Tuesday, September 29th, 2015

Since there are a lot of Pan Tilt Zoom (PTZ) Cameras available, I will explain in this article on how to best choose the correct PTZ for your Security Camera Installation.

I will start by showing the different parts of a PTZ camera.

1. Parts of a PTZ camera

(a) Housing – Usually composed of an aluminum bell shaped cover (image 1) or some models have abs plastic housings (images 2,3)

(b) Camera module
This is where the image CCD sensor, optical lens, and the motors that control Zoom and Focus are located.

Camera Module

(c) PTZ control board
The PTZ control board processes RS485 data  that converts it into mechanical movements.

PTZ Control Board

Note: On this particular PTZ control board it has dip switches (the red block with white switches). This allows you to change the protocol and ID of the camera. Some of our cameras are configured via the OSD (On Screen Display) menu.

(d) PTZ motors – are the small motors that allow the camera to perform up, down, left and right functions. Marked by the arrows are two step motors; the one to the top controls up and down movements and the one at the bottom controls left and right movements (Image 1).

Note: The motors used on a PTZ camera are known as step motors which use steps (teeth) that allow a more precise movement vs. standard electromagnetic motors that require higher RPM’S and torque. Below are the two animated examples of an electromagnetic motor (image 2) and step motor (image 3).

(e) PTZ Pigtail – is the cable that comes out of the camera which allows you to connect power, video, network, audio and alarms.

The Standard size IPPTZ cameras have alarm, audio, analog BNC out and an RJ45 jack (image 1). Mini-IPPTZ do not have an analog out option.

Our analog PTZ cameras have rs485, ground, BNC analog out and DC power plug (image 2)

Note: RS485 is a simple protocol used for communication between two or more devices. The nature of RS-485 allows transmission of  PTZ data along side power or in electrically noisy environment without interference. It has been tested to work at 1600 ft. on CAT6e cable.

2. Technologies

Currently our PTZs  come in three different technologies

1. Analog

2. IP


(a) Camera cable run limitations and options to extend if necessary

Analog has a 1000 ft. Video and RS485 Range but can only be powered up to 150 ft. before voltage drop. Two ways you can counter the power limitation is by:

1. Having power at the camera
2. Using a power supply with a higher amperage rating. An example of that would be if your camera is rated at 500 ma and your run is over 150 ft – use a 2-5 amp power supply. Although theoretically it should work we do not recommend exceeding the 150 ft. limit

IP has a 300 ft. limit due to standard networking limitation. Since power, video and RS485 can be run on a single CAT6e cable there is no way to increase the range without additional equipment. In the event you have to exceed the 300 ft limit you can use a POE injector that allows you to extend an additional 300 ft.

HD-CVI has 1600 ft. video and RS485 limit.  You can use CAT6e for both the RS485 and Video; for the video you will need video baluns to allow 1600 ft. range. The power has the same limitation as the analog cameras and will required local power or a higher rated 12v 2-5 amps depending on the camera requirements.

(b) Video quality and Resolutions

Analog – Our analog  cameras come with 700 TVL

IP – Range from  1.3 Mega Pixel, 2 Mega Pixel, and 3 Mega Pixel

HD-CVI – Currently only supports 1 Mega Pixel (720P)

(c) What are  differences between IP, analog + HD-CVI

1. An analog camera has to be physically connected into the DVR to record video and has a limitation of 1000ft.

An IP camera does not have to connect directly to an NVR. Simply by configuring some the network you can access your camera anywhere in the world. Let’s say your camera is in California and your NVR ( Network Video Recorder) is in New York. You can actually record the video from that camera at your New York location. This type of setup is used frequently by government and cities to monitor remote cameras.

2. Both the IP and HD-CVI support HD resolution, 720P and 1080P, whereas the analog only supports D1 resolution at 700 TVL

Note: The higher the resolution of a camera, the larger the images. It allows for wider coverage areas and more details vs the analog resolution. Because the images are larger on higher resolutions its better suited to use the digital zoom to get a closer look at an object.

