Traditionally the solution would have been four individual washer units makes demands in terms of space, maintenance and cost. The WA25-4 solves this challenge with one simple package ready to connect directly to your cameras.

Historically, a PTZ dome would have been used to view a 360-degree circle. With four fixed high-resolution IP cameras, that same circle can be covered with no chance of missing an event while the camera is pointing the ‘wrong’ way. Preserving the quality of image is essential and using a WA25-4 washer unit can form a crucial part of the system integrity. Why have millions of high-resolution pixels when they are obscured by dirt and grime?

Frequently Asked Questions

CCTV Washer Units - Functional

The most common reason for this is when you are using the switching power method to turn the washer on or off. If you are sure you are getting power to the unit correctly (and other factors such as fuses have been ruled out) have you checked to see if you have bridged the CONTROL inputs on the washer PSU. In the image a loop of tinned copper wire has been used.

Bridging the control inputs on washer PSU

These CONTROL connectors are only used to connect a device such as a telemetry receiver.

For more information download the manual from the product information page here.

We would always recommend that the washer control function is set to momentary, or at the very least timed.

Setting it to latching can result in the operating forgetting it is on and running the bottle out of water. Although the float switch feature will prevent the pump from burning out it will mean that you need to go and refill it far more often than you had planned.

The WA series washer units should be mounted below the camera or water jet output. If this is not possible then the water will drain out of the water reservoir after the pump has been activated. Its called siphoning.

We can offer an anti-siphon device which requires connection to the WA series washer. Contact our sales department for details.

CCTV Washer Units - Environmental

The standard WA series washers are manufactured from 304 grade stainless steel. This material is incredibly corrosion resistant in normal environments and will give years of service with no significant level of degradation.

If you are mounting the WA series washer in an area that is considered highly environmentally corrosive then you can consider 316 grade stainless steel. This is more commonly known as marine grade stainless steel and if you want to learn a bit more you can find out here.

Regardless of what grade of stainless steel you chose it can still discolour depending on the environmental conditions. Often customers can mistake a contaminant for rust when it is actually ferric particles that have landed on the stainless steel and discoloured. A simple rub with wire wool or even a cloth can often remove this.

 

Yes. We would certainly recommend a suitably diluted screen wash or anti-freeze additive in the water reservoir.

Allowing water to freeze in the water reservoir can cause the bottle to crack, just like on your car screen washer reservoir. Check the manufacturers recommendations for details of the dilution.

Always ensure you label the water reservoir correctly to reflect the use of poisonous substance.

CCTV Washer Series - WA25-4

The WA25-4 comes complete with four 12m lengths of hose, four twin washer jets and four mounting brackets. All you need is power and water.

CCTV Washer Series - General

If a screen is dirty the camera/lens if working in auto-focus mode will try and near focus on specs of dirt. The camera will try and fight that as clearly you are trying to view further than a few centimetres.

The tiny lens drive motors are not designed to keep working 24/7 and this will have an impact on their MTBF.

Having a clean screen will prevent this.

As standard all of our products have a 2-year warranty. This warranty is against manufacturing failure and has a couple of common-sense exclusions on the hose, the nozzle and the bottle.

All warranties on a back-to-base basis.

Yes.

All our products are designed by us on Solidworks 3D CAD software. We can provide you with simple PDF line drawings (some available on the site already) or any number of other formats including DXF, DWG, eDrawing etc.

Email sales@its-products.co.uk with your requirements and we will see how we can help.

There is no strict routine maintenance that needs to be observed for the WA series washers.

It is good practise to check the bottle for any algae build up, although this should be minimal if you are using a screen wash. You should also check that the hose is properly connected to the twin jet and the output spout.
