The Advantages of a “Tribrid” Digital / Network Video Recorder

Written By:
Thursday, April 23rd, 2015

The field of security camera and video recording technology is changing every day. Advances are constantly being made. Sometimes change can happen so fast that there’s a need to merge different technologies into a single device, especially when there’s a need to support older technologies because it still may be in heavy use.

In the security tech world, this is where the Tribrids come in.


The basic concept behind “Tribrid” DVRs aren’t a exactly new. Far from it. Previous to the release of Tribrid DVRs, there were Hybrid DVRs. Hybrids are capable of streaming and recording both standard analog and IP Network cameras. The Tribrid simply introduces the ability to now have HD-CVI cameras (itself a bridging of technologies) in addition to those analog and IP cameras.

So lets take a quick look at each of these camera styles.

Analog Cameras

Analog camera technology goes back a long way. A very long way. Decades in fact.

Most modern analog cameras max out about 960H resolution, which, though better than older analog cameras, still doesn’t allow for much image detail.

Older Analog CCTV security cameras capture an analog video signal and transfer that signal over Siamese (coax) cable to the DVR, the recorder then converts the signal from analog to digital, compresses it, and stores it on a hard drive.

Currently, the only real advantage analog cameras offer is that they can be acquired fairly cheaply.

And because they’ve been so common for so many years, odds are most businesses have a few lying around, or even still have them currently in use. And while they can offer a baseline level of security, they’re quickly being replaced with their newer, smaller, sharper, higher resolution descendants.



HD-CVI is a brand new bit of technology which stands for High Definition Composite Video Interface. It combines the best of both analog and high definition (HD) technologies. Until very recently, standard analog CCTV video maxed out at 960h resolution. The only way to get higher resolution would require completely swapping out the old system, including wiring, and switching to an HD compatible format.

Using a video transmitter / receiver, HD-CVI can transmit up to 1080p resolution uncompressed video and audio over a single ordinary standard CCTV coaxial cable (instead of needing separate cables for video and audio) over larger distances than HD-SDI or Network IP, without the latency and lag issues that can notoriously plague those formats.

One of the biggest advantages HDCVI tech brings to the table is it allows anyone that has previously installed analog cabling to leave their cable and power in place and upgrade to High Definition which saves on having to re-wire.. an incredibly practical and resourceful bit of innovation.

Network IP Cameras

network ip

One of the most important changes in the security camera field in recent years has come from the incorporation of ONVIF standard. So just what the heck is ONVIF? ONVIF is an acronym for Open Network Video Interface Forum, which is industry forum for developing a universal global standard interfaces of IP based physical security products. In short, it means that no matter which camera, digital video, or network manufacturer you buy from, if they’re ONVIF compatible, they’ll all be cross compatible.

Network IP cameras are sort of distant cousins to their older analog relatives, as they do actually capture an analog image. But, that image is then, almost instantly, converted to a digital signal inside the camera, and then that digital stream is sent through the “Local Area Network”, or LAN, through your Ethernet cable. The power supplied to the camera over the same cable is through Power-Over-Ethernet (POE).

So essentially, Network IP cameras can be accessed easily over the internet via your NVR. They can even be aimed (in the case of Pan Tilt Zoom, or PTZ cameras) or adjusted via an software app from your cell phone or tablet device, making these cameras some of the most versatile and configurable on the market. In addition, they are able to transmit BluRay DVD quality video (1080p), and in with some cameras, even higher than that.

Keeping it simple

For all complicated technology that goes into a Tribrid, they couldn’t be easier to use. Actually, it’s almost exactly the same as using a traditional DVR or NVR, they typically use the same type of graphical user interface, or GUI. The only difference being that you’ll simply be getting all the features and inputs that would normally be separated in other DVRs or NVRS merged into a single unit.



One of the most crucial elements of any security system is storage. If you don’t have enough storage space, you’ll constantly need to be rewriting your old footage, or lowering the quality of the image inside the settings of your DVR/NVR, which will no doubt cause you to miss crucial details in your footage.

