Would this equipment list be suitable for the job?

Hi

We are a small business and require 2 IP cameras to monitor the entrance and car park. They need to be able to record on motion 7 days a week day & night. We have a limited budget but would like to be able to view the cameras remotely, a mobile app would be a bonus, record on motion and store the videos on our server for a rolling 2 week period.

I have chosen the below cameras after weighing up price/performace: (Hikvision DS-2CD2032-I 3MP IR Mini Bullet Camera)

Software wise I've been looking at Sighthound for $60 as it seems to tick all the boxes:

Finally we will need some PoE injectors as our network switch isn't power over internet compatible, I was thinking of using something like below and just using the injector part as we won't need the splitter.

We will then need some cabling to connect everything together, will just normal cat5e ethernet cable work rated for outdoor use:

I would appreciate any comments on this setup, it is budget and comes in at around £250 / $400 for everything.

Thanks

Anyone?
