Choosing CCTV Cameras

If you are considering purchasing a security camera system, the choice of CCTV cameras is an important one. They are the basis of your system, and need to match what you intend the system to be able to do. There are a number of factors involved in choosing CCTV cameras. One of the first factors to consider is the location of the camera. If the camera is to be mounted outdoors in an exposed location, then you need a weatherproof model. Also, if you live in an area subject to extreme temperatures (less than -10 degrees F or more than 110 degrees F for color cameras, -10 degrees F to +122 degrees F for black and white cameras), then you will need a camera with a built in fan and/or heater. The fan and/or heater will broaden the temperature range that the camera can operate in. Cameras mounted indoors in a temperature-controlled environment do not require any special temperature considerations.

Another factor to consider when choosing a CCTV camera is whether to use a wired or a wireless model. Wired cameras will produce better images overall, with less interference from outside sources. Wired cameras are also cheaper than wireless models, but they will cost more to install because of the video cable that has to be run. Wireless cameras cost a bit more to begin with, but cost much less to install -- you don't have the expense of the video cable or the labor involved in running it. A wireless camera that operates on the 2.4GHz frequency band can transmit its signal, even through walls, doors and ceilings, a few hundred feet. If you require the cameras to be located further away than this, they will need to be wired cameras.

Another factor to consider is whether to use color or black and white CCTV cameras. Color cameras provide more details about what is recorded, but black and white cameras actually have a higher resolution. What this means is that, while a color camera can tell you the color of a car in a parking lot, a black and white camera might allow you to read the license plate on the car. So you need to consider your typical subject when you choose between color and black and white. In addition, a black and white camera can usually take pictures in less available light than a color camera.

Resolution is another factor to consider when choosing CCTV cameras. Resolution is usually specified as the number of horizontal lines in the image. A typical standard resolution for a color camera is 320 lines, while 380 lines is typical for a black and white camera. For high resolution cameras, a typical color camera resolution would be 460 lines, and for black and white it would be 560 lines. The higher the resolution, the more detail will be shown in the image.

These are just a few of the factors you need to consider when choosing CCTV cameras. For more detailed information on CCTV cameras and where to buy, visit the Total Security Warehouse website.

Buy your own spy equipment

Not too long ago, most spy equipment was only available to government, big business and other high budget organizations. It was simply too expensive for the average person. But thanks to advances in technology, many devices similar to the ones James Bond gets to use have come within reach of the average person. This article will discuss a few of these items.

One of the first things that comes to mind when thinking about spy equipment is a camera contained in a briefcase. Now you can purchase a complete surveillance system, including cameras, a DVR (Digital Video Recorder) and a display, all concealed in an every day briefcase. You can also get a complete surveillance system that's concealed in a backpack or a purse. And the price is much more reasonable than you might think.

Another piece of spy equipment that can be purchased at a reasonable price is a hidden camera, or spy cam. This is a small electronic camera designed to be hidden in a wall or a bookshelf. These are available at very reasonable prices nowadays. In addition, you can buy cameras that are disguised as working, everyday objects, such as a working cordless phone, a fully functional CD boombox, or a desktop pencil sharpener. These devices are wireless and are designed to "hide in plain site". The person you are keeping an eye on will never suspect they are being watched. They are easy to use, since there are no wires to run and they operate on batteries. You simply place them in the area you want to keep an eye on, then plug the wireless receiver into a VCR or DVR to record the images.

Another piece of spy equipment that comes to mind is a digital voice recorder. These devices are small enough to hide in a shirt or pants pocket or a purse, and sensitive enough to pick up any conversation in the room. They are in effect a self-contained "bug", like the ones you see the police and government using on TV. You can also get a microphone disguised as a necktie or a baseball cap. These digital voice recorders are easy to use -- you can use them to play back the recording or you can transfer the voice files to your PC or to a CD.

One final piece of spy equipment that is relatively inexpensive nowadays is a bug detector. These devices allow you to conduct a "sweep" of a room to see if there are any hidden transmitting devices such as a wireless camera or voice transmitter. If you suspect someone is watching you or listening in on your conversations, one of these devices can tell you for sure.

