal). In the DOS window, enter the command “ipconfig”, on a MAC enter the command “ifconfig”. You will see the IPv4 address, the subnet mask and the default gateway. Use this subnet mask (typically 255.255.255.0) and default gateway (the IP address of the router). For an IP address, use the first 3 sets of numbers and chose a higher number up to 253 for the last, for example, if it’s 192.168.1.12, you can use an IP address like 192.168.1.100. Just make sure that you do not use the same number twice, it must be unique and not interfere with the lower number that are used by DHCP, so I would recommend you start at least at an IP address of your PC plus 25. For DNS, put either the gateway address or 2.2.2.4 as a last resort.

It will also give you the option of a port number. A port number is what is used to allow a single IP address to have multiple devices. The default is typically 80, but if you want to have more than one camera, you need to use a different number. To avoid port conflicts, it’s better to use a number higher than 8000 but less than 60000. For example, if you have 3 cameras, you can use 10001, 10002 and 10003. From that point on, since port 80 is the default, you must specify the port number after the IP address separated by a colon when accessing the camera, for example if you used 10002, you will use http://192.168.1.100:10002 to view the camera from your browser at home.

STEP 2

Once you have a fixed IP address, the next step is to update your routers firewall with this information. The job of the router is to use a single connection to the internet and allow you to use it with multiple devices like cameras and computers. By default, the router has what is called a firewall and it’s job is to block anyone trying to get into your network including you. You have to define which devices can been accessed from the internet. You do this by going into the firewall configuration screen (sometimes called a Port Forward screen or Application & Gaming) and tell it which IP addresses can be accessed and what port number they are using. Some are as simple as putting in address 192.168.1.100 and port 10002 (start and end are typically the same). Some have separate screens where you define a service. A service is a port number assigned to a name, like Camera2 and port 10002, then in the other screen, you select Camera 2 and specify the IP address, 192.168.1.100. If it asks for protocol, it’s TCP, but if you leave it at the default of Both it doesn’t matter.

Below are sample screens from common routers. While I can’t possibly show you every router, you’ll find that once you find the port forward or firewall screen, the process is simple.

STEP 3

When you are home, you access the camera using what is called the LAN address. This can only either start with 192.168 or 10…, so you know you are using an internal address if it starts with this. To access the cameras remotely, you need it’s WAN address. This is the address that the router uses to connect to your cable or DSL service provider. Any router will have the ability to display this, but it’s much easier to go any PC on your home network and go to http://www.whatsmyip.org. This will display your IP in large numbers on the top of the page. You should now test this, enter the IP and port and see if you can access the camera (ie. http://68.12.123.3:10002). Some routers block the ability to loop back to your own network so it’s possible that this won’t work from home, so try it from a neighbor or friends network and see if you can connect. If it works you can use this to access your camera from anywhere in the world with one caveat, it may only last a few hours or at best a few days, so onto to the last step in the process.

STEP 4

Service providers have many, many customers and it would be very expensive to give each and every one of us a fixed IP address as you did with your camera in step 1. So they use DHCP and assign you temporary IP address and that can change. Some providers set this at once a day, some at once a week, it varies, but you can’t rely on this address to be fixed for very long.

To get around this, there’s a service called Dynamic DNS or DDNS. The way it works is a DDNS company assign you a host name, like myhome.dyndns.com and then your router or camera has the ability to keep this up to date every time your service provider changes the WAN IP address. There are some large DDSN services that are free and I would recommend DynDNS (http://www.dyndns.com). You create an account, pick a domain name from what is free (you can have your own domain name, but not for free), then pick a hostname which is the part of the name you can choose as long as someone else is not using it. Use only one hostname per location, so one for your entire home and maybe one for your vacation home or business.

The best place to maintain this is on your router. Check to see if it supports DDNS and most do. You’ll have to specify the name you chose, your username and password and the DDNS provider you picked. If your router does not support this, many cameras do. ONLY DO THIS ON ONE DEVICE ON YOUR NETWORK.

