Get This if Someone Needs to See What You're Doing!

This is the perfect purchase if someone nearby needs to see what you are shooting. They don't have to sit or stand right behind you anymore! Also perfect if you have a second shooter and they need to see what you're doing, so they can get a different composition. This receiver/transmitter set contains one AC power supply, so you need to have at least one Sony NP battery (or another AC power supply).

Great transimitter and receiver pair - very less to no lag

I use this for indoor events and use this on my 2nd or 3rd camcorder that is on wheels (tripod on wheels) for capturing different angles.. It works great for large auditoriums and I always kept the receiver and transmitter in line of sight. I have not tested this across walls but, the range I get is really good. I have used it in event halls where the receiver and transmitter have been placed over 300 ft away. I primarily use this for mixing for live-streaming

Great system at a reasonable cost!

I have used this system to livestream baseball, basketball & cross-country events. With the addition of enhanced antennas, I get well beyond its rated distance specs. This system has performed very welI for me. I purchased an open box unit on Adorama for less than $400 and it looks like a new unit. I have 2 of these systems.

Works great

Works well, If your going thru a fast speed , say car chasing scene I would recommend mounting the receiver closer to the source

Game Changer in wireless video transmission

Quick shipping and they work better than expected. Although I will never need to go further than 400ft, these got me closer to 600ft.

Best thing I bought in a while

A must have for DP's... sometimes the signal drops, but not often enough to be a problem... worst case, just turn off then on. Works right out of the box, just attach the antennas

Almost professional

Overall I think this is a great unit. I have 2 receivers and it?s a god send to not have to run cables all over auditoriums. Pros - Convenience, They work through concrete walls. Cons - No loop out on transmitter / Delay is just noticeable enough to be an issue for discerning ears.

Super great unit. Latency is really not that bad especially if you are using SDI. There is slight latency via HDMI and that is manageable. Overall great product that I would definitely buy again. If you want to keep client/Director from breathing down your neck to look at picture on camera - this is the product for you!
