VIDEO BALUN TR-4P
DESCRIPTION The TR-4P is designed to video signal transmission via twisted-pair cable. The device adapts the impedance of coaxial cable 75Ω to the impedance of symmetrical line, ensuring transmission of video signal up to 400m (twisted-pair cable category 5) and eliminates asymmetric interferences.
It is important to pay attention to linking the adequate terminals: (+) and (-). Reverse connection would cause distortion of image.
Designed to AHD, CVI, TVI, PAL cameras.

PRESENTATION
Example application for CVBS/PAL cameras:
1) Camera 1 2) Camera 2 3) Camera 3 4) Camera 4 5) Monitor 1 6) Monitor 2 7) Monitor 3 8) Monitor 4 9) Coaxial cable 75Ω 10) Twisted-pair cable
Wiring sequence inside the RJ-45 plug. Plug wiring sequence is consistent with the T568B standard:
1) White/Orange - camera No.1 signal (+) 2) Orange - camera No.1 signal (-) 3) white/green - camera no.2 (+) signal 4) blue - camera no. 3 (-) signal 5) white/blue - camera no. 3 (+) signal 6) green - camera no. 2 (-) signal 7) white/brown - camera no. 4 (+) signal 8) brown - camera no. 4 (-) signal A) Camera 1 B) Camera 2 C) Camera 3 D) Camera 4
OUR TESTS Amplitude - frequency response - 2 transformers connected briefly (RF PWR OUT = 0 dBm):
OUR OPINIONS A very important issue is that the mass signals are isolated from each other!.
