Note: Outside, the transmission range of the camera is up to 100 metres, inside 

buildings it depends to a great extent on the construction materials used.

Tip: If your television set only has one SCART connection and you would like to 

operate other devices with it besides your new eBench surveillance camera (video 

recorder, DVD player etc.), you can connect the receiver of your surveillance camera 

system between video recorder or DVD player and television set. To do this, connect 

the receiver SCART-cable to the television set and the video recorder or DVD player 

to the receiver per SCART-cable. When the receiver is switched on, the signal of 

the camera will be received, interrupting the signal of the video recorder or DVD 

player. When the receiver is switched off, the television set will receive the AV 

signal again.

Once you have connected all the components together, camera and receiver must 

now be set to the same channel.

Channel selection on the camera

Remove the rubber cover from over the channel selection switch on the back of the 

camera. Choose the required channel by sliding the switch. Then replace the cover.

Channel and interval selection on the receiver

Choose the required channel by sliding the required switch to ON on the back of 

the device (see Figure 

).

The receiver receives signals from up to four cameras. If you have selected channel 1 

for the first camera, you must select channels 2-4 respectively for the other cameras. 

If several cameras are in operation, you can use the “T” switch on the back of 

the receiver to change the interval at which the receiver changes channels (4 or 8 

seconds), i.e. changes between the images of the individual cameras.

A red LED on the front of the receiver flashes to show which channels are set. If 

channel 1 is selected, the LED flashes once — depending on the set interval every four 

or eight seconds. If channels 1 and 2 are set, the LED flashes once and then after 

four or eight seconds twice etc..

Setting the image focus

Turn the lens protector (see Figure 

) as far as it will go anticlockwise and remove 

it. Then turn the focus ring to the right or left until the image is sharp. Now replace 

the lens protector by placing it back on the lens and turning it to the right.
