  • The coaxial cables can be extended to at least 500m. The best part is that it does not require highly functional coax cables. In case, you possess cheap ones, you can expect it to work just fine.  You will be able to hear clear audio signals through this cable.
  • Additionally, you can transmit RS485 data over the coaxial cable and tilt or zoom the video as you like.
  • You also have the facility of running video transmissions even with a twisted wire.
  • Till now, there has not been one incident regarding transmission delay.
  • You will never face any IP configurationissuesbecause this digital signal doesnotutilize internet protocol.
  • The video does not get compressed, therefore, you will see every footage in real time.
  • It does have the necessary requirement of long network bandwidth, as it can work just fine without it.

Note: You have to carefully finalize your surveillance system and then work hard on setting it up. You might have to spend some fortune in upgrading your alreadyexistingcamera system. However, consider it as a one-time investment that definitely will be fruitful in the long run.


What’re the differences between HD-SDI, AHD, HD-CVI, and HD-TVII


It is a known fact that the HD format hasevolved at a rapid pace. The main formats are HD-SDI, AHD, HD-CDI, and HD-TVII. All these have similar basic functions, with some unique characteristics of their own.

Given below are some of the main capabilities of each of the HD formats.


As compared to HD-TVI, HD-SDI format presents an excellent 1080P/720P video resolution quality. It covers a total transmission distance of about 150 meters. Likewise, it offers low transmission reliability as well as anti-interference in most cases. It also requires extra equipment when pursuing RS-484 coaxial cable. The only thing that is similar in both of them is that there is no delay in transmission.


In simple words, AHD and HD-TVI are considered as two different technologies that have a similar function of supporting 1080P resolutions over the standard coax cable. Moreover, its video output quality is low in comparison to HD-TVII. It contains analog cameras, which provide quite a few configurations and less number of channels. With that said, this type of HD format also seems to have good DVR compatibility. Lastly, of all, it does not follow IP protocol and this is one feature that makes it different from other formats.


The thing is that HD-TVI and HD-CVI have very less to no differences at all. Its coax cable covers the same distance as that of HD-TVI and half the distance of a twisted cable. Its fps of 720P and 1080P lies within 25/30/50/60, which is same as HD-TVII. The only difference is that it’s DVR can either mix with 720P and/or 1080P at a time.

One thing that each of these formats has similar is the 1080P video resolution. However, as mentioned above, HD-TVI and HD-SDI have better video quality.

Now, different people have different preferences when it comes to HD formats. However, if you need one suggestion, then HD-TVI should be your top priority. The reason is that it facilitative theusers with the longest video transmission. Last, but not the least, you can connect it with any DVR channel. Among a whole lot, it is probably the only format that is compatible with other IP cameras. All these features are surely going to help you in so many ways.

Compare Analog camera to IP camera


The biggest difference between these two types lies in the delivery of the video signal. An analog camera transforms the signal into a format compatible with a TV/Monitor. The IP camera, on the other hand, decodes the video signal, which later digitalizes it. After which, the camera can be connected to an internet connection and you can watch live video feed at any given time.

Analog cameras are available at a lower cost as compared to IP cameras. Furthermore, these cameras come in all sizes, therefore, you may use them according to your requirements. However, these cameras lack a number of features that are deemed necessary for maximum security.

The main issue is that it does not allow digital zoom. Many people have also reported a few interference problems. In case, you intend to set up a wireless surveillance system, then it might not work as you want. Due to this fact, the incoming signals are not easily encrypted. As a result, anyone can have a sneak peek of the signal. This is by far the biggest deal breaker that has caused many people switch to IP cameras.

Lastly, analog cameras also face difficulty when it comes to long-distance applications. In case, you need to cover a wide area, then you must switch from analog to IP camera.


Why Should You Choose IP Cameras Anyways?


A single IP camera can efficiently replace 3 or 4 analog cameras. With the upgraded feature of PoE (Power over Ethernet), you can run the signal and power.

In addition to high-quality video, IP cameras provide the best resolution. You can further zoom the image to a distance of 100 ft. The resolution is normally a lot higher than an analog camera.

Whenever it captures a photo, it translates it into a digital image. Later on, it enhances this image in a discrete way so that everything can be easily recognized. With the facial recognition feature, you can certainly identify different people. Not only this, you can also distinguish the licenseplate numbers.

Note: Motion detection and compression of the specific image happens the minute after the image is processed. This image is then streamed right from the camera and you are able to see LIVE Video. With that said, you can also know the exact location. Whereas in case of an analog camera, you will have to wait till the video is loaded on the hard drive. In different cases where time is of the essence, you should right away shift from analog to IP camera. The Network Video Recorder software is used by IP cameras and work better than DVR software of the Analog Camera.
