  1. Hello all, Does anyone know of or have any recommedations for a PoE switch that has a watchdog/ping feature built into it so that it can ping a device (camera) plugged into a port and, when it becomes unresponsive, automatically power cycle that port? I found this at ISC West when wondering around but it's a bit pricey compared to the managed switches we've been using: http://www.transition.com/TransitionNetworks/Products2/Family.aspx?Name=SM24TAT4XA&ProductID=666668 http://www.transition.com/TransitionNetworks/Uploads/Literature/Auto-Power-Reset.pdf I know the Ubiquiti Touch Switches support this but the one-year limited warranty is kind of a deal breaker. Regards!
  2. Have at look at http://www.razberi.net/ Thanks for the link! I've only given this a cursory glance but the switches/embedded NVRs look promising. I remember seeing something about the Razberi being sold under other names, too. Anyone know what those are and how they differ from a software perspective (i.e. are they still running Milestone Acrus)?
  3. Yes, sir! Without proper documentation we would be screwed.
  4. For sure, it's rarely that simple. I was just trying to get an idea about what other people typically do to tackle these problems in order to prevent truck rolls and keep the systems running and customers happy. We usually end up using managed switches and some VNC to remotely access the network so that specific cameras can be power cycled but that means putting more expensive switches in place and requires access to the PC based NVR or a customer's computer on the network. I haven't found an embedded NVR with built-in PoE that allows individual PoE ports to be power cycled (if anyone knows of one, I'd love to hear). This can be cost prohibitive for some customers that can't afford a PC based NVR or the managed switches.

    Multi Channel Over Single Coax?

    No one has any experience with any devices like these?
  6. Hello all! I don't know if this is the correct subforum for this question. If not, maybe a mod can move it over. I just wanted to take a quick survey and find out how CCTV/IT professionals deal with unresponsive IP cameras. Assuming that the cameras are powered via PoE switch or some sort of PSU that's plugged into a networked remote power manager (RPM), how do you go about dealing with this issue? I know sometimes cameras just glitch or are no longer responsive over the network and require a power cycle. Of course, mitigating the causes of these glitches is most important. But, assuming all things equal and a camera just needs to be power cycled to fix the dropped connection, what do you usually do? Thanks for your time!

    Multi Channel Over Single Coax?

    Hey all, New poster here. Been reading through the forums for a while and really appreciate all of the wonderful information. Question: Anyone every use anything like this to get multiple cctv channels over a single coax cable (TVI or other analog)? http://hnhmcy.en.alibaba.com/product/60216873336-210595947/4_Channel_Multiplexer_CCTV_Video_RS485_Transmitter_RG59_Coaxial_MUX_Modulator.html?spm=a2700.7803228.1998738836.12.DdA5tb OR http://www.alibaba.com/product-detail/1080p-multiplexer-4-CHANNEL-TVI-CVI_60399233216.html?spm=a2700.7724838.30.88.d0i35W OR http://www.alibaba.com/product-detail/4-Channel-Video-Multiplexer-for-1_60271199148.html I'm not asking if anyone has used these specifically but whether anyone has used something similar with success that might not require ordering in bulk from China. Why TVI and coax as opposed to IP and fiber, you may ask? We have several accounts with housing authorities with duplex housing setups. Aerial runs of RG6 with messenger were placed with PTZs. The PTZs are missing a lot of action due to tours and we would like to replace them with fixed, varifocal cameras without having to run more aerial cable. The budget is quite low for these accounts. The closest I've come to devices like these state side (I'm in the US) are products from Jayso Electronics: http://jayso.com/collections/cctv-multiple-camera-over-single-coax but they neither support RS485 nor TVI and are quite expensive individually. Any help is greatly appreciated! Regards, Ryan
