So would you like to play "Spot the CCTV Camera?". Eagle eyed visitors may recognise the profusion of street furniture, surrounding a single heritage dome camera keeping watch over part  of Londons' prestigious Oxford Street shopping area.

CCTV cameras on the move


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.
