If you own a CCTV analog security system, then you know the headaches of trying to make a positive ID of a criminal when it comes to your security recordings. After you experience a theft, vandalism or any other criminal act, you rely on your security camera system to provide you and the authorities with as much detail as possible. As you know, when you digitally zoom in on your recordings to see the criminal’s face or tattoo, for example, you experience image distortion. You might even have been frustrated in the past because of this “pixelization” that occurs. You have always wanted to upgrade your system to High Definition, but were afraid of the high costs that used to be associated with this. Well, in this article I will explain just how upgrading from Analog to HD-CVI is an affordable approach to High Definition Security Recording.
What is HD-CVI?
High Definition Composite Video Interface (HD-CVI) is an amazing technological advancement in High Definition Security recording. It allows CCTV Analog users like you the ability to keep your standard coax cables and power right where they are. All you need to do is just swap out your old, outdated DVR with an HD-CVI DVR and replace your cameras with HD-CVI security cameras. That’s right! High Definition recording can now be transmitted through standard coax cable. Before, the only way to get HD was to replace all of your cable with Cat5. That is very expensive since you need to either take time out of your work schedule to do that or hire an installation company. On top of that, you would need to hire an IT professional to figure out all the networking for you, if you didn’t have time for tech support or don’t posses the networking knowledge. Already, upgrading your analog system to HD-CVI is saving you a lot of money by not incurring the extra cost and hassle of re-wiring.
Another benefit of HD-CVI is the ability to control the On Screen Display (OSD) right through the DVR. Remember when you were setting up your analog cameras and had to control the OSD directly from the camera? You had to go up the ladder, make your changes, and then go down the ladder. What a hassle that was. Now, with HD-CVI, you can connect all of your new cameras (on your existing wires), and then tweek your settings through the DVR interface (from the comfort of your chair). PTZ control is also another advancement in HD-CVI. If you own an analog PTZ you know that you have to run an extra set of wires to the back of the DVR. You do not need to do this with HD-CVI as all control of the PTZ is transmitted through the video cable.
How does HD-CVI resolution compare to Analog?
As you can see by the pictorial above, HD-CVI High Definition recording will give you a greater advantage in making a positive ID on a criminal. The reason is since the image is greater in pixels, you will be able to zoom in more digitally, without the distortion that you experience in your analog system. As noted, these images are not the actual size, but they are scaled down for comparison purposes.

How easy is it to install an HD-CVI System?
From the image above you can see that both an Analog DVR and an HD-CVI DVR have the same Video Inputs. That is why you can leave your coax cable right where it is. When your new HD-CVI DVR arrives, all you need to do is disconnect the video cables from your old DVR and connect them to the new DVR. It’s that easy! Also, if you have any connections into the audio ports, video out, Ethernet, Alarms, etc., just plug those exactly into the same corresponding spots on the new HD-CVI DVR.
On the camera side, the connections will be as easy, but the installation will take a bit of work. It all depends on how your cameras are installed. You will first need to unscrew your old cameras from the wall, ceiling or wherever they are located. Then you will disconnect the video cable and the power cable from the camera and attach them to the new HD-CVI camera. After you have done that you can attach your new camera to the wall or wherever the old cameras were mounted. That’s it. Just turn on your new HD-CVI DVR and start configuring the settings as you had done with your existing analog system. Except, now you can finally record in High Definition!
As you can see, purchasing an HD-CVI System is around half of what you would pay for an IP Megapixel System. Of course, if you already have your cables and power in place, the cost is even lower. Plus, as I had stated above, if you upgraded to an IP system you would need to replace all of your existing wire and learn how to network (or pay an IT guy to figure it out for you).
When you take into account that the system as a whole is less expensive than IP, and that you can keep your cables and power in tact, HD-CVI is definitely an affordable approach to High Definition Security recording.
You will be amazed at how crisp and clear your recordings will be with High Definition recording. Imagine if you ever experience a break-in or a car accident in your parking lot. You can give your recordings over to the authorities with confidence knowing they will have an easier time making a positive ID with your High Definition recordings, than with your Analog D1 recordings.
That is the main benefit of HD-CVI. High Definition recording at an affordable price. If you have been on the fence about upgrading your CCTV analog system to HD, I hope this article will help you with your decision. You aowe it to yourself to be able to see crisp detail in your recordings and catch that thief!
