Question: Could I use 4 analog and 2 IP cams with this at the same time?
Document: That's it for hybrid mode and you should note that you can't do 960H analog and IP cams at the same time.IP MIXED MODE:Choice #1: 1 IP cam at 720P, PLUS 7 IP cams at D1, up to 8 playbackChoice #2: 1 IP cam at 1080P, PLUS 1 IP cam at 720P, PLUS 2 IP cams at D1, up to 4 playback**THE GOOD**+ Seems to be stable in testing so far.
IP cams generally require more processor time so for 1080P/720P cameras there are limits on how many you can connect to. Example, you can only connect up to 4 720P IP cameras, or 2 1080P IP cams.
The summary of all of this is that if you what to use Onvif cams and have them generate their own OSD timestamp then they will ALL need internet access and need to be configured to use a internet time server.- A big flaw for me is that I wanted to connect some 960H analog cams and one or two 720P IP cams.
The second way is to sync each cam to the DVR via Onvif time sync, which this DVR has an option for, except it DOESN'T work! I have tried this with a few different Onvif compatible cams and have not been able to get it to work with any of them. If the DVR could act as a NTP server mode so that the cams could sync to it then I would use option 1 and sync cams to the DVR.
Also the video decoder chip gets pretty hot during operation and I feel it should have a passive heatsink on it.- Unlike other DVRs there are no alarm input or relay output for connecting things like door alarm switches to the DVR. While most people would not use these features they can come in handy.- While there are 8 analog video inputs there are only 4 audio inputs.
While I can connect to the cams and view/record the picture, note that digital (Onvif) cams do not have the DVR's time/date stamp overlay (OSD) recorded with the video (as done with analog cams). This means that the only way to get a timestamp on the recorded video is to have each camera generate the OSD display. This means each cam must be able to set its own clock so that the video timestamp is accurate.
I am experienced with DVRs and analog/IP security cameras and have used many DVRs. I like this MT-HDVR3308T 8 channel DVR as it supports 960H analog cameras (960H cams are capable of a better resolution image than older analog cams) or alternately IP cams (or even both D1 analog & IP cams in hybrid mode).
*DVR MODES*This DVR can function as an analog-only DVR (connect up to 8 analog cameras, including 960H cameras), an IP camera only mode (connect varied # of IP cams depending on resolution), or a Hybrid analog+IP cams mode.
I have tried a few IP cams that claim ONVIF compatibility but were not detected with this DVR's ONVIF search. One high-resolution outdoor day/night IP camera that did work wasGrandStream HD Mega Pixel IP Camera with Networking Cameras.
If you are using PoE (Power over Ethernet) cameras you will need a PoE Switch if you want to power the cam this way.- The DVR infrared remote does not come with batteries. You will need 2 AAAs.OVERALL, it seems to be a functional DVR for the price, especially with analog cameras.
Answer: Yes , but I found it dificult to find the right camera to work on the unit. So I gave up on the IP and went to analog. I found analog more reliable.
