Security Camera Systems – 5 Valuable Tips to Selecting Security Cameras

When selecting the best security camera system possible for your home or business it is important to select the right cameras that fit the unique needs of your situation. There are countless options and products features available.

Many packaged systems come with general purpose security cameras. Most vendors will allow you to replace the general purpose cameras with more advanced specialized cameras if you need them. For example, you may have a situation where three entrances into your building need to be monitored with just average quality cameras and you want to cover the parking lot with a camera that can read a license plate from 50 yards away. You can get 3 of the cameras that come with the system then replace the fourth with a camera that has high powered zoom capabilities.

By walking through this security camera selection guide you will be able to identify the special features that your situation requires and determine which cameras best fit your needs. Ultimately this will allow you to most efficiently spend your money while getting the best surveillance coverage.

1) Will you need color or black and white cameras? Most packaged systems come with color cameras which are better than black and white cameras at identifying valuable details of a suspect such as clothing or hair color. Typically black and white cameras are less expensive and perform better at low light than color cameras. Color cameras actually switch over to black and white in low light environments.

2) What type of night vision capability is needed? A typical packaged color security camera will have a night vision range of between 15 and 50 feet. High powered night vision cameras can have a range of 150 feet. The main factor of determining the night vision range is the number of infrared LED’s on the camera. Most general purpose security cameras come with 15 to 30 LED’s. Remember even color cameras record in black and white in low light situations.

3) What is the lowest acceptable image quality from each location where cameras are installed? You may have different image quality requirements from each location. One camera may be installed at the front door only to buzz people in when they arrive for appointments. Another camera may be used to capture license plates of cars driving through a large parking lot. These cameras have much different image quality requirements. Generally speaking the number of TV Lines (TVL) per inch is an indicator of the image quality that is produced by the camera. General purpose packaged security cameras commonly have 400 – 420 TVLs. Cameras that have 480 – 520 TVLs will give a much better image quality. Also, CCD cameras generally produce a better image than CMOS cameras.

4) Wired vs. wireless? Understand the disadvantages of using wireless security cameras before deciding to purchase them. A lot of people fail to realize wireless security cameras still need power via a power cable. Wireless cameras use wireless technology to transmit a signal to a receiver which is connected to a DVR or monitor, but most of them use a power cable to plug into a near by outlet. There are battery operated wireless security cameras, but the batteries need to be replaced quite often.

The image quality of wireless security cameras is often inadequate because of interference. The farther away a wireless camera is from the receiver and the more obstructions the signal must travel through the more the image quality is going to suffer. That being said, there are many, many applications where wireless security cameras are ideal. Many of the wired systems available have cabling that supplies both power and video (aka siamese cabling). This means all the power requirements can be managed from the same location as the DVR or monitor.

5) What elements are the security cameras going to be exposed to? Most general purpose security cameras that come in packaged systems can be used outdoors (as well as indoors) under normal conditions. If the cameras are going to be exposed to extreme conditions such as hail or very high winds or there is a high likelihood of vandalism you may want to upgrade to cameras with heavier and stronger housings and mounting brackets.

7 Questions to Ask Before Installing a Home Security Camera

7 Questions to Ask Before Installing a Home Security Camera

Home security cameras have become an interesting option to add onto a home security system. Business have for years used surveillance cameras to monitor the promotions. As the technology has evolved and prices have come down, they have become more feature rich and affordable. But, before you go out and purchase a set home security cameras there are a few questions that you need to ask yourself.

Do you want to hear as what you are seeing?

There are security cameras on the market that have a built in microphone. These cameras are really good as 'nanny cams' as you get to hear and see what is going on.

Do you want to store the images taken by the camera?

It really depends on what you are trying to accomplish with the security camera. If you want to know who is at the front door, do you really need to preserve the video images? No, not really. If you know someone has been using your hot tub while you're a work, then you need to have the images stored so that you can identify who it is.

When it comes to storing the video there are two basic options you have available to you tape or hard drive. Video tape recording systems are inexpensive and quite reliable. Storing digital video on a hard drive allows for easier editing and searching of the video, but video can consume a lot of disk space.

Wireless any one?

You now have the choice of installing a wired or wireless camera. The camera will still need to be plugged into an outlet for electricity; however, you do not have to pull a video cable for the camera to work. Wireless cameras are easier to interface with a home security computer system that will allow you to monitor and record the video.

Is the location bright enough for the camera?

There needs to be enough light for the camera to capture a clear image. If it is too dark or the sun is shining into the camera's lens, you will not get a good image. Every camera has a lux rating. The lower the lux value the better the camera can function in low light situations.

Will there be a way to get electricity to the cameras?

Some cameras plug into the wall and use electricity for power while others use a battery power. As a rule there is not an abundance of power outlet on the roofline outdoors.

Do you want to remotely view what your security cameras are recording?

When the security cameras a hooked up to a home security computer and that computer is connected to the Internet, it becomes possible that you can use a web browser connect to your home computer and view the video footage being recorded by your security cameras. There is some software that needs to be installed and configurations to your computer need to be made to support this.

How many cameras do you think you will need?

You will have to check with your monitoring system for your home security system. Some of the systems can only accommodate two or three cameras. You will need to match your system to the number of security cameras that you will be installing. It might not be a bad idea to plan ahead and buy a system that can accommodate more cameras that what you are planning on installing, room for future expansion.

