I am planning to install a small CCTV network of about 4 PTZ POE TP link cameras. I dont want to use a NVR buti I want to be able to access onboard SD cards and operate PTZ using the TP App. I have a 6 port POE switch and a TP Link RE450 wifi extender. The POE switch and RE450 will be sited in the loft where I have Wifi Signal but unable to run a CAT5 cable to my router.

 I plan on connecting  the RE450 to the POE switch by cable. I am unsure how I should configure the RE450 either as a bridge or access point. I have read that as a bridge latency can be as much as 10Sec as this would be unaceptable.

Suggestions for a solution would be appreciated.
