HI I am in the market for a 8 or 9 channel CCTV DVR (digital video
recorder.)

I have 700 TVL cameras so they require a recording resolution of D1 or
4CIF (both are very similar if not identical)

The attributes that the DVR *MUST* have is a full recording capability
of 25 fps at full D1/4CIF on *ALL* its channels simultaneously.

so thats a global recording resource of 200 fps at D1/4CIF for a 8 ch
unit and 225 fps at full D1/4CIF for a 9 channel unit.

It is required to work with android smartphones, iphones and ipads so
that also means the DVR must be connectable to the internet.

I do no need PTZ controls.

Support for HDMI output.

I do need Motion detection.

Support for a DVD burnerwould be nice as well as USB and internal hard
drives would be nice

Pentaplex support is also required, that is, live, record, playback,
backup & stream simultaneously.

video loop through is also desired so I can feed the cameras into a bank
of RF modulators so that the live pictures can then be viewed on all TV
sets in the house.

Any recommendations for a bullet proof & robust make and model of DVR
that does not break the bank.

I've looked at the Swann 4200. That seems OK at the price point but has
no DVD burner or video loop through.

This is potentially not a deal breaker as I probably can take the 75 ohm
resistors out of the RF modulators.

So some recommendations on RF modulators that have switchable or
removable 75 ohm input impedance termination would be useful.

Whats peoples opinion of QVIS, Hikvision and Dahua?

I've had a look at Distributed Micros. Wading through their website
makes it hard to identify which specific model can support FULL D1/4CIF
recording across *ALL* channels simultaneously. They are expensive brand
new so second hand off ebay or Amazon seems to the only option if I want
a Distributed Micros DVR.


I use this one:
http://www.cameras-cctv.com/DVR_8-9_...DVR-8CH-RF2836
(the model has changed slightly since I bought mine a year ago, so you
would need to check what connections are currently fitted)

I've had good support from this firm, so can recommend them.

It records 8 cameras in D1 at 25fps each.
The network software works fine, either over a local LAN or remotely
on an Android phone.

My only complaint is that it does not have NTP time setting, so the
time stamping is not accurate. I have to reset it manually which is a
pain. Perhaps the later model has NTP.

N.B. It's cheaper to buy these recorders without an HD and add your
own.
