Weatherproof Bullet Security Camera

Written By:
Monday, May 2nd, 2011

There are very few bullet cameras these days that can’t be called weatherproof bullet security cameras.  In fact, all of the bullet cameras that we offer for sale at Security Camera King are weatherproof.  That is one of the benefits of owning a bullet security camera.

A weatherproof bullet security camera bridges the gap between the typical box camera and the conventional dome camera.  Box cameras are great cameras and have been around for a long time.  However, to maintain the box camera’s versatility it doesn’t come with all the necessary parts.

That is, for example, a box camera is usually sold as the body of the camera with the lens sold separately.  This is done to increase versatility, as you can always change lenses if you change the location or want a different field of view for the weatherproof bullet security camera.  However, this added versatility doesn’t come without added cost.

In addition, most box cameras were designed to be used indoors, under protective cover from the weather and the elements.  If you want to use a box camera outdoors, you will need to purchase an additional accessory, an outdoor camera housing.  While neither the lens nor the housing are terribly expensive, they are nonetheless, an expense that you need to consider when comparing cameras.

The dome camera is also an excellent camera.  Originally designed primarily for indoor use, the dome camera has come a long way in a relatively short period of time, technologically speaking.  Like the other models, dome cameras have their own advantages and disadvantages as well.  One such disadvantage is that due to their small size, dome cameras cannot support as many InfraRed Light Emitting Diodes (IR LEDs).  This ultimately means their range in conditions with little or no light will not be very long.

The weatherproof bullet security camera bridges the gap between the box and dome cameras because it features some of the items that are considered the very disadvantage of the other types of cameras.  For example, most bullet cameras come with a factory inserted lens.  Usually these are of the fixed type but there are many weatherproof bullet security cameras that come with varifocal lenses and motorized irises as well (See Security Camera King’s Product# OB-LX550IR150L922).

When shopping for a weatherproof bullet security camera, you probably will at some point, begin comparing each camera’s specification sheet. One term that we would like to clarify is the IP code or IP rating.  You’ll see this rating in the specifications as something like “IP65.”

IP stands for ingress protection and is a standard written and maintained by the International Electrotechnical Commission or IEC.  Its purpose is to provide specific descriptions of a camera enclosure’s ability to protect the camera inside.  An Ingress Protection rating has two digits (like the example in the previous paragraph).  The first digit represents the degree of protection from solids while the second digit indicates the degree of protection from liquids.

The first digit of the IP rating can range from 0 to 6.  A rating of 0 means there is absolutely no protection against contact and ingress or objects.  As this digit increases in value up to 6, each rating indicates protection from progressively smaller objects.  A rating of 6 for the first digit means there is absolutely no ingress of dust and there is complete protection against contact.

The second digit of the IP rating can range from 0 to 8.  Again, a rating of 0 means there is absolutely no protection against liquids.  As this digit increases in value up to 8, each rating indicates protection from progressively more intense contact with water.  A rating of 8 for the second digit means the camera is protected from continuous immersion in water deeper than 1 meter.  There for a reasonably good IP rating for a security camera would be IP55 or IP65.

Last but not least is the IR range.  Not all, but a good majority of the weatherproof bullet security cameras are also capable of IR video imagery.  This is accomplished by using IR LEDs to “light up” the field of vision.  This IR “light” is invisible to the human eye.

Generally, the more LED’s the greater the range and area of coverage under IR conditions.  Weatherproof bullet security cameras have lots of room for IR LEDs and can obtain fairly long ranges.  Before you buy the camera, make sure you check the range you will require so as to by the appropriate camera.

Outdoor Motion Activated Security Surveillance System

Written By:
Thursday, November 4th, 2010

An outdoor motion activated security surveillance system is an excellent tool to provide security and surveillance for almost any residential or commercial application. Modern technological advancements have made this surveillance system incredibly versatile and reasonable priced as well.

An outdoor motion activated security surveillance system’s cameras are specifically designed for outdoor use. These cameras (as opposed to indoor cameras for example) are designed to be housed by a protective enclosure. The enclosure protects the camera from weather, dust, and other objects.

An outdoor security 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.

An outdoor motion activated 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 security camera system. Since the camera will only record video when motion is detected, this can save a tremendous amount of file space use on the system’s Digital Video Recorder or DVR.

Since the DVR records video images in sequence, it will continue recording until the DVR’s storage capacity is full. Once the DVR is full however, the video image files are rewritten over the files that are the oldest, continuing this process until the DVR is full and then repeating the process over and over again. A motion detector activated camera can extend DVR recording times before repeating and rewriting, significantly.

In addition, a motion activated security camera system camera must have a power supply. This may be in the form of a small, low-voltage Direct Current (DC) power line run from a power distribution center to each camera or from a nearby plug-in transformer. Many cameras have the ability to operate on the power supplied by batteries, either one time use types or rechargeable types.

The PIR sensor on a motion 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.

There are many additional/optional features that contribute to the versatility of an outdoor motion activated security camera system. Some of these features include:
• Pan-Tilt-Zoom (PTZ) functions
• Day/Night vision
• Night vision infrared recording
• Wireless cameras
• IP ready cameras and/or DVRs

These features coupled with the motion activated feature make the outdoor motion activated security camera system appropriate for almost any commercial or residential application.
