I want to know 2 things

1) Kindly suggest a power supply adapter suitable for Vigi C440-w security camera with voltage and amperage rating while keeping into consideration that the length of the power cable upto the camera is about 5 m.

2) Rest of my vigi cameras support POE so i connected all of those that way. 

Can i use TP-Link's POE splitter (https://www.tp-link.com/us/business-networking/accessory/tl-poe10r/) to power vigi-c440-w camera. The switch that i use is TP-Link's model TL-SG1008p (https://www.tp-link.com/in/business-networking/unmanaged-switch/tl-sg1008p/) which is an 8 port switch with 4 port POE and is 802.3 af/at compliant.
