Best outdoor surveillance cameraThe best outdoor surveillance camera depends on your situation and your budget. Here are some tips to help you navigate your way to the best outdoor surveillance camera for your situation.

Tip #1 Coverage Area

The first step in buying the best outdoor surveillance camera is to do a survey of the area that you want to cover. Some states have very stringent laws about recording scenes on property that does not belong to you. Decide where you want to put the cameras. The outside of most properties will need more than one surveillance camera to cover the whole area.

Ask yourself if you were a criminal where you are most likely to go on your property. These are the areas that you want to make sure to cover. If you have outside storage on your property, then you will want to make sure to cover those areas. Most people want to make sure and cover the doors of their homes. In most circumstances more than one camera will be required.

Think about covering your whole area, but pay special attention to certain areas. The front door of your home may need a point, tilt and zoom camera so that you can see who is at the door from a remote location. The driveway may need a high resolution camera so that you can see the license plate of a car. The storage area may need a fixed camera that records who goes in and out of that area of your property.

Tip #2 Width of View

The next step in determining the best outdoor surveillance camera is to determine the width of the area that you need each camera to cover. Knowing this will help you determine exactly where you need to place the camera. Many people find it helpful to actually stake out the area with small stakes or use chalk lines to make sure each of the vital areas are covered. It is good idea to have the most important areas covered by more than one camera.
Security cameras come equipped with different lenses. Knowing how wide an area you need each camera to cover will assist you in buying the correct lens for each camera. It takes some experience to look at a picture that has a very wide width of view. The picture is smashed together and seeing details may be hard. In some areas a fisheye camera may be the right choice. This camera records its images right under the camera. These pictures record a full circle and can take real talent to observe the details.

Tip #3 Distance

By now you should have a pretty good idea of where you want to place the cameras. Take out your tape measure. Measure the distance from where you are thinking about placing each camera to the most vital place. This will help you further determine the type of lens you need each camera to have.

Security cameras come with four types of lenses. Some cameras come with lenses that are meant to record objects up close. Some cameras come with lenses that are meant to record objects that are far away. Some cameras come with lenses where the recording distance can be focused at the time of installation. Other cameras come with lenses where the distance can be controlled from a remote location.

Cameras can be brought that will record at different lengths. Most manufacturers like to expand the distance that their cameras will adequately record. Look for the top number and subtract 15 percent. If the camera says it will record at 100 meters, then expect the camera to record a great picture at up to 85 meters.

Tip #4 Style of Camera

Security cameras come in four basic styles. Choosing the right one will help you choose the best outdoor security camera for your situation.

The first type of security camera is the box camera. These cameras are the largest of the surveillance cameras. They are difficult to hide. There presence may be a great deterrent to thieves. Thieves may move on to a different place when seeing one. The box camera is great for outside use because the lenses can be changed easily depending on the unique circumstances. These cameras must be placed in a special housing when used outside.

The second type of security camera is the bullet camera. These cameras are shaped like a tube of lipstick. Most bullet cameras come with one type of lens. The advantage of a bullet camera is its small size. This allows the camera to be easily hidden. These cameras also have to be placed in special housing to be used outside. It is easy to tell where the bullet camera is pointed. Therefore, thieves often figure out how to operate where the camera is not pointed.

The third type of security camera is the dome camera. These cameras are circles. They generally record the action that happens under them. These cameras must be placed in a special housing to be used outdoors. It is difficult to tell exactly where the camera is pointed. Therefore, criminals have a hard time telling exactly what is being recorded. Dome cameras are often equipped with fisheye lenses. It is harder to interpret a picture taken with a fisheye lens.

The fourth type of security camera is the pan, tilt and zoom camera. These cameras can be controlled from a remote location. The camera can be tilted up and down to catch action that occurs above or below the cameras normal position. This can be useful to observe someone wanting to get into your home or a package left at your door. The camera can also be panned from left to right. This allows you to follow the action as it moves. The camera can also be zoomed to allow you to see details of a scene better.

Tip #5 Resolution

Resolution on an outdoor security camera is measured in two ways. The first way is called television lines. This is the number of lines available to record the action. For the best Best outdoor surveillance camera resolution you will need at least 540 television lines.
The second way is megapixels. Most of us are familiar with megapixels on digital cameras. These tiny points make up the picture. Today, outdoor security cameras with ten or more megapixels are very affordable. The higher the megapixels number, the more details you can see in the photo. This is especially important where you need to see the tiniest details.

While you may buy a high resolution camera, the camera’s resolution is only as good as the resolution of your whole system. If the recording device or the monitor will not support the resolution, you are wasting your money spent on resolution.
The best camera for outdoor use has a built-in memory card. This memory card allows the camera to store photos as well as sending it to the recorder. This will assure that you still capture the footage if something happens to the network.

