by Dong Ngo
Trendnet TV-IP512WN Wireless-N Camera

--------------------------------------------------------
If you're looking for a wireless security camera that supports the high-speed Wireless-N standard, Trendnet has something for you.
On Tuesday, the company announced its Wireless-N Internet Camera Server with 2-Way Audio, model TV-IP512WN. Essentially, this is a Wireless-N security camera that you can assess and control over the Internet without any additional equipment--thus the "server" moniker.
According to Trendnet, the TV-IP512WN supports throughput speeds up to 300Mbps and provides up to four times the coverage of comparable Wireless-G products. Its two-way radio feature means you can communicate with the person standing in front of the camera from the remote location.
The new TV-IP512WN comes with a free software suite that can manage up to 32 Trendnet security cameras with some advanced features. Examples of these features are multiple various-shaped, motion-detection-recording windows; event-driven e-mail alerts; scheduled recording sessions; MPEG-4- and MJPEG-image compression; and advanced hard drive storage-allocation tools.
The TV-IP512WN supports Wi-Fi Protected Setup, meaning adding it to a wireless network is as easy as pressing a single button. It has input/output ports that can be hard-wired to third-party alarm systems.
The camera also comes with a removable CS lens and features 16x digital zoom. It has a built-in SD card slot to store images on an SD card.
The Wireless N Internet Camera TV-IP512WN will be available for purchase starting May 1, with an estimated price of $250.
Have Secure House By Using Burglar Alarm
Motion Activated Security Camera
Monitored Security System%s are great if you don’t want to store 24/7 video footage. By using a motion activated security camera, you will only record when movement is detected. This way you will save lots of storage space. Since all modern Home Alarm Systems are using hard drives to store the video data, by using motion detection security cameras you will be able to archive a longer period of time on the same storage device.
Considering areas where movement is a sign of danger or intrusion, you will sometimes reduce the disk usage to as low as 10%.Using such a system, you can afford to store high quality images or videos and not be afraid you will fill your storage device. If you take periodic backups on DVD or magnetic tapes, you don’t have to think of a new backup that often.
Types of motion activated security cameras
Most motion activated security cameras are IP cameras. That is because a certain amount of computing is needed and only IP cameras are advanced enough to handle the task.
The actual movement trigger can be accomplished using two methods:
l A standard optical sensor (like those used in classic security systems) will signal the camera when to start recording, based on its input.
l The IP Camera’s software constantly compares recorded frames and only starts the recording when two consecutive frames are different (e.g. something moved). The recording will stop when two consecutive frames are identical (nothing is moving anymore)
Motion tracking
Some motion activated security cameras have a great additional feature: motion tracking. The camera is mounted on stepper motors that provide tilt and pan features. A software component in the camera detects movement targets and sends electrical commands to the motors so that the camera will follow the movement target. This feature is only available on advanced cameras, but it might be very useful if you are monitoring an important target.
What to do if you need the feature but don’t have a motion activated security camera
If you have a standard security system that is eating away all your disk space with useless recordings, there’s still hope. You just need to change the software on the computer that is recording everything.
Or, if you’re not using a computer, just replace your current storage device with a standard computer. You will find software like motion or Zoneminder that will handle the entire motion detection feature even if you have standard security cameras. These computer programs even allow the user to ignore certain areas, like the window facing a busy street, that aren’t important movement events.
If you want to setup a good Home security system, you certainly need motion detection. You will use a lot less disk space for video recordings and you will clearly identify movement events.
Home Security with camera for Home safety, kids safety and family watch
A home security camera helps parents monitor what is going on at home while they cannot be present.? It provides elderly family members with the ability to be independent longer that they would be otherwise and helps to present unwanted intruders in the home.
Most parents really would prefer to be at home when the kids are coming home after school.? However, that just is not always possible. Work, lessons, and distance often makes it impossible to be in the home at all times when children are present.? There may be a nanny, housekeeper or babysitter available, but parents sometimes want to see for themselves what is going on in the household when they aren’t around to supervise.? It may be that the youngsters need to know that mom or dad will be checking on them to make sure they make it home on time, or that they are completing chores that are needed.
?
Having a home security system with a camera means that no one can be in the house when they are not supposed to be present.? This can include those who are present to try to burglarize the home or the parents may not want children from other families in the house when there is no adult supervision.? Conversely, there is the whole issue of the quality of the child care being provided by paid employees in the home.? The housekeeper or nanny may not be paying enough attention to the needs of a very young child.? They may be overly forceful in their punishment or discipline of the child, sometimes even to the point of injury.? With a home security camera, the parent can check in visually several times during the day, or as often as they want so that they can check on the child and the caregiver unobtrusively and confirm that everything is okay at home, or intervene if necessary to protect the child.
?
A similar situation occurs in a home when there are pets such as a dog or cat that stay alone in the house while you are out working or on a recreational break.? A recording device played for them while you are out, or a camera recording of what they are getting into.? This is not to say that the dog and or cat are misbehaving, it’s just that many refuse to obey your commands if you are not there to enforce them. Having camera surveillance of your pets can be a way to protect them if they are venturing into situations that could be harmful or fatal to them.
?
If there are elderly family members who live in the home, or even in another residence, a home security camera is ideal for monitoring their well being. Help can be sent in the event of an incapacitating illness or when there is a fall.
?
Of course, an obvious reason for setting up a home security system with a camera is to prevent unwanted intruders into your home.? In many cases, the alarm alone will be enough to scare off the intruder, but a camera, alarm and tie in to a response unit will be a great way to prevent loss from theft to your possessions. Alarm systems for home security usually include notification of inhabitants for fireFeature Articles, smoke and noxious gases as well as intruders.