3. Mini and Standard size cameras

Two of the major differences between our mini and standard sized PTZ cameras is the size of the housing and the optical lens capacities. The mini cameras are more aesthetically appealing in smaller homes and offices. The larger housings are better suited for larger homes and commercial applications.


Standard Size PTZ

4. Camera modules

(a) The camera module houses what is called the CCD or CMOS board (image 1), lens and motors that allow fine adjustments of zoom + focus (image 2).

Image 1 – CCD OR CMOS board

Image 2 – PTZ lens with control motors

ccdboard ptz lens

(b) Image Sensor – captures light and converts it into a digital image that can be stored onto the DVR/NVR. Currently there are two different types of sensors, CCD and CMOS. There isn’t much difference as far as image quality, but the CMOS sensors are known to handle brighter than normal scenarios extremely well. The CCD sensors were designed for IR applications where cut filters and automatic shutters are used. But in the past few years with advancement in technology, cameras now offer WDR (Wide Dynamic Range) and IR cut filters (Infrared Cut filters) which allows digital and mechanical adjustment for your specific setup. So it doesn’t matter if your using a CMOS or CCD as your end results are of high quality.

CCD cmos

(c) Optical lens – Allows for adjustment of zoom or focus. When you zoom in, the lens moves closer to the image senor so the image becomes larger. When you zoom out the lens moves away from the image sensor which make the image small and results in a wider view.  When referring to 12x zoom on lets say our PTZ-LX700L12X mini it means it can zoom in 12 times the normal amount. Generally you can find out what the range on the lens is by multiplying the lens size by the times zoom. So in our PTZ-LX-700L12X you can multiply 5×12=60. Five being the lens size multiplied by zoom gives you maximum mm size of 60 mm. In this case this camera has a varifocal range of 5-60mm

Here is an example of our 23x PTZ camera. The approximate distance from the camera to the truck is 380ft.

6. Mounting options

PTZ cameras are designed to rotate a full 360 degree there for an arm mount (image 2), pendulum mount (image 3) or ceiling mount bracket (image 1) is used for mounting the cameras.

Ceiling mounts- A ceiling mounting is great for any application that requires a PTZ camera but with a low profile. The better half of the camera goes into any surface and has a clip mechanism to secure it. Only the dome will be visible for a aesthetically appealing look.

Arm mount- Are designed to mount a vertical plane or post. Generally this camera serves as a deterrence as it protrudes from where its mounted

Pendant mount- are designed to hang  from a horizontal surface such as ceiling, post.

 In ceiling mount   Arm mount  Pendant mount

7. Wiring PTZ cameras 

(a) Wiring RS485 for Analog PTZ cameras

There are two ways you can successfully wire PTZ cameras 1. Daisy chain  2. Star or direct connection

 Daisy Chain connection

  Star or Direct connection

multiple ptz connection daisy chain multiple ptz connection

Note: Recommended cable CAT6e but CAT5e works fine as well. Use a single pair ex: solid blue and white/ blue, use the solid blue as the positive and the white/blue as the negative.

The main difference between daisy chaining or direct connection is on a daisy chain the cameras rely on each other. So if one fails the ones that follow the failed camera will not work. On a direct connection the cable is ran directly from each camera to the controller or DVR. I normally splice in a 2-3 ft. cable to make it easier to connect. If a camera fails none of the other cameras are affected and continue to operate as normal.

A Guide On Product Series and Product Technology

On you may have noticed the following logos in relation to our products. Well, excitingly enough, they are here to help as we grow. Elite and Techpro series products have been a staple to our product line up for quite some time now. As technology advances, the industry changes and customer demand increases we have add to modify our line up and this fall of 2015 we are happy to be introducing our new prime series to our product line up.

elite-cvi prime-TVI TP-CVI
elite-ip-network prime-ip-network TP-TVI
elite-series prime-SERIES TP-IP-Network

These product series labels were created to help you, the user, understand our product lineup and product compatibility features. Each Series is equal in quality, but the difference is in software and compatibility between products.