Tip #6 Wired or Wireless Security Cameras

Outdoor security cameras come wired or unwired. Most people prefer the unwired versions for outdoor use. Just as the name implies, wired security cameras are hooked by wires from the camera to the recording device. When using wired outside many things can happen to the wire causing it to stop working. For example, the wind may blow down the wire or a tree limb may break the wire.

When using an unwired version remember to check that nothing will interfere with your signal. In the best of circumstances the signal will only travel so far. The length varies by the quality of the camera. The signal will not travel as well through walls. Other objects in the environment, such as cordless phones and microwaves can also interfere with the signal.

Tip #7Networking

Your camera depends on your network. You will need a recording device and a monitor to view the photos. As mentioned earlier, both will affect the resolution of your system. The recording device will have a built in memory. It is important to decide how often you want the recorder to dump the old pictures.
Compatibility can be an issue. Make sure all components of your system will work together.

Tip #8 Housing

Most outside security cameras must have some type of housing. It is important to buy the right housing. The conditions in your environment will determine the right type of housing. If you live in a wet environment, then the moisture can do damage to your system. If you live in a dusty environment, the dust can ruin your camera without correct housing. Extremely cold and extremely hot environments can hurt your security camera. Make sure that you consider all these factors when buying housing for your outside surveillance system.

Tip # 9 Lighting

It is important to consider the amount of available lighting when buying your security camera. Security cameras generally come in three types.

The first type of camera is meant to be used in daylight conditions. It will record beautiful pictures during the day. When the camera does not get enough light it will stop recording.
The second type of camera is the night vision camera. These cameras magnify the available light to record a picture when darkness sets in. They still rely on a certain amount of light being present. As the light gets less, the footage recorded is a green color.

The third type of camera is the infrared camera. These cameras produce their own infrared light. They can record a black and white photo when absolutely no light is available.


Home Security Motion Sensor

Monday, November 14th, 2011

One of the many home monitoring devices is the home security motion sensor.  There are several types of motion sensors and that even includes digital video camera systems.  In the following article we’ll take a look at a few home security motion sensors and see how they work.  Hopefully this will help you to decide what type of home security motion sensor you need.

A home security motion sensor system is an excellent tool to provide security and surveillance for almost any residential application.  Modern technological advancements have made this camera system incredibly versatile and reasonable priced as well.

A home security motion sensor system may be used indoors or outdoors (or both for a given system).  Outdoor sensors and cameras (as opposed to indoor sensors and cameras for example) are designed to be housed by a protective enclosure.  The enclosure protects the camera from weather, dust, and other objects.

A home security motion sensor camera may be rated according to the protection that is afforded to it by the enclosure or its casing.  This rating, an Electrotechnical International Commission (EIC) standard, is call an Ingress Protection rating, IP rating, or IP code.

The rating consists of the letters “IP” followed by two digits, for example IP65.  The first digit of the rating describes the extent the camera is protected from solid objects and the second digit indicates the extent the camera is protected from liquids.  The example IP65 rating means the camera is dust free and protected from water sprayed from nozzles in any direction.

The first digit of an IP rating for an outdoor motion activated security camera system ranges from 0 – 6 with 0 indicating that there is no protection against contact or ingress of objects.  As the number increases from 0 to 6, the rating indicates that the camera is protected from objects continually smaller in size.  A first digit IP rating of 6 indicates no dust and complete protection against contact.

The second digit of an IP rating for the camera ranges from 0 to 8 with 0 indicating that there is no protection from water.  As this digit increases in value the rating indicates progressive protection from water with 1 meaning protection from dripping water and 8 meaning continuous immersion in water.

A home security motion sensor security camera system also has a unique characteristic as indicated by its descriptive name.  The cameras only record video when motion is detected.

This is accomplished by an on-board Passive InfraRed (PIR) sensor.  The PIR sensor can detect the infrared radiation from objects in the camera’s field of view.  If the sensor detects a significant change in the infrared radiation in this view, it assumes it is created by a moving object; hence it detects “motion.”  The sensor is connected to a relay that turns the camera on in recording mode to capture the video images.  The camera shuts off or stops recording when the sensor detects that the motion has stopped or after a pre-programmed period of time.

This feature, though small and simple in design and appearance, can offer tremendous benefits in the functioning of a home security motion sensor system.  Since the camera will only record video when motion is detected, this can save a tremendous amount of file space used on the system’s Digital Video Recorder or DVR.

In addition, all of Security Camera King’s DVRs can be connected to the Internet, so if a camera detects motion, the DVR can be programmed to send you an email, alerting you of the fact as soon as it happens.

