CAMSWITCH 4 PLUS VCS-4P1 POE Switch
- CCTV Lens Guide
- Hard Drive Size Guide
Unless selecting a vari-focal camera (with an adjustable lens) It is important to select the correct camera lens option for where the camera is to be positioned. A smaller lens will give you a wider angle but will be "zoomed out more", while a bigger lens will narrow the angle down and "zoom in more". See below to give you some idea on angles of Megapixel HD Cameras:
| Lens in mm | Approx Viewing Angle (degrees) | Ideal Distance (metres) | Typical usage/notes |
|---|---|---|---|
| 2.8 | 106 | <6 | For seeing as much of the immediate area as possible such as above a doorway/low down/garage soffits (edges can appear slightly warped/distorted) - clearly "zoomed out" |
| 3.6/4 | 83-90 | <12 | A great general purpose option giving great coverage still in the corner of a room or higher up on second floor soffits with less distortion - more of a natural "zoom" |
| 6 | 56 | 6-20 | Narrows down the angle and zooms in to look past the immediate area a little to gain more detail - down a driveway for example from higher up |
| 12 | 24 | 20+ | Zooms in significantly more to look at a gate, entrance or adjascent building |
| 16 | 19 | 24+ | As above but more so |
The amount of hard drive space you require is dictated by how many cameras, as well as their resolution and frame rate settings. Finally you can often make your storage space last a lot longer by enabling motion detected recording rather than continuous, especially if there are long periods of no activity.

Resolution (Megapixels) |
Days of storage provided by 1TB per camera (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (50% motion- 15 frames per second) |
|---|---|---|---|
| 1 | 44 | 11 | 36 |
| 2 | 22 | 5 | 18 |
| 3 | 17 | 4 | 14 |
| 4 | 11 | 3 | 9 |
| 5 | 9 | 2 | 8 |
| 6 | 8 | 2 | 6 |
| 8 (4K) | 5 | 1 | 4 |
| 12 | 4 | 0.5 | 3 |
As a rule of thumb we recommend a minimum of 2 Terabytes per 4 x 2-4MP HD cameras, as this should give you 2 weeks to a month with a few adjustments on motion detected recording. You may only require the full 25 frames per second on certain cameras if things are fast moving.

CAMSWITCH Plus network switches are 803.af/at Power over Ethernet (POE) 10/100 switches designed especially to meet the challenges of IP video installation. An optional POE input enables remote positioning and range extension, or a local power supply can be specified for maximum power budget.
CAMSWITCH 4 Plus features 4 802.3at POE ports, and a 5th port for downlink.
802.3at POE Power
CAMSWITCH Plus can deliver up to the full 25.5 watts required by IEEE 802.3at POE Plus devices such as outdoor or PTZ cameras. A selection of power supply options are available to suit the total power requirements and placement considerations of the installation.
CAMSWITCH Plus can be powered by POE, doubling the distance to connected devices or enabling network connections to be easily added to existing installations. Up to 25 watts budget at 200 metres is available using Veracity's OUTSOURCE Plus injector.
When a 57V power supply is used, CAMSWITCH Plus can deliver enhanced POE to Veracity OUTREACH Max, HIGHWIRE PowerStar and LONGSPAN products for maximum range.
Designed for installers
Camswitch Plus's network ports configure automatically for speed, duplex and crossover, and deliver 802.3af/at POE to compliant devices with no user setup required.
Snap-on clips are provided for secure wall mounting, and up to 4 units can be mounted in an optional 1U rack bracket.
