Stick up cam Elite has "poor connection" over PoE -- how?

I am using this switch for my house:

BV-Tech 18 Port PoE+ Switch (16 PoE+ Ports | 2 Gigabit Ethernet uplink) - 130W - 802.3at- POE-SW1602A https://www.amazon.ca/dp/B01MQHD54L/ref=cm_sw_r_cp_api_i_nccaEbDDV2MFT

I doubt it’s the speed. But I will test shortly.
