what Ip cameras are you guys using for this
Here I am using Grandstream and Grandstream OS cams and DIY's with Grandstream OS boards / Speco Domes and Grandstream decoder/encoder with Omnitouch 5.7e's and Omnitouch 5.7's configured with the HAI Video Hub, PCA, ZM NVR and IP cams. Legacy analog are Optex combos (still in place). Configured to talk to both analog and HD IP.
Its just what I settled on. Personal choice. Call up Leviton / HAI and ask them what they suggest for the "sure bet".
It is a bit of a race of providing the most features at reasonable prices and its hard to keep up.
IE: Megapixel resolution is now just about settling at 5MP or < $200 USD generic IP HD cams, POE is standard, variable lens stuff is standard, CPU / memory is faster and more, built in SIP, SD card slot recording memory, video alarm analytics (getting better; not soup yet), etc. Competition is tight. I mean the older companies do provide good quality stuff. Prices are up there though and the techology becomes absolute within months now making it hard to keep up.
Integration into the HAI touchscreens; old (Omnitouch 5.7/5.7e) is very much antiquated still. It works. The PCA configuration will work with just about any current standard of IP cameras. Note that it is throttled down a bit with a choice of two resolutions and no 30 FPS streaming.
Even new stuff without enough GPU / CPU power is going to have a hard time multithreading 30 FPS HD IP streams. Add up the numbers; its just basic math stuff.