Once this is set up, you can use this name and port address to visit each camera at home. For example, http://myhomecams.dyndns.net:10001 for one camera and http://myhomecams.dyndns.net:10002 for the other.

If configuring the router is too confusing or not possible, there’s software to do this for you, but at a cost. The most popular is www.PortForward.com. This will only take care of Step2, you will still need to do the other steps and the software still requires the information noted above, so I don’t think it’s a good investment. You can always contact the support group for the router vendor to get help. Don’t contact me as I probably do not have the same router as you and won’t be of much help.

Are cheap food proportional of getting Cancer sooner or later?

Americans Eat the Cheapest Food in the World, But What is It Really Costing?

April 14, 2012 | 74,542 views

By Dr. Mercola

In 2010, Americans spent just over 9 percent of their disposable income on food (5.5 percent at home and 3.9 percent eating out).i

This is a dramatically lower percentage spent just decades ago in the early 1960s, when over 17 percent was spent on food, and even more of a "bargain" compared to 1930, when Americans spent over 24 percent of their disposable income to feed their families.

When you compare what Americans spend to what people in other countries spend, you'll also notice some great disparities.

On the surface, having cheaper food may seem like an advantage, but in reality while Americans may be saving a few dollars on their meals, they're paying big time in terms of their health, and the health of the planet.

No Place on the Planet Has Cheaper Food Than the United States

As reported in TreeHugger, professor Mark J. Perry stated on his Carpe Diemblog:ii

"... compared to other countries, there's no other place on the planet that has cheaper food than the U.S. The 5.5% of disposable income that Americans spend on food at home is less than half the amount of income spent by Germans (11.4%), the French (13.6%), the Italians (14.4%), and less than one-third the amount of income spent by consumers in South Africa (20.1%), Mexico (24.1%), and Turkey (24.5%), which is about what Americans spent DURING THE GREAT DEPRESSION, and far below what consumers spend in Kenya (45.9%) and Pakistan (45.6%)."

Unfortunately, the "faster, bigger, cheaper" approach to food production that the United States has mastered is unsustainable and contributing to the destruction of our planet and your health. Michael Pollan, author of The Omnivore's Dilemma and a number of other bestsellers, said it best:

"Cheap food is an illusion. There is no such thing as cheap food. The real cost of the food is paid somewhere. And if it isn't paid at the cash register, it's charged to the environment or to the public purse in the form of subsidies. And it's charged to your health."

In other words, pay now or pay later. American food may be cheap, but that's about the only "compliment" it deserves, because when you rely on cheap food, you typically get what you pay for.

Why are So Many Americans Fat and Sick?

In many cases, easily the majority, it is due to dietary factors! Millions of Americans live in "food deserts" where fresh produce is hard to find but processed food and fast food is available everywhere. If your meals consist of $1 burgers and super-size drinks, your diet may be cheap, but it is also excessively high in grains, sugars, and factory-farmed meats. This is a recipe for obesity, diabetes and heart disease, just to name a few calamitous conditions that befall those who consume the standard American diet!

You have the U.S. government to thank for this cheap food, as farm subsidiesbring you high-fructose corn syrup, fast food, animal factories, monoculture, and a host of other contributors to our unhealthful contemporary diet. A report comparing federal subsidies of fresh produce and junk food, prepared by U.S. PIRG, a non-profit organization that takes on special interests on behalf of the public, revealed where your tax dollars are really going, and it's quite shocking.

If you were to receive an annual federal subsidy directly, you would receive $7.36 to spend on junk food and just 11 cents to buy apples. In other words, every year, your tax dollars pay for enough corn syrup and other junk food additives to buy 19 Twinkies, but only enough fresh fruit to buy less than a quarter of one red delicious apple.

Heart disease is a direct reflection of poor dietary choices. Heart disease costs us $189.4 billion per year. However, statistics show that by 2030, these costs will triple, resulting in a mind-bending $818 billion!iii Meanwhile, as TreeHugger reported:

"If Americans continue to pack on pounds, obesity will cost us about $344 billion in medical-related expenses by 2018, eating up about 21 percent of healthcare spending, according to an article in USA Today.iv Not to mention the unseen health issues associated with a genetically modified and pesticide-bathed food system."

