TESTED: The March Networks 30670 CamPX Dome

by Andy Clutton

Marchdometest2The March Networks 30670 CamPX Outdoor Dome is a high performance external vandal resistant IP PTZ dome with a 36x optical zoom capability. It is strong on features and without unnecessary gimmicks. The standard of documentation is extremely good with a clearly written 20 page installation guide and a comprehensive 77-page configuration manual. The tested dome was supplied for pendant mounting; wall, corner and pole mount brackets are available to suit the installation.

The dome housing contains a PCB under a fold-down panel. This PCB includes an impressive array of surge and transient suppression devices to all relevant external connections; these are stated to provide protection to ± 2000v.

Dome Pan and Tilt drive is by way of identical stepper motors using toothed drive belts. The camera module appears to be of Hitachi manufacture and provides good colour rendition and low noise performance. A single circular PCB holds the main processing and drive components. A socket at the front of this board is provided to accept the SD card.

Major components such as the camera module have locking compound added to their fixing screws to secure them and potentially to identify if items have been replaced.

Once the polystyrene transit wedge has been removed from the module the dome can be fitted into the housing. Fixing is by way of two latching lugs either side of the assembly. These are colour coded to the housing to ensure it is fitted the correct way round. Two eleven way in-line connectors in the base mate with the assembly to provide all signal paths.

A fair degree of force is required to latch the dome in place and it is essential to ensure that both latches click home. Two M6 hex bolts and spring washers are supplied to fully secure the dome to the base support plate.

All of the major components run at relatively low temperatures which should help to extend the life of the product.

A heater and fan arrangement is mounted onto the dome assembly to channel warm air across the face of the clear dome to prevent condensation.

A clearly identified 13mm OD multi-core cable of approximately 1 metre length is terminated in the following flying lead connectors:

  • Power in – 2 x screw terminals
  • Network – RJ45
  • Alarms – 10 way push-fit terminals
  • RS485 – 2 x screw terminals
  • Video O/P – BNC socket
  • Audio O/P – Red phono (RCA) socket
  • Audio I/P – White phono (RCA) socket
  • Ground – Green/Yellow wire with eyelet tag

On power-up the dome goes through the usual power-up routine to establish its datum reference points and then is available for software configuration or control.
