I need your help with my system regarding a 12V IP camera (non-poe)

TP-Link TL-POE160S (PoE Injector) (48V 30W)

80-90 m Besta 23 AWG outdoor (CCA)

OE-B1210 splitter (48V 12V 2A)

Dahua HD - IPC-WPT1539DD-SW-532-PV (non-PoE) (12V)
(Power Consumption:
Basic: 2.6 W
Max.: 10.6 W (streaming + IR + siren and light active deterrence)

The seller said the following about the splitter listed:
We recommend operating at approximately 70% of the maximum value for safe operation. In other words, for a 12V / 2A max splitter, a load of around 1.4A is considered safer for continuous and stable use.
I need to set up this system as a plug-and-play solution. Has anyone here done something like this before? I currently have the camera but not the other components; if you give the green light, I’ll purchase the other parts and get it running.
 
+1^^^.

Also, you are planning to use te Wi-Fi, not the Ethernet, correct? I ask because that splitter provides only a 12VDC output from the POE, there is no data output from the cable provided for the camera.

EDIT: Ignore the above, my mistake, is see now that unit DOES provide a data output.:cool:

No, I’m not using Wi-Fi; the camera has an RJ45 port which provides its internet connection—the principle is the same, the only difference is that the camera runs on 12V. I’m using a Mercusys MS105G switch for the internet; I need to install the camera about 145 or perhaps 155 metres away, and there’s no power supply at that distance. The setup is as follows

TP-Link TL-POE160S (PoE Injector) (48V
The Mercusys MS105G switch meets the camera’s internet needs. I connect a short Cat6 cable to the PoE injector, then a 65m Cat6 cable to the Dahua PFT1300 PoE extender
30W) 65m Besta 23 AWG outdoor (CCA)
Dahua PFT1300 (PoE Extender) 80–90 m Besta 23 AWG outdoor (CCA)
POE-B1210 splitter (48V 12V 2A) Dahua
The splitter steps down the 48V power from the Cat6 cable to 12V, separating both the internet and power supply to deliver them to the camera

This is my plan, but as far as I understand, this isn’t something that can be done with CCA cables

I understand how splitters work, I just overlooked the specs on that model and edited my post.

Regarding the CCA cable, I think @VorlonFrog was pointing out that CCA cable, (that can, in fact, be used to provide POE to the splitter) is not recommended for Ethernet cables, especially when POE is involved. Solid, pure copper with a jacket rated for the application is the way to go.

You’re right. Buying a 48 V PSU, using a 2x2.5 mm² copper cable, and stepping down the 48 V to 12 V for the camera ultimately reduces costs and eliminates interference from intermediate devices (devices like POE extenders). It results in a seamless, single-piece cable run, which reduces costs and ensures a long-lasting connection. Rather than spending money on devices like Cat6 23 AWG copper, splitters, or POE extenders, buying the power cable makes more sense – the risk of interference drops to zero. I think I’ll go ahead and do this.
 
I'm not sure why you thought I recommended NOT using POE. That said, I'd double check your calcs regarding the size cables needed to supply that amount of current at that distance.

This calculator says that 2 each 2.5 mm² copper cables (two #14 AWG) supplying 1.0 amps out to 150 meters (500 feet) will allow a voltage drop of 1.55 volts, an unacceptable percentage of 12.95%. The voltage at the end only 10.45 volts.

Less than 5% is more acceptable as when using two #10 AWG conductors (5.26 mm²).

The POE system has been abandoned due to potential faults in POE extenders over time, their susceptibility to humidity and external environmental conditions, and the need for maintenance. Instead, a more robust and long-lasting solution has been chosen, which does not require additional active devices (such as POE extenders or injectors).

Power will be transmitted over a distance of 200 metres using a robust, thick 2x2.5 mm² pure copper power cable at 48V DC. At the end of the line, the 48V supply will be stepped down to 12V using high-quality DC-DC converters at each camera point to power the cameras.

This method carries a lower risk of failure compared to a Cat6 23AWG cable + POE extender system, requires no additional active devices, has minimal maintenance requirements, and operates stably for many years. In terms of cost, it is comparable to a POE system overall, but it is a far more durable and reliable solution against outdoor environmental conditions. It makes much more sense