A less elaborate mechanism one could use is a PIR motion detector as the sole home security motion sensor.  This of course, would be wired (or transmitted by radio waves for wireless models) to an alarm system main panel which then could call specified telephone numbers.  When someone answers on the other end, a specific message, usually previously recorded by you, the owner plays.  However, this method though admittedly simpler and cheaper, will not be able to provide actual visual documentation of the perpetrators.

The PIR sensor on a home security motion sensor activated security camera uses a very small amount of power to stay on.  In fact, compared to the power required to capture video, the PIR sensor’s power usage is significantly lower.  Motion activated cameras that operate on battery power last significantly longer between charges or battery changing because the motion sensor, in effect, conserves battery power.

Do you need a home security camera? Security Camera King stocks a vast selection of home security cameras and home security camera systems at discount prices. If you’re unfamiliar with today’s digital video home security camera, read on for some information about the way they work, the different types, and some of their features.

The type of home security camera marketed today is the digital video camera. These cameras are light-weight, powerful electronic cameras that deliver the video image in a digital form. Older models of home security camera were heavy, bulky analog cameras that had less features than today’s camera.

A digital video home security camera works by transferring light energy into electrical energy. The electrical energy can be quantified or measured and used to construct a digital video image. Digital video is actually several digital photographs taken very rapidly (on average around 30 photographs per second) in succession. The rate at which the camera operates is often referred to as “fames per second” or fps.

A digital video home security camera captures a video image and sends it to a processor/DVR or Digital Video Recorder. This unit creates a digital video file that can be viewed instantly on a monitor or saved on the DVR for later use.

Digital video cameras use one of two different sensor chips to create the video image: A Charged coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS. These chips range from about ¼ inch to about 1 inch in size. Usually, a larger chip produces a higher resolution picture (and the cost of the camera is higher also.)

Depending on the camera type and your use, you may also need to purchase lenses for your camera. Lenses are sold based on focal length which is normally stated in millimeters. A long focal length is needed for a greater distance to the target. Check out our CCTV Lens Calculator in the CCTV Learning Center for more information.

There are three main types of home security camera based on shape. Box cameras are normally used indoors unless they are placed in a protective cover for outdoor use. Box cameras are fairly obvious so that may or may not be a benefit. Bullet cameras are normally weatherproofed for outdoor use, but they are also indoor/outdoor models. Bullet cameras can also be somewhat obtrusive. Dome cameras are one of the more popular home security camera types. They can be flush mounted with only the dome protruding from the wall or ceiling. These are probably the less conspicuous style of camera and one of the most popular.

Digital video home security cameras are connected to the DVR by an RG-59 coaxial cable or similar cable. Each camera must have this cable run from the camera location to the location of the DVR. In addition, a power supply wire must be run from a wall transformer or power distribution box to each camera.

If you need to mount your cameras where running these wires could be a problem, you may want to consider a wireless camera that can utilize rechargeable batteries. Wireless cameras with motion detectors can enhance your system even more by conserving on battery power.

Another type of home security camera that is very popular is the baby monitor camera. This camera is usually a night vision infrared camera and a monitor. The systems may or may not be wireless. Infrared cameras use infrared Light Emitting Diodes or LEDs to illuminate their target area. This light can be seen by the camera sensor but is invisible to the human eye so you can monitor your baby all night long without disturbing him or her.

There are several features or options that are available for home security cameras. Some cameras may come standard with these features while others are considered an additional option. Here is a partial list of some of these features:
• Audio recording
• Day/night vision camera
• IP or Internet Protocol ready (these can be networked using a simple broadband internet connection) cameras
• Pan-Tilt-Zoom or PTZ cameras
• Hidden or disguised cameras (cameras are built into common, everyday objects to disguise them for covert monitoring – great for use as nanny cams)

• If you need outdoor monitoring, be certain to purchase “Outdoor” or “Indoor/Outdoor” type cameras. (Indoor only cameras are not adequate for use outside.)
• Plan cabling routes in advance. Each camera will need an RG-59 or similar coaxial video transmission cable run from it to the DVR. Be certain you have enough cable plus an extra 10-25% to do the job.
• Each camera will also need a power supply. This is normally provided by using a plug-in transformer with a line run from it to the camera or from a line run from a central power distribution box.
• Consider the camera type needed for each location and the type of camera mount and location in advance.
• If video cabling makes you uneasy or you find it obtrusive, consider purchasing wireless cameras.
• Determine if any of your camera locations will require special lighting condition cameras such as day/night vision or night vision infrared cameras.
• Determine if there are any other special features needed for your cameras (such as Pan-Tilt-Zoom (PTZ), audio recording, disguised or hidden cameras, etc.)
• Determine the storage capacity size needed for your DVR. The best way to do this is to ask one of our security experts and they can tell you, based on your situation, how much storage space you will need or you can visit our CCTV Learning Center – Calculators to estimate.
• Determine if you need a broadband internet connection and how you will provide that connection to your DVR system.
