Wired System


Wireless System

Since the first smart home system was developed, there has been an ongoing dispute about which solution is better: a wired system or a wireless system?
Many articles have been written on the unreliability of wireless systems or the countless kilometres of cables required to connect wired systems. The debate is gaining momentum especially with the emergence of a new technological standard – the “Internet of Things”.

The authors of these articles focus on what is most relevant to them and whoever commissions the text. It’s no secret that such articles are usually sponsored by companies dictating their content. The benefits of a given solution are usually proportional to the article’s price.
Which is why we decided to tackle the issue with facts and detailed calculations.
Many companies and developers encourage their customers to buy apartments and houses with wireless home automation systems. Wireless systems use radio technology, where all fixtures and installations’ control units are micro transmitters and receivers concealed in electrical boxes. Control units communicate with each other via radio waves that can be interfered by other devices, such as cell phones, gate remote controls, Wi-Fi access points and other equipment that uses radio waves. Wireless systems also require advanced automation control units, which significantly increase the number of elements needed for the system to function.
Wired systems don’t need transmitters and receivers. Control units, located in the switchboard, are connected to wiring. DEIMIC ONE is built entirely on regular electrical cables that just need to be arranged in a specific way, and UTP cables, which are among the cheapest electric cables, all connected to the main system switchboard. Such wiring guarantees quality and reliability of communication between all devices and installations that you want DEIMIC ONE to control.

Wired System

To best illustrate the difference between wired and wireless automated home control and management systems, we conducted a comparative simulation based on a sample property: a house of approximately 110 m2 (1200 sq ft), with modern LED lighting, remote controlled sockets, underfloor heating, a garage, roller shutters, garden sprinklers, one gate, outdoor lights and an alarm system.

This is a sample house with specific equipment and installations, where a home automation system fully manages the following:
- indoor and outdoor lighting
- LED lights with brightness control
- power sockets
- motion sensors
- alarm system
- blinds and shutters
- heating
- gates and garage doors
- garden irrigation systems and sprinklers

- mobile control via smartphone or tablet
- control via standard wall switches
- 18
- 4 LED strips
- 2 sockets
- 6 motion detectors
- on
- 5 blinds or shutters
- 4 heating zones
- 1 gate + 1 door
- 3 zones

- control app
- 50 switches

A detailed comparison of wired and wireless solutions, including a list of components and threats to the systems’ proper functioning:

Intelligent Home control and automation system
Number of elements in the whole system Central module - 1 pc

Blinds/shutters micro transmitter and receiver - 5 pcs
Lighting micro transmitter and receiver - 18 pcs
4 x LED micro transmitter and receiver - 1 pc
2 x gate/ door micro transmitter and receiver - 1 pc
2 x sprinkler micro transmitter and receiver - 2 pcs
Power socket micro transmitter and receiver - 2 pcs
Wall switch micro transmitter and receiver - approx. 10 pcs
Alarm system micro transmitter and receiver - 1 pc

TOTAL: approx. 39 pcs of different units and devices    DEIMIC ONE MASTER - 1 pc

Additional system components Motion sensor - 6 pcs
Thermal sensor - 4 pcs
Motion sensor - 6 pcs
Thermal sensor - 4 pcs
Interference with the system Bandwidth and radio networks interfering with the system:
- Broadband LTE networks
- GSM networks
- Public services radio bands
- Military radio bands
- Aircraft radio bands
- Microwaves
- Mobile phones
- Routers and Wi-Fi access points
- EPG encoded bands
- TV providers' uplink and downlink bands
Materials disrupting or blocking system operation Metal - 90% to 100%
Reinforced concrete - 50% to 80%
Hardened glass - 40% to 70%
Brick - 20% to 40%

Number of devices exposed to system failure Approx. 39 1 pc
Many online sources provide information on the difference in cost between regular and intelligent wiring. DEIMIC ONE uses structured cabling in a star topology (network configuration) both logically (information flow) and physically (cable network). The star topology allows to run a separate channel (cable) directly from every device or installation element to the switchboard, where the DEIMIC ONE Master module is installed.

Further advantages of the star typology:

- universal in ICT configuration
- easy to service and maintain
- resistant to mechanical damage
- easy diagnostics
- minimal chance of system failure

Below is an analysis of the wiring required to install DEIMIC ONE in the sample house.

Wire types:

4 x 1.5 YDYP / 2 x 2.5 YDYP / 3 x 2.5 YDYP / 100% copper UTP5e /
3 x 1.5 YDYP / 100% copper gel-filled UTP5e / 3 x 1.5 YKY

The total cost of cables required for the sample house is only 538,54 PLN!
