Bus Surveillance Cameras

Bus Surveillance CamerasIf you are a school bus driver and you have bus surveillance cameras, you know what a blessing they truly are.  Equipment that is visible (whether it’s actually working or off) has an incredibly large deterrence factor.  This doesn’t apply to just school buses but all kinds of buses and public transportation.

What is different on bus surveillance cameras than on regular surveillance cameras?  First, the whole system is a bit different.  Here is why.

A typical digital video surveillance system consists of one or more cameras, a Digital Video Recorder or DVR, and a monitor.  The cameras capture the video images, process them and send them to the DVR where they are processed further and saved on the DVRs Hard Disk Drive (HDD).  The HDD on a typical surveillance system is the same type of disk drive that is found on a personal computer.  It can hold terabytes of information but doesn’t do well when under the forces of vibration.

Bus surveillance camera systems are a little different.  First and foremost is the DVR.  The vibrations for normal travel of the bus are libel to make the hard disk skip and not record the video images properly.  Now there are many different types of bus surveillance systems and accordingly corresponding DVRs.  However the one thing that bus surveillance camera systems have in common is that most of these systems use non-moving parts.

They are able to endure very harsh environments making them well suited for
high risk vehicle applications like school buses, law enforcement, EMS,
transit, taxi, service or delivery vehicles that require rugged solid state
dependability for video evidence.

Creating a system with non moving parts is important because of the vibrations that are created by the bus.  The bus surveillance camera system must be able to work properly in spite of that factor.  SO how do they do it?  Most bust surveillance camera systems use a “no moving parts” SD recorder system.  All of the footage is saved on the SD card and when it’s full you just pull that card and insert another one or re-write over the one that’s already in the DVR.

These SD cards can be removed and inserted into a computer to view or store any of the media that is on the card.  The technology for creating these cards is constantly improving yielding greater and greater storage capacities.  Today, they can easily place a 2 hour trip on one card.

Bus surveillance cameras come in many configurations as well.  Some units are made with the camera, DVR, and monitor all in on piece.  Other units allow for the DVR to be mounted somewhere on the bus while up to four different cameras can be used for more comprehensive coverage.  Some of these multi camera systems are able to record all four cameras at once in D1 resolution.  Furthermore these multi bus surveillance camera systems, because of the larger separate DVRs can have record times of 60 to 200 hours!

Another benefit of bus surveillance cameras is that not only can they record unsafe or dangerous activities of the passengers but they can also record unsafe or reckless driving activities of the bus driver offering dual protection.  The following is a list of just some of the passenger activities that have been documented already on buses (school, public transportation, etc.):

  • Civil or criminal violations of the law
  • Drug use, sale, or distribution
  • Gang related activities
  • Vandalism such as cutting the seats, graffiti on bus surfaces
  • Sexual acts with or without consent
  • Throwing objects out the windows
  • Assaults, abuse or other harassment against the bus driver
  • Alcohol abuse or smoking while inside the bus
  • Standing or walking in the bus while the bus itself is in motion.

As we mentioned earlier, bus surveillance cameras provide dual coverage because they can provide documentation of the activities of the passengers as well as the driver.  Here’s a short list of driver related activities that have been documented:

  • Running red lights or stop signs
  • Failure to stop at railroad intersections
  • Bus driver, while driving, is drinking, eating, sending text messages, or using their cell phone for casual conversation
  • In vehicle driver passenger interaction, arguments, or abuse
  • Accident can be documented with the video used in court as evidence

2.4 Ghz Wireless Hidden Camera

Written By:
Monday, October 3rd, 2011

Sometimes cameras need to be placed in areas where wiring would obviously give away the fact that the camera is hidden.  When this is the case a 2.4 Ghz wireless hidden camera is the perfect solution for the job.

Unless a camera has its own “on-board” Digital Video Recorder or DVR, it will need a video transmission cable, commonly RG59.  However a 2.4 Ghz wireless hidden camera can eliminate the need for cables by sending the video transmission signal via radio waves.

It sends the radio waves using an on-board transmitter and antenna that use the 2.4 Ghz technology.  This is the same technology that is often used by many land-line based wireless telephones.

The 2.4 Ghz technology offers powerful and clear transmissions and is an excellent choice for wireless technology for digital video cameras.  However, this type of wireless communication is also known as Line Of Sight or LOS technology.  LOS refers to the method by which it transmits and receives and the fact that impeding objects can affect the transmission be reducing the maximum range of the camera.