Shopping guideline

Step 1: Start with Technology

Under each series title you will notice the type of technology associated with it.



This is Important because not every product inside a series will be compatible. For example, an Elite Series Network Video Recorder (NVR) will NOT be compatible with Elite HD-CVI or Analog cameras and HD-TVI Cameras will not be Compatible with HD-CVI DVRs.

Just Because they are the same Series does not always mean they will coincide. Their Technology compatibility must be able to match up as well. Network Video Recorders must be paired with IP Network Cameras and HD-CVI DVRs Must be paired with HD-CVI or Analog Cameras. So along with each Series of device (Recorder or camera) be aware of each technology associated with it.

Technology Compatibility Breakdown:

HD-CVI Tribrid DVRs: Compatible with HD-CVI Cameras and Analog Cameras

HD-TVI Tribrid DVRs: Compatible with TVI Cameras and Analog Cameras

IP Network NVRs: Compatible with IP Network Cameras.

Note: if the NVR is ONVIF compatible the device has the ability to sense and search for any ONVIF IP Network Camera as long as both the devices, recorder and the camera, have ONVIF.

Technology Overview

What is HD-CVI? High Definition Composite Video Interface: This technology was developed by ZheJiang Dauha Technology Co.  Dauha made the technology open access in July of 2014 allowing other manufactures to utilize the technology and improve upon the chipset. The name has to do with its baseband and quadrature amplitude modulation technology which is able to avoid CVBS cross talk, completely separate the brightness and hue signal, and further enhances video quality.

What is HD-TVI? High Definition Transport Interface: It is a DSP-TVI technology developed by Techpoint in 2012. The chipset was sold and is now also open access allowing other manufactures to utilize and develop the technology. HDTVI technology can be implemented in an existing setup over coax  and produces reliable HD video signal transmissions over a single coaxial cable.

Both HD-CVI and HD-TVI are affordable HD over Coaxial cable solutions. The HD-CVI and HD-TVI chip sets have similar features and both can provide analog high definition solutions

Coax. Transmission Distance 1000 – 1500 feet 1000 – 1500 feet
Cat5 Transmission Distance 700 feet 329 feet
720p Supported Features (FPS) 25, 30, 50, 60 25, 30, 50, 60
1080p Supported Features (FPS) 25, 30 25, 30
DVR Features 720p & 1080p Signal Simultaneous Choose 720p signal or 1080p Signal. One or the Other


IP Network Technology Overview: IP Network Surveillance Systems provide the highest resolutions along with the most adaptable infrastructure. Our current product lineup includes cameras and NVRs that have resolutions from 2MP to 12MP (4K). IP Systems offer a few benefits over traditional CCTV, HD-TVI and HD-CVI. IP (Internet protocol) network surveillance systems have improved search and storage features as well as a more flexible infrastructure.

Step 2: Review of the product series


The Elite Series has been our staple series on up to this point. This series is primarily HD-CVI and IP Network Technology. The DVRs, NVRs and IP Network Cameras utilize the SmartPSS Software in this series. Elite Cameras work best with Elite NVRs and DVRs. NVRs that are ONVIF compatible will work with ONVIF Compatible cameras.


The Prime Series is new to the’s product line up. This Series is not an inferior series compared to the Elite Series. The Prime series simply offers features and software that are different from that of Elite series. The Prime series is primarily composed of HD-TVI Technology and IP Network Technology. It also has ONVIF compatible NVRs.

In best practice and for seamless integration we do recommend pairing Prime Cameras with Prime Recorders and Elite Cameras with Elite Recorders. Just remember to compose your set up with the appropriate technology.


