we are using pelco ptz dome cams in one of our casinos, they moved around the tables now we have a problem with the lights.The cards look too bright and cant make out the value on them we ask to put the lights in an angle on top of the tables and use 75 watts insted of 150 watts that they have now.Dont know if that would help but if anyone have had this problem please let us know what you did. Thanks and have a nice day...

The two main keys to seeing the cards on tables are:
* Use diffuse light, as in floods, not spots.
* Try to keep the lights on the same side of the table as the cameras to prevent light from reflecting back into the camera. Watch your angles - adjust the angle from light to table so that it is not equal and opposite to the camera-to-table angle. This will help prevent light from reflecting back to the camera.
* Light the table evenly, minimize "hot spots". Remember the camera is much more critical of lighting variations than your eyes.

Survtech thanks for the quick respond, right now they are using 2 big spot lights 150 watts each. The lights are in an angle towards the table and the ptz we are using to cover that cam is about 5-10 feet in Front of the table.Do you think moving the cam to an angle as well would help :?: I will ask to change the lights to diffuse lights to see what will happend and keep you inform. Thanks and have a nice day...

sorry i ment about 15 feet just above the table.

First, I would have them switch to flood lighting instead of spots. Spots tend to concentrate too much light in one small area where on tables (actually anywhere for camera coverage), you want a more diffuse source.

Also, lowering the wattage may help. We typically use 2-3 65 to 75 watt floodlights in cans for each table.

As far as the angles, just make certain that the lights are not at an equal and opposite angle to the table(s) as the camera(s). We prefer to put the lights on the same side of the tables as the fixed cameras (approximately over the player opposite the dealer), and the PTZ's on the sides of a group of tables (at the corners of the pit in line with the table centers). That allows us to use the PTZ's on one side of the pit to look at the table surfaces of that side of the pit or to see the players on the opposite side of the pit.

Something unrelated to PTZ's - if you do have fixed cameras on each table, turn off AGC. That tends to muddy things immensly.
