Description
The Ajax DualCurtain Outdoor is a weatherproof bidirectional curtain detector designed to protect gates, archways, driveways, and external door openings. Where a standard curtain detector monitors one direction, the DualCurtain monitors both sides simultaneously, with four independent IR sensors arranged across two separate detection zones. Each zone can be adjusted independently, so you can dial in the exact coverage you need for each side of a passageway without one zone interfering with the other.
This listing is for the Ajax DualCurtain Outdoor in White, professionally supplied and installed by CCTV Aware, Ajax Certified Specialists covering Essex, London, Hertfordshire, and Kent.
Bidirectional detection across a single mounting point
The DualCurtain is mounted facing the opening it protects, projecting a 4.5-degree horizontal, 90-degree vertical detection beam in each direction simultaneously. Range is adjustable between 4 and 15 metres per side using sliders on the rear panel, set independently for each zone. A near-zone detection option activates an additional downward sector, angled at 40 degrees, to eliminate the blind spot immediately in front of the detector. A 3-degree horizontal viewing angle shift is also available on each side for precise optical alignment without repositioning the mount.
Built for outdoor environments
The DualCurtain is rated IP54 and operates across a temperature range of −25°C to +60°C. Pet immunity applies to animals up to 80 cm in height. The SmartDetect and ELSA algorithms analyse each detection event to filter wind, foliage movement, and other environmental triggers before raising an alarm. Anti-masking protection detects obstacles placed within 10 cm of the lenses, painted-over lenses, or taped sides, and alerts you if anyone attempts to blind the detector before entering.
Battery life and connection
Two pre-installed CR123A batteries power the detector for up to four years. The Jeweller radio connection to your Ajax Hub 2 or range extender reaches up to 1,700 metres in open space, with encrypted two-way communication on a dynamic key.

Yes. We can install CCTV as discreetly as possible, depending on your property and coverage requirements.
Options can include:
- Compact camera styles
- Higher mounting positions where appropriate
- Tidy cable routes and minimal visible trunking
- Recorder installed out of sight in a secure location
If your priority is a low profile install, tell us at quotation stage so we can recommend the best approach for your layout.
The recorder (DVR or NVR) is normally installed indoors in a secure, sensible location with good ventilation.
Common locations include:
- A cupboard or utility area
- An office
- A comms cabinet or rack
We typically install it near your internet router if you want remote viewing on your phone, as it needs a network connection.
If you have a preferred location, let us know during the quote stage and we will advise if it is suitable.
In many cases, yes.
Whether you can add cameras later depends on:
- How many spare channels your recorder has
- Whether the recorder has spare capacity on the hard drive
- Whether cable routes and power options are available
If you think you might expand in future, we can design the system with this in mind, for example fitting an 8 channel recorder for a 4 camera install, or leaving suitable cable routes.
Yes. Your CCTV system records locally to the recorder (DVR or NVR). If your broadband drops out, it will still continue recording as normal.
What you will lose during an internet outage is:
- Remote viewing from your phone or PC
- Push notifications and alerts to your phone
- Remote playback access
Once the internet comes back online, remote viewing and notifications will resume.
Recording time, also known as retention, depends on a few things:
- Number of cameras
- Camera resolution (for example 6MP, 8MP)
- Recording mode (continuous 24/7, motion only, or a mix)
- Frame rate and bitrate settings
- The hard drive size fitted to your recorder
As a rough guide, higher resolution and 24/7 recording will reduce retention. Motion based recording can greatly increase retention, but it depends on how busy the scene is.
We generally specify our systems to give you a retention period of 21 days.
Hikvision CCTV systems can support a multitude of notifications that can be configured to perform various actions from alerting your mobile phone to activating a parking barrier.
That being said, this guide talks about the three main notification options.
Motion Detection
In its simplest form, this is when an object enters the camera view area and a motion is triggered.
Line Crossing
An invisible line can be drawn on a particular area of your camera view area, for example the driveway threshold or the garden boundary. Once an object crosses over that line (from either way) - a line crossing is triggered.
Intrusion Detection
This is similar to Motion Detection but more specific. With Intrusion Detection an invisible quadrilateral shape can be drawn on a particular area of your camera view, for example directly outside your front door. Once an object then enters that area - an intrusion detection is triggered.
With all of the options above, the system is unable to detect the difference between a human, pet or other object. This can often result in false notifications being triggered to the user. In addition to this, if the system generates the notification - it is then down to your broadband provider (router) to push the notification out to your mobile device. This will often fail if your provider is not quite up to scratch or your mobile phone is currently in an area with poor coverage.
Because of this, we do not provide support on notifications that are sent to your mobile device.
Unfortunately, no.
