Outsourcing Models
We understand that a personal and custom tailored approach to our clients’ needs, strict deadlines and clear communication makes co-operation easier, and therefore we try to be as flexible as possible. Our experience enables us to effectively differentiate between the most requested business models in order to best accommodate our clients’ requirements:
  • Extended office model - This model is implemented by a fixed time allocation of our engineers for clients' looking for an extension of their own resources. A 6 month minimum contract is necessary to provide this model. Rates with favorable conditions apply.
  • Turn-Key model - In this model, projects are fully managed by OXY. Both sides have complete understanding of the project before the project is approved and development is started. Services are priced prior to a project, on the grounds of related specifications.
  • On-site development - Our engineers are prepared to work abroad as much as a project demands. The terms and costs of such a contract have to be agreed and regulated in advance. Usually an additional fee will apply.
  • Partnership - From an organizational and participation point of view, this is a full custom model. It is shaped so that the parties get the most out of it while sharing the same vision.
If you aim to establish a lasting partnership, we are ready to demonstrate our skills and service quality with no risk to you.
As a high end engineering company, headquartered in Belgrade, Serbia our work is mostly focused on foreign markets, and the majority of our clients are EU based. As such, we ensure a high level of security for our customers, protecting their Intellectual Property with strict NDA implementation.

PINOLLO
SMART ADDS KEY FINDER
DESCRIPTION
Pinollo is a bluetooth low energy (BLE) device which is used as a key-finder device. User can access last seen location of tracked item and is alarmed when he/she goes out of BLE signal range. Additionally, the Pinollo device itself can be used as a remote shutter for camera and dictaphone, and can also be used to find a missing phone.

Design, mobile app and BLE device’s firmware was also done by OXY engineers.

The challenge was to find the balance between phone energy consumption and app functionalities.

Smart Containers
DESCRIPTION
A part of Smart City project in municipality of Münich. This device is mounted in big secondary waste containers. It monitors the container load capacity and alerts when containers are 70% full. Onboard display is used to setup and configure load cells capable of measuring a waight of several tons.
Both GPS and GPRS are used to constantly monitor and report container position and conditions.
Beside those main functions, it also keeps a record of temperature and humiditiy. External antena connectiors are also supplied.
It can operate up to 2 years without replacing the battery.

Often the waste is more valuable that the container itself. So the data collected is also used as a part of security system besides collection and transportation optimization means.