As you can probably see, there is quite a bit of spy equipment that is available to the average person these days. If you have need of it, you can find out more about these devices at the Total Security Warehouse website.

A surveillance system is more reasonably priced than ever before

A surveillance system for your home or business is cheaper now that it has been at any point in the past. This is in large part due to advances in technology. And they're easier and cheaper to install now, too, thanks to wireless technology. There are a number of components to consider when purchasing a surveillance system.

The first thing to consider is whether to buy a wired or a wireless system. Wired systems cost less and have less problems with interference, but cost more to install. This is mainly due to the cost of the wire and labor to install it. Wireless systems cost more, but you can save money on installation. If you plan on installing the system yourself, you may want to go for the cost savings of a wired system. But if you don't want all the manual labor involved in running wires, the added cost of wireless might well be worth the price.

The type of cameras you buy is the next thing you need to consider. You'll need to purchase weather-resistant cameras for locations outdoors, and decide where they will be mounted. You also have the option of purchasing hidden wireless cameras, mainly designed for indoor use, if you don't want to advertise the fact that you have a surveillance system. Exposed cameras are not a bad thing, however, as police statistics show that when burglars and vandals see a surveillance system, they go somewhere else to do their dirty work.

After deciding on the cameras, you'll need a display device. You can use a spare video input on a TV if you just have a few cameras (you can purchase a quad multiplexer that will allow you to use up to four cameras with one video input). Or you can purchase a dedicated video monitor. In addition, you can buy a kit that turns your PC into a DVR and a display device.

The next thing you will need to consider is some type of recording device to keep a record of activity. You can use a VCR, but you have the hassle of rewinding and fast forwarding to find a spot on the tape, plus the hassle of tapes wearing out. A DVR (Digital Video Recorder) is preferred nowadays, and they are not as costly as they once were. With a DVR, there's no fast forwarding or rewinding -- you can instantly jump to any spot in the video. Plus there are no tapes to wear out. You can buy a standalone DVR or one that's PC-based. In addition, as mentioned previously, you can use an existing PC as a DVR with the necessary kit.

Now that you know a little more about what you need for a surveillance system, you need to select a dealer to buy from. Be sure you select one who has experience in the surveillance and CCTV markets, and ask them to recommend the system that would be best for you.

Hidden Security Cameras Have Many Uses

Maybe you need to know what your employees are up to when you're away from your business. Or what your kids are doing when you're not at home. Or you might like to know how your child's caretaker treats your child when you're away. You might suspect that your spouse is cheating on you. Or that some illegal activity is going on near your home or business. Hidden security cameras can provide answers to these types of questions.

You can buy hidden security cameras these days that are disguised as working, everyday objects. For example, you can get a working cordless phone, a functioning kitchen can opener, a wall clock, a teddy bear, a working smoke detector or a fully-functional CD boombox -- all with undetectable cameras hidden in them. They look and act like everyday objects, so the people you are watching will never suspect a thing. And they're relatively inexpensive, too, thanks to advances in technology.

These hidden security cameras use small "board" cameras with a pinhole lens -- this is the key to hiding them in everyday objects. They can "see" through a very small opening, which can be disguised as part of the object. And since they're wireless and battery operated, there's no wires to give away the fact that they're actually cameras. They're also easy to install because there are no wires to run to the camera. You simply place the camera in the area you want to keep an eye on, and plug the output of the receiver into the display or recording device you plan to use to display or record the images. This can be a TV with a spare video input, a specialized display monitor, a VCR or a DVR (Digital Video Recorder).

These wireless hidden security cameras operate on a 2.4GHz frequency, which means they can transmit their signal through walls, ceilings and doors. Cordless phones and some wireless computer networking gear operate on this same frequency, so be sure you choose devices that are capable of selecting a free channel within the 2.4GHz frequency band. This will help to minimize any possible interference.

