Buying Guide

With the increased use of the internet and social media, the need for more engaging content has brought us creating and transmitting live videos. As the demand grew, more and more manufacturers have entered this market, diluting it and bringing the prices down. Today, these devices and similar others are available at very cheap rates.

To make sure you don’t end up on the wrong side of the bargain, I have developed this brief buying guide for your assistance.

Transmission and input resolution

As there are different types of video transmitters available, when you are shooting on set, then the image quality is going to be important. So going for a low-resolution video transmission option is not a good choice here. Most of the pro video transmission systems can support 1080p 60HZ that works well for your video needs.

Do you also want to know the number of monitors that can transmit your video? For example, some devices can transmit a video signal to four different receivers at a time.

Distance of transmission

Many manufacturers advertise their products’ transmission distance right in the product’s name. But you will need to dig a lot deeper than that to find the right numbers.

In most cases, the numbers are in the range of line-of-sight. Therefore, you need to look for a product and its line of sight distance to find out the distance of transmission it can cover.

Interferences and supported frequencies

Most of the wireless systems work in a 5GHz frequency band, and you don’t need a permit for this. But it can be slightly problematic because many other devices and appliances use the same frequency. Therefore, these devices also feature automatic frequency ranges. There are HDFS/non-DFS frequencies available, too, with such a system, a device will check whether there is some activity going with the current frequency or not.

Redundancy and cross-conversion

If you are on a heavily loaded frequency, then you will need to make sure that your transmission gets through to the destination. Finding a clean wireless channel is one step, and getting redundancy of multiple points is another. You can do this by adding a remote management system to your network flow.

As most professional transmitters can transmit to multiple receivers at the same time, RMS systems can input signals for different receivers and switch them easily without a failover time.

Security and encryption

When working on a high budget project and working with highly sensitive media, then you will need encryption and security. With this technology, you can scramble your transmission until some decode it with the right key on the other end.

The key will be entered on the other end to receive the transmission, or the transmission will remain scrambled. It can save any sensitive information from hackers or prying eyes.

Mounting options and power

You will be in a better position to have your access to your transmission when you have better battery options different transmitters from different manufacturers have different battery needs. But a separate or a spare battery back is always beneficial. Similarly, mounting will also make sure that your device remains safe as it is working, and there are no dangers of losing or falling on the ground.


Is there any delay in the transmission of these long-range video transmitters?

In most cases, the delay is going to be around 0.15 seconds if you are using 5G Wi-Fi. This delay will be significantly dependent on the Wi-Fi on the field.

For example, if the internet is crowded, there will be interference, and the performance will get affected. The delay in such a scenario will be longer. But you can also use the smart scanning of channels to find out the workable channels, and you can also choose less delay mode.

Is there any way I can use it with an app on my phone?

Yes, these video transmitters now support Android and iOS apps. You just need to download the app named “HollyView,” and all the instructions will be right there on the screen for you to follow.