LOS means that the maximum transmission range of the signal is as stated as long as the camera antenna and receiver antenna have a direct, unimpeded distance between them.  Also, the physical makeup of the object(s) will also contribute to determining how much the range may be reduced.  Trees, walls, glass, buildings, and other objects that are between the camera and the receiver all have an effect of reducing the manufacturers’ stated LOS range.

It’s important to understand this concept because if you know that the distance between where you want to mount your camera and where your receiver is, is 500 feet and your camera is rated for 500 feet but there are objects like trees and a couple of walls between the two, it is likely that the range will be reduced and the receiver may not be able to receive the signal.   If this is the case, it may be beneficial to try using a camera with a 1,000 foot range instead.

Security Camera King has many different types of 2.4 Ghz wireless hidden cameras available for purchase.  Some are designed to work with a DVR and others may just be designed to transmit to a monitor (a baby monitor is a good example of this).  The following list is a partial list of some of the 2.4 Ghz wireless cameras we have available for purchase:

  • Product# HC-BTNCM-G — Black and white hi resolution button camera*
  • Product# HC-SCREW-G — Black and white screw camera
  • Product# HC-BBMNT-GC — Toy dog baby monitor

  • Product# HC-WALLC1-G — Black and white wall clock
  • Product# HC-EXITS-G — Black and white Exit sign
  • Product# HC-DSKSP-G — Desktop speakers
  • Product# HC-VNTMR-G — Vanity mirror with Touch Activation
  • Product# HC-CBNDT-G — Carbon Monoxide Detector
  • Product# HC-WNDTN-G — Black and white wind tunnel camera
  • Product# HC-ALARC-G — Black and white Alarm clock camera
  • Product# HC-CORPH-G — Cordless House phone camera
  • Product# HC-BMBOX-G — Black and white CD/Boombox camera
  • Product# HC-ANMCK-G — Black and white suspended animation clock camera
  • Product# HC-CBNDT-GC — Carbon monoxide detector
  • Product# HC-ELCBX-G — Electrical utility box camera
  • Product# HC-ARWCK-G — Air Wick Air Freshener Camera
  • Product# HC-TISSU-G — Black and white tissue box camera

*Most of the cameras above that are listed as “Black and White” are also available in a “Color” version as well.

As you can see, a 2.4 Ghz wireless hidden camera can be disguised in many ways.  The above list is only a partial list; we have even more cameras to offer than this.

One last word of caution.  Each state has different laws governing the use of cameras and especially audio recorders without the subject’s knowledge.  Make sure you confirm you state’s laws before attempting to record anyone covertly.  This doesn’t mean that you can’t record improper or criminal activity but the planned, deliberate, covert recording may require special concessions on the part of the person recording.

CCTV Home System

Written By:
Friday, September 16th, 2011

If you are looking for peace of mind as far as the security of your home is concerned, try a Closed Circuit TeleVision or CCTV home system.  Today’s systems are so versatile that there is hardly an application that can’t be covered by digital video security.  And, there are many different types of systems for just about every application and budget.

Because electronic and especially personal computer technology has advanced so quickly CCTV home systems have become so versatile that it’s actually hard to find an application that they can’t cover.

First, the term “CCTV” is a carryover from the earlier analog systems.   A CCTV home system was so designated because the entire system was connected by cable in a closed circuit.  This was contrary to a typical studio analog system where the camera recorded the image and past it along to a control room where it was manipulated and amplified and sent out to a fairly large and tall antenna.  Under this system, anyone with a TV could become part of the system (by tuning their TV to the right channel).

A closed circuit television system by comparison was designed to be seen by only those who were directly hard wired into the system, hence the term “Closed Circuit.”  Today, the term is used a little more loosely, but the general meaning still applies.  Even though there are cameras that are wireless and therefore transmit their signals via an on-board antenna, the radio signal is usually a vary specific frequency that designated receivers or DVRs possess to receive the information.  In other words, a CCTV camera security system is still meant for only those people to receive that are within the defined circle of users.

