dvsystem 0 Posted May 13, 2014 Seems like a great deal for $500, I realize it's analog, should I still go for an NVR instead? http://www.costco.com/Q-See-8-Channel-720p-HD-Security-System-with-2TB-HDD-and-8-720p-Cameras.product.100104432.html Thanks Share this post Link to post Share on other sites
milkisbad 0 Posted May 16, 2014 wow at that price...looks like the dahua HD-CVI stuff, can't believe how cheap it is for 8 cameras. But if you want to future proof (and IP camera prices will go down), might as well get NVR now and have cat5e cable in place. Share this post Link to post Share on other sites
dvsystem 0 Posted May 17, 2014 It seems seems at this low price point for a full system, I could just go with a new NVR system in a couple of years and not really lose anything since its costs about the price of two decent cameras. It's still a tough decision to make since I really like the idea of cat 5 cams. Thanks Share this post Link to post Share on other sites
milkisbad 0 Posted May 17, 2014 2nd way is to not use the cables in the kit and run your own cat5e, then use Baluns. I heard HD-CVI will work with balun just like analog cameras... Baluns transform the 75 omh signals from the camera into 100 omh signals (which the Cat5 needs to transmit the video) then back to 75 omhs at the 2nd balun at the DVR side and feeds into the DVR, each camera needs 1 pair of balun. Where can you buy Balun and what does it look like?? http://www.amazon.com/PAIRS-Mini-Video-Balun-Price/dp/B007XUU6EA/ref=sr_1_2?ie=UTF8&qid=1400290157&sr=8-2&keywords=balun (one of the most popular style, but other style exists including some that can transmit power) just keep your positive and negatives in check and the color of the cat5 and you'll be set.

shockwave199 0 Posted May 17, 2014 Also keep in mind that 4 of those cameras are only indoor rated. For me CVI was a temptation but because I'd have to take down my premade cable anyway because it's not good enough, it makes more sense to just redo everything to networking when I'm ready.

Great catch, I've never seen indoor rated cameras included on a bundle, guess I'm out and will wait for an good NVR deal. Share this post Link to post Share on other sites

acmaster 0 Posted June 12, 2014 Does it really make sense to not just invest in an IP based system? That is a great deal but you will try and future proof which adds cost. Baluns add cost and eventually everything will be IP so spend a little more on an IP systems and be truly future proof. JS... Share this post Link to post Share on other sites
buellwinkle 0 Posted June 13, 2014 You can always use the old coax cables to pull new Ethernet, so I don't think it's a that big deal. If you are OK with 720P, these seem like a good deal if you need 4 indoor, 4 outdoor cameras. Just think of it like a closed system, if a camera dies you may not easily get a replacement or if you want a different camera, you may not be able to do it.
