I need to understand the ease or difficulty and cost of utilizing either: - a multichannel analog to IP encoder OR - getting TVI/CVI/AHD/etc. DVR that can output EACH channel as IP stream in full 2-6MP, that I can then feed into the Dahua NVR DHI-NVR6A08-128-4KS2. Background: I had over 40 cameras in my own project that were all wired with both siamese and Cat5e over 15 years ago. At that time analog was installed in all locations utilizing siamese cable. Cat5e was run for possible CTRL/PTZ, etc) and left dark. Few months ago, with dying analog cameras and DVR, I made a decision to switch to IP. I bought 128Ch Dahua NVR DHI-NVR6A08-128-4KS2 and started slowly replacing analog for IP using the Cat5e. I ran into one location that only had siamese -- huh? I guess one of my guys forgot to run it. "No problem"; I though. I purchased $125 IP/PoE over coax solution which will let me install the IP camera using only coax. That installation completed sometime next week. Today I found another location that apparently only have siamese. That's no bueno. I can't be spending as much on the convertor as I do on the camera. I'm now wondering how many other locations I have that do NOT have Cat5 wires in the wall? I'm thinking that if I can get 8 or 16 channel analogHD DVR -- no harddrive needed, I can get me some quality cameras and encode them (thru DVR) to output IP stream into the IP NVR. That way I have a single source to display on TVs, monitors and automation controller. P.S. Yes, I did look at hybrid solutions, but none of them offered enough channels AND ability to do 12MP feeds.

Are there any NVRs out there that allow the string based ( IP, Serial, Alarm In) input to change the HDMI's view? Lets say that I have 32 channel NVR. I'm watching all 32 channels on my TV (distributed HDMI feed to all house TVs). Now, let's say that the UPS guy rings the gate intercom. My automation software opens the gate, turns on the lights (if dark), starts playing music in the driveway and foyer. I would like to be able to trigger a command that would change the HDMI's display from the 32 channels (or whatever it's on) to a 4 camera view, AND display cameras, 1,9,20&32 in that order. After a minute, automation software would send another command to return to the 32 channel view. Also, let's say that we're having a party. I would like to invoke a 9 channel view with cameras 7,1,4,16,22,x,x,x,x. The point is NOT to just arrange the cameras in a specific order and then change from 1,4,9,16,20,25,32 views and possibly having to flip to 2nd or 3rd page (sequence). I need to be able to specify the # of cameras AND the order of them. I could have sworn that I saw something like that where the string looked something like this: 192.168.1.101,16,6,2,8,3,4,x,y,z,etc. where the IP was first, then the number of channels to be viewed (16 in this example) followed by specific cameras in order from the top left.

Over the years I've acquired/purchased several analog cameras. Right now I have 30+ analog cameras, some Dahua 4.3MP ones, as well as few of the 12MP pucks. I also have several of the HikVision IP cameras. I have 2 of the 16 channel IC Realtime analog DVRs, 2x HikVision 8CH IP NVRs, as well as a smaller 4 channel Luma NVR. I'm trying to unify everything into a single, recorded and easily viewable (thru HDMI) interface. I'm wondering if there is an analog DVR that would accept BNC inputs and output IP streams that I can then feed (LAN) into a 64 or 128 Channel NVR. Or, is the analog-to-IP encoder still a way to go? During one of the Expo shows I've attended, sales pukes talked about being able to have multiple recording devices that would pass the streams among themselves due to geographical layouts. The idea was to have several, local cameras feed local NVRs or DVRs that would then over LAN connect to the main hub (master NVR) which would then spit out all the channels on a single HDMI output (monitor, TV, PJ, what have you). Of cause, as soon as I started asking details, the sales pukes didn't have the answers and while promising to get back to me, never actually did. Any info and details on this will be greatly appreciated.

Guys, I searched and searched but couldn't find anything relative so here it goes: I have a client that has a gate .5miles from main building. He has some cheap crap for transmitter that only lasted 2 seasons but it was only few hundred bucks. There is no fricken way to trench from gate to building. I know I could go the route of IP and do a bridge, but he's set on using his current analog CCTV setup, for both cameras and DVR. What have you used that worked well for you for 1/2 miles more or less line of sight, where the only obstacles may be few tree tops. I would rather use one device that can do 2 cameras, than two separate ones, but if that's not an option then so be it. Range or interference should not be an issue as he was able to use some few hundred dollar crap that worked until it didn't. He suspects that it failed due to weather. I didn't install the original equipment, and have already asked the client to give me model number for the current unit. As soon as I know what he has, I'll update this post. TIA Mario

Thanks, that's what I was afraid of.

This past Monday, we were asked to review footage from DVR system we installed to see if we could help authorities with identifying perp from residential burglary across the street. The one camera that was set to record on motion, did captures several vehicles driving on the street, it even recorded the homeowner backing out of his driveway at night (0555), but failed to capture the whole sequence of perp driving into same driveway (as H.O. that left that AM), the perps walking out of the car (OK, that was small motion to detect), and 4 minutes later, car pulling out of driveway and driving away. Another camera (very bad angle and point of view) that was set to record continually during day hours caught the whole thing (obviously) but couldn't get any detail. We've since increased the motion sensitivity of the DVR, but won't relay on it as an alarm detection point. Mario