Luckily, even the smaller model Compact Tribrids can hold up to 4 hard drives, each up to 6 terabytes each… so with the smaller version, you’ll have a total capacity of 24 terabytes. Full size Tribrids can hold up to 8 (!) hard drives.. that’s a whopping 48 Terabytes of video data. In simple terms.. if you connected eight HD cameras, you could record up to 98 (24 hour) days of hi def, 1080p video, at 30 frames per second. Or if you connected cameras to all sixteen channels, you could record up to 49 days of uninterrupted HD video.

Furthermore, if you decided to back down the footage to, say D1 resolution, you could get over 230 days of recording time at 30 frames per second.

To determine just how much storage you need, and how long you’ll be able to record, check out the hard drive storage calculator.

All In One

Tribrid DVR’s are basically the all in one, “one stop shop” that will essentially take on whatever syle of cameras you have at your disposal, and are especially useful for those that just don’t want to go thorough the hassle of replacing their wiring, or just don’t want to throw out their old security cameras. Whatever your video recording needs, the Tribrid can handle it.


Our Goofy Security Camera Videos Part 3: The Final Chapter, Finally

Written By:
Monday, February 23rd, 2015

Finally.. after months of absolutely no demand whatsoever, the third and final chapter… the “Return of the Jedi” if you will… (oh, wait.. that’s not the final chapter anymore).. ok, the “GODFATHER 3” of our goofy security camera videos trilogy has been compiled. Please withhold your applause til the end.

In the event you’ve been living under a rock, under a tree, on a deserted island… Here’s the premise: For every security camera we produce, we do a video test…. and put those on the inter-tubes for your viewing pleasure. Back in the day, we would occasionally do silly stuff while making these camera demos, primarily to amuse ourselves and hopefully make the videos entertaining AND informative. And while we don’t really do these sillier demo videos anymore, we had some fun making them at the time. Plus, they do in fact show off the video quality of the cameras… so we figured we might as well compile them, so that someday, someone, somewhere in the universe might get a chuckle out of them.

So this is it.. the last of the silly stuff. As usual, we’ve got our 2 trusting guinea pi.. uh, ‘actors’, Ian and Jose.

The Talent

…who have always been ready to put their expendable lives in jeopardy… to risk life, limb, and sanity just to demonstrate to the the world the difference between 1 megapixel HD-CVI box cameras and 3 megapixel IP bullet cameras. The responsibility that rests on these heroes’ shoulders would turn most to puddles of liquid Jell-o, but these hearty men soldier on, unafraid of how their immortalized buffoonery will besmirch their family names for generations to come. Anyway, on with the show…

1) Traffic Cone Beat-down

Day / Night IR Demo – CVIOB-EL1MPIR50-D2-E – 720p HD-CVI Indoor/Outdoor IR Bullet Square Economy Cam

Among those of us in the know… traffic cones have a reputation for being jerks.

bad cone

Always have. So it was no great surprise to us that when a jerky cone in our warehouse made a flippant remark in Ian’s general direction one day, he went absolutely ballistic and gave it a beat-down to end all cone-related beat-downs.

2) Ian Defies Gravity

Day / Night IR Demo – IPOB-EL3MPIR50-D2 – 3 Megapixel IP Network Square Bullet IR Security Camera

In this video, we see Ian displaying his defining talent… balancing gardening tools.

3) A Dance, A Flappy, and A Roll

Day / Night Demo – 2MP 12X Flush Mount IP Pan Tilt Zoom Security Camera – IPPTZ-EL2MPL12X-Mini-F

Name says it all, folks.

4) Chortle Kombat

Day / Night IR Demo – CVIOD-LX1MPIR100L2812-W – HD-CVI LX Series 1.3MP Varifocal IR Camera

Once every three hundred and fifty-three years (give or take).. a portal to a mystical, magical martial arts tournament opens up in our warehouse, and all manner of deadly ninja demons come to challenge us to random fights in the middle of our tech support sessions. Usually we just ignore them til they get bored and leave, but every once in a while they catch us at a bad time and we have to “take out the trash”. And that’s exactly what happens here.

