Weatherproof Bullet Security Camera

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.


Deck Security Systems

Monday, September 27th, 2010

If you own a boat or a yacht then a deck security system is a small investment that can yield large returns in the area of security and surveillance. In addition, a deck security system offers you the peace of mind of knowing that your craft or vessel is safe and sound.

There are many types of digital video security systems that are suitable for use on your boat’s deck. If your boat is docked at a slip that provides electrical power, or your yacht has its own on-board generator, then there is an even greater selection of security systems available for use.

Let’s consider these deck security systems as two different categories. One type requires external electrical power supply either in the form of typical house current or as DC (Direct Current) supplied by the boat’s battery and the other contains its own self-sustainable on-board power supply. We’ll discuss the latter type first.

There are many different types of digital video security camera systems that can function by using rechargeable batteries. These systems are usually an “all-in-one” type system where the camera and Digital Video Recorder are all one unit. These deck security systems are usually suited for smaller craft, where one camera can satisfactorily cover the target area for security surveillance. In addition to creating digital video files these cameras often are capable of taking digital still photographs as well.

These systems usually contain an infrared (called a PIR) sensor. The sensor acts as a switch to turn the camera on and off when movement is detected. This motion detection switching conserves the power supply so that only a small amount of electricity is needed to maintain the unit when there is no activity.

In addition, the Digital Video Recorder or DVR is normally some sort of flash drive that saves the digital video or still photographs to removable flash media such as a Smartcard, Flash drive, etc. Since the DVR uses flash media, these units have the advantage of being able to remove the storage media and view any recorded data on another device, such as a personal computer for example. The disadvantage with these units is that the flash drives have relatively small storage capacities (for example 2 to 8 Gigabytes) so recording time is limited compared to a typical DVR unit that may have hundreds of Gigabytes of storage. Nonetheless these units are still powerful security devices that can provide high quality images of any one trespassing or tampering with your boat.

Another type of deck security system that is similar to this system uses the boat’s DC current for power. These systems should also be motion activated to conserve energy usage. These units normally run off of 12 volts of DC current so they may possibly be powered by your boat’s battery or by an extra battery carried on board the boat dedicated specifically to the security system. These deck security systems may employ the Flash drive type DVR or may even contain a mini-hard disk drive DVR to record images.

Finally, for slips that provide external electrical power or for ships that contain their own on-board 110 volt AC (Alternating Current) power, standard digital video security systems can be used as deck security systems. These security surveillance system cameras can be mounted either on the deck of the boat or on supportive surfaces of the dock/gangway.

There are several different types of systems that may be used in these cases depending on the resources available, location of the dock, etc. For example, wireless digital video cameras can be used that transmit their video data to a corresponding receiver inside the home or marina. If the home or marina has broadband internet access, these systems can be easily networked using the internet so that the owner can monitor the boat area anywhere in the world there is internet access. This includes using 3G or 4G cellular smart phones to view the target area.

Depending on the equipment used, these deck security systems may be able to store up to four weeks or more of continuous video monitoring. These systems can also include audio recording, motion detection, and many other features as well.

Regardless of the deck security system you choose, make sure the camera(s) are designed for outdoor use so they are protected from the elements, especially water. Cameras used for this purpose should have an Ingress Protection (IP) rating of at least IP65.
