Kollector FAQ
Q: What is the daily hard drive usage of a Kollector?
A: KOL3000 series, 4000 series and 8000 series will use about 1 GB a day
KOL9000 series will use about 3 GB a day
KOL7000 series will use about 10 GB a day
*Note these are basic averages that are directly affected by scene movement. Increased
movement will directly increase file sizes.
Q: Are there any controls to maximize the bandwidth on the Kollector Series device?
A: The LAN Master Software (LMSW) station sends a request to the networked Kollector and
establishes a dialog.
The amount of bandwidth used is dependant on:
a. The amount of information being transmitted
b. The available bandwidth of the network
All network devices will try to use the maximum bandwidth available. Since the networked
Kollector has a 10baseT card and there is no other traffic, then the available bandwidth is
10Mbps. However, data for 16 cameras from a KOL4000 to the LAN Master Software (LMSW)
station is usually between 1-3Mbps, so it only uses that much. A KOL7000 could use up to
10Mbps max. Very little bandwidth with no motion, no bandwidth if not connected.
Q: How does the Kollector talk to the LAN Master Software (LMSW) station when viewing? Does
each camera send video or do all active cameras get sent together?
A: Each window on the LAN Master Software (LMSW) station can be described as a channel.
Each channel transmits a packet of information, in a First In/First Out (FIFO) sequence.
Q: Is the Bandwidth between LAN Master Software (LMSW) station and the Kollector a function
of the number of video scenes being viewed at one time? If so what is the Bandwidth
requirements per video scene?
A: Yes. The bandwidth per channel (up to 24 video scenes per LAN Master Software (LMSW)
station) is variable based on change in scene. The compression medium we use records and
transmits changes in the scene. Zero change in the scene equals almost zero bandwidth.
Greater change in scene equals greater increase in bandwidth. This changes constantly
along each channel, many times per second. A good rule of thumb would be to say the LAN
Master Software (LMSW) station uses between 3-5Mbps when operating 24 channels. (2
Kollectors with various channel mix) This divides out to 0.21Mbps per channel if all the channels
are at greatest demand when used with a KOL4000 series unit.
Q: Does the KOL7000 series have any better through put (Bandwidth/ Frame Rates to the
remote clients on the network than the Kollector 4000 or KOL9000 series)? What would the
maximum monitoring refresh rate be on a moving object at max resolution?
A: The KOL7000 has 4 video inputs that each record at a 30fps. Remember that the required
bandwidth is dictated by amount of change between frames on each camera. So a KOL7000
series, having more frames per second, would use more bandwidth.