If you need to keep a record of the images, you can use a VCR or DVR. VCRs have limited storage per tape, and you have to deal with tapes wearing out, so a DVR is preferable. Prices have come down on dedicated DVRs considerably, too. As a matter of fact, you can even by a kit that contains all of the necessary hardware and software to turn you existing PC into a sophisticated DVR and display device.

No matter what your need might be for hidden security cameras, now you know a little bit more about them. Be sure and shop for equipment such as this at a company that has experience in the video surveillance and security business. Ask them for suggestions on the cameras that would be right for your particular purpose. For more information on hidden security cameras, visit the Total Security Warehouse website.

Increase the security of your home or business with wireless security cameras

Installing wireless security cameras in and around your home or business can greatly increase security. Wireless security cameras are fairly easy to install, and thanks to advances in technology, prices have never been more reasonable. This article will briefly discuss what to look for when purchasing wireless security cameras and what you will need in order to use them effectively.

Wireless security cameras consist of a camera/transmitter combination and a receiver. Look for a transmitter that uses the 2.4GHz wireless frequency for maximum signal strength and minimum interference with other devices. Cordless phones and some wireless computer networking gear use this same frequency, so you may have to experiment with the channel number that the wireless security cameras use within the 2.4GHz band. To minimize interference with other wireless devices, look for a camera/transmitter combination where this channel is either selectable or the transmitter automatically selects a free channel.

Some wireless cameras are battery operated, while others will need power run to them. Most that require power typically require a 12VDC source. The receiver for the wireless camera is mounted near the display or recording device used to view or record the images from the camera. The receiver uses a short wired connection to connect to a spare video input on the display/recording device. Look for a wireless cameras that come with free receivers for maximum cost savings.

You will need a display to view the images from the cameras, and/or some type of recorder to keep a record of the images. This is useful in helping the police to find the perpetrator if you have a break-in or are vandalized. You can use a TV with a spare video input to view the images, or get a special display monitor. Some wireless cameras come with a USB receiver that allows you to view the images on the monitor of your personal computer and record the images to your hard drive. You can also purchase DVRs (Digital Video Recorders) which are standalone devices or computer-based. Or you can buy a kit that turns your existing PC into a sophisticated DVR and display device.

DVRs usually feature a built-in quad, which is a device that allows you to view the images from up to 4 cameras on the screen at the same time. In addition, these devices can be used to cycle the view from more than 4 cameras. This cycles through all the cameras and shows the images from each group of 4 for a short time, then starts the process over again. This allows you to keep an eye on a much larger area with just one display device. These quads can be purchased separately if you do not use a DVR in your system, but just use it to view the images in real time.
You can also purchase a bundled system that includes the wireless security cameras, the receivers and a PC-based DVR. Usually you can save money on a system such as this over the cost of buying all of the items separately.

Now that you know a little about what to look for, this might be a good time to start shopping for wireless security cameras to increase the security in and around your home or business.

Security cameras can greatly enhance the security of your home or business

Security cameras can be used to greatly enhance the security of your home or business. Placing them in and around your location is a deterrent itself, as statistics show -- when burglars or vandals see security cameras they find somewhere else to do their dirty work. And they can help the police locate the people responsible if you do suffer a break-in or vandalism.

Security cameras cost much less than they use to, and they are relatively easy to install. Advances in wireless technology mean that you don't have to run costly video cables, and DVRs for recording the images are more reasonably priced than ever before. Look for a complete package that contains the cameras, the wireless receivers, a DVR and a display -- you'll save money over the purchase price of the separate items.

A wireless spy camera has a number of uses

You can use a wireless spy camera for a number of purposes. It can be used as a general security device, used to keep an eye on your employees while you're away from your business, or used to keep an eye on your child's caretaker when you're not there. And they're easy to use to - since they're wireless there's no video cables to run and most are battery operated.

You just plug the output of the wireless receiver into a VCR or DVR to begin recording images. Images can be played back on a standard TV using a spare video input. Advances in technology have really brought the price down on these devices as well. For more information about the wireless spy camera.