Advice On Choosing The Best Security Camera - Resolution
Advice On Choosing The Best Security Camera - Resolution
With so many choices of surveillance cameras in the market, it is easy for a consumer to get overwhelmed in choosing the best security camera for their system needs. No matter what type of surveillance application you are installing, there are some basic things that all consumers should consider in order to make a good choice. This will be the first of a series of articles to help guide a non-technical person that is researching the purchase of a surveillance system. The main topic for this first article of the series is security camera resolution.
It is important to know what resolution means when shopping for a surveillance camera. CCTV cameras have a resolution range from 330 TVL (television lines) to 600 TVL. For color resolution, CCTV cameras max out at 560 lines, however you can get black and white CCTV surveillance cameras in 600 TVL. IP security cameras are now available in much higher resolution, up to 5 megapixels. What does this mean?
In the United States, regular TV transmission (not high definition) displays 480 lines of resolution. So it is possible to purchase CCTV cameras that can record equal to or greater resolution than TV. Obviously the higher the resolution of the camera that you choose, the more detail you will see in your surveillance video. High definition television (HDTV) displays either 1080 or 720 lines of resolution depending on the channel and the type of HDTV that you have. In order to get higher resolution from surveillance cameras, the only choice is IP based megapixel cameras, which connect over an IP network instead of a closed circuit. Generally, IP mega-pixel cameras are much more expensive than CCTV cameras. For high end applications that demand ultra-high resolution, megapixel cameras can capture surveillance video at more than twice the resolution of high definition television.
Some people that are shopping for a security camera are unrealistic (because of their lack of experience) about what a surveillance camera can capture (especially CCTV cameras). I will go into more detail about lens types and sizes in the next article in this series. I must touch on it briefly now as it is so closely related to resolution. For this example, we will use a 3.6mm lens which gives you about a 90 degree field of view outward from the lens. Some people think that if you take a 480 lines of resolution camera with a 3.6mm lens that you will be able to get a clear picture both of an object that is 20 feet away and an object that is 80 feet away. This is not true. While the 3.6mm lens will easily pick up the object in detail at 20 feet away, it cannot pick it up at 80 feet away also with the same 3.6mm lens. In order to pick up the object at the further distance, you have to either use a larger lens that would make the image appear more close up or use a high end megapixel camera that would allow the operator to zoom in digitally without distorting the picture. Digital zoom is possible with high end megapixel cameras, but not with normal resolution CCTV cameras. Because of the huge price difference between CCTV and IP mega-pixel cameras, a lot of times it makes sense to add additional CCTV cameras instead of upgrading to megapixel cameras. This will lead us into the next article which will be about understanding and choosing the right camera lens.

Your Guide to Hidden Cameras and Other Security Cameras
Hidden cameras have become very popular in recent years with business owners, law enforcement officers and parents. Business owners often use surveillance systems to keep an eye on employees or their store to protect the business from theft or abuse. Hidden cameras are used by the police to catch criminals in the act or to record arrests as they occur. Parents use nanny cams to make sure their children are being properly treated. If you’re thinking of buying a hidden camera or other type of security camera, here’s a quick guide below.
How Hidden Cameras Work
There are two types of hidden cameras - wireless and wired. Wireless hidden cameras use batteries and have the camera and transmitter concealed with no visible wire from the camera to the recording equipment. Wired cameras will have a physical wire running from a VCR or PC to the camera.
To determine if you need a wireless or wired hidden camera, consider the length of time you will need to record. Will the batteries hold up long enough? The location of the hidden camera is also important. Hidden cameras come in a variety of shapes, forms and themes. Choose a camera that goes well with the environment around so it will be unnoticeable. Some cameras feature wide-angle viewing, which comes in handy when you need to survey a large area. Also, the lighting of the area is important. Check the hidden camera’s resolution before buying.
Types of Hidden Cameras and Security Cameras
There are many types of hidden cameras and security cameras for all situations. From dummy cameras to professional cameras, each one serves its own unique purpose. Here are some types of cameras and their benefits.
Nanny Cams
Protect your children throughout the day with a nanny cam. Even if you have a nanny you feel you can trust, it doesn’t hurt to have a nanny cam for the safety of your children and home. Nanny cams are actually hidden cameras that come in many shapes and sizes. The camera might be embedded in children’s items such as teddy bears, backpacks, baby wipe containers, dolls, stuffed animals, etc. These items can be placed in the child’s room along with other toys. There are also nanny cams for other rooms of the home, including clocks, radios, table lamps, food containers, thermostats, pillows, picture frames, hair dryers, DVD players, etc. Every room can have a nanny cam if needed. Check with your local law enforcement before getting a nanny cam or hidden camera for your home to be sure there are no restrictions.
Surveillance Systems
If you need more than a few hidden cameras, consider a surveillance system. Surveillance systems enable you to observe multiple locations through one sophisticated system. With a channel DVR system, hidden cameras are set up in different areas and interconnected so you can survey all the areas through multiple channels. You can expand your surveillance system as your business or operation grows. There are also portable DVR surveillance systems and those that enable you to monitor the area from any location online.
Monitors
Monitors are screens that show what is going on as it happens. Many public places have monitors set up to let people know they are being recorded. Some monitors are used by the owners or security guards to keep an eye on areas from behind the scenes.
Dummy Cameras
Dummy cameras are not hidden cameras or even real security cameras. They look like real security cameras and give an appearance that the area is being recorded. The thieves won’t know if the camera is real or not. Dummy cameras are often used as a deterrent by many business owners.
Professional Cameras
Professional cameras are often used to survey large businesses or offices, inside or outside. They can be mounted on walls or ceiling brackets. Some are waterproof for outdoor surveillance. A variety of professional cameras are available for different situations.
Hidden cameras and security cameras are great for protecting your children, home, business or property. Use the guide above to find the hidden camera or security camera that’s right for you.