5) Styrofoam Peanut Allergy
foam peanuts

Much like traffic cones… the bags of Styrofoam packing peanuts in our warehouse can occasionally get a bit of an attitude. Maybe it’s because their soft spongy innards will soon be used to ensure the safe travels of our DVR’s when we send them out into the world. But in this case, we suspect this particular bag had a bone to pick with Ian… a personal vendetta… judging by the sheer ferocity of the attack. The bag just thew itself upon Ian’s weak and helpless body from 20 feet up.

It was at this point that Ian’s savior Heath heard his girlish screams… and came sprinting to the rescue.

Heath, the tragic hero

Using his famed bare-handed hunting skills he typically reserves for bears and mountain lions, Heath bravely wrestled the bag off of Ian’s ravaged person, and then, tragically, despite his valiant selflessness was consumed by the non-biodegradable bag-creature while Ian limped away to bandage his wounded pride.

6) Ninja in Training

Day / Night IR Demo – IPOD-TP2MPIR50-W – 2 Megapixel TP Series IP IR Vandal Resistant Dome

After his near fatal battle with a sentient bag of Styrofoam packing peanuts, Ian decided it was high time he learn how to defend himself. So after he saved up about 150 bucks, he started regularly attending a ninjitsu school hidden in the back of an abandoned Sizzler restaurant, where he learned his stealthy skills from a ninja sensei cleverly disguised as a hobo. Sadly, after building his confidence though several victorious battles, he later lost his new-found ninja prowess due to amnesia he acquired in a tragic break-dancing mishap.

7) Argument

Day / Night IR Demo – IPOB-EL3MPIR50 – 3 Megapixel IP Network Bullet IR Security Camera

One day, someone took a big bite out of Ian’s p.b.& j. sandwich, then re-wrapped it in foil and put it back in the break room fridge. Ian, understandably took exception to this, as his wife had spend days making that sandwich. He suddenly became suspicious of everyone. He wanted answers, and he wanted them now.. or then, I guess. Ian thought the evidence could be found on the security camera footage, but sadly, someone, possibly the culprit, unplugged the 3 megapixel camera facing the refrigerator. So he took his frustration out on poor Jose.. who simply wanted to spend his lunch break drinking his quadruple-mocha-frappe-whip-latte in peace. The world was never quite the same after this.

8) Cone Drop

Auto Tracking Demo – IPPTZ-EL2MPIR250L30X-AT – 30X 2 MP Auto Tracker IR IP Network PTZ

Following the infamous P.B.&J. flame out, Jose developed a dark side. He wasn’t taking guff from anyone, least of all from another uppity traffic cone. Look at the pure confidence in which he just casually yet menacingly tosses that cone to one side… like a rapper dropping the mic after besting someone in an acapella rap battle. He just doesn’t give a darn, and he doesn’t care who knows it.

9) Creepy Stare

Day/Night Demo – CVIVD-LX1MPIR50L2812-W – HD-CVI LX Series 1.3MP Varifocal IR Vandal Dome

Witness the moment Jose’s new-found dark side finally took hold. Spooky, ain’t it? Whatever you do, don’t stare directly into his eyes while saying his name 3 times backwards. Nothing will happen, and you’ll have wasted your time completely.

Well, that’s all, folks. We’ll be back next month with a decidedly less amusing but probably more informative article. Thank you for your patience.



How to Prevent a Christmas Theft (as Well as All Year Round)

Written By:
Wednesday, December 24th, 2014


As you all know Christmas is already here and thieves are on the loose. In this day and age, electronics are what are being gifted and criminals are simply waiting for packages to be delivered to your homes. They are even bolder to go to your door and steal them. Some even break into your home while you are  hard at work and grab all the items under your tree. There is also a black market for electronics that are even set on an Order basis unfortunately. These thieves are more coordinated where they are following delivery trucks and have “look outs” once a package or multiple packages are delivered and steal them to gain a profit. How can you prevent theft at Christmas and all year round?

