Building a monitoring system with high synchronization

[zud 0]

I want to build a patient monitoring system which will have a video camera monitoring a patient. The signals from the patient are recorded simultaneously and there should be high synchronization between video and the signal for proper diagnosis. I do not know how is high synchronization achieved. I need suggestions for:

- wireless camera that can be controlled remotely (I guess it should be a PTZ IP camera)

- how to achieve high synchronization (not sure if this depends on hardware or software)

 

what specifications should I looks for and what other devices do I need?

Where do you plan on deploying this solution?

It is for a medical research.

Only purchase hardware that can be externally sychronised by a common clock source - eg gps clock

could you please give some details or example?

Most professional network attached equipment (computers, routers, switches, NAS, servers and IP cameras) require a time source.

 

Devices can be set to run on their individual internal clocks or run on a network attached clock (or a device that is designated to provide the only time source).

 

An option that is sometimes utilised to source more accurate time is a clock source on the internet, or for 'closed' networks (i.e. no internet connection) an NTP server device can be used (see http://www.veracityglobal.com/products/networked-video-integration/timenet.aspx or http://www.wharton.co.uk/master_clocks/4860.htm)

 

These are in turn connected to a GPS device for very accurate time reference.

 

These types of systems are typically used in the broadcast industry, in large computer networks and in CCTV systems to ensure that all devices are synchronised to a common time source accurate to milliseconds.

 

Hope this helps
