TechTurkey 0 Posted October 17, 2013 I am pondering which setup would be the most cost-effective and reliable: The building is 8 stories high, rather narrow structure. It has an existing DigiMux DG4016 BNC vid/wired power/included CRT monitor (a pretty dated system, but working), I found the documentation, but cannot find if it's a 12v or 24v system. There are 10 in-place cameras, no PTZs, just night vision and some are zoom capable, possibly 400TVLs. 2 cameras in the carport area will need to be replaced due to theft. I need to add 10 more cameras. 7 cameras, starting on floor two across from each elevator door. 1 on floor eight by outside roof access, 1 more in dead area by front lobby and 1 viewing parking gates. That is a total of 22 cameras, 12 are existing (minus the 2 already wired, theft replacements) and 10 at new locations. I would love to install a 2.4ghz (5ghz doesn't do well through walls) wireless system for video and power them at each camera's location. It would be just under 1000ft of cabling otherwise. Longest run being ~150 foot. So here are my questions to you: Should I replace old DigiMux and use existing cabling? 22 total cameras falls into purchasing new 8 camera system and also a 16 system to cover the 22. Keep the DigiMux, utilize it's 4 unused BNC ports (16) and just purchase a single 8 camera system and have 2 extra ports (or use just 2 from DigiMux and all 8 on new sytem, doesn't matter much)? How well is the RG59 18/2 Siamese cable shielding for interference? Do I need to use EMT conduit? What are the run length limits and will RG59 22/2 suffice? Is it possible, cost effective and just as reliable to do a wireless system? Labor alone really adds up, if I were to run lines. What products would be super spiffy? I have done several larger home installs, all cabled 8 camera systems, but this is not my true trade. I know the building owner personally and he is curious what MY bid would come out to.

TechTurkey 0 Posted October 17, 2013 Come to think of it, my first install was a cat5 Samsung SDE-4001N. So there's another option using a cat5 system. Share this post Link to post Share on other sites
adamxp12 0 Posted October 19, 2013 rg59 is usually shielded and i have run all my cameras with it (no problems with interference) because i could not be bothered with cat5 you should not bother with cat5 either it has a lot of interference and adds more bulk with baluns rg59 can go up to 1000ft never tried more than that Dont bother with wireless it is insecure someone can view your cameras with a cheap baby monitor or a wireless cam sniffer I would replace the digimux because its from 2003 so the image and fps is probably not so good Share this post Link to post Share on other sites
TechTurkey 0 Posted October 20, 2013 Thank you for your insight adamxp12. It was stuck in my head, that using a hybrid NVR and utilizing the existing BNC cabling/cameras and running cat5 IP cameras for the new runs would've been easier. If I were to purchase a 24CH Dahua DH-DVR2404HF-S would the existing cameras, due to their age, be incompatible? I've read that the ONVIF 2.0 protocol cannot use motion detection function unless all cameras are Dahua. Or is that just for IP cameras? I've searched around for the DH-DVR2404HF-S, but seems only the 32CH model is available. Share this post Link to post Share on other sites

The old cameras should work fine as long as they have a standard bnc connection ONVIF is a ip camera standard so yes the analog cameras will work fine with motion detection if the dahua has it Share this post Link to post Share on other sites
Kawboy12R 0 Posted October 20, 2013 Running analog cams on an analog wireless system will be a nightmare. Lousy video quality with interference making motion detection worthless. Microwaves, cordless phones, and lots of other things can wipe out or seriously degrade your signal when running. Run the wire. You don't want to be the low bid because everybody else knew that the cheap way out wasn't worth it. ONVIF is for IP cameras. If the owner can live with reviewing two systems for footage and has the room, look into running the analogs on one system and some IP cams on another. It's more flexible than finding a hybrid system that does everything you want but has the disadvantage of having two systems to learn and maintain. Share this post Link to post Share on other sites
TechTurkey 0 Posted October 20, 2013 Thanks guys! Any info if the Dahua DH-DVR2404HF-S is purchasable here in the US? I'm in California. I found a couple that look like older models. Share this post Link to post Share on other sites
TechTurkey 0 Posted October 20, 2013 Are the BNC-Twist-On Connectors junk? Stick with BNC Crimp-On or Compression Connectors? Share this post Link to post Share on other sites
adamxp12 0 Posted October 20, 2013 Are the BNC-Twist-On Connectors junk? Stick with BNC Crimp-On or Compression Connectors? I have used twist on connectors in my home system with 15 camera and they are fine but the crimp and compression connectors are better but also more expensive No difference in quality it's your option Me personaly would use twist on because they are simple and require no tooling Share this post Link to post Share on other sites
SectorSecurity 0 Posted November 1, 2013 Stay away from the wireless in an apartment there is likely to be many wireless routers all broadcasting junk, cluttering the channels. I don't know why everyone hates on CAT5 cabling, I love using it, but thats just me. Do you know what kind of shape the existing cables are in? Share this post Link to post Share on other sites
