Preparing the project

Let’s visit the customers!

To confirm what a customer really needs it is important to visit the site where the surveillance equipment will be installed. Read more about how to perform a site survey in the web article Site survey considerations.

It is recommended to bring tools like a lux meter, a distance meter, and a digital camera or video camera to document the site. These are important questions you need to answer when designing a system:

Which distances can we cover, and what is the available lighting?
What is the required field of view for each camera?
Which cameras and lenses are required, given the actual layout of the building?
What degrees of movement are there in the settings you will record?
What are the realistic mounting options? Are there obstructions or design changes not reflected in the drawings?
What infrastructure – such as cables, switches and computers – is already available?
Which functionality do they need, such as pan/tilt/zoom, audio, day/night functionality, input/output and connection to external equipment such as passive infrared sensors?

Taking IT questions into consideration

Working with network video surveillance combines expertise from two worlds: best practices for creating safety and security, and best practices from working with the latest technology. Different network technologies are used to support and provide the many benefits of a network video system.

To get the cameras and network up and running, there are some IT-related questions to ask yourself and the customer.
Is there an existing network infrastructure that can be used for surveillance equipment or do you need to install a new network?

What is the bandwidth capacityof the current network, compared to the capacity you need?
Who will watch the recordings, where are they located, and when and how often does this take place?
Which corporate rules do you need to consider before installing the surveillance equipment?
Which employees and people working for the customer are needed to succeed with the project?
How well accustomed is the customer to working with network video surveillance?
Do you need to collaborate with local IT staff, or another company that handles the network?
What kind of network topology will be the best for this customer?

Let the Partner Pages guide you

Once you have documented the needs of the customer, it is time to confirm their surveillance goals. 
Important questions to consider:
The bandwidth required for the whole system
The storage needs over time
Alarm functionality in all types of weather situations
Solutions, such as cross-line detection, people counter
Detection, recognition or identification of people and objects
Accessing data from the system
Required uptime for the system
The need for audio
Deterring people from performing unwanted activities
Improvement of traffic flow
Ensuring the white light or IR light covers the same fields of view as the cameras
Validating identification using the pixel counter

If the surveillance goal is to identify people that breach a certain perimeter, you can use the pixel counter feature to show the customer how your installation achieves this. The calculation will show exactly how many pixels make up the image of a person’s face.
