Environmental


Surveillance cameras are often placed in environments that are very demanding. Failure to adequately protect an installed device from environmental factors can cause premature failure or void the product warranty.

It may seem obvious that a camera placed outdoors might require a specific housing, but it may also be required inside an industrial facility with a high amount of moisture or dust in the air. Assessing and understanding the environmental conditions prior to installation is essential for selecting the correct cameras, and prolonging their lifespan.


Select the correct housing based on conditions


Camera housings come in various sizes and qualities, and various features. Housings are made of either metal or plastic and can be classified into two general types: fixed camera housings and dome camera housings.

When selecting an enclosure, several things need to be considered, including:

  • Side or slide opening (for fixed camera housings)
  • Mounting accessories
  • Clear or smoked dome (for dome camera housings)
  • Cable management
  • Temperature and other ratings (consider the need for a heater, sunshield, fan and wipers)
  • Power supply (12 V, 24 V, 110 V, etc.)
  • Level of vandal resistance

For more information on housings, see the Axis Accessory Selector or the Product Accessory page.


Use the correct connector


The RJ-45 Push-pull Connector (IP66) which is shipped with the AXIS Q60-E and P55xx-E series of outdoor-ready PTZ dome cameras is required to be installed according to the instructions in the following document:
RJ-45 Push-Pull Connector Installation Guide

The customer can use the connector being shipped, or decide to order an optional premounted cable with the connector already attached, called the RJ-45 IP66-rated Cable with premounted connector (CAT6) 5 m. This connector maintains the the IP66 rating of the camera and prevents dust and moisture from entering into the dome assembly.

Ethernet cables can be run outdoors, but their thin plastic casing will deteriorate quickly when exposed to the elements. For best results, outdoor Ethernet cables should be placed in a conduit and buried a fair distance away from power lines or other sources of electrical interference. Remember to use an STP cable if the camera is used outdoors or if the network cable is routed outdoors.

PVC or other plastic pipe, installed with waterproofing, can work as a conduit. Special exterior or direct burial CATEGORY cables could be used for outdoor runs. Direct burial CAT5 cable costs more, but it is designed specifically for outdoor use. Both ordinary and direct burial CAT5 cables attract lighting strikes to some degree. Simply burying a cable underground does not lessen its affinity for lightning. Accordingly, CAT5 surge protectors should be installed as part of outdoor Ethernet networks to guard against lightning strikes.


Ingress Protection Rating (IP Rating)


The IP Code classifies and rates the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in mechanical casings.


Solid particle protection


The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (for example, electrical conductors, moving parts) and the ingress of solid foreign objects.

Level Object size protected against Effective against
0 - No protection against contact and ingress of objects
1 >50 mm Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
2 >12.5 mm Fingers or similar objects
3 >2.5 mm Tools, thick wires, etc.
4 >1 mm Most wires, screws, etc.
5 Dust protected Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact
6 Dust tight No ingress of dust; complete protection against contact


Liquid ingress protection


Level Protected against Testing for Details
0 Not protected - -
1 Dripping water Dripping water (vertically falling drops) shall have no harmful effect. Test duration: 10 minutes

Water equivalent to 1mm rainfall per minute
2 Dripping water when tilted up to 15° Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position. Test duration: 10 minutes

Water equivalent to 3mm rainfall per minute
3 Spraying water Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. Test duration: 5 minutes

Water volume: 0.7 liters per minute
Pressure: 80–100 kPa
4 Splashing water Water splashing against the enclosure from any direction shall have no harmful effect. Test duration: 5 minutes

Water volume: 10 liters per minute
Pressure: 80–100 kPa
5 Water jets Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects. Test duration: at least 3 minutes

Water volume: 12.5 liters per minute
Pressure: 30 kPa at distance of 3m
6 Powerful water jets Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects. Test duration: at least 3 minutes

Water volume: 100 liters per minute
Pressure: 100 kPa at distance of 3m
7 Immersion up to 1 m Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion). Test duration: 30 minutes

Immersion at depth of 1m
8 Immersion beyond 1 m The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. Test duration: continuous immersion in water

Depth specified by manufacturer
