As we are currently installing two projects that require CCTV cameras in elevators, we thought this would be a good time to discuss different types of installations for elevators. One of the projects is a 16 story building in Makati and the other is an
Becuase these projects use IP cameras, we’ve opted to use a wireless solution for ease of installation.
Since we are able to install two or three elevators per day using the wireless solution instead of one elevator in three days using a wired solution we were able to offset the higher cost of wireless with lower labor and less in cable costs.
Installing CCTV cameras in an elevator can be a time consuming and complicated task. As elevators are moving objects, running wires can be a real challenge. Elevators normally use travelers to run wires and any new wires can be fed through the travelers.
The elevator company should make provisions for you to run wires through their travelers or you can install a new traveler. Over time it will become necessary to replace cables due to wear and tear of the cables moving. Wireless elevator installations do not have this problem.

We use Dahua, Hikvision and Ubiquiti products when installing CCTV in an Elevator. In this diagram, we have installed a wireless receiver at the top of the elevator shaft and a wireless transmitter on top of the elevator.
The camera is connected to the elevator power and the wireless transmitter using UTP cable. The wireless receiver “is connected to a data switch. The data switch connects to the backbone of the system and sends the data to the Network Video Recorder.

Cost and Installation
Wired
Wired CCTV cost less compared to their wireless counterparts, but are also known to require a more elaborate and complex installation process. They also take much longer to install depending on how many floors the elevator must travel. Wired solutions have higher labor and cable costs. A wired installation may use three to four installers per elevator.
Wireless
Wireless CCTV, on the other hand, may cost more but are relatively simpler to install as they do not come with multiple wires and cables. They cost more, but the prices of these cameras have been going down steadily. A wireless system can be accomplished by two installers.
Summary
When installing analog cameras we use a wired solution, but when installing IP cameras we almost always opt for a wireless solution. The ease of installation, savings in time and labor usually offset the cost of a wired solution and the system is much easier to maintain.