What's the "Cost" of a Food System Based on Genetically Modified Foods?

The damage is quite simply immeasurable. Nearly all processed foods in the United States contain genetically modified (GM) ingredients, particularly Bt corn and Roundup Ready soy. These crops and other GM varieties are now planted on nearly 4 billion acres of land throughout 29 countries, as their makers (primarily Monsanto, Dupont, Syngenta) continue to praise their worth. These companies, which have created patents and intellectual property rights so that they now control close to 70 percent of global seed sales, extol the virtues of GM crops as though they are a panacea for ending world hunger and solving the food crisis.

But in fact, as a report coordinated by Navdanya and Navdanya International, the International Commission on the Future of Food and Agriculture, The Center for Food Safety (CFS) and others, has stated, GM crops are surrounded by false promises and failed yields, to the extent that they are now destroying the food system with superweeds, superpests and more.

Scientists have discovered a number of health problems -- like changes in reproductive hormones, testicular changes and damage to the pituitary gland -- related to genetically modified foods, however these studies have been repeatedly ignored by both the European Food Safety Authority and the U.S. Food and Drug Administration (FDA). GM foods are typically regarded as equivalent to their conventional counterparts. This, however, is flawed logic because GM foods contain foreign genes that have never before been introduced into the food supply, and are universally contaminated with toxic GMO-specific herbicide residues.

Behind Virtually Every Cheap Burger is a CAFO

It cannot be ignored that the animals raised on confined animal feed operations (CAFOs) pay one of the highest prices for Americans' cheap food. The typical CAFO can house tens of thousands of animals (and in the case of chickens, 100,000) under one roof, in nightmarish, unsanitary, disease-ridden conditions.

Animals raised at CAFOs are treated like objects, not animals -- stuck in cages, overcrowded, often covered in feces -- which is not only hard to watch, but also hard to stomach. It is not at all unusual for animals to be abused in these circumstances; the very conditions in which they live are abuse in their own right. For those who aren't aware, about 80 percent of all the antibiotics produced are used in agriculture -- not only to fight infection, but to promote unhealthy (though profitable) weight gain in animals. Unfortunately, this practice is also contributing to the alarming spread of antibiotic-resistant disease -- a serious problem that is costing tens of thousands of Americans their lives.

CAFOs have been highly promoted as the best way to produce food for the masses, but the only reason CAFOs are able to remain so "efficient," bringing in massive profits while selling their food for bottom-barrel prices, is because they substitute subsidized crops for pasture grazing.

Factory farms use massive quantities of corn, soy and grain in their animal feed, all crops that they are often able to purchase at below cost because of government subsidies. Because of these subsidies, U.S. farmers produce massive amounts of soy, corn, wheat, etc. -- rather than vegetables -- leading to a monoculture of foods that contribute to a fast food diet. As written in "CAFO: The Tragedy of Industrial Animal Factories":v

"Thanks to U.S. government subsidies, between 1997 and 2005, factory farms saved an estimated $3.9 billion per year because they were able to purchase corn and soybeans at prices below what it cost to grow the crops. Without these feed discounts, amounting to a 5 to 15 percent reduction in operating costs, it is unlikely that many of these industrial factory farms could remain profitable.

By contrast, many small farms that produce much of their own forage receive no government money. Yet they are expected somehow to match the efficiency claims of the large, subsidized megafactory farms. On this uneven playing field, CAFOs may falsely appear to "outcompete" their smaller, diversified counterparts."

As it stands, the book notes that "grazing and growing feed for livestock now occupy 70 percent of all agricultural land and 30 percent of the ice-free terrestrial surface of the planet. If present trends continue, meat production is predicted to double between the turn of the 21st century and 2050." Does this sound like a good deal to you?

Allocating More Money to Your Food is Investing in Your Most Valuable Asset...

