are you using WIFI cameras or are they hardwired to the network via Ethernet cables.
Does the video traffic run through the router ?
What is the FPS and Iframe values on the 5 cameras.
What are you running ISPY on ?

Wifi Cameras yes it goes through the router. frame rate is sporadic it goes from 10 to 1.5 and back you 10. windows 10 . SPEED TEST IS 24 MBS OUT OF 25 MBS. and I can not get the sound to come out on Ispy. it shows its picking up sound but not playing sound on Ispy

you have the wifi network overloaded.
============================
I have posted this before.
I did a wifi test a while back with multiple 2MP cameras each camera was set to VBR, 15 FPS, 15 Iframe, 3072kbs, h.264. Using a wifi analyzer I selected the least busy channel (1,6,11) on the 2.4 GHZ band and set up a separate SSID and access point. With 3 cameras in direct line of sight of the AP about 25 feet away I was able to maintain a reasonable stable network with only intermittent signal drops from the cameras. Added a 4th camera and the network became totally unstable. Also add a lot of motion to the 3 cameras caused some more network instability. More data more instability.
The cameras are nearly continuously transmitting. So any lost packet causes a retry, which cause more traffic, which causes more lost packets.
Wifi does not have a flow control, or a token to transmit. So you devices transmit any time they want, more devices more collisions.
The problem is like standing in a room, with multiple people talking to you at the same time about different subjects. You need to answer each person or they repeat the question.
As a side note, it is very easy to jam a wifi network. Wifi is find for watching the bird feed but not for home surveillance and security.
For a 802.11G 2.4 GHZ wifi network the Theoretical Speed is 54Mbps (6.7MBs) real word speed is nearer to 10-29Mbps (1.25-3.6 MBs) for a single channel