The video above shows how a criminal hits two houses at the same time, and sadly, even though they have a surveillance system, you cannot make out their faces. There are solutions to these issues.

There is a Startup company that will accept your packages and ship them to you at your convenience. The company is called DoorMan. Their services costs $4 per package or $20 a month. a small price to pay when you are not home. Although this is only at the moment available in California it could become a trend nationwide. There is also Amazon. They allow customers to use lockers in public spaces to pick up packages.

The Importance of Having a High Definition Security System

Below is a video showing the differences between resolutions so that you can understand the necessity of having a High definition system.

**Please make sure that the settings gear is set to 1080P

As you can see with a 1080p camera you can zoom in further and get the facial recognition that you are looking for. The 1080p camera in this video is an HD-CVI camera which is a newer technology that launched this year and is taking over the industry, as it is not as expensive than an IP based System. It delivers the same great High Definition signal as IP.

Integrating Alarm Outputs from Your Security Recorder

You can also integrate our DVR/NVR systems with other devices such as a garage door, which you can have the UPS, Fed EX or USPS guy drop your package inside of your home. You can utilize one of the security recorder’s relay-out to the signal on your garage door opener, which will allow you to open the garage door, monitor what he or she is doing, and closing once he or she has left the garage. You can also have a microphone and a speaker connected to an amplifier and have audio and give commands to the Delivery guy as to what to do.

You can use this diagram here to connect your recorders alarm output here.

The above illustration shows an ELK 912 which is a very popular relay. As you can see you can connect a siren as well if you wish but for our purposes you can see Figure 2 which illustrates how the relay will connect to the Garage Door system.

This works with your Mobile Application as well with TechProSS  (IOS & Android). You can see the channel where the camera in your garage is set, as well as engage the Alarm triggers within the application. Please make sure before making a purchase or getting these items to check to see if your recorder does have the alarm outputs.

Lets move on to the Microphone and Speaker attached to the Amplifier.

As the above video illustrates you will need an amplifier and a horn. There are a few different  amplifiers that you can pick up. Some have even a built-in speaker on them. The video is old but it gives you the idea of how this functions. Let move on to the items that you will need.

  • Mono Amplifier
  • Speaker Horn or normal Speaker if indoors
  • cables and connectors

Connect the Speakers or horn to the amplifier output. Then we need to connect the audio-out to the amplifier. Once this is done we have the Audio Output.

We can now move onto the Microphone side just in case you want to hear the person inside of your garage.

The video below will show a basic installation for a microphone using Plug and Play Cables.

Integrating Snapshot Alerts through an FTP Server

We can also further integrate this system to capture and send images base on a momentary switch such as a doorbell. This will send a snapshot to an FTP server.

*This feature can only be set up to transmit the snapshots based on a timed interval.*

This can also be used by adding a PIR that will interface with an alarm input in your recorder. This will allow it to receive the signal and take a snapshot of the person in front of the door or sides if you wish to use this. Many installers will also use PIRs [Passive Infrared Sensor] instead of having the recorder creating a motion from a camera. This allows you to pin point where you want the motion to be captured from, as well as having the ability to set the cameras to 24-hour mode as opposed to motion only.

If you are wondering what application or how to obtain a File Transfer Protocol server, it is as simple as installing software like Filezilla onto your computer.

You will need to open some ports in your computer’s firewall rules. Port 21 is what is used normally and this can be changed to better suit your needs as many other devices might be using this port.

Since we are using this internally we are not required to open the ports on our router.

Open your Windows Firewall and set your rules here. Set an exceptions.



Set your directory. This is where you will have your files stored, and finally  you will need to set it up with users who will be accessing files.

Within filezilla, click Edit->Users

Set your passwords and users along with their permissions.