The Techpro Series of Cameras have also been a part of for quite some time. The TechPro Series of cameras are openly compatible with the Recorders on the website. Simply utilize the appropriate technology when pairing these cameras with Prime or Elite recorders.

How do I know what camera series is compatible with my Recorder?

Under the Description Tab of each NVR or DVR product page. If you have questions regarding what cameras to choose we will gladly display the type of cameras that are compatible. See example image below.


We also offer a number of multi-technology solutions with Tribrid and hybrid recorders and with you receive flexible and affordable options.

Tribrids allow up to three technologies. As an example, most of the Elite Tribrids allow for all channels analog, all channels HD-CVI with up to two channels IP. Some Tribrids offer all channels for all three technologies. These recorders are designed primarily for Analog users looking for an affordable upgrade from analog. Pick a tribrid recorder and slowly upgrade to HD cameras as your budget allows. Just make sure to check under the description tab for a quick reference you your series and technology compatibility.

TVI vs. CVI, What is the Difference?

Written By:
Friday, September 18th, 2015


When it comes to the “New” HD over coaxial market, there are a couple, some say a few, choices on the market.  The 2 major players in the HD over coaxial market are HDTVI (High Definition Transport Video Interface)  and HD-CVI (High Definition Coaxial Video Interface).  There is a third lesser known technology, simply called AHD or analog High Definition.  Now you are probably sitting there saying to yourself, WTF is the difference between these technologies and which one is for me.  I will try to hopefully help give you some differences and benefits of the technologies

HDTVI (High Definition Transport Video Interface) and HDCVI (High Definition Composite Video Interface)

HD-TVI technology was created by a company called Techpoint in 2012 and backed by Hikvision around the same time.  This was created by a third party company to compete with a technology coming out from the factory Dahua, who was about to release HDCVI.  There have been rumors out there that someone planted spies inside of Dahua that learned what was coming and once pulled out they created the company called Techpoint.  But, I don’t think any of it will ever be confirmed.  Hikvision is the world’s largest surveillance manufacturer and backed by the Chinese Government and has backed Techpoint in this endeavor. It has brought us one of the biggest revolutions to the CCTV (closed circuit television) market since the creation of IP, internet protocol, cameras.

HDTVI like HDCVI both come from the same principles created by the TV industry with the government back mandate for a Higher Definition video transmission of all broadcasting.  This spawned a surveillance type known as HD-SDI.  In essence, SDI had major limitations with regards to the distance it could be transmitted.  This limitation was eradicated with the creation of the two new technologies.  HDTVI is able to send 1080p video approximately one thousand feet, whereas HDCVI can transmit 720p video upwards of sixteen hundred feet and 1080p video around the same distance (or as quoted by Dahua – three hundred meters). There are some other similarities and then again a few differences.  I will go into and touch on the important, or better yet, more necessary information to know so you can have a better understanding of the two technologies.

With HDTVI recorders, all of them from their simple units up to their largest unit are capable of handling analog cameras, HDTVI cameras, Hikvision IP cameras and Prime IP/HDTVI cameras.  Whereas HDCVI recorders from the base model all the way up to 16 channel recorders (also known as Tribrid DVRs) can also handle analog cameras, HDCVI cameras, Dahua IP cameras, ONVIF IP cameras, Prime IP/HDCVI cameras and Elite IP/HDCVI cameras.  As you can see, both of the technologies recorders can handle three different technologies in one recorder making them Tribrid DVR’s.  There are Tribrid recorders that can only handle their specific technology as well as the two other technologies.  The major difference between the two technologies recorders are the Dahua recorders can also handle other brands IP cameras and the Hikvision TVI recorders can only handle Hikvision IP cameras.

Now both companies offer some basic camera models to go along with their technologies.  For example, you can get a fixed or varifocal lens dome or bullet option from both platforms as well as a Pan Tilt Zoom.  With HDTVI, there has been a slower development of a variety of camera models available from the major player.  Dahua has a very wide product line available and backed by the factory.  Now, both technologies have had third party companies that have stepped up to provide the wide variety of product lines that the factories have neglected.  I personally like the standard housings from both factories, but am also a huge fan of some of the third party product offerings as they typically have a wider variety of colors and mounting options that the big boys have neglected to adopt.

