Preparing the project
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 such as a lux meter, a distance meter, and a digital camera or video camera to document the site.
There are several important questions that you need answers to 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 actual 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 is required? This might be PTZ, audio, day/night functionality, input/output connections to external equipment such as passive infrared sensors?
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 learn more about working with network video technology we recommend Axis’ Technical Guide to Network Video.
For basic knowledge about networking, see our online course Introduction to Networking.
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?
Once you have visited the customer, Axis partners can contact Axis presales engineers for extra support when working with customer projects.
Axis Partner Pages keep you updated with the latest news and allow easy communication with your sales contacts at Axis. Read more about the Axis Partner Network.
A central source of knowledge for our partners is the Axis Channel eNews, which features news, tools and services, product news, case studies and more. If you’re not currently a subscriber to Axis Channel eNews, get in touch with your Axis sales contact.
Once you have documented the needs of the customer, it is time to confirm their surveillance goals. Some important questions to consider:
- The bandwidth required for the whole system
- The storage needs over time
- Alarm functionality in all types of weather situations
- AXIS Camera Application Platform (ACAP) solutions, such as cross-line detection, people counting
- Detection, recognition or identification of people and objects
- Accessing data from the system
- Required uptime for the system
- Requirements for audio
- Deterrence effects
- Improvement of traffic flow
- Ensuring the white light or IR light covers the same fields of view as the cameras
If the surveillance goal is to identify people crossing a perimeter, you can use the Axis pixel counter feature to show how the installation achieves this. The calculation will show exactly how many pixels make up the image of a person’s face.
By having people purposely breach the perimeters from different angles, you can use the pixel counter to see how you can optimize identification.
To learn more about pixel calculations, we recommend you read the web article Perfect pixel count.