If you want to go all the way, meaning having the ability to access your FTP server anywhere that you have access to the internet as well as an FTP Client, ensure that you have the manual or gather the information on how to properly open the ports on your router for the FTP server and input your computer’s IP address. Be sure to set your computer to Static IP. I am assuming you have  a Windows computer.


Navigate to your Control Panel, Network and Internet, Network Connection and select or highlight the correct adapter. In my case my computer is wired so I select the correct adapter and right click hit properties and IPV4. This opens a window where you can designate the IP address for the computer.

If you are unsure if the IP address is being used in your network by another device you can open up a command prompt  [ Windows Key + R] . This will open a window where you can input “cmd” for command prompt and click OK.

command prompt

Once you have the command prompt open you can input “arp -a” this will show all the IP addresses being used on your network.


This command will come back with all the IP addresses that are live or assigned in your network. It will also show if the IP is Dynamically assigned or statically assigned.

cmd arp

*** You can also used on of my favorite IP scanners. Angry IP Scanner ***


After reviewing this solution and gathering that you can protect your property as well as any packages coming in or out of your property, you can have the time to enjoy the Holidays without the worries of not having your property not protected.

Happy grinch


Introducing the 4 channel 1080p HD-CVI Mini DVR

Written By:
Friday, October 24th, 2014


When you hear the word DVR you automatically think of Digital Video Recorder. Well, what kind of DVR? Cable companies like Xfinity use DVR technology intergraded with cable hardware so you can view hundreds of channels and record up to 4 broadcasts at the same time (of course monthly DVR service fee applies).exfinity The security camera industry uses DVRs to record video and audio data to internal hard drives. It is safe to say that there are IP security cameras that can blow away the traditional analog security camera system, but it really takes a lot of configuration, networking equipment and sometimes big money. Now you have the new HD-CVI systems like the 4 channel 1080p HD-CVI Mini DVR. In this article I will go over the on-board accessories and what you can do with them using the proper configurations with both hardware and software. First I will talk about the inputs:

hd-cvi-2mp-1080p-indoor-outdoor-ir-bullet-camerahd-59881big The 4 channel 1080p HD-CVI Mini DVR has 4 HDCVI video inputs which accept 2 megapixel resolution HDCVI cameras like the CVIOB-EL2MPIR50 that is one of my favorites. These HDCVI cameras are motion detection 100% compatible giving you a great way to not only save hard drive space, but add more days to your recordings. This unit can do wonders when configured correctly; you are able to configure detailed settings in the OSD and at the HDCVI DVR.

Also, the max run on the video feed is a block busting 1600 FEET.


Motion Detect Example: You can install a 2MP HD-CVI Bullet Camera (CVIOB-EL2MPIR50) at a door entrance that requires a person on the other end needing access through that door. You can not only get that camera feed from the door when the motion is triggered, you can also give the authorized person access from anywhere on site or off site. The configuration is simple all you have to do is have the proper alarm inputs and outputs configured properly both hardware and software.

This unit also can hold (2) 7200 RPM 4TB internal hard drives for ultimate recording.


This 4 channel 1080p HD-CVI Mini DVR also provides 4 audio inputs for real time listening and recording. This feature is perfect if you want to set up 2-way audio communications in a warehouse or at a big company property or just wanting to listen and record audio for future evidence. The connection is simple first you will need powered microphones for the audio inputs and an amplified speaker for the audio output for the listening part, remember all audio can be configured for recording.

The RS-232 is the on board serial port (serial communication transmission of data) for old school configurations. Ordinary COM (Debug), keyboard connection and transparent serial port (COM input and output via network )image4

USB inputs are used by the control mouse to maneuver through the DVR’s menus.

