TOP TEN TIPS FOR PAN & TILT HEADS

We’ve already gone through in some detail, all the main key considerations for choosing / using a modern Pan and Tilt head. Now we can have a quick look back over the top 10 ‘must know’ things about these motorised marvels?!!

1) - Always pick a PT head with at least 50% more weight carrying capacity than the load being supported; if you don't, the picture above may just provide a clue as to what may happen next!

2) - Carefully consider the location for the assembly. If necessary provide additional environmental protection.

3) - Safe practice techniques, in particular for the electrical and physical installation should be a priority.

4) - When using Infra Red illuminators, the Over the Top (OTT) unit may well be more suitable than the standard Side Mount (SM).

5) - If the camera housing is to be fitted with a wiper, unless it's a‘Deep Base’ type, the OTT head may not be able to look down vertically.

6) - If intending to operate a variable speed or preset positioning set up, make sure the control system can support these operations.

7) - Wherever possible, try and use a terminated ‘flying control lead’ from the housing, which is then plugged into the P/T head.

8) - When particularly large and heavy Pan and Tilt heads are being installed, it may be worth ‘stripping down’ some of the detachable weight.

9) - With any load fitted high above the centre of gravity on an OTT head, try and bolt counterbalance weights below the horizontal pivot.

10) - Always make sure that a seperate steel cable safety lanyard is fitted to a secondary bolt, in case the support fails in high winds.