I have always been a fan of third party cameras and typically find that you will get more options for a lower price point than you find from the major players.  Now the major players will typically have stronger warranties than the smaller factories, but bang for buck the smaller factories give you a damn good product.  I personally like the Techpro Series cameras for both HDCVI and HDTVI for the options that they offer and some of the form factors are more appealing in my opinion.  I have had and installed many of systems over the years, as I was an installer and integrator for several of years before coming on board.  I have found these newer technologies are as simple to use as the original Closed Circuit Television systems, with the major advantage of much higher definition and quality.


As you can see, there really is not much of a difference between these two types of technologies, outside of the major players in the industry backing them.  I have personally used both of their interfaces, applications for mobile devices, and CMS software and find them on a fairly level playing field.  Some of the major differences between them come in the Graphical User Interface or GUI for short.  For a first time user, they are both rather easy to get through, allthough I believe HDCVI has a slightly easier to use interface for the novice in the surveillance world.  The reason is that the interface has a better simpler layout than you find in the HDTVI system.  HDTVI has things nestled under different tabs, very similar to what HDCVI did in the beginning until the addition of the “Blue” user interface experience.    I guess the bottom line on this is… if you are starting from scratch either system will work for you, or if you are doing an upgrade from an existing analog system either will work.  Now if you have used Techpro Security Products DVRs in the past you would want to stick with the Elite line, but if you are starting new, the Prime line would be a good place to look at as it is a very nice and solid platform and generally a little less money.


So many options when choosing a DVR for Surveillance Video!

Written By:
Thursday, August 27th, 2015

So, you’ve had enough of hoodlums and thugs stealing your Garden Gnomes and knocking over your mailbox. And those employees! OYVAY! They keep putting Metamucil in the coffee. Before you choose a security recording device for your home or business, you should educate yourself on the different types of recorders as well as the most important differences. Let’s take a look at the options available and under what circumstances they are best suited.


You basically have two options for wiring up a security system . . . CAT5/CAT6 network cable or RG59 coaxial with a power supply (AKA Siamese cable). If you already have the network cable installed you can pretty much quit reading this now and take a look at our NVRs because most people will agree that IP will give you the best images with the highest resolution! If you don’t have network cable installed, you’ve got enough other options to choose from so let’s take a look at them.

  1. Analog – The traditional Analog CCTV surveillance system transmits data over Coaxial Cable and back to the DVR where it is digitized and stored on a Hard Drive using a FIFO (First in First out) method. Make sure you have sufficient hard drive space so that you won’t have to worry about recording over older footage. You can still view live streaming video or you can access recorded footage, locate specific incidents, zoom in on particular images and save those to an external device to present to the authorities if you ever need to. Analog is being phased out by manufacturers and is already getting harder to find, so if you still have analog cameras and insist on keeping those, you might want to consider getting a Hybrid DVR that handles multiple technologies including Analog, CVI and even IP. Remember, while 960H is a huge improvement over previous D1 resolution, it doesn’t even hold a candle to 1080p megapixel security footage!

  2. HD-CVI – Developed and created by Dahua, HD-CVI is one of the newer technologies and stands for High Definition Composite Video Interface. It allows users to transmit video, audio and control over the same coaxial cable that was previously only capable of transmitting video. With an unprecedented transmission distance of up to 1,600 feet, HD-CVI technology gives you tremendous versatility when it comes to camera placement and distance from the recorder. Because of the ability to utilize the coax cable for control, you can use the OSD (on-screen display) to adjust a variety of settings for security cameras including exposure, white balance, back light compensation, day & night selection, motion triggers, blocking, etc. Remember, HD-CVI cameras ONLY work with HD-CVI capable DVRs and vice versa! Check out our DVR-CVI8M-1080-DH-V2 that can accommodate 8 HD-CVI cameras OR you can mix any combination of Analog, CVI or 2 IP cameras for under $399.00!  