You... and your family (including those who are yet to be born)! If you want to optimize your health, you simply must return to the basics of healthy food choices. And, as more and more people begin to grasp this concept and demand healthy, unadulterated foods, the more must be produced, one way or another. There is just no way around it -- if you want your family to be healthy, someone in your household, or someone you pay, must invest some time in the kitchen preparing your food from scratch, using fresh, whole ingredients.

Avoiding processed food requires a change in mindset, which is not always an easy task. It CAN be done, however. Rather than looking at processed foods as a convenience that tastes good or saves money, try thinking of it as:

Extra calories that will harm your body

A toxic concoction of foreign chemicals and artificial flavors that will lead to disease

A waste of your money

Likely to lead to increased health care bills for you and your family

Not something to give to children, whose bodies are still developing and in great need of nutrients

Your goal should be to strive for 90 percent non-processed, whole food. Not only will you enjoy the health benefits—especially if you buy mostly organic—but you'll also get the satisfaction of knowing exactly what you're putting into your body, and that in and of itself can be a great feeling. It may cost more to eat this way, but then again it might not. (And in the long run the amount it will save you in the long run is immeasurable.)

You may be surprised to find out that by going directly to the source you can get amazingly healthy, locally grown, organic food for less than you can find at your supermarket. This gives you the best of both worlds: food that is grown near to you and sold with minimal packaging, cutting down on its carbon footprint and giving you optimal freshness, as well as grown without chemicals, genetically modified (GM) seeds, and other potential toxins.

Restaurants are able to keep their costs down by getting food directly from a supplier. You, too, can take advantage of a direct farm-to-consumer relationship, either on an individual basis by visiting a small local farm or by joining a food coop in your area. To find these types of real foods, grown by real farmers who are eager to serve their communities, visitLocalHarvest.org.

Simple Strategies to Eat Well Without Spending More

There are many strategies available to stretch your food dollars while feeding your family healthy foods. Rather than wasting money on expensive cereal boxes and bags of chips, put your money toward foods that will serve your health well, such as raw organic dairy, cage-free organic eggs, fresh vegetables and fermented foods you make at home (fermented foods are incredibly economical because you can use a portion of one batch to start the next).

The following strategies will also make it easier to eat well on a tight budget:

Identify someone to prepare meals. Someone has to invest time in the kitchen to prepare your meals, or else you will succumb to costly and unhealthy fast food and convenience foods. So it will be necessary for either you, your spouse, another family member or someone you pay to prepare your family's meals from locally grown healthful foods.

Become resourceful: This is an area where your grandmother can be a wealth of information, as how to use up every morsel of food and stretch out a good meal was common knowledge to generations past. Seek to get back to the basics of cooking -- using the bones from a roast chicken to make stock for a pot of soup, extending a Sunday roast to use for weekday dinners, learning how to make hearty stews from inexpensive cuts of meat, using up leftovers and so on.

Plan your meals: If you fail to plan you are planning to fail. This is essential, as you will need to be prepared for mealtimes in advance to be successful. Ideally this will involve scouting out your local farmer's markets for in-season produce that is priced to sell, and planning your meals accordingly. But, you can also use this same premise with supermarket sales or, even better, produce from your own vegetable garden.

You can generally plan a week of meals at a time, make sure you have all ingredients necessary on hand, and then do any prep work you can ahead of time so that dinner is easy to prepare if you're short on time in the evening.

It is no mystery that you will be eating lunch around noon every day so rather than rely on fast food at work, before you go to bed make a plan as to what you are going to take to work for lunch the next day. This is a simple strategy that will let you eat healthier and save money, especially it you take healthy food from home in with you to work.

Avoid food waste: According to a study published in the journal PloS One, Americans waste an estimated 1,400 calories of food per person, each and every day.vi The two steps above will help you to mitigate food waste in your home, and you may also have seen my article titled 14 Ways to Save Money on Groceries. Among those tips are suggestions for keeping your groceries fresher, longer, and I suggest reviewing those tips now.

Buy organic animal foods. The most important foods to buy organic are animal, not vegetable, products (meat, eggs, butter, etc.), because animal foods tend to concentrate pesticides in higher amounts. If you cannot afford to buy all of your food organic, opt for organic animal foods first.
