How to Connect HD-CVI Cameras to an HD-CVI DVR

Written By:
Wednesday, March 19th, 2014

HD-CVI is a brand new CCTV technology that delivers High Definition Video over Standard Coax Cable. In this article, I will explain various options on how to connect your HD-CVI Cameras to your HD-CVI DVR. All of the products I will show are available at

The first option is the one we recommend the most.

HDCVI Wiring Option 1

As you can see in Option 1 this configuration utilizes Siamese Cable with a Distribution Box. The great thing about HDCVI (High Definition Composite Video Interface) as stated above is that you can achieve up to 720p resolution over Analog Coax Cable. To power the HDCVI cameras in this configuration you will need a distribution box. The one in this picture is a 4-channel distribution box. The 18-2 wire coming from the Siamese Cable connects into the distribution box and the other side connects into the female power lead, which then plugs into the power port of the camera. To see and record the video, you will connect the RG59 part of the Siamese Cable to the HDCVI Digital Video recorder (DVR) via a BNC Connector into the video input jack. The other side of the cable will connect to the BNC port on the camera via another BNC Connector.

In the next option, you will see the same sort of configuration except with a power plug instead of a distribution box.

HDCVI Wiring Option 2

In this option, you will use a 1amp minimum power supply to run power to one camera. If you have multiple cameras, either you can use separate power supplies or you can use 4-channel Output Switching Supply if you are powering up to 4 cameras, or an 8-Channel Power Supply for powering up to 8 cameras. In this configuration above for power, you will need a male power lead to connect to the power supply, attach the 18-2 wire from the Siamese cable, and attach the other end of the 18-2 into a female power lead. Then, just plug the power lead into the power port on the HDCVI camera. Keep in mind you will do this for each camera, even if using a 4-channel power supply. For video, the connections are the same as in option 1.

The next option is the simplest option but not highly recommended (although it does work and is good for novices).

HDCVI Wiring Option 3

In this option, we use a Plug and Play Power/Video Cable. There is no special wiring involved. For power, just plug the power supply into the power adapter of the plug and play cable, and then plug the other side of the cable into the power port of the HDCVI Camera. For Video, connect the BNC from the cable into the Video Input on the HDCVI Digital Video Recorder, and attach the other end to the BNC port of the camera.

In the next configuration the diagram consists of the same setup as above except with a distribution box as the power supply.

HD-CVI Wiring Option 4

In this configuration showing how to connect an HDCVI Camera to an HDCVI DVR, power is generated through a power distribution box. To send power to the camera using a plug and play video/power cable as shown above from the distribution box, you will need a female power lead. Connect the two wires of the female power lead to the port in the distribution box and connect the other end of the female power lead into the power port of the plug and play cable. Then, attach the other end of the plug and play cable to the HDCVI Camera. For video, plug the BNC from the cable into the HD-CVI Digital Video recorder and the other end into the camera.

In the next option, we move on to using Cat5e/Cat6 Ethernet cable for video and power transmission.

HDCVI Wiring Option 5

The great thing about High Definition Composite Video Interface (HD-CVI) is that video can be streamed through either Standard Coax Cable or Ethernet Cable. In the above diagram, the power starts with a plug-in power supply. In order to go from the power port on the power supply to the Ethernet cable, you will need to use a passive video and power balun. The power supply plugs into the power port of the balun and then the Ethernet Cable plugs into the RJ45 Jack of the Balun. Then the other side of the Ethernet cable is plugged into the RJ45 jack of the camera side Balun, and the camera’s power port connects to that balun. For video, The BNC from the Balun connected to the power supply is connected to the HDCVI Digital Video recorder and since the Ethernet cable is already plugged into the baluns, you just need to connect the camera’s BNC port to the other Balun.

In the last option in this article, we use the same configuration except with a distribution box.

HD-CVI Wiring Option 6

In this configuration, things get a little tricky. Instead of just plugging in the Ethernet cable using RJ45 Jacks, you will be working with the raw wires that are inside the Ethernet cable. You will use two of the wires for power and two wires for video. Whichever two wires you use, you have to make sure you use the same two wires on both ends.

For the power, connect the first pair of wires to the distribution box. On the camera side, connect those same two wires to a female power lead, and then attach the power lead to the power port on the HDCVI camera. For video, use another pair of wires from the Ethernet cable and attach both ends to passive video baluns. Connect one Balun to the HDCVI DVR and the other to the BNC port on the camera.

In conclusion, there are many different options to connect the HDCVI DVR to an HDCVI Camera. We highly recommend the first two options for best picture resolution and clarity. Plug and play cables are easy, but the clarity isn’t as good as standard coax cable. For more information on HDCVI, visit our “What is HD-CVI” page on our website at


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.