The RS485 port is not needed to use to control our HD-CVI pan tilt zoom cameras like the 720P HD-CVI PTZ with 250 Ft IR. This camera is priceless having the ability to record 1.3 megapixel images while having the ability to zoom in on a perpetrator for real time action. A great benefit of the HD-CVI DVR is that there is no need to run extra wires when wanting to add a CVI PTZ because the transmission is all done through the coax RJ59 cable.hd-cvi-ptz-20x-1_3mp-720p-with-250-59599big

The RJ45 is a 10M/100M/1000M self-adaptable Ethernet port. This connection is what the HDCVI DVR uses to establish the link to the inside and outside world using a router. Without this technology we would not be able to communicate using our PC, MAC or mobile device whether it is an HD-CVI, analog or IP security system.

Alarm inputs is my main focus in this article. Using this feature in the HD-CVI Mini DVR combined with the alarm outputs can create a complete secured location. The alarm relay is 30VDC 2A,125VAC 1A (activation alarm).

Example: You can configure this unit’s alarm capabilities to alert you when sitting at an office environment so when a person walks through a first door or detected by a beam detector it can trigger a sound using a buzzer. This will direct your view to a monitor configured to bring up a camera in that area so you can then use the DVR’s interface or web service to let them in, or you can even use your compatible mobile device to see who is at the front door and give them access.

maglock diagramimage2IMG_6225

This set up would involve an analog door sensor or beam detector, a single 12V relay, a maglock or a normally closed door strike, 12V power supply, high grade alarm wire and a 4 channel 1080p HD-CVI Mini DVR. The configuration is simple: First you wire and configure the power supply to the relay and then you wire and configure the DVR alarm inputs and outputs to the (output) MAGLOCK and the (input) to the sensor. The next step is to set up in the GUI ( Graphic User Interface ) at the HDCVI DVR.

First, if using the unit’s interface you can click on the setup tab and then click on the event tab and go to the alarm page. There you will configure the alarms inputs and outputs. You start out by enabling the channels and setting the type, antidither, record channel, delay, alarm out, latch and tour remember to hit save after the configuration.



USB outputs that uses thumb drives for backing up settings and events.


Alarm outputs, like I mentioned previously in this article, give you ultimate access controls right at your finger tips. Imagine if you had control over door security when a burglary or an in-house crisis arises. You can really try to control the situation if you can restrict access to doors leading to potential victim’s right from your PC or a mobile device.


Video BNC output can be configured using the spot out matrix control. You can display desired video windows and tours with out seeing the configuration menus. The HDMI and VGA outputs will display the HDCVI’s full menu functions but you can still configure these monitors to display a tour.


The audio output is used to configure a speaker for listening purposes.

In conclusion the 4 channel 1080p HD-CVI Mini DVR can be used for many many configurations. It is a cost effective unit and at the same time performing at optimal peaks using the inputs and outputs of this new technology would put you ahead of the game.

You can read more about this HD-CVI DVR in the manual here.


Invention of the Security Camera and Recording System

Written By:
Monday, September 22nd, 2014


Everyone dreams about some kind of invention that they know will make a difference in the world. Back in 1933 a chicken keeper accomplished that. At first his invention was not taken serious but now we see him as the first amateur photographer that invented the security camera. His name was Mr. Norbury, from London England, and he had set up a security camera system using a small box camera wired through iron pipes and booby-trapped a door where he kept his chickens. When someone tried stealing his eggs he would trip a lever balanced by sand bags to pull the trigger, taking a snap shot picture of the thief. Mr. Norbury was successful in catching his plumber and using the picture as evidence. When the judge asked Mr. Norbury who took the picture, he said, “well your honor, the thief did.”


Security cameras have come a VERY long way since then and now we use them in our everyday lives from the government to the regular mother and father wanting to keep an eye on their house keeper or nanny. You can find cameras practically on every corner from traffic lights to schools and I personal love the aspect that my children can have some piece of mind when attending school. The operation, design, shape and color vary for these image capturing boxes. You can install dome, bullet, vandal proof and pan-tilt-zoom camera that have great features like auto tracking.

