What is the voltage tolerance of AUTODOME IP starlight 7000i?
Question
Let’s suppose that in your project you have a long Ethernet cable lengths and small wire diameters. In this case, it might happen that there is too high-power loss in the cables and that the cameras might receive too less power.
The question here would be: when does the camera exactly starts logging power supply errors or fails completely and shuts down? What is the voltage tolerance of AUTODOME IP starlight 7000i?
Answer
- Be aware that Bosch requires the installer to provide the specified power mentioned on the product spec sheet and labels. While taking into consideration the POE standards.
- Bosch doesn't support out-of-spec operation of our cameras as we cannot guarantee proper functionality in such circumstances. Thus, we will not be providing out-of-spec voltage or power values at this stage.
According to the AUTODOME IP starlight 7000i datasheet:
The camera can be powered by one of the devices in the list that follows:
- a 30 W (IEEE 802.3at) midspan
- a 30 W network switch
- a 60 W midspan
In a PoE configuration, a single (Cat5e/Cat6e) cable connection provides power while simultaneously supporting data and video transmission. For maximum reliability, the camera can operate in a redundant configuration, with both a 24 VAC power source and a midspan or a switch connected simultaneously. If either power source fails, the camera switches automatically to the other power source. The camera can also accept a standard 24 VAC power source if a PoE network interface will not be used.
For pendant models used in outdoor applications that require heaters, a 60 W Bosch midspan or a 60 W switch is required to power both the camera and its internal heaters.
For in-ceiling or indoor pendant applications that do not require heater power, a standard 30 W (IEEE 802.3at) midspan or a 30 W switch can be used to power the camera.
A POE+ supply is only ok if no heater is used. If the heater has to be used, then High POE needs to be used.
POE+ and High POE provide by definition a voltage between 42,5 and 57 VDC, the Bosch POE midspans provide typically between 54 to 57 VDC.
POE's standard has a known limit of 100 m (330ft). Bosch does not promise or test beyond the 100 m IEEE Ethernet standards.
You will also see in Installation Manual that the spec is also listed (Page 56 - Section 14.1).
- As seen on the Datasheet
- The Status codes detailed in the Operation Manual (page 72) will be displayed in these situations.