Web Based Wireless Camera Home Security

Wednesday, October 13th, 2010

Perhaps one of the most recent technological innovations in the area of digital video security is web based wireless camera home security. In the following article we’ll talk about what it is and how it works and hopefully provide you with enough information so you can decide if it is right for you.

Simply put, web based wireless camera home security is the use of wireless digital video cameras and the internet to provide security and surveillance for your home. A web based wireless camera home security system may be self- installed or installed by a professional. Likewise, the system can be personally monitored by you or by a 24 hour, 7 days-a-week professional monitoring service.

For the sake of information, we’ll separate web based wireless camera home security into two categories based on how the video signal is sent to the internet. One method involves the digital video camera sending its video transmission data via radio signals to a corresponding receiver, server, or DVR and the second method involves the digital video camera directly communicating with the internet. Each method accomplishes the same goal, allowing the home security cameras to be monitored, and in some cases controlled, via the internet.

Wireless digital video cameras can become web based wireless camera home security systems when they send their video transmissions via radio signals to receivers, servers, or DVRs which contain the technology to act as web servers and send digital information via the internet. These cameras normally use the 900 MHz or 2.4/5.8 GHz band technologies to transmit their video data. Incidentally, these radio band technologies are the same type used for land based wireless telephones.

These cameras contain a built-in transmitter and antenna with which they send the video data. This data can be sent to a corresponding receiver which is connected via a video transmission cable to the DVR. The DVR processes the signal and sends it via built in web server technology over the internet.

This method is not restricted to using a DVR. In fact the receiver can contain the web server technology and be connected to the internet for monitoring purposes and if so desired, a personal computer or DVR can be remotely located anywhere in the world there is broadband internet access to record the digital video files. The key here in this method is that the cameras transmit to another device that prepares the video data for transmission over the internet.

The alternative web based wireless camera home security method is to use wireless digital video cameras that can connect directly to the internet via a wireless modem or router. These cameras normally contain their own web server processing technology so they can package their video transmission data in a form that is compatible for internet use. These cameras usually send their signals via IEEE 802.11 format or WiFi to a corresponding wireless device such as a home router or wireless broadband modem which in turn is connected to a broad band internet connection. The cameras (as well as the DVRs mentioned in the first method) are usually referred to as wireless IP or internet protocol ready.

Regardless of which method is used to transmit the digital video cameras’ signal over the internet, a GUI or graphical user interface must be used to view and sometimes control the digital video cameras. For IP ready cameras, servers, or DVRS the GUI may be any typical web browser such as Windows Internet Explorer. On the other hand, depending on the manufacturer, the GUI may be a proprietary software program that must be installed on the device used to access the cameras’ data.

Web based wireless camera home security can be incredibly versatile in that the user can be notified via email based on a variety of “triggers” or home security cameras can even be monitored using 3G or 4G smartphones. Also, depending on the manufacturer and type, the cameras can even be controlled remotely over the internet. For example, a Pan-Tilt-Zoom (PTZ) camera can be controlled remotely from thousands of miles away to move or zoom in on objects.

Regardless of which method you choose, web based wireless camera home security is easy to install and economically priced for just about any budget.

Batteries for Home Security Systems

Thursday, September 2nd, 2010

There are many different types of batteries for home security systems. The following articles describes some basic battery facts and will help you to choose the right batteries for your home security system.

A typical “wired” security system consists of cameras, a Digital Video Recorder or DVR, and a monitor.

The DVR and monitor normally operate off of normal house current and have standard Alternating Current (AC) cords and plugs. Standard digital video cameras however, operate on Direct Current (DC) and normally operate off a power distribution box, a plug-in transformer/adapter, and or batteries. The plug-in transformer plugs into a common household outlet and transforms the AC power into DC electricity and a reduced voltage (usually around 12 volts DC or less as compared to 115 volts AC) and a reduced amperage (ranging from 400 to 2400 milliamps (mA) or more DC as compared to 5 to 30 amps AC). A power line carrying the lower voltage DC power is run from the power distribution center (or plug-in transformer) to each camera.

Some cameras, usually wireless types, allow the use of batteries for home security systems instead of power distribution centers or plug-in transformers. This eliminates the need to run a power line to the camera. If the camera is a wireless camera, this features makes the camera a truly wireless camera as there are no external wire connections needed for the camera.

Batteries for home security systems come in a range of sizes and types. Some cameras utilize typical battery sizes such as AA, AAA, C, or D cells while others require the use of a “battery pack.” A battery pack is usually a certain number of rechargeable batteries that are connected to each other and are held together by a plastic heat-shrink wrap. Before you stock up on a great internet bulk sale of batteries, there are a few things that you need to know to make sure you purchase the right batteries so you do not destroy your cameras.