  3. HD-TVI – This was created jointly by Hikvision and Techpoint and because it was released a little later than HD-CVI, it isn’t as popular but there are some benefits. Hikvision has opted for somewhat of an “open source” in relation to component manufacturing. This has opened the market to over 100 different manufacturers who have/are developed HD-TVI solutions and has created more competition. HD-TVI recorders are compatible with any HD-TVI camera on any channel! Overall, under optimal conditions where you have all of the same settings, are using the same type and quality of cable, and have the placement of the cameras the same distance from the DVRs, you shouldn’t notice a difference in image quality. Based on some independent tests, HD-TVI offers the longest transmission without signal degradation across both RG59 and CAT5 (with balun) cabling. We will be carrying the HD-TVI technology shortly under our PRIME designation.
  4. >Hybrid/Tribrid – A combination of different technologies that work together in one unit. We offer a variety of Hybrid/Tribrid combinations that help you integrate your older analog cameras with newer HD-CVI and IP cameras. This works out great if you feel like you’re constantly trying to keep up with technology and have older cameras sitting around that still work. Hook them up and purchase a couple new HD-CVI or IP cameras. Some of our Hybrid/Tribrids offer full use of 16 IP cameras AND even give you the ability to double that number with an additional 16 analog cameras! Others like our very reasonably priced TRIDVR-ELE16ME are capable of handling analog, CVI and up to 2 IP cameras.


There are numerous options, and many people who are familiar with the different systems have their preferences already. This is nothing more than an informational article to help you compare these different technologies and decide what will work best for you in your specific situation. My personal take on this is that the Tribrid DVRs are the best value for your money since they allow you to be flexible and give you the opportunity to sample the different cameras, try different functions, and decide what technology works best for you.

If you happen to own a Medical Marijuana Dispensary or need to meet the state law requirements for a retail establishment, we are I-502 and Amendment 64 experts and we can help ensure that you will pass your inspection! If you’ve already created a site plan (it doesn’t matter if it’s a professional CAD drawing or a sketch on a napkin), you can simply email a copy/scan to us and we will help get you the best setup and best placement of the cameras so you can pass your inspection. You can be rest-assured when you are setting up your Marijuana venture because we back up our products for your I-502 and Amendment 46 Inspection with a Certificate of Guarantee stating that the system we helped you choose has met or exceeded all of the specifications that are needed to have you pass your inspection.

What’s the Difference Between a Hybrid DVR, Tribrid DVR and an Analog DVR

Written By:
Wednesday, August 26th, 2015

It used to be that there was only one kind of security recorder, the CCTV Analog DVR. Now there are a variety of technologies for surveillance recording such as Analog, HD-CVI and IP Network.

Analog DVRs can record up to 960H resolution and the cameras are connect directly to the DVR via coax cable.

HD-CVI DVRs can record up to 1080p resolution and use the same coax cable as the analog DVRs. This is a great choice to upgrade your surveillance to High Definition without incurring the high costs associated with re-wiring to Ethernet Cable.

IP Network Video Recorders (NVRs) can record up to 12MP and the cameras need to be connected with an Ethernet Cable (CAT5/6).

Now, there are security recorders that can combine these technologies all on one device and that is the focus of this article. I will be focusing on the security recorders that can record up to 32 cameras on one device. These are the 16CH Hybrid DVR, the 16CH Tribrid DVR, and the 32CH Analog DVR. All of these DVRs look exactly the same on the front as you will see in the following image.

32 Camera DVR

But, it’s the inner workings and the backs of these DVRs that are different.

The 16CH Hybrid DVR

This Hybrid DVR brings together two surveillance technologies (Analog and IP) on one recorder.