CCTV home systems are rapidly becoming the system of choice for monitoring and protection for residential applications.  One of the reasons for this is because the system is digital.   Since the system is digital, it is able to share a lot of the same equipment and programming as a typical personal computer. This has great beneficial implications for a CCTV camera security system.  For example as hard disk drive technology increases creating storage capacities well into the Terabyte (TB) range, the video security camera system can take advantage of this large storage because video files are stored on such a mechanism.  Greater storage capacity yields a longer turn around time before the DVR re-writes older video files with new ones.

Today’s CCTV home systems are basically component systems which provide even more flexibility.  Generally, cameras and other peripherals to the Digital Video Recorder can be mixed and matched to the users’ utmost benefit.  For example, a typical 8 channel system may have 2 vandal proof dome cameras, an indoor box camera, 3 outdoor dome cameras that also have infrared “vision,” a door monitor camera with two way audio, and a Pan-Tilt-Zoom or PTZ camera covering the driveway and street entrance.

Security Camera King offers a tremendous variety of components to create your own tailor-made system.  Basically, these systems are based on the DVR’s that coordinate them.  Therefore, Security Camera King has 4 of their own proprietary DVRs so we’ll take a quick look at the four.

Elite Mini Economy
This DVR carries the same basic features as the other DVRs with a few exceptions.  It only has VGA and BNC connectors (no HDMI).  A PTZ control interface is also absent on this entry level DVR.  This DVR can record CIF quality on all channels at once, with D1 quality on channel one, all at 30 fps.

Elite Mini HD
This system has everything the Elite Mini Economy has except it does have an HDMI interface and can display high definition at 1080 p.

Elite Series
The Elite series has a multitude of features.  It offers everything the Elite Mini’s offer and more.  For example, in addition to camera hooks up that Elite DVR can accept alarm input channels and alarm output channels.  It can produce a display in High Definition (1080p) but also has video loop output options as well as video matrix output.  This DVR also contains a DVD-RW burner for making backups of digital video files held in storage on the hard drive.  PTZ control is also available on this model.

Ultimate Series

The ultimate Series has everything that the Elite has to offer with the significant difference being in recording power.  The Ultimate Series DVR package includes 520 TVL cameras and can record 704-480 at 30 fps on all channels simultaneously.

CCTV Alarm System

Written By:
Thursday, September 15th, 2011

A Closed Circuit TeleVision or CCTV alarm system for the home provides the user with the best of both worlds.  Video monitoring and recording for documentation purposes and alarm notification that something is wrong.

There are basically three ways of achieving success with a CCTV alarm system.  First most upper end Digital Video Recorders or DVRs have connections for contact points on alarm system.  They also have output connections for lights or sirens, etc.

Another way of using a CCTV alarm system is to set your camera system up so that it alerts you under designated conditions.  All of our DVRs have the ability to send the user an e-mail as an alert notifications provided the DVR has access to broadband Internet service.

The third way to use your system as a CCTV alarm system is to hire professional, 24/7 monitoring security guards such as Digital Security Guard.  The on duty guard can notify you, the police, the fire department, etc. if something appears to jeopardize the security and safety of you or your home.

Let’s take a closer look at each of the three methods to understand how they work.

First, using the DVR as the command center for an alarm system helps reduce the expense and confusion that could be created by owning a completed digital video camera system and an electric alarm.  To keep things straight, Security Camera King has connections for inputting contact points and outputting alarm out notifications to objects such as lights, sounds, etc.  This can eliminate the alarm base module and provide a way to place all of your security wires in one spot.

Secondly, all of Security Camera Kings DVRs have the ability to send the user an e-mail when a certain video condition occurs.  This is basically like a silent alarm.  This is a particularly useful feature for monitoring cars and people in “No Trespassing” areas.

Finally, one of the best ways to make your digital video system a CCTV alarm system is to hire a remote security guard to watch from one to all your cameras 24/7.  Our sister company, DigitalSecurityGuard.com does just that.  From our secure facility, we can monitor an unlimited number of your surveillance cameras simultaneously and ensure the security and safety of your home.We use nationally licensed and highly trained guards to monitor your digital video system and contact you, the authorities or anyone you designate, should they see an event occurring.

Security Camera King features several complete CCTV alarm system packages.  These packages are categorized by the number of channels the system can handle.  In addition to the number of cameras, these systems can also be categorized by DVR type.  There are 4 such DVRs available in our complete system packages.  They are the Elite Mini Economy, the Elite Mini HD, the Elite Series, and the Ultimate Series.

Besides number of channels and DVR type, security Camera King also offers these feature systems with two basic cabling options.  The first includes plug N play cables and the second is a bulk cable option.