One of my favorite new security cameras is the Panoramic security camera it gives you a full human perspective when viewing the live video stream, the experience is like actually being there in person. This new type of technology uses multiple cameras, usually 4 high-resolution cameras side by side in one housing apparatus using all the cameras video inputs and converting them into one panoramic stream. Then the camera encodes and delivers to any viewing device providing a 200 degree view. This is great when wanting to capture a large area using only 1 camera install installation. These cameras have the capability to be viewed from anywhere in the world and on most mobile devices using the manufacture’s app.



Another one of my new favorites is the IPPTZ auto tracker. This security camera can pan left, right, up, down, zoom and focus at the control of the user. The feature that I love is the auto tracker, as it has the ability to track and follow a target when detected. When connected to the web service utility you can configure settings like zones, tripwire and alarms so when an object crosses the configured zone, alarms can go off and it will auto track that object until it’s out of view. Officials all around the world use this technology along with face recognition to track and capture known fugitives.

What about the recorder?


VHS (Video Home System) format for the VCR (Video Cassette Recorder) that a Japanese company invented in the 1970’s. JVC was in financial ruin but Takano and Shiraishi continued to work on the project in secrecy within the video division. By 1973, the two engineers successfully produced a functional prototype


In the past there was no way to record live CCTV footage, but then came the VCR  allowing multiple events to be recorded to an analog VHS tape. Time and space was very limited to these recording devices.


Now we have DVRs and NVRs (Digital Video and Network Video Recorders) capturing and writing video data to hard drives, increasing the time and space you can save. Now companies are inventing new integrated units like the hybrid and tribrid combining analog, IP, and CVI Technology.

Imagine, when you’re building your own custom computer or gaming system you start with the case, well it would be awesome if there was a company that sold custom-built DVR/NVR cases, motherboards, memory, hard drives, power supplies, BIG fans and all the cool accessories that can be added to give style and personality to these units. One of my pet peeves when building a custom computer is to always have proper cooling and ventilation, fast hard drives, powerful power supplies, video card, cables and so on… You never know what the future holds!!!



Cabling, cables and connectors have also come a long way. Transmission of data/signals over cable started with AT&T using copper wire strung along telephone poles. Telephone signals traveled down these lines as analog electrical waves to form voices and each call required 2 wires to form a complete circuit.

linesman phone

Broadband began when the demand for more television broadcast signals skyrocketed and now the coaxial is born being the first broadband medium. AT&T installed its first coaxial cable between New York and Philadelphia on 1936. One of the first security camera systems used coaxial for the transmission of video data to a monitor. Here at Security Camera King we have RG59 Siamese cable with high-grade copper shielding for high-speed transmission. Attached to the cable is a pair of power wires making installs a breeze with maximum video signal run length is about 750 feet. Microwave radio relay is coaxial and microwave radio relay working in tandem. It is a broadband system by which telephone and television travel via radio along a series of towers.

old tvimagesCAX8JSHT

Fiber optics systems, The New Cable on the block is a technology that uses rapid pulses of light traveling on fibers made of ultra pure glass. This digital medium is one of the best and fastest way of transmission by far, able to send data over miles of cabling with ultimately no interference.


Cat5/6 cabling has been around for a bit, connecting networks and computers together for businesses and residences. Now security camera systems can be configured using IP camera technology.


This type of configuration is ideal when wanting to have high-resolution megapixel quality to really catch the identity of a perpetrator. Category 5 and 6 cable max run is around 300 feet. When the network configuration is configured correctly these systems perform flawlessly. The ability to log into each camera’s interface and make detailed adjustments is priceless.

POE is another new feature I love about the Ethernet hookup. The Installer’s Dream, Power over Ethernet- one cable carrying both data and power to the IP cameras, no need to power the camera locally.


While on the subject of new technology try checking out HD-CVI, this configuration uses RG59 coaxial cables to transmit HD quality high-resolution feed to the HD-CVI DVR, recording awesome events to your hard drive for better recognition. The great thing about HD-CVI is that the max run length of the Video cable is 1600 feet, WOW!

In conclusion the evolution of security camera systems has come a long way; I sleep very comfortable knowing that my Security Camera King System is keeping an eye on my family, business and home.