16CH Hybrid DVR Back
16CH Hynrid DVR – Can record up to 32 Cameras (16 Analog and 16 IP)

As you can see in the image above there are a lot of BNC ports where you would connect coax cable with a BNC Connector. The top row contains 16 Video-In Ports. This is where each analog camera gets connected to. As I said, this is a 16CH DVR but it will record up to 16 Analog Cameras (connected with coax and BNC) as well as 16 IP Cameras. Where are the connections for the IP cameras you might ask? That’s an excellent question. In order to record IP cameras (up to 1080p resolution) you will need to connect your IP cameras to a POE switch. That POE switch needs to be connected to the same network as this Hybrid and you will be able to view and record all 32 cameras.

The 16CH Tribrid DVR

This Tribrid can record all three technologies (analog, HD-CVI and IP) all on one device.

16CH Tribrid DVR
16CH Tribrid DVR – Can record up to 32 Cameras (16 Analog/HD-CVI and 16 IP)

In the above image you will see the same 16 Video-In BNC Ports as in the Hybrid. These are where you can choose to either connect analog cameras or HD-CVI cameras using the same coax cable. Again, just as with the hybrid, this 16CH Tribrid can record up to 32 cameras. 16 of those can be a combination of analog and HD-CVI cameras, or all analog, or all HD-CVI. The other 16 cameras can be IP cameras. The IP cameras need to be connected to an external POE switch as with the Hybrid.

The 16CH Analog DVR

This Analog DVR can record only analog cameras (up to 32) all on one device.

32CH Analog DVR
32CH Analog DVR – Can record up to 32 Analog Cameras

As you can see from the image above that this DVR has 32 Video-in BNC ports. This DVR can record up to 32 cameras like the Hybrid and the Tribrid, but it can only record analog cameras.

The Major Difference Between These Recorders

All 3 of these Security Recorders can record up to 32 cameras. The real difference is the ability to record in TRUE HD 1080p Resolution. The Analog DVR can only record in analog up to 960H resolution on all 32 channels whereas the Hybrid and the Tribrid can record in both analog as well as 1080p resolution. The Hybrid can record 16 analog cameras at 960H as well as 16 IP cameras at 1080p Resoloution. The Tribrid scores the best being that it can record either analog or HD-CVI on 16 channels as well as IP at 1080p on another 16 channels. But, the major difference here is that you have the ability to record 32 High Definition cameras at once on the Tribrid if you have 16 HD-CVI cameras and 16 IP cameras.

The similarities between these 3 units is that they all have the ability to record audio. They also have the ability to control other devices such as sirens, strobes and alarms using the alarm inputs and outputs.

Also, all 3 of these security recorders can hold up to 8 hard drives giving you up to 48TB of hard drive space.


Whichever device you choose, you can be confident that these units are powerful security recorders. They each come embedded with a high end dual processor and Linux Operating System. Also, they come equipped with an easy-to-use GUI Interface so they are simple to operate and configure. Which one should you choose? It all depends on whether you want to record in analog or High Definition. Also, whether you want to go with IP or HD-CVI for your HD recording. If you want the best of both High Definition Technologies (HD-CVI and IP), go with the Tribrid.

Even if you have an existing analog system and want to start upgrading to TRUE HD security recording, the Tribrid is perfect for you. Keep some of your analog cameras in tact and replace your old DVR with the Tribrid. And then you can start adding HD cameras at your leisure. If you are upgrading to HD-CVI you can use your cable and power that you used for your analog cameras right where they are. HD-CVI works on standard coax cable. If you are using IP cameras, just make sure you are using Ethernet Cable and connecting them to a POE switch as I stated above.

If you have any questions on which device is best for your needs, get in touch with one of our knowledgeable sales staff. Also, all these recorders as well as the cameras come with free tech support so if at any time along the way you need help on configuring anything, we are just a phone call or chat away. Most times our techies can even log into your recorder remotely and do all the configurations for you.