The plug n play cable option includes a 100 foot long RG59/Power Cable complete with BNC connectors and power plugs terminating each end of the cable.   Basically, with these systems all that is needed is to mount the cameras run the cable and plug each of the cable ends into the camera and DVR and you have an up and running CCTV alarm system.

The bulk cable option includes a power distribution box(es) 500 feet or more of Siamese rg59/18-2 and all the BNC and Power plugs necessary to connect the cameras to the DVR and power supply.  The BNC connectors are twist-on connectors so no additional equipment is needed for these systems.  The bulk cable option is especially useful for cable runs over 100 feet in length or very short cable runs as well.

If you have any questions regarding the purchase, use, or installation of a Security Camera King CCTV alarm system package, contact one of our security experts today via on-line “Live Chat” or by telephone at 866-573-8878 Monday through Friday from 9AM to 6 PM EST.

Mini CCTV Camera

Written By:
Thursday, September 15th, 2011

What is a mini CCTV camera?  Arbitrarily we can say that a mini CCTV (Closed Circuit TeleVision) camera is any camera that is smaller than the majority of CCTV cameras sold as “Standard” sized cameras.  But generally, when the term “mini CCTV camera” is used, reference is made to the small cameras normally used for covert recording.

Thanks to modern technology, anyone can own a mini CCTV camera.  Just a few years ago, these cameras were so expensive they were cost prohibitive for the individual to own, if they were even available at all.  Today, not only are they affordable but they come in a wide range of types, each designed to satisfy a specific purpose.

To understand how this is possible, let’s take a look at the technology behind a typical contemporary digital video camera.  Most of today’s video security systems consist of three basic components:  Camera(s); Digital Video Recorders or DVRs; and Monitors.

Here is how an average digital video security system works.  The camera captures the video image and sends it to the DVR where the data is saved as a digital video file.  Actually, this file can be viewed live on the monitor and/or saved on the DVR for later viewing or archiving.

The key behind the mini CCTV camera lies in how the camera captures the video images.  Digital video cameras use an integrated circuit sensor chip to transfer light energy into electrical energy.  There is usually one of two sensor chips used; either a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS.

These sensor chips come in a range of sizes with the larger sizes usually producing a larger higher quality video picture.  Most miniature wireless security cameras use a 1/4 or 1/3 inch CCD or CMOS chip, so the camera can be incredibly small.  Of course, another contributor to their small size is the incredibly small, integrated circuits that prepare the video data and send it via an on-board transmitter (wireless) or via a video transmission cable such as RG59.

These 1/4 or 1/3 inch sensor chips usually provide a minimum 380 TVL high resolution black and white or color picture.  That’s a pretty good size video for a camera with a lens the size of a pin head.  In addition, these miniature cameras also employ the use of wide angle lenses that provide an extended field of view for the camera through the small opening.

The mini CCTV camera unit itself can be incredibly small as well.  Since the camera is so small and light, it can be mounted almost anywhere.  Better yet, for more truly covert recording needs, the camera can be imbedded within another object without anyone ever detecting the camera’s presence.

These cameras make great security cameras because you can monitor your surroundings without anyone realizing a camera is present.  This can be very useful when you suspect you may have an unauthorized individual tampering with or stealing your possessions.

Security Camera King offers a huge variety of different types of miniature wireless security cameras.  Here’s just a partial list of some of the models that we offer:

The Button Cam – It takes the place of a shirt button and it even includes five extra buttons so they will match up.
The Screw Cam – This camera looks like an ordinary Phillips head type screw.
The Wall Clock Camera – It looks like a typical office-type wall clock however in addition to the functioning clock, a camera is packed inside.
Desktop Speaker Cam – Functioning desktop speakers with a miniature wireless security camera hidden inside.
Exit Sign Camera – Appears to be a normal indoor “Exit” sign.  No one would suspect a camera is mounted inside.
Stuffed Toy Dog Baby Cam – This camera comes with a handheld LCD monitor and also monitors audio as well as video.  Although it does not record video or audio, it helps you keep a watchful eye on your baby without disturbing him or her.
Vanity Mirror Camera – A double sided vanity mirror with a camera inside.

Most miniature wireless security cameras come with power supplies or battery packs and Security Camera King includes a free 2.4 GHz receiver with most mini CCTV cameras.