First, your camera is rated to be powered by a certain number of Volts (V). The voltage of electricity can be thought of as the pressure of the electricity. Just like the pressure of water in a pipe determines how fast the water travels through the pipe, the voltage of electricity determines how fast the electrons travel through the camera’s electronic circuit. DO NOT attempt to use batteries that result in a different total voltage than what the camera specifies. When purchasing replacement batteries whether they are one-time use or rechargeable, the total voltage must be identical to that specified by the camera. (For example, if the original battery pack that came with the camera is 12 volts you must use a replacement battery pack that is 12 volts).

The second rating for the batteries for home security systems is the Ampere or Amp Hour (Ah). The rating for camera batteries is usually very small so instead of Amp Hours it is more common to see milliampere hours or (mAh). The milliamp hour is one thousandth of an Ah. Where voltage is the pressure of electricity, the mAh is basically the strength or capacity of the battery. Normally, the greater the mAh rating of the battery, the longer it will provide electricity per charge.

You should NOT use batteries with lower mAh ratings than specified by the camera manufacturer. You can use batteries with the same voltage but greater mAh to increase the run time of the camera between charges.

Finally, if your camera uses a battery pack, be certain that you purchase the proper battery pack connector. These connectors vary between battery pack types and manufacturer so it is important to make sure that you have the right size and type connector that will match your camera.

Using batteries for home security systems has it’s advantages and disadvantages. The biggest benefit of battery operated cameras is that there is no need to run any cable or wire to the camera which greatly reduces the installation time and cost. In addition, cameras may be mounted in strategic areas that offer the greatest possible surveillance that may not otherwise be possible if the camera required a power supply wire or transformer.

The biggest disadvantage of using batteries for home security systems is that there is a limited run time before the battery “runs out” of current. There is also an added expense of purchasing replacement batteries as even rechargeable batteries do not last forever.


Wireless Home Security Cameras and Monitors

Wednesday, August 18th, 2010

Providing your own home security in the form of digital video camera systems is becoming one of the most popular methods of residential security and monitoring. In addition, wireless home security cameras and monitors are become increasingly popular as well because of their versatility in application, ease of installation and operation, and reasonable pricing that makes them affordable for almost any budget.

What is the difference between “wired” and wireless home security cameras and monitors? Basically, “wired” digital video home security cameras use some sort of cable, usually an RG-59 coaxial cable to transmit their video signals to the monitors and/or Digital Video Recorders or DVRs. This cable is similar to the same cable used by most cable television companies. Although professional installers normally mount the cameras and run the cables using the least obvious arrangements, some homeowners may find the cables a bit too obtrusive, especially if they install the cameras themselves and use a different method.

Visibility of the cable isn’t the only reason for using wireless home security cameras and monitors. Sometimes it may be necessary to mount digital video security cameras in locations that may be difficult to provide cable to or in areas that are so far apart that it is easier to use a wireless system instead. For example, many complete home camera systems are used in rural homes that may contain lots of acreage and additional detached buildings such as garages, shops, or barns. If these buildings are located a significant distance from the home, cabling may seem impractical so a wire home security digital video camera is used instead.

One specific application of wireless security cameras and monitors is when they are used as baby monitors. Wireless digital video cameras can provide you with the peace of mind of monitoring your baby 24/7 and make great baby monitors. The digital video camera that is used for this purpose is usually a wireless night vision infrared camera and monitor system.

Infrared cameras used as wireless home security cameras and monitors, especially as baby monitors, are extremely popular and useful. The camera contains one of two special electronic sensor chips, known as a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS. These chips are sensitive to infrared radiation in the near infrared spectrum. This infrared radiation or “light” can be seen by the sensor chip (and therefore the camera) but cannot be seen by human eyes. That’s why infrared digital video cameras make great baby cams!

Infrared wireless home security cameras normally have an array of infrared Light Emitting Diodes or LEDs that surround the camera lens or are located somewhere near the camera lens and are pointed in the same direction. These LEDs bathe the target area with infrared light (in this case a baby crib for example) but this light does not disturb the baby because the baby cannot see it.

Often times these baby monitor systems are wireless home security cameras and monitors. The signal is sent using by the camera using radio waves to the monitor. Since the monitor is not connected by any type of cable it can be conveniently moved from room to room to maintain surveillance of the baby.

Remember, wireless home security cameras and monitors are not restricted to use as baby monitors only. These cameras and monitors are great for many different types of applications where a wireless camera and monitor would by useful.

Wireless home security cameras can be purchased with almost any feature or additional option that is available for their “wired” counterparts. Some of these features include: cameras for outdoor use or indoor use; cameras that can record audio as well as video; cameras that have Pan-Tilt-Zoom or PTZ functions to increase their field of view; day/night vision cameras; several different camera types or shapes such as box, bullet, and dome cameras; and even cameras that can be networked using the internet (called Internet Protocol ready or IP ready cameras).
