HollyLand Cosmo500 Wireless Transmission System

I was in the crossroad to select my Wireless Video over 150m range. I have narrow down to 2 choices based on what is best available in the market
ie 1. Vaxis Storm 500+ vs Cosmo500

Both technical features look very similar and having very closed price point. However after the physical touch of the both product, here is my finding. I would stress only on the differences rather than the similarity which has been mentioned in many reviews.

1. Battery –
The RX and TX of Cosmo500 can be powered by NPF970 battery, while Vaxis storm 500 , its TX uses NPF970 and RX uses V mount battery.

2. Interfaces
The Cosmo500 supports HDMI x1 and SDI x2 on both RX and TX. while Vaxis has one each of the HDMI and SDI, It offers no loop thru in this case as compared to Cosmo500

3. Design
The SDI port of the Vaxis is protruding out from the unit, While it is flat or hidden in the case of Cosmo, less prone to damage

4. Antenna
Cosmo500 come with a pair of Mushroom Antenna while Vaxis does not.
Mushroom antenna is designed for FPV flying performance. as the Transmission pattern is of circular polarized.
Good for transmission over different in height situation
Antenna mount protection is supplied for Cosmo500 while Vaxis does not

5. Future upgrade
Cosmo500 come with a USB port which is designed for the possible future upgrade of the equipment.
Vaxis does not have this in place.

6, SDI Cable
Vaxis supply 1 x SDI cable in its standard supply while Cosom500 has none.

7, Display
Vaxis offer an OLED screen Display , Comos does not.

8. Re-connection
We have tested both speed on how fast will they re-connect after losing the signal
1. Cosmo 500 : less than 2 sec
2. Vaxis 500 : about 40 Sec

9. Synchronous recording
Cosmo500 supports Trigger synchronous recording, and it is fully compatible with the recording of the camera with 25 bars /50 bars /96 bars /100 bars, saving time and energy, this information is not available as in vaxis Spec

10. Availability
I wrote the above on the 1st Mach 2019, however I discovered it has been announced discontinuation of Vaxis storm 500+ .
Nonetheless there is some stock still available in the market
Csomo500 was introduced to the market in year 2018 December.
