Why NVR?

Why not use a 2+mp TVI system? Why bog the network down with individual camera traffic? I find there's far less issues with TVI systems, better camera aesthetics and options, less network congestion, limited network configuration, easy retrofit, and IMO better picture quality.

Also, if you use the right system, you can have auto NAT, and essentially auto port forwarding via UPNP settings. No DDNS, and little worry when a router/modem gets swapped out.

That is a good question. Why should I use IP cameras? All I can think of is the ease of terminating a Cat cable compared to coax and power.

Why use UHD Bluray when you can just use VHS?
Why use HDMI when you can just use S video?
Why terminate 2 wires when you can juse do 1?
;)
Can you do 8mp with TVI?

You can still use cat, just get some HD baluns with pig tails used for CCTV.

This isn't the TSA. Its a restaurant that needs a 6 dome system for under $2k.

jesterselv,
All the points you made have nothing to do with the technology (TVI vs. IP), but about the brand you are using. Everything you said about your TVI brand you are using, is the exact same with a similar IP systems:
Camera choices, auto NAT, etc. have nothing to do with the camera technology.

As far as network traffic goes, most of the Hikvision OEM IP systems have built-in switches with POE and auto VLAN. You simply plug & play (like you would on a TVI system) and you are done - and no IP traffic on the main LAN. Plus do not have to mess with the separate power supply of coax cameras.
It is only when you go above 16 IP cameras, that you have to do your own POE switch and configure it.

IP camera systems have several advantages over coax however. Higher resolution cameras for one. You can have clusters of cameras on a building, then send it over to another location with just one cable. And fiber between buildings (or remote locations like a gate) is a lot easier than all the black boxes you would need with coax based systems.

Coax based systems ONLY have 2 advantages. Price for those entry level systems. And when upgrading a system that only has coax w/power to each location.

Do they have access control in the building?
GeoVision uses their cameras for integration of access control.
Cameras are not bad or cheap, so if they're trying to upgrade, be sure to understand what they have now and why they're unhappy.
Last thing you need is to install new system only to see disappointment on client's face.

As for IP being better -- it can be, but it isn't necessarily by default.
It can be a bit laggy due to encoding.
IPOD cameras can go up to higher megapixels, but if you're asking for 2MP, IP has no advantage.
IP does cost more due to onboard processing.
Terminating Siamese cable is easier than RJ45 -- learn how to do it.
