DVR-N4 4 channel digital video + 2 channels audio recorder (DVR) with network remote viewing ability & built-in
dedicated operating system (non-PC OS). This unit is 'plug & play' compatible with ALL of our cameras and

BNC video inputs). Top quality 7200RPM HDD with 8MB buffer included INSTALLED (250 GB) + expandable to
additional storage/ drives by request.

Profile:

What a great digital video recorder! More features with MUCH higher quality + speed in comparison to similar
looking DVRS, many of which are terribly slow on playback with poor quality video. With any of our cameras and
plugged into any simple RCA capable television, this is ready to go within minutes of opening box (though there
are many advanced features which may take hours to learn about and test, etc.).

• Internal video motion detection function converts ANY camera into a MOTION DETECTION camera. Records
ONLY when activity is present in the frame.

• Jog shuttle feature allows quick forward/ reverse scanning through video archives

This DVR has what most prospective purchasers of a 4 camera system would want: super fast playback speed on
every channel, very good visual resolution on play back of recorded video, dynamic motion detect recording
ability and even 'full-frame' + digital zoom ability on playback of any channel. This is a GREAT value for any small
multiple camera operation.

Many consumers are often BLINDED by buzzwords and end up putting far too much emphasis on the numeric
technical specifications. NUMBERS on PAPER in the electronics industry (including video) often don't even get
CLOSE to an accurate representation of what end-quality performance and satisfaction the user will experience.
These numbers almost NEVER give any consideration to the level of engineering and manufacturing for the
particular device. Too many in our industry are advertising their DVR systems with spec numbers and buzzwords,
often with no regard or concern about what level of practical quality technology exists. And please BEWARE the
claims of what "PC" slot recording cards will do for you.

DVR-N4 1

Super fast playback is visually nearly real time for any channel, even when all channels are recording at once.
Most which spec like this have a visible slow drag in time on playback of the compressed video. This DVR 'specs'
at 60 FPS / frames per second (not 'fields per second' as is so often misrepresented in this industry). On paper,
60FPS shared between 4 cameras is 1/2 real time, considering that 30 FPS per channel is judged as real time
video (even though with PAL video it's actually 25 fps). So, for 4 cameras (or channels of video), 120 FPS
(30FPS each x 4 = 120) is considered true "realtime" speed of video. Please see our DVR-RT4 for full realtime
spec capability (at high resolution for each channel).s

*The #DVR-N4 is one of those rare devices because it EXCEEDS its own technical manufacturer specifications.
It appears to have much closer to 100+ fps record / playback speed! Almost not a single 'drag' in any of the
video recorded from 4 color cameras with simultaneous activity in all fields (only true test is to maximize
bandwidth requirements when recording).

Very good quality in playback. Not true 'high resolution' recording as in our professional real time #DVR-RT4 ,
#DVR-RT8 and #DVR-RT16, but WAY better than other such units which spec at 320 x 240 lines per channel
(and advertise at '480' based on a number for VIEWING-ONLY of one SINGLE CHANNEL ONLY having
NOTHING to do with the recording!). BEWARE, we have seen some that were so poor in image quality that we
didn't know whether to laugh or cry (since we had already purchased it for sample evaluation purposes).

The internal motion detection ability of this unit is AMAZING! Highly adjustable and extremely sensitive when
desired. Also includes the ability to 'mask' out certain areas in which user does not want motion to activate
recording (such as passing cars on a street, etc.). Many DVR systems have (although many still don't) this
internal ability but each major OEM seems to have its own unique method. We've tested several which looked
'antique' in relative comparison to the dynamic control and ability to adjust sensitivity on this one- it's GREAT.

This is considered a 'standalone' unit as it does NOT require any type of computer, though it CAN BE
NETWORKED through its rear LAN port connection (RJ-45 type plug) to a PC computer for remote access
viewing from multiple computers and/ or even over the internet (CD software included). PC remote viewing only.

We carry ONLY proven, stable video recording technology and even the very best hard drives are installed. We
special order and install only 7200 RPM HDD drives with 8MB buffer by Western Digital®, Seagate® and
Maxtor®. Do you really know what you're getting in your DVR if it isn't from CD3?! Likely a generic brand low
capacity HDD with no buffer- and often even only too slow 5400 RPM performance!

Common Applications:

• Residential and small business security solutions

• Remote video monitoring of vacation property, etc.

Available Options:

Handheld wireless IR remote control included FREE with each DVR-N4 ordered.

FREE bonus accessory package includes RCA-BNC video plug adapters, remote viewing software CD and more.

We can install a second HDD (hard disk drive) to increase storage capacity to 500GB. Simply tell operator you
want DVR-N4 and additional HDD-250.

Variations / Alternate Equipment to Consider:

For the ultimate in versatility and performance, consider our PROFESSIONAL HIGH RESOLUTION REAL TIME
DVR SERIES #DVR-RT4, #DVR-RT8, #DVR-RT16. Like the DVR-N4 and DVR-N16, these are standalone (non­PC based) but still networkable systems. However, our realtime units feature one channel of audio PER every one
channel of video and the 4 and 8 camera models are high resolution 480+ TV lines PER channel (each camera).

Our DVR-N16 is the 'big brother' of this unit. They are physically identical but they DVR-N16 has the ability to
handle 16 channels of video + 2 channels of audio.

Cautions:

Networking this recorder into a PC computer system could potentially be confusing for some. And, unfortunately­based on type of computer, operating system and how particular settings are configured- there are simply too
many variables involved for us to provide any kind of 'easy advice'. Generally speaking, if a customer has read all
included instructions but still has trouble setting up a camera, wireless unit or VCR/DVR, we will be happy to walk
the person through it over the telephone. However, networking issues are where we must 'draw the line', since
they are generally far too complex and time consuming for our technicians to convey sight unseen over the
telephone.

This unit is NOT designed for mobile or vehicle applications.
