Description
The Ajax StreetSiren is a wireless external siren rated for permanent outdoor installation. Mounted on a front elevation at height, it provides the visible and audible deterrent that tells any would-be intruder the property is protected, and activates at up to 113 dB when the system triggers. That is loud enough to be heard clearly from the street, alert neighbours, and draw attention to the property in under a second.
This listing is for the Ajax StreetSiren in White, professionally supplied and installed by CCTV Aware, Ajax Certified Specialists covering Essex, London, Hertfordshire, and Kent.
Output and indication
The StreetSiren produces between 85 and 113 dB at one metre across a frequency range of 1.6 to 4.5 kHz, adjustable through the Ajax app by a PRO or an authorised user. The enclosure includes an LED frame rather than a single indicator, which strobes visibly during an alarm and also indicates the system’s security state during arming, disarming, and after-alarm periods. Alarm duration is configurable from three seconds to three minutes.
Hardened against tampering
The StreetSiren includes two layers of physical tamper protection. A tamper switch triggers if anyone attempts to open the enclosure. An accelerometer triggers if anyone attempts to move, shake, or wrench the siren from the wall, even before the enclosure is opened. Both events raise an immediate alert through the Ajax app and activate the siren itself if the system is armed.
Battery or mains power
Four pre-installed CR123A batteries provide up to five years of standby power, so the siren continues to operate during a mains failure or cut. For permanent installations where battery replacement is undesirable, the StreetSiren can alternatively be powered from a 6–20 V DC supply wired directly to the unit, with the batteries acting as a backup. It connects to your Ajax Hub 2 or range extender via Jeweller at a radio range of up to 1,500 metres, and is rated IP54 with an operating temperature range of −25°C to +60°C.

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.
