Is anyone running into situations where the combined use of analog cameras/DVR with one or two IP cameras is a requirement. Perhaps the use a megapixel camera or the fact that a wireless IP bridge between two building is necessary, making IP cameras more practical at the remote building/site(s)? The montoring software for DVR would also manage/view the IP cameras.

Thanks

On occasion, yes. In fact our higher-end embedded dvr line offers an analog-dvr/ip specific solution. Unit records up to 4 analog / 12 ip (specific to same manufacturer's ip product). Software multiviews 100 dvr’s (max 16 on a screen at once). Choices on the ip side - very basic indoor fixed-focal-length ip camera or one-channel or six-channel video server coupled with any fixed or ptz analog camera(s). In higher-end applications though 3+ on the IP side may favor a second dvr (wired or wireless ip) if they’re relatively grouped (higher recording ips that is not network dependent, more storage, and ultimately cheaper) with seemless multiview with the other dvr(s) using client software. Not good for megapixel though – dvr at 720x would make it a waste (and don't know of any embedded analog/ip that would support that – would probably need to go PC Based or NVR and all ip). Also where analog are recorded at 60ips/4... ip are limited to about 5ips recording and of course ip recording is totally network dependent. Did solve a real neat municipality application with system where our dealer delivered 30ips recording of local esprit ptz's (using dvr) with 5ips offsite back-up of same camera (x6 sites) recording (using servers to 4TB remote back-up and control location - - was cool - they could even use Pelco keyboard at back-up / control center to joystick control remote PTZ's). Usually makes the most sense where you may have a single remote camera (like a guard shack) and often with a wireless network connection serving the ip camera(s). Seems like an especially good fit when you have a handful of critical (local embedded analog recording) cameras coupled with a number of others that are maybe less critical and spread all over (but have local power) where, for example an alternative of trenching makes a lot of servers, analog cameras, and maybe even wireless equipment a great deal.

KrCCTV- thanks for your response. It seems I'm running into more of these situations as you discribed. We have a harbor authority here who wants coverage around the marina. Hardwired cabling is not an option. So an IP based solution is key...

We have done several Hybrid based installs, now, they are quite usefull indeed, there are obvoiusly several ways to do it.

 

The advantages are quite unique, we recently did a establishment (pub) that also had a Motor inn accros the road, so we installed 28 Analogue cameras in the PUB and Bottle shop and put in 3 Ip based cameras in the Motor in, the system then streams to the Hybrid DVR without the need of cables, one of the best parts was that the Motor Inn receptionist can now sit at her apartment within the Motel rather than manning the reception after hours, we included a Decoder that was used with the the other stream from the Encoder, this allowed us to link the encoder to stream to the decoder in her apartment whenever somene pressed the buzzer, this meant that whenever someone pressed the buzzer she would hear a noise from the decoder and when she did that she only needed to to switch her television to the AV channel to watch the live decoded video.

 

It also meant we did not have to cable accross the road.

 

Another application was a Hybrid machine at an airadrome, the encoders supported Pelco Protocol so we were able to havea wireless network that could control the PTZ without having to run wires to the actual camera at al, it also meant we could record in high quality but transmit back to the encoder in lower quality, this meant that the moving pictures from fast moving PTZ's were more responsive and there was less latency with the keyboard controls.

 

They were very impressed that they could use the same keyboard!

Design them all day long and then some!!!!