There you have it. The top 7 questions you need to ask yourself before purchasing and installing a home security camera.

Be the Master of Your Digital Camera

Be the Master of Your Digital Camera

A very popular hobby that many people have enjoyed and many more people are learning to enjoy is photography. Taking photos with your digital camera can prove to be very enjoyable. Some will carry their camera with them wherever they go so they do not miss taking that special photo while others do it as a part time or weekend job to supplement their income. Whatever your reason may be for getting into digital photography, there are some things you need to keep in mind when taking your pictures.

Before anything else, you must realize that you are the director and you will absolutely determine how a picture will turn out. Do not be shy in taking photos of people or climbing a little hill to get that perfect shot of the ocean beyond the trees. Let your creativity shine forth, and you will learn to appreciate your photos even more. Taking pictures with a preconceived notification of how pictures are provided to be taken is the wrong approach to take. With that in mind, however, there are some things that you do need to be aware of so your pictures will turn out right in the first place.

One thing that some beginner photographers have trouble with is working with the flash on the camera. The flash can be your best friend or your worst enemy. You need to learn how your camera uses the flash with each setting or scene mode that it has. The camera will use the flash differently when the scene mode is set at a nighttime setting as opposed to its automatic setting. Use natural lighting whenever possible, but make sure that the sun is lighting the object or person you want to take a picture of the proper way. Taking the picture with the sun directly behind or in front of your subject will cause your photo to become either underexposed or overexposed. When taking pictures at night, do not get too close to your subject unless you want it to turn out very, very bright.

Practice makes perfect, and one way to get that practice is to take many photos of the same object but at different angles, distances, and with or without the flash. If you want, you can keep notes of what the lighting conditions are, whether you used the flash or not, the camera scene mode you used, if any, and your distance from the object. That should give you a better understanding of what you should expect you to encounter a picture-taking moment with the same conditions in the future.

Keep in mind also that you will need to devote some time to get better at your photographic skills. With time, you will develop a sense for taking a picture and having it come out the way that you want it to.

Opposing Arguments to the Use of CCTV Security Camera Surveillance

Opposing Arguments to the Use of CCTV Security Camera Surveillance

As the use of CCTV cameras increases across the United States and globe, so does the debt over their numbers and motives. There are many arguments for video surveillance, including peace of mind, loss prevention, crime deterrence and crime solving, but what about the other side of the story? Thousand of individuals and groups oppose video surveillance, and many of them have extremely valid points. What are the consequences of allowing "Big Brother" access to our entire public life? Will that ever lead to the invasion of our private going-ons? When does it begin to be too much? The ACLU has an entranet Web site, You Are Being Watched, devoted to the "high costs of camera surveillance systems, both in terms of money and civil liberties," and that is just one example of a group that is taking action.

So, what are some of the main arguments against the use of CCTV surveillance systems? Lets see …

Invasion of Privacy – This is the most common argument against surveillance systems. No one likes the idea of ​​being watched, but still we are starting to see security cameras on many more street corners and light poles. Cities normally justify these additions by saying they are monitoring and preventing crime, which is valid, but many people, both innocent and not, would rather the cameras not be there. While video surveillance is more commonly accepted in public areas, this sentiment comes into play more so with the use of covert and hidden cameras in private areas. Laws enforce restrictions in this arena, for now, but the main concern is the future of citizen privacy.

Mistrust – The use of security cameras in your home or business can make its occupants feel mistrusted. If your family members or employees are under constant surveillance, there is likely to be hostility and animosity in the air. Feeling like every move you make is monitored and recorded is not only creepy, but downright scary. Even the most trusted employees can become paranoid and nervous when a camera is pointing at their cubicle all day. No more dozing off, checking facebook, text messaging or doodling, you are being watched!

Not Proven Effective – Studies done in California and London have found that security cameras had little to no effect on reducing the crime rate. With an increase in the sheer number of cameras in many large cities, many replacing human security guards, this is a strong argument that will be the main target of many opposing groups. I think we can all agree that there is no replacement for a thinking, acting, problem solving human police officer or security guard, and if we begin to rely on cameras as pure deterrents, how do we plan on stopping crimes as they are happening?

Misuse and Abuse – The footage captured by CCTV cameras becomes intolerable to abuse and misuse by those who have access to it. For instance, the footage can be used to discriminate against people and for voyeurism. In the age of the Internet, this is another huge deal, as can be seen by all of the "hilarious" YouTube videos out there. I doubted the subjects would find most of them as funny. This obviously leads into the invasion of privacy issue, and is one of the primary concerns of activists. All it takes is one "funny guy" security guard to post footage or still images of an individual doing something embarrassing or that they should not be and reputations are ruined, privacy is obliterated and those that oppose CCTV will have more ammo.

All of these reasons are valid arguments against CCTV surveillance. There are many cities and countries that have massive surveillance systems, and we will likely see a large increase in public monitoring in the near future, so the more the public knows about the industry and their rights, etc, the more everyone can prepare for when It happens in your little corner of the globe.

Do you have any additional arguments against the use of security camera systems? What are your thoughts? Will you fight them or open your "public" life up willingly to being observed? Feel free to leave a comment with your thoughts and opinions.
