Tell us what components would need to be checked before connecting a CCTV camera to a TV?


☛ First, make sure the camera channel or the RF modulator use a channel that has no local TV station.
☛ Then, check the level of power output on the modulator and accordingly, use a coaxial cable to connect the RF output to the input on the booster.
☛ Next, measure the input on the booster and depending on the input, use a mixer to feed the coaxial output of the RF modulator.
☛ Finally, if the booster appears to be a split type and your TV channels receive signals through aerial connection, then using a pass through type of mixer will be recommended.
